The story so far: On the final day of the UN Climate Change Conference held in Glasgow , India’s Minister for Environment Bhupender Yadav read out a statement promising to “phase down” rather than “phase out” the use of coal . This caused many to raise questions about India’s commitment to tackling climate change. Earlier, during the COP26 (Conference of Parties) summit, Prime Minister Narendra Modi had committed to turning India carbon neutral by 2070.
Why must dependence on coal be reduced?
Since carbon emissions are considered the main culprit in global warming, countries have been committing themselves to turning carbon neutral by various dates. One key way to achieve carbon neutrality, wherein countries compensate for their carbon emissions by capturing an equal amount of carbon from the atmosphere, is to reduce dependence on coal. Coal is the most polluting among fossil fuels, and hence, its use in particular has come under scrutiny.
Why is it difficult?
Coal is used to meet over 70% of India’s electricity needs. Most of this coal comes from domestic mines. In FY 2020-21, India produced 716 million tonnes of coal, compared with 431 million tonnes a decade ago. Since FY 2018-19, domestic production has stagnated and has been unable to meet the rising domestic demand, leading to a rise in imports. Most of the country’s coal production is limited to Chhattisgarh, Odisha, Jharkhand and Madhya Pradesh with a total production of over 550 million tonnes, contributing to over 75% of the country’s total coal production. The Prime Minister promised to increase non-fossil fuel energy capacity to 500 GW by 2030, meet 50% energy needs from renewable sources and reduce carbon emissions by 1 billion tonnes in a decade. According to an estimate by the Centre for Science and Environment, the promise to reduce emissions by 1 billion tonnes means that India would need to reduce its carbon output by 22% by 2030. India now meets about 12% of its electricity needs from renewable sources, and increasing it to 50% by 2030 will be difficult. While some renewable energy sources like solar are cheap, they are unreliable because of the intermittency problem. They thus require the use of storage batteries, which adds to the cost. It should be noted that many low-income countries with low savings may not even possess the capital required to invest in renewable energy. Further, the damage that coal causes to commonly owned resources like the environment is not factored into its cost. So, there is not much economic incentive for countries to limit or to end their massive reliance on coal.
Is it fair to ask India to phase out coal?
India has fought attempts by developed countries to impose a cap on its emissions. It has argued that adopting stringent steps to reduce carbon emissions can drag down growth and affect efforts to reduce poverty. It should also be noted that per capita carbon emissions of countries such as India and China are still lower than those of many developed countries. According to World Bank data of 2018, India produces 1.8 metric tonnes of carbon emissions per capita against 15.2 metric tonnes produced by the U.S. High-income countries in general emit over 50 times as much carbon as low-income countries and over six times as much carbon as lower middle-income countries. Experts believe India’s commitment to phase down coal and become carbon neutral may actually be a rather generous commitment than what developed countries have committed themselves to. Critics have also pointed out that the focus on ending the use of coal deflects attention from other fossil fuels such as oil and natural gas that are heavily used by developed countries. They also say developed countries have not made good on their promise made at COP15 in Copenhagen to offer $100 billion every year to developing countries to achieve net zero emissions.
What lies ahead?
It is highly unlikely that developing countries like India and China will reduce their coal consumption or even stop it from rising further. Coal, after all, is the cheapest and most reliable way to meet their rising energy needs. Further, the pledges made by countries at COP26 to reach net zero emissions or to phase down coal are not legally binding. The target dates to achieve these climate goals also lie so far in the future that most of today's political leaders won't be around when the deadlines arrive. Some leaders have proposed a carbon tax as an alternative to ensure that the price of coal reflects the cost of the damage it causes to the environment. This may turn out to be a more effective approach towards reining in carbon emissions. Coal on average is priced at $2, while experts believe that it should be priced in the range of $30 to $70 to reflect its true cost. But such high carbon taxes can cause a drastic fall in coal output and severely affect living standards unless alternative sources of energy step in to fill the gap. India also faces its own set of structural problems in the power sector that will make the transition towards clean energy harder. The pricing of power, for instance, is influenced by populist politics which may hinder private investment in renewable energy.
