The survey revealed that India and China have seen a significant slowdown in expansion of coal, which is a major cause of pollution and causes approximately 12 lakh deaths in India annually.
"For the first time since the beginning of the global coal boom a decade ago, developments in East and South Asia - in particular China's wide-reaching restrictions on new coal plants and India's indication that no new coal power is needed - appear to have brought global climate goals within feasible reach, raising the prospect that the worst levels of climate change might be avoided," the survey said.
The survey authored jointly by the Sierra Club, Greenpeace and Coalswarm found that globally, there has been a 48 per cent decline in the overall pre-construction activity, a 62 per cent drop in new construction starts and an 85 per cent decline in new Chinese coal plant permits.
"This global slowdown in the coal power sector is a great opportunity for keeping global warming below 2 degree Celsius as per the Paris Agreement. Thus the commitment of achieving the 1.5 degree target looks more feasible," it said.

"In India, 31 coal plant units at 13 sites totalling 12,725 MW of capacity have been stalled, mainly due to frozen financing. Power demand in India has not kept pace with expanding capacity. Besides this, the declining cost of renewables has caused many financial backers of coal projects to withdraw support, leading to a further freeze in construction activity," the survey said.
While China has been cutting down on its coal consumption for the past three years and has vowed to cut 150 million tonnes of coal output capacity this year, India has gone a step "backward" with the recent news of postponing the implementation of emission norms for coal-fired thermal power plants, it said.
"Despite slowdown in construction of new plants and Plant Load Factors dipping to an all-time low, there are more than 170 GW of power plants under various stages of approval. India's Environment Ministry continues to clear further coal power projects and the government continues to stress upon its target of mining 1.5 billion tonnes of coal by 2020," said Sunil Dahiya, Campaigner, Greenpeace India.
expansion, the amount of coal power capacity under development worldwide saw a dramatic drop in 2016, mainly due to shifting policies and economic conditions in China and India.
"From being one of the countries most vulnerable to the impacts of climate change, India is now in a position to assume leadership in fighting both climate change and rising air pollution crises.
"Our ambition for massive upscaling of renewable energy is definitely a big step in the right direction, but we need to go the full mile by rationalising further investments on new coal but focus on reducing emissions from existing plants," said Dahiya.
"China has stopped new coal projects after the astonishing growth of clean energy has made new coal-fired power plants redundant, with all additional power needs ably covered from non-fossil sources since 2013.
"Closures of old coal plants drove major emission reductions especially in the US and UK, while Belgium and Ontario became entirely coal-free and three G8 countries announced deadlines for coal phase-outs," Myllyvirta said.
The survey said India experienced a slowdown in coal plant development, driven primarily by the reluctance of banks and other financiers to provide further funds.
"An end to the coal plant construction boom brings the possibility of a global phase-out of coal over the coming decades, a prerequisite to reining in climate change," the survey said.
In India, the Ministry of Power in June, 2016 said that the country had enough coal-fired plants to meet demand through 2019, and recommended that developers curtail their plans accordingly, the survey said.
The draft National Energy Plan, released in December, 2016, states that no further coal power capacity beyond that currently under construction will be needed until at least 2027.
"The combination of excessive coal power capacity and declining cost of renewables has caused many financial backers of coal projects to withdraw support.
"According to the Ministry of Power's December, 2016 Broad Status Report as well as additional reports from plant operators and photographic evidence, construction activity is now on hold for 31 coal plant units at 13 sites totalling 12,725 MW of capacity, mainly due to frozen financing," it said.
