Air Pollution and India's Efforts to Combat Emissions
Some power plants in India that burn coal don't have to clean up the pollution they make.
Sulfur dioxide (SO2) mixes with other stuff in the air to make tiny particles (PM2.5) that are bad for you.
Breathing in too much SO2 can hurt your eyes, throat, and lungs and can even cause heart problems.
SO2 also makes acid rain, which harms the environment.
India is also trying to build more ways to make electricity that don't use fuels like coal.
India's Environment Ministry exempted most coal-based thermal plants from installing SO2 emission removal systems.
SO2 reacts with ammonia to form ammonium sulfate, a major component of PM2.5 pollution.
Exposure to high levels of SO2 can irritate eyes, throat, and lungs, and increase the risk of heart attacks.
SO2 contributes to acid rain, damaging ecosystems, but carbon monoxide does not.
India aims to install 500 GW of non-fossil fuel-based electricity capacity by 2030.
