India has pledged to the international community to reduce its emissions intensity - the amount of carbon dioxide released per unit of gross domestic product - by as much as 35 per cent from 2005 levels by 2030, and to increase the percentage of renewable energy in its power grids.
The construction of 65 gigawatts worth of coal-burning generation with an additional 178 gigawatts in the planning stages would make it nearly impossible for India to meet those climate promises, the researchers said.
By developing all of the planned coal-fired capacity, India would increase the share of fossil fuels in its energy budget by 123 per cent, researchers said.
"India's proposed coal plants will almost single-handedly jeopardise the internationally agreed-upon climate target of avoiding 1.5 degrees Celsius of mean global warming," Davis said.

If the country also met its goal to produce at least 40 per cent of their power from non-fossil sources in 2030, the total power being generated would greatly exceed its own projected future electricity demand, according to the new study.
"These plants therefore risk either locking out the country's renewable electricity goals or becoming stranded assets operating well below optimal rates and leading to financial losses," said Shearer.
"India's Paris pledges might be met if they built these plants and only ran them 40 per cent of the time, but that would be a colossal waste of money, and once built there would be huge incentives to run the plants more despite their contrary climate goals," Davis said.
Due to its low cost and accessibility of large domestic coal reserves, it is seen by the country as an aid in its quest to become a manufacturing and economic power and a way to provide electricity to the roughly 300 million people in the country who do not have it.
However, researchers stress there is significant downside to the fossil fuel habit. In addition to spewing harmful soot and other types of air pollution into the atmosphere, coal-burning power plants are the largest carbon dioxide source on the planet, making up 41 per cent of all carbon dioxide emissions in 2015.
