1. Emissions matter, not the particular fuel source they come from. Most places cannot meet 100% of their needs, or even 100% of their growth in needs, with renewables so they must use and even grow some fossil fuel sources.
India has vast coal reservers, and is the second largest producer in the world, whereas they aren't a major oil producer. Hence they use coal. Similar with China.
If the story was about some country shutting down their last natural gas plant instead of their last coal plant, no doubt someone would be pointing out that meanwhile the US is increasing natural gas production at a record pace.
In 2025 the US added 7 GW of natural gas electricity capacity, and India added 7 GW of coal. Natural gas generates about 1/2 the CO2 as coal, but India has over 4x the population, so the US added about twice as much new emissions per capita.
But we also need to consider how much renewables were added. That will be part of point #3.
2. India's emissions are 2 tons per year per capita, which is under 1/2 of the global average, which is about 1/3 the EU average, 1/5 of China, and 1/7 of the USA. Even if it takes them longer to get off fossil fuels than the other large countries they are likely to never come near the emissions levels per capita of those other countries.
3. They are actually making better progress at this than most others. 50% of electricity used in India is renewable, compared to 25% in the US, 40% in China, and 47% in the EU.
They are not just adding coal. They are adding wind and solar at record paces too. In 2025 they added around 7 GW of coal capacity last year, 38 GW of solar, and 6 GW of wind.
The US is doing the same, but with natural gas rather than coal. 7 GW of natural gas, 25 GW of solar, 13 GW of wind. About the same percentage of renewables (~90%) as India.
4. Yes, per capita is the correct measure, because the atmosphere is very efficient at distributing CO2 emitted anywhere to everywhere. A ton of CO2 has the same impact no matter where it is emitted. Unless you can make a good argument that some people have some sort of natural or divine right to a bigger share of whatever CO2 budget we decide Earth can afford, it has to be per capita.
