As a rapidly developing nation, India is currently the world’s fourth-largest emitter of greenhouse gases. However, we aim to reduce the overall carbon intensity and achieve 50 per cent of power from non-fossil fuel sources by 2030, which is currently at 43 per cent as per Central Electricity Authority (CEA).

The National Green Hydrogen Mission envisions India to be a leading manufacturer and a major hub for green hydrogen in the world. However, India lacks the necessary infrastructure and some of the key technologies that are needed to realise these goals. India does not produce green hydrogen at a commercial stage at present and lacks several raw materials (critical minerals) that are required to manufacture electrolysers.

The growth of the Indian petrochemical industry can be made sustainable only by mitigating the emissions from it. This study examines the decarbonisation potential of India’s petrochemical sector until 2050 through low- or zero-emission technologies. It also underlines measures for decarbonising this hard-to-abate sector, with the aim to provide inputs for devising suitable strategies and guide policy formulation.

The on-road vehicle stock in Bengaluru is expected to grow by 1.5 times, with the total vehicular population projected to increase from 5.7M to 8.9M by 2030. Of note, the city’s electric vehicle (EV) fleet is projected to grow from 75,000 to 2.3M, with the most significant increase in the number of two wheelers, followed by three and four wheelers.

Greenhouse gas (GHG) emissions are a direct cause of human-induced climate change. India accounted for 2.9 billion tonnes of CO2 emissions in 2019. The transportation sector accounts for roughly 10% or 290 million tonnes of CO2 emissions per year. Road transport, mainly comprising heavy vehicles (buses and trucks) and to some extent personal vehicles (two wheelers [2Ws] and four wheelers [4Ws]), is the leading contributor to these emissions.

The relationship between climate change and migration is intricate. The first article in our ‘Under the Weather, On the Move’ series talked about the context and conditions within which people move or do not move. Establishing migration as a layered phenomenon, it further discussed how climate change impacts are diverse and closely linked to experiences of identity and sociocultural norms.

The world is grappling with intensifying climate change — temperatures are rising, weather patterns are changing, and extreme events and natural disasters are becoming frequent.
We are in the climate decisive decade, and we must act now.

The fifth India Clean Air Summit (ICAS) — the Center for Study of Science, Technology and Policy’s flagship event on air pollution — will be held from 22–24 August in Bengaluru. This year’s summit promises to be just as (if not more) informative, insightful, and engaging as the previous ones.
