Putting a global price on carbon: Carbon Tax

WHAT’S A CARBON TAX, AND HOW DOES IT REDUCE EMISSIONS?

A carbon dioxide tax is a tax on businesses and industries that produce carbon dioxide through their operations. The tax is designed to reduce the output of greenhouse gases and carbon dioxide, a colorless and odorless incombustible gas, into the atmosphere. The tax is imposed with the goal of environmental protection.

Carbon is found in every kind of hydrocarbon fuel (including coal, petroleum and natural gas) and is released as the harmful toxin carbon dioxide (CO2) when this kind of fuel is burned. COis the compound primarily responsible for the “greenhouse” effect of trapping heat within the Earth’s atmosphere, and is therefore one of the primary causes of global warming.

Carbon taxes have been implemented in a number of countries around the world. They take several different forms, but most amount to a straightforward rate of taxation per ton of hydrocarbon fuel used. India has put Rs 200 per ton on coal as Carbon tax. 

A carbon tax aims to internalise the externality of climate change by setting a price on the carbon content of energy consumed or greenhouse gas emitted in the production or consumption of goods.

Carbon tax regimes will only be effective if harmonised internationally. Different country-wise policies could lead to ‘carbon leakages’ where energy-intensive businesses will most likely move to less strict national regimes.

Advantages of Carbon Tax over other regulation and control

First, a carbon tax regime avoids the problems related to choosing a baseline. In a price approach, the natural baseline is a zero carbon tax.

Second, a carbon tax policy will be better able to adapt to the element of uncertainty which pervades the science of climate change. Quantity limits on emissions are related to the stocks of greenhouse gas emissions, while the price limits are related to the flow of emissions.

From this uncertainty arises another complication of price volatility which is the third reason why a carbon tax policy is likely to cause less volatility in the prices of carbon emissions.

Fourth, quantity limiting policies are often accompanied by administrative arbitrariness and corruption through rent-seeking. This sends off negative signals to investors. In a price-based carbon tax, the investor has an assured long-term regulation to adapt to and can weigh in the costs involved.

Fifth, the most contentious issue in any international negotiation on climate change mitigation either at the level of the World Trade Organisation (WTO) or at the United Nations Framework Convention on Climate Change has been the issue of equity between high-income and low-income countries. The price-based approach in the form of carbon taxes makes it easier to implement such equity-based international adjustments than the quantity-based approach.

Renewables are not enough

Article Link

Summary:

World leaders, on April 22, ratified the global climate agreement reached in Paris last December. The agreement requires 195 countries to limit global warming to well below 2°C above pre-industrial levels, with the goal of not exceeding 1.5°C. The countries have also committed to “intended nationally determined contributions” (INDCs) to limit or reduce greenhouse-gas emissions by 2030.

About the agreement:

The Paris Agreement on climate change is a milestone in global climate cooperation. It is meant to enhance the implementation of the Convention and recognizes the principles of equity and common but differentiated responsibilities and respective capabilities in the light of different national circumstances.

  • The agreement acknowledges the development imperatives of developing countries. The Agreement recognizes the developing countries’ right to development and their efforts to harmonize development with environment, while protecting the interests of the most vulnerable.
  • The Paris Agreement recognizes the importance of sustainable lifestyles and sustainable patterns of consumption with developed countries taking the lead, and notes the importance of ‘climate justice’ in its preamble.
  • It seeks to enhance the ‘implementation of the Convention‘whilst reflecting the principles of equity and common but differentiated responsibilities and respective capabilities, in the light of different national circumstances.
  • The objective of the Agreement further ensures that it is not mitigation-centric and includes other important elements such as adaptation, loss and damage, finance, technology, capacity building and transparency of action and support.
  • Pre-2020 actions are also part of the decisions. The developed country parties are urged to scale up their level of financial support with a complete road map to achieve the goal of jointly providing US $ 100 billion by 2020 for mitigation and adaptation by significantly increasing adaptation finance from current levels and to further provide appropriate technology and capacity building support.

What’s good about this agreement?

  • Shared responsibilities: Unlike previous agreements which put all the responsibility for reducing emissions on rich countries, in the Paris Agreement, all 196 signatories agreed that every country must take action, while acknowledging that richer countries should start immediately and cut emissions more steeply, while poorer countries’ contributions will depend on their individual situations.
  • A “ratchet mechanism”: This is the technical term for the agreement to submit new pledges by 2020. It’s the most important victory within the agreement, as many large developing nations, like India and Indonesia, were reluctant to agree to a system that would pressure them to up their ambition within the next decade. The ratchet mechanism requires countries to return to the table in 2020 and spell out their plans for 2025 to 2030. This creates the opportunity for the world to potentially put itself on a course to stay below 2 C.
  • Ambitious abstract goals: The Paris Agreement includes the goal of keeping warming below 2 degrees C. But at the behest of the most vulnerable countries, such as the small island states, it also goes further, calling for efforts to stay below 1.5 C. It even requests that the Intergovernmental Panel on Climate Change produce a report on how we could stay below 1.5 C.

However, this agreement is far from sufficient. Why?

  • Various studies show that even if all INDC targets were achieved, the world would still be heading towards eventual warming of some 2.7-3.4°C above pre-industrial levels.
  • Over the past decade, energy productivity has grown by only 0.7% annually, and the share of zero-carbon energy rose by only 0.1 percentage point per year. Moreover, even if the INDCs were fully implemented, these annual growth rates would reach only 1.8% and 0.4 percentage points, respectively.

What needs to be done?

  • To keep warming well below 2°C, emissions in 2030 must be more than 30% below those envisaged in the INDCs. We must also reduce energy-related emissions by 70% from 2010 levels, with further cuts needed to achieve net zero emissions by 2060.
  • This will require both an improvement in energy productivity (the amount of income produced per unit of energy consumed) of at least 3% per year and the rapid decarbonization of energy supply, with the share of zero-carbon energy increasing by at least one percentage point each year.
  • Solar power can make a difference here. Solar power costs have fallen 80% since 2008. In some places, new supply contracts have set prices as low as $0.06 per kilowatt hour, making solar power fully competitive with coal and natural gas.
  • Investments in renewable capacity need to be matched by accelerated progress in battery technology, or by other tools to match electricity demand to intermittent supply.
  • Road transport and aviation, which currently rely almost entirely on liquid fossil fuels, account for 30% of total energy consumption. Decarbonization of these activities will require electrification or the use of hydrogen or biofuels.
  • Heating buildings is another area where major changes are needed. Here, the more widespread use of zero-carbon electricity, instead of fossil-fuel-based energy, could have a major impact. But there are also important opportunities to design and construct buildings and cities that are substantially more energy-efficient.
  • Energy use by heavy industry presents challenges that are often ignored. Metals, chemicals, cement and plastics are vital building blocks of the modern economy, and involve processes that cannot be easily electrified. Decarbonization may instead require the application of carbon capture and storage technologies, while newly designed building materials could reduce demand for carbon-intensive inputs.
  • Governments have a vital role to play, but so, too, do incumbent fossil-fuel-based energy companies and new-entrant companies deploying or developing new technologies. NGOs can help to identify required policies and hold governments and companies to account. Individual consumers are also important, because their behaviour shapes energy demand.

Conclusion:

The challenge now is to find an economically sensible path that enables emerging economies to fulfil their growing energy needs, while ensuring that the world meets its climate objectives. It is technologically possible. But it will require action by many very different actors. Unfortunately, climate change isn’t waiting. As the global temperature rises, glaciers are retreating, shrinking polar ice is threatening Arctic species, river and lake ice has been breaking up earlier, plants and animals are shifting ranges, and flowering cycles for trees are occurring earlier in the season. The signing of the accord, while historic, won’t solve those problems. It merely starts the world on the right, though very belated, path. The world needs to accelerate the pace.

Insure farmers against climate change

The Hindu

Issue

  • How India’s agricultural policy has made us structurally vulnerable to climate change?

India, a climate change hotspot

  • India is uniquely vulnerable to rising temperatures — it ranks in the top 20 in the Climate Change Vulnerability Index.
  • Our average surface temperature, over the past four decades, has risen by 0.3° Celsius, accompanied by a rising incidence of floods, droughts and cyclones.

How does climate change impact agriculture?

  • Climate change would impact soil health, with increasing surface temperatures leading to higher CO emissions and reducing natural nitrogen availability.
  • Mitigating this by increasing chemical fertilizer usage could impact long-term soil fertility, leaving the soil open to greater erosion and desertification.
  • Meanwhile, migration patterns, farmer suicides and stagnating rural incomes, along with increasingly ad hoc land acquisition in the name of public goods, have politicised the idea of climate mitigation.
  • Marginal farmland will increasingly be useless for agriculture.
  • Our regional crop patterns assume a specific range of weather variability, failing to cope with the recent high periods of heavy rainfall with long dry intervals.
  • India’s flood-affected area has doubled since Independence, despite generous state spending on flood protection schemes.
  • Climate change will impact the entire food production chain, affecting our food security.
  • Livestock production, often considered to be a substitute to farming for marginal farmers, would face reduced fodder supplies given a decline in crop area or production
  • Research has highlighted the deleterious impact of climate change on crop production.

What should be done?

  • Indian agricultural policy has made us structurally vulnerable to climate change.
  • A rural spending plan, focussed on investments in agriculture infrastructure, particularly in irrigation, rainwater harvesting and a national network of soil-testing laboratories is needed.
  • Simple water harvesting and conservation measures (micro-irrigation, watershed management and insurance coverage) can reduce the majority of the potential loss due to drought.
  • Drought strategies should be extended to the village level — for example, each village should have a village pond, created under the Mahatma Gandhi National Rural Employment Guarantee Scheme.
  • Conservation farming and dryland agriculture should be promoted.
  • Each village should be provided timely rainfall forecasts along with weather-based forewarnings regarding crop pests and epidemics in various seasons.
  • Afforestation, in a biodiverse manner, should be encouraged to help modify regional climates and prevent soil erosion.
  • Our agricultural research programmes need to be retooled towards dryland research.
  • Changing planting dates could have a significant impact; research highlights that planting wheat earlier than usual can help reduce climate change-induced damage.
  • Zero tillage and laser-based levelling can also help conserve water and land resources.
  • Crop planning can be conducted as per the climatic zones of different regions, while utilising better genotypes for rain-fed conditions.
  • We should focus on expanding our formal credit system to reach all marginal farmers.
  • Insurance coverage should be expanded to all crops while reducing the rate of interest to nominal levels, with government support and an expanded Rural Insurance Development Fund.
  • A debt moratorium policy on drought-distressed hotspots and areas facing climate change calamities should be announced, waiving interest on loans till farming incomes are restored.
  • The Centre and States should launch an integrated crop, livestock and family health insurance package while instituting an Agriculture Credit Risk Fund to provide relief in the aftermath of successive natural disasters.

Conclusion

  • With India’s population rising, demand for diversified crops will be hard to square with diminishing yields.
  • Agricultural investments in food crops, along with systemic support for irrigation, infrastructure and rural institutions can help move India beyond climate change-induced food insecurity, strengthening our stressed food production systems.
  • Through adaptation and mitigation measures, we can overcome this gigantic crisis.

Uttarakhand forest fires

Often unquantified, the social and economic impacts of forest fires are considerable: lives are lost, health problems occur, animals are killed and the environment suffers

The disaster:

Lives lost: 5

Land gutted by forest fire: Almost 1,600 acres of land (hundreds of villages/clusters)

Forest Fire in India:

Almost 50-55% of the total forest cover in India is prone to forest fire annually

Indian State of Forest Report, 2015: Tropical thorn forest, Tropical dry evergreen forest and Subtropical pine forest – most prone to forest fires

Period: Between February & mid-June

Why— Soil moisture is at its lowest

 

Himalayan Belt:

  • Western Himalayan region- moist deciduous, tropical dry deciduous, temperate and sub-Alpine types
  • Prone to fires owing to less rain in the pre-monsoon period
  • More susceptible trees: Pine forest in Garhwal & Kumaon Hills

 

Forest Fire & Ecology

  • The ground vegetation is completely destructed— severe loss of biodiversity
    • Loss of forest cover
    • Loss to the wildlife habitat
    • Loss of human lives
  • Emissions of Carbon in the Atmosphere (Climate change – lack of sustainable land use policy)
  • Expansion of deforested area— Change in landscape & micro-climate—Drying up of forest floor
  • Fires in the understorey of humid rainforests can cause tree mortality and canopy openness (Land transforms into ‘savannah’)

 

Major Issues related to Indian Forests:

Definition of Forest: No proper definition charted out with environmentalists and the government authorities having their own version of what exactly a forest is.

Greed for Land:

  • Increased industrial activity
  • Need to increase agricultural production
  • Nexus between land developers & Timber Mafia

Climate Change:

  • Natural Disasters: Volcanoes, Tsunamis, Earthquakes, Cloudbursts in Himalayas, Droughts, Storms
  • Mild winter: More pests and diseases (insect infestations)
  • The El-Niño effect: contributes to increases in the frequency of drought and lightning strikes

A recent study of various forest conditions in Russia suggests that a 2°C rise in temperature could increase the area affected by forest fires by a factor of between one and a half and two

India’s Efforts:

Intended Nationally Determined Contribution (INDCs): Pledged to

  • Increase its forest cover and improve the quality of forest cover
  • Create an additional carbon sink of 2.5 to 3 billion tonnes of Carbon Dioxide equivalent through additional forests and tree cover by 2030

Technology used for monitoring:

  • Satellite images to detect forest fires and its spread (INFFRAS)
  • Mapping of fire-sensitive zones as well as real-time data
  • Pre & post fire guidelines/warnings

Firefighting Techniques:

  • Clearance of stretches of ground vegetation in between forest areas to arrest the spread of forest fire
  • Beating the fire with the help of local community with specified certain equipment’s
  • Difficult to implement technique: Helicopters spraying water or carbon dioxide

Way Ahead:

  • The lack of regulatory enforcement and contradictory policies and laws need to be tamed in order to arrest the loss— ASEAN’s Zero Burning Policy needs to be reformed and given more teeth in order to keep the trend in check
  • Rural community is a major stakeholder and government should involve its large rural communities in preparing for the future— by utilizing effective intervention of community-led ‘van panchayats’ (forest councils) in preventing fires.
  • Usage of biomass alternatives, including cooking gas, has had a beneficial impact on fire risk, and this must be expanded
  • The plantation sector can be tapped for reducing the clearance of ecologically important natural oak forests, by giving preference to growing useful fodder and timber trees

Connecting the Dots:

  • What do you mean by Forest Degradation and Forest Fragmentation? How is the REDD Initiative related to the two?
  • Comment on the relationship shared between indigenous people and forests.

Cooling the earth down

Article Link

“Climate engineering” has been a buzzword in recent years. Environmentalists believe that climate engineering, along with reduction in carbon emissions, can greatly reduce global warming.

What is climate engineering?

Climate engineering, also known as geoengineering, describes a diverse and largely hypothetical array of technologies and techniques for intentionally manipulating the global climate, in order to moderate or forestall the (most severe) effects of climate change.

How is it being viewed currently?

Today, climate engineering efforts are viewed either as secondary measures to be undertaken alongside reducing emissions or as technologies which have not matured enough to warrant discussion by world leaders.

Climate engineering efforts can be divided into two categories:

  1. First, removal of Greenhouse gases from the atmosphere:

This basically involves management of carbon. A prominent example is carbon capture and storage (CCS), where some of the carbon dioxide (CO) being emitted by coal-fired power stations is recaptured by physically sucking it in and transporting it elsewhere to be sequestered underground.

Another method for removing CO from the atmosphere is to increase forest cover as plants will absorb some of the unwanted CO. Increased forestation is part of India’s strategy for reducing CO.

However, it is not clear whether CCS, reforestation and other carbon removal methods can make sufficient impact at the global level to significantly slow down global warming. But they seem relatively benign at the scale at which they are being considered now and will at least lower CO pollution locally.

  1. Second category involves Solar Radiation Management or Sunlight Reflection Methods (SRM):

This method aims to reduce the amount of heat trapped by greenhouse gases by reflecting sunlight back into space, either by increasing the reflectivity of the earth’s surfaces, or by deploying a layer of reflective particles in the atmosphere.

  • Among the techniques being considered under SRM are marine cloud brightening, cirrus cloud manipulation and stratospheric aerosol injection (SAI).

Stratospheric aerosol injection (SAI):

SAI, the boldest and also the most risky of climate engineering interventions, involves spraying into the stratosphere fine, light-coloured particles designed to reflect back part of the solar radiation before it reaches and warms the earth. SAI proponents claim that this could bring down the global temperature by as much as 1°C — a substantial amount in the climate change context. Many researchers have already verified this claim.

  • The optimal gases for injection, such as sulphur dioxide (SO), can be produced in abundance. Furthermore, just a few airplanes specially redesigned for the purpose may suffice for injecting the required aerosol into the stratosphere.
  • There are also precedents from nature. The 1991 volcanic eruption of Mount Pinatubo in the Philippinesinjected 20 megatonnes of SO into the stratosphere, cooling the globe significantly for a couple of years.

climate-engineering

Concerns:

  • However, SAI also has the potential for disastrous side effects, crossing national boundaries. The Pinatubo volcanic eruption is also said to have reduced precipitation, soil moisture, and river flow in many regions.
  • Also, injection of sulphur compounds into the stratosphere is likely to increase acid deposition on the ground and also contribute to ozone layer depletion. Apart from such “known unknowns”, there could also be, to use the catchphrase, the “unknown unknowns”.
  • Besides, once the aerosol has been injected into the atmosphere, it cannot be removed. Yet, if for any reason the injection, once begun, is discontinued prematurely, there can be rapid re-warming. That, ironically, could do more damage than the gradual global warming that we are seeking to combat.

Potential threats from SRM:

Worsening climate change may pressurize small nations to resort to using whatever SAI technology is available in the international market. In their desperation, possible harmful effects on other countries may not weigh heavily on their decision-making. Besides, just the fear of possible adverse side effects could lead to war between the nations.

How to deal with this problem?

One simple way to deal with this problem is to just ban further research in these fields. In fact, some climate scientists have already suggested this. They also fear that even the possibility of SRM interventions may undermine efforts to reduce carbon emissions.

Way ahead:

There are also few individuals who think that a blanket ban on SRM would be unwise and difficult to implement. Technology, benign or malevolent, has a way of continuing to advance.

  • The goal of SRM is to mitigate damage done by carbon emissions. If there is some chance of it succeeding safely, it would be unwise to abandon it at this stage.
  • Abandonment would also leave SRM technologies dangling midway, insufficiently tested or refined. That may nevertheless not deter some desperate climate change-afflicted nation from deploying it, leading to disaster.
  • It is only through continuation of responsible research in climate engineering, done under proper regulatory oversight, that the limitations and risks of such interventions can be fully understood and provide the basis for informed decision-making.
  • That will call for international governance mechanisms for overseeing the research and development and possible deployment of climate engineering techniques.

Conclusion:

The complexity of the issues associated with engineering the climate presents a challenge for shaping even the most basic research and engagements with the public and policy-makers today. It is difficult to predict how the debate on climate engineering will influence – or be influenced by – future developments in technology, the climate system, or the international order. While active climate engineering researchers have already been conscientiously worrying about these issues, it is not too early for the rest of us to start thinking about it.

Budget’s Impact on Renewable Energy

Article Link

This Budget has laid down the roadmap for taking India to the next level of growth. We not only see a clear direction in which the economy is going to be steered but also the key milestones that we need to cross on the way. Finance Minister Shri Arun Jaitley has identified 9 pillars for having a transforming impact on the economy and life of people which were – Agriculture, Rural Sector, Social Sector (healthcare), Education, Infrastructure, Financial Sector, Governance and Ease of Business, Fiscal Discipline, Tax Reform. The Budget was presented in the backdrop of an improving rural sector and infrastructure expansion; which were two of the prominent features of the Finance Minister’s Budget speech.

What’s in it for the Renewable Energy Sector?

The government has allocated an outlay of above Rs.10,000 crore for 2016-17 for the renewable energy sector. This outlay includes Rs.5,000 crore from the National Clean Energy Fund (NCEF) with the balance coming from Internal & Extra Budgetary Resource (IEBR).

  • A significant part of viability gap funding for solar power projects is intended to be financed out of such cash outlay.
  • The finance minister, in his speech, also mentioned diversification of sources of power for long-term stability and outlined his endeavour to augment investment in nuclear power generation in the long term. Changes have been proposed in the public-private partnership (PPP) mode to revive development of infrastructure.
  • On the taxation front, the clean environment cess on coal, lignite and peat has been doubled from Rs.200 per tonne to Rs.400 per tonne; encouraging the use of renewable sources of energy.
  • Other proposals include extension of benefit of additional depreciation to businesses engaged in the transmission of power and exemption of capital gains arising on account of the appreciation of the rupee against a foreign currency at the time of redemption of rupee-denominated bonds.
  • The final road map for phasing out of tax incentives has also been rolled out. No profit-linked incentives have been extended to the power sector, or renewable energy in particular.

What has been done so far for the Renewable Energy Sector?

At the UN Climate Change Conference held in Paris in 2015, India put forth its strong commitment towards clean energy and announced its climate change plan, i.e. Intended Nationally Determined Contribution (INDC) setting targets for domestic efforts against climate change.

  • Among other initiatives, key targets are 40% power installed capacity from non-fossil-fuel-based energy resources and reducing emissions by 33-35% of its GDP by 2030.
  • India’s INDC also sets a target of achieving 175 gigawatts (GW) of installed capacity of renewable energy—including 100GW of solar power and 60GW of wind power.
  • India also launched the International Solar Alliance (ISA), a coalition of solar resource-rich countries, to address energy needs and common concerns.
  • The Renewable Energy Global Investment Promotion Meet and Expo (RE-INVEST) organized in February 2015, received satisfactory response from global investors. India also signed an MoU with Germany to promote solar energy.
  • The government has also launched programmes, including the Green Energy Corridors, a nationwide transmission grid dedicated to power generated from renewable energy projects; setting up of 25 solar parks with a capacity of 50MW each; ultra-mega solar power projects scheme; and the viability gap funding scheme for setting up solar power projects by offering project developers capital cost support.

What’s holding India back from achieving the stated renewable energy targets?

A challenge remains in the capital funding required for such capacity expansion. With the finance minister deciding to stick to fiscal consolidation and reining in the deficit, India’s ability to further access debt resources is limited, due to an existing high debt ratio.

What else needs to be done to improve the energy sector (Renewable in particular)?

  1. Solve policy lag:

A lot of financing lined up for the deployment of wind and solar projects is stuck. This is due to lack of clarity at the individual state level on tariffs and policies preventing the execution of power purchase agreements (PPAs) in a time bound manner. This problem should be addressed soon.

  • Also, the renewable transition continues to be mired with litigation, discom financials and policy lag. Stressed projects are today a cause of systemic concern and there is a need to ensure that tribunal rulings are more or less binding and that going to courts is more a matter of exception than de rigueur.
  1. Capital allocation and incentives:

The extension of the 10-year tax holiday, inclusion of electricity under GST and clarity on domestic content requirement for renewables would help reduce the end cost of electricity to the consumer.

  • UDAY (Ujwal Discom Assurance Yojana) has the potential to transform the discom landscape but needs clear visibility on capital allocations and time bound focus on separation of content and carriage if the one off projected gains are to be sustained over a longer time frame.
  • Incentives and rebates should be given to the consumers to make solar an attractive and viable option. The solar rooftop industry will certainly need better non-recourse financing options by increasing power sector exposure limits of domestic banks.
  1. Need government reforms:

The government needs to design reforms in terms of pushing the initiative of biomass plants and more in 2016. Countries like Japan and India have identified a huge opportunity to further the energy cooperation across the energy value chain. The government needs to design reforms in terms of pushing the initiative.

  1. Push for solar power generation:

Also, the need of the hour is to create an effective ecosystem to enhance solar power generation capacity across India. While talking about rooftop solar in specific, extension of tax holidays, waiver of electricity duty and banking charge for solar rooftops, activating Renewable Energy Certificates (REC) benefits for rooftop projects and captive projects will certainly motivate more rooftop installations to come-up in cities and towns.

  1. Other reforms:

Enforcement of net metering guidelines across states and renewable purchase obligations, strengthening of grid infrastructure to accommodate intermittent solar power, and promoting storage solutions by way of incentives, subsidies etc.

Conclusion:

The recent budget appears to be focusing more on administrative issues within the limits of fiscal prudence, like providing a legal framework for dispute resolution in PPP projects and measures to curb litigation in order to promote a non-adversarial tax regime. However, in order to provide a fillip to the sector, especially in view of the ambitious targets for capacity enhancement set by the government, it should consider implementing the above mentioned reforms.

Decoding Emission Norms

Article Link

The Centre’s decision to adopt Bharat Stage VI automotive fuels nationwide by April 1, 2020 is a key measure that can, if implemented properly, vastly improve air quality. It also fits in with commitments made at the Paris climate change conference.

  • In November, the government had put in public domain a draft notification for implementation of BS-V and BS-VI emission norms for the automobile sector, covering the four wheeler category.
  • Implementation of the BS V standard was earlier scheduled for 2019. This has now been skipped. BS VI, originally proposed to come in by 2024 has been now advanced to 2020, instead.

What are Bharat norms?

Introduced in the year 2000, the Bharat norms are emission control standards put in place by the government to keep a check on air pollution. Based on the European regulations (Euro norms), these standards set specifications/limits for the release of air pollutants from equipment using internal combustion engines, including vehicles. Typically, the higher the stage, the more stringent the norms.

  • The BS IV norms were introduced in 13 cities apart from the National Capital Region from April 2010. Currently, BS IV fuel is being made available across the country in stages, with the entire nation expected to be covered by April1 2017.

Why is it important to upgrade these norms?

Upgrading to stricter fuel standards helps tackle air pollution. Global automakers are betting big on India as vehicle penetration is still low here, when compared to developed countries. At the same time, cities such as Delhi are already being listed among those with the poorest air quality in the world. The national capital’s recent odd-even car experiment and judicial activism against the registration of big diesel cars shows that governments can no longer afford to relax on this front.

  • With other developing countries such as China having already upgraded to the equivalent of Euro V emission norms a while ago, India has been lagging behind.
  • The experience of countries such as China and Malaysia shows that poor air quality can be bad for business. Therefore, leapfrogging to BS VI can put India ahead in the race for investments too.

BS-VI Norms:

  • The particulate matter emission in BS-V and BS-VI is same for diesel cars though it is 80% less than BS IV.
  • The nitrogen oxide (NOx) level is, however, 55% less in BS-VI over BS-V which in itself is 28% lower than BS IV.
  • The sulphur content in fuel norms for diesel and petrol under both BS-V and -VI standards does not change at 10 ppm, though it is substantially less than 50 mandated for both the fuels under BS-IV.

bharat-stages

 

 

Why we need these norms?

Major pollutants such as fine particulate matter, sulphur dioxide, nitrogen oxides and carbon monoxide emitted by millions of vehicles on India’s roads are severely affecting the health of people, particularly children whose lungs are immature and hence more vulnerable.

  • Thousands of premature deaths and rising rates of asthma episodes highlight the urgent need to make a radical and complete shift to modern fuels and vehicle technologies.
  • Past national policy of implementation of the BS IV fuel standard also failed primarily because this was not done all over the country and the technical standard also permitted a higher level of sulphur in the fuel.
  • Higher sulphur results in high volumes of fine respirable particulates measuring 2.5 micrometres (PM2.5) being generated in emissions.
  • Since even this obsolete standard was not followed uniformly, many vehicles, especially commercial passenger and freight carriers, have been using lower standard fuel supplied outside big cities. This has rendered their catalytic converters incapable of absorbing pollutants.

Other factors affecting the air quality in the country:

Improved air quality, especially in big urban centres, depends on several factors in an era of fast motorisation.

  • A bloated population of vehicles using fossil fuels has affected travel speeds, worsening pollution levels.
  • Poor civic governance has left roads unpaved and public spaces filled with debris and construction dust, constantly re-circulating particulate matter in the air.
  • Moreover, the monitoring of diesel passenger and commercial vehicles – the biggest contributors to total emissions – for compliance with emissions regulations remains poor.
  • Even, the distortions in urban development policy that facilitate the use of personal motorised vehicles rather than expanding good public transport, walking and cycling, are glaring.

Challenges before the government:

The government could face two key challenges in implementing the decision.

  • First, there are questions about the ability of oil marketing companies to quickly upgrade fuel quality from BS-III and BS-IV standards to BS-VI, which is likely to cost upwards of Rs 40,000 crore.
  • Second, and more challenging, is the task of getting auto firms to make the leap. Automakers have clearly said that going to BS-VI directly would leave them with not enough time to design changes in their vehicles, considering that two critical components — diesel particulate filter and selective catalytic reduction module — would have to be adapted to India’s peculiar conditions, where running speeds are much lower than in Europe or the US.
  • Also, the rollout model of introducing higher grade fuel and vehicles first in the cities has fundamental drawbacks, as was evident in the BS-IV implementation. In the periphery of designated BS-IV cities, BS-III vehicles could be registered; BS-IV vehicles (especially heavy vehicles) were more expensive, and BS-III fuel was cheaper than the BS-IV equivalent. And interstate trucks and buses, the biggest polluters, were forced to stay on with BS-III engines simply because the fuel outside cities did not conform to BS-IV norms.

Implications:

  • The three parties that are impacted by this decision are automobile, auto-components and petroleum refining companies. According to the government, oil PSUs would need to invest Rs 28,750 crore for the upgrade.
  • The problem for the automobile companies is a bit more complicated. Cars made by European and Japanese companies in India already comply with tougher fuel norms since these are exported to European nations. The problem lies with cheaper cars that cater largely to the domestic market.
  • Also, it will take at least three years of on-road testing with BS-VI fuel before cars can be cleared. That has more to do with Indian weather, traffic and road conditions.

What will change after the new norms kick in?

BS-IV norms are currently followed across 63 Indian cities for petrol and diesel. The BS-IV compliant fuels have sulphur concentration of 50 parts per million (ppm). This will come down to as low as 10 ppm in BS-VI compliant fuels and auto engines. This means a lower level of harmful emissions and reduced incidence of lung diseases.

  • The switch to BS-VI norms will also reduce concentration of carbon monoxide, unburnt hydrocarbons, nitrous oxide and particulate matter from emissions.
  • Finally, the quality upgrade will also result in diesel’s cost of production going up by 63 paise per litre and petrol by Rs 1.40 per litre. The switch will also make petrol vehicles costly by Rs 50,000 and diesel vehicles by Rs 1 lakh.
  • For consumers, this translates into higher retail prices of petrol and diesel.

Conclusion:

Rolling out the BS VI standard nationally, skipping BS V, has significant cost implications for fuel producers and the auto-mobile industry, but its positive impact on public health would more than compensate for the investment.

Building the International Solar Alliance

Article Link

India launched an International Solar Alliance (ISA) at the recently concluded CoP21 Climate Conference in Paris. The alliance brings together developed and developing countries, governments and industries, laboratories and institutions in a common enterprise.

  • While launching the alliance, PM Modi announced that the revolution in the field would bring power to all citizens, and create unlimited economic opportunity.

Aims of ISA: The main aims of ISA include reducing financial risk across a larger global market, encouraging cooperation on technology, building capacity, and increasing energy access.

Details:

  • All the countries, located fully or partly between the tropics of Cancer and Capricorn, have been invited to join the Alliance.
  • HQ: The new body will function from the National Institute of Solar Energy in India, Gurgaon.
  • The Union Government of India has announced that it will provide land and $30 million to form a secretariat for the Alliance, and also support it for five years.
  • Among the tasks that the Alliance would pursue are, cooperation in training, building institutions, regulatory issues, common standards, and investment including joint ventures.
  • To achieve its fixed objective, the Alliance needs between $1,000 and $1,200 billion over the next 15 years, of which 70% could be provided by the private sector. Public bodies are prepared to put up the balance. Both France and the Netherlands have also agreed to contribute, and other rich countries are set to follow suit.

Role of India:

  • India has a capacity of four gigawatts and has set a target of adding 100 GW of solar power by 2022. By the end of next year, India is also planning to add another 12 GW.
  • India has set the ambitious target of deploying non-fossil fuel electricity generating systems that supply 40% of the country’s cumulative installed capacity by 2030.
  • This new alliance is a sign of India’s leadership on the global stage. Under India’s leadership, the ISA could inspire and support several developed and developing countries to advance on a clean energy pathway by lowering financing costs, developing common standards, encouraging knowledge sharing and facilitating R&D collaborations and co-development of technologies to meet the Sustainable Development Goals (SDGs) announced earlier this year.
  • This initiative has also demonstrated that India is not shy of playing to its strengths. Although other countries have more solar power deployed currently, India will be one of the largest markets and its domestic policy (to build 100 gigawatts) has sent signals to developers and financiers.

Road ahead for ISA:

However, International Solar Alliance is one among many multilateral and plurilateral initiatives, which have been launched in recent years. Other initiatives include the International Renewable Energy Agency, Renewable Energy Policy Network, Renewable Energy and Energy Efficiency Partnership, Global Green Growth Institute, and so on. As the newest inter-governmental institution in the world, it is imperative that ISA carves a niche for itself and demonstrates genuine value to its members.

For the alliance to be successful, it is necessary to consider implementing the following steps:

Select a director general (DG) with a secretariat: A dynamic DG can draw attention to the alliance, build relationships with member states and other international institutions, interact with the media regularly, and develop a strategic plan. The appointment of a DG will take time and will require consensus among member states. But a good choice would make the difference between leadership that can articulate and execute a vision and one that fails to grasp ISA’s potential.

Create a core ISA coordination group: Since its launch, the ministries of new and renewable energy, external affairs and other agencies have been discussing informally and working together to keep the ISA wheels moving. However, since the world is looking at how this evolves, a dedicated inter-ministerial group will be needed to distribute the workload, allocate funds, maintain contact with member states, and prepare related documents.

Issue a white paper on ISA governance: ISA is an inclusive multilateral institution but there is as yet lack of clarity on its governance structure. A paper outlining alternative governance models would draw in ideas from member states and other stakeholders and inform deliberations in subsequent meetings.

Launch an ISA website: It should feature the ISA declaration, list of members and observers, minutes of meetings, proposed activities, a meeting calendar, governance structure, and, eventually, outcomes of ISA activities.

Issue monthly ISA briefings: Until a dedicated DG and secretariat are in place, regular press briefings and monthly updates to all ISA member countries would build support. The more ISA is in the news, the more its activities and potential will get attention.

Assess all proposals through a “value-add” lens: A number of ideas are beginning to come forward on what other institutions (private, public and inter-governmental) could do to shape ISA’s agenda, such as mobilising investments or deploying projects in member countries. It is important that ISA activities do not overlap unnecessarily with those of other organisations. A “value-add” perspective – and measuring each initiative against stated aims – would help ISA specify its unique proposition for the benefit of members and investors.

Kick-start bold initiatives: It would be useful to launch one or two bold initiatives, which could capture the imagination of ISA members. This could trigger interest from innovators, project developers, bankers and other investors.

Establish formal links with private sector platforms: many other renewable energy-focused organisations do not have strong links to the private sector. ISA can distinguish itself by giving private sector consortia observer or associate member status, encouraging them to design and implement ISA programmes, and build relationships for targeted investments.

Announce an ISA summit and expo: An annual or biennial summit and expo would draw further interest.

Build an ISA headquarters in New Delhi: ISA will need its recognisable location, branding and identity. The headquarters’ design should convey ISA’s vision, its open and inclusive governance, its emphasis on practical solutions and scale, and its purpose of delivering clean energy access to millions.

Conclusion:

Today, when the energy sources and the excesses of our industrial age have put our planet in peril, the world must turn to Sun to power our future. Solar technology is evolving, costs are coming down and grid connectivity is improving. The dream of universal access to clean energy is becoming more real. And the launch of Solar Alliance will be the foundation of the new economy of the new century. And hence this initiative can be seen as a step in the right direction.

El Niño, the ‘Godzilla’ warming the winter?

More than half the winter is gone and most of India has hardly even noticed the cold. Temperatures are 4-5 degrees Celsius above the normal for this time of the year.

This could turn out to be the warmest winter in India in several years. Scientists are blaming both global and regional/local factors. Globally, it is the persisting El Niño phenomenon, one of the strongest ever, that is believed to be having a warming effect over the Indian subcontinent. The warmer winter in India is part of a global weather pattern dictated by an unusual warming of ocean waters thousands of miles away.

At the more local level, the lack of winter rain, caused by a combination of atmospheric processes — some of them unexpected and unusual at this time of the year — has kept the chill away.

El Niño refers to a condition in the equatorial Pacific Ocean, off the coast of Peru and Ecuador, in which sea surface temperatures become unusually warm. This warming of the sea influences weather events across the globe, resulting in enhanced rainfall in the US (California) and Europe (Britain), and dry spells in India, Indonesia and Australia. Some of the worst wildfires in Indonesia have occurred this year, are being attributed to the El Niño.

The current El Niño, however, is one of the longest and strongest ever. By the time neutral conditions are expected to be established in the Pacific Ocean later this year, the El Niño would have persisted for 15 months, spanning two seasons. Some scientists had called it a “double El Niño” last year.

The Absent Westerlies

The last week of December and first week of January see rain in most of Northern and Eastern India. It pulls down temperatures, and introduces a chill in the air. This rain is brought by the Westerlies, a wind system that moves in the mid-latitudes, 30 to 60 degrees, in the northern hemisphere from west to east. These winds shift slightly southward during this time, and flow through most of northern and central India.

This year, the Westerlies have been kept north of the Indian landmass by two different wind systems.

  1. An anticyclonic wind system (High pressure system) that is usually located south of the Indian peninsula has been pushed northward, and is located where the Westerlies are usually found at this time of the year. This anti-cyclonic system is warmer and drier.
  2. Around the same latitude, but much higher in the atmosphere, are located another wind system called the Jetstreams. The Jetstreams, also moving west to east, are found in the upper troposphere, between 5 km and 12 km above the earth’s surface. These generally operate in the mid-latitudes, north of the Indian landmass. But this year, they are positioned much to the south, aligned to the foot of the Himalayas and the Gangetic plains. 
  3. These two systems together have prevented the penetration of the Westerlies into northern and central India, thereby denying these areas their winter rain.
