According to Environment Performance Index (EPI) 2024, what was India's rank in greenhouse gas production in May 2024?
7th
2nd
3rd
11th
3rd
According to the 2024 Environmental Performance Index (EPI), India holds the 3rd rank in total greenhouse gas (GHG) emissions, trailing only China and the United States. This ranking is based on the absolute volume of anthropogenic emissions measured in terms of carbon dioxide equivalents.

Think of the atmosphere like a car parked in the sun with windows rolled up; the glass lets sunlight in but traps the heat inside, much like how GHG molecules trap thermal radiation in the Earth's atmosphere.
C-U-I (China, USA, India) - The world's top three GHG producers.
╬ФF=╬▒ln(C0тАЛCтАЛ) тАФ The radiative forcing formula where C is the concentration of GHG and C0тАЛ is the reference concentration.
EtotalтАЛ=тИС(GHGiтАЛ├ЧGWPiтАЛ) тАФ Total emissions calculated by multiplying the mass of each gas by its Global Warming Potential (GWP).
The accumulation of greenhouse gases (GHGs) like CO2тАЛ, CH4тАЛ, and N2тАЛO leads to an enhanced greenhouse effect. When solar radiation strikes the Earth, the surface emits infrared radiation which these gases absorb and re-radiate back to the surface, causing global temperature increases governed by the radiative forcing principle: ╬ФF=╬▒ln(C0тАЛCтАЛ).
The EPI evaluates 180 countries on 58 performance indicators across climate change, environmental health, and ecosystem vitality.
The primary drivers for India's rank are industrial coal consumption and the expanding energy requirements of its growing population.
Greenhouse gases are measured in CO2тАЛe (carbon dioxide equivalent) to normalize their global warming impact.
Quantifiable data allows nations to track climate progress.
Helps in policy formulation for transition to renewable energy sources.
Does not always account for historical emissions responsibility.
Absolute emission rankings can penalize developing economies with large populations.
Climate change mitigation strategy development.
International climate policy negotiation (UNFCCC/COP meetings).
The index is produced by the Yale Center for Environmental Law & Policy and the Center for International Earth Science Information Network (CIESIN) at Columbia University.
Option A, B, and D are incorrect as they do not reflect the current data released in the 2024 report regarding absolute volume.
C is correct тАФ India is ranked 3rd globally in terms of absolute greenhouse gas emissions according to the 2024 EPI data.
For competitive exams, always distinguish between 'Absolute Emissions' (where India ranks high due to scale) and 'Per Capita Emissions' (where India ranks much lower compared to developed nations).
