In the lockdown, a breath of fresh air

One of the few positive spin-offs of the ongoing nationwide lockdown to combat Covid-19 has been a dramatic reduction in air pollution. Recent Nasa data reveals that air pollution in north India has dropped to a 20-year low. In Delhi, the levels of harmful microscopic particulate matter, PM 2.5, plunged after the lockdown began — falling from 91 mg per cubic metre (mg/m3) on March 20, to 26 mg/m3on March 27.

Nitrogen dioxide (NO2) released by vehicles and power plants also saw a significant fall of 71% during the period. The air in Delhi is now clear, the skies are blue, and we can hear birdsong again on the boulevards.

Unfortunately, these are but temporary gains, and should not distract us from the dangers of air pollution.

An urgent warning comes from a Harvard University study (, which establishes a correlation between long-term exposure to air pollution and Covid-19 mortality. The study finds that people living in polluted cities are more likely to have compromised respiratory, cardiac and other systems — and, therefore, are more vulnerable to Covid-19.

We should be very worried because India has 21of the 30 most polluted cities in the world. Air quality in some of our cities is 10 times over the safe limits recommended by the World Health Organisation (WHO) and, as per some estimates, air pollution claims more than one million lives each year.

Therefore, even as India flattens the infection curve, addressing the air pollution problem should continue to be a high priority for all policymakers. Today’s cerulean skies remind us that clean air and the right to breathe must be available to all citizens. And if India were to achieve this, there will be huge collateral benefits. We would not only become much more globally competitive, but we could also be well on our way to exceeding our climate ambitions outlined in the 2015 Paris Agreement.

There are many ways in which an economic revival package can get India to this Green Frontier. For instance, new investments could be directed towards renewable energy, with larger allocations and subsidies to initiatives like the National Solar Mission. We could adhere to deadlines for the Bharat Stage 4 standards and accelerate timelines and infrastructure investments for electric vehicle (EV) adoption.

Large electric battery factories could be established to enable localised energy storage solutions. Bailouts and incentives to the auto, aviation and construction sectors could encourage green transitions and clean air ambitions. The Energy Conservation Building Code (ECBC) in the residential sector could be enforced and a 2011policy relating to energy efficiency in MSME clusters could be integrated with the fiscal support to this sector.

Global experience suggests that crises create political opportunities for embracing change. After the 2008 global financial crisis, China spent nearly a third of its $568 billion stimulus towards projects that addressed environmental goals. China has since become a global leader in solar, wind and hydropower markets.

Britain and Germany also undertook green transformations post 2008 crisis. Similarly, India could use this Covid-19 crisis to undertake a far-reaching green revival.

We will find support. After the Covid-19 pandemic, there is a renewed focus on mega black and white swan shocks that can lead to immense loss of lives and destroy trillions of dollars of economic output. It is now much easier to convince policymakers, bankers and investors that awarming climate may well be the single-biggest macro shock the world will have to face. Green revival packages are bound to emerge around the world and global finance will inevitably align to this endeavour.

India is already the third-largest emitter of greenhouse gases (GHGs). Even optimistic predictions suggest that our emissions will nearly double in the next decade or so. A green revival package could be designed to ensure that India’s post-Covid economic resurgence becomes a key contributor in mitigating global emissions. It must be branded as the single-most important initiative for the world to meet and exceed Paris Agreement goals.

This will also give India more leverage in influencing the global financial community, and compel them to more pragmatically price risk, transparently rate creditworthiness, and bring down regulatory barriers that restrict the flow of capital to green projects in the developing world.

The battle for clean air requires structural reforms across multiple sectors, institutions and processes.

Public and private funds need to be redirected to green investments.

While temporary reductions in noxious emissions are certainly a huge relief, they are not the panacea for a country that has the onerous task of becoming the first $5 trillion economy in a carbon-constrained world. And, we must do this without gasping for breath.
