According to early projections by the Global Carbon Project, carbon dioxide emissions will increase a negligible 0.2 percent in 2016.
Regulations to decrease air pollution, a general economic slowdown, and a three-year ban on new coal mines have contributed to the decline of coal use throughout the country.
But, she warns, this reduction alone will not be enough to limit global warming to 2 degrees Celsius (3.6 degrees Fahrenheit) above pre-industrial levels that is part of the Paris climate agreement. Through its climate change programme, thousands of the world's largest companies disclose information on their greenhouse-gas emissions, energy use and climate change risks.
"It's unlikely that India's emissions will ever reach China's current levels", said Robbie Andrew, a climate economics researcher at the Centre for International Climate and Environment Research, Oslo (Cicero), and member of the Global Carbon Project consortium.
But America's 2015 emissions reduced by 2.6 per cent while China's were 0.7 per cent lower than 2014 levels, the researchers said.
Chinese emissions were down 0.7 per cent in 2015 and are projected to fall 0.5 per cent in 2016, the researchers said - noting Chinese energy statistics have been plagued by inconsistencies.
Such a move, although only likely in the longer term, would be "a significant first step" toward an worldwide trading system, putting a global price on carbon, said Mr Delbeke, one of the architects of the EU's emissions trading system. The United States, after all, has elected Trump, who has pledged to "cancel" the Paris climate agreement, which seeks to reduce emissions quickly, and to rescue the domestic coal industry, which relies on the mining and the burning of the most carbon-intensive fossil fuel. The new research credits China's efforts to decrease coal consumption as the primary cause of the emissions slowdown.
Environmental nongovernmental organization Greenpeace called on China and the European Union to step up their efforts to help cut global carbon emissions and take the lead on climate change matters this week, expressing concern over possible USA policy shifts following the election of Donald Trump as the nation's next president. Fossil fuels and industrial activity still contributed about 36 billion tons of heat-trapping carbon dioxide to our planet's atmosphere previous year.
"Nevertheless, the unexpected reductions in Chinese emissions give hope that the world's biggest emitter can deliver much more ambitious emission reductions", he said.
Mr Trump during the campaign vowed to "cancel" the Paris climate change accord reached past year.
And moreover, this flattening had occurred despite steady global economic growth above 3 percent, which has typically been coupled with higher emissions.
Good news for environmentalists concerned about Donald Trump's win: for the third consecutive year, global carbon emissions did not increase too much in 2016. There are two important reasons for emission staying stable even as economic activity has increased. However, this new analysis put out by the Global Carbon Project shows that emissions may be turning a corner.
Still, Peters said natural gas, wind and solar were likely to continue displacing coal in USA electricity production, thanks to new technologies and lower prices. Trump might pull out of the Paris agreement and disband the environmental protection agency. "One can only say with confidence that the next few years will be critical".
