While carbon dioxide emissions from fossil fuel and industry in China are expected to rise about 3.5 per cent, after about two years of economic slowdown, India's contribution to the atmospheric build-up would go up by almost 2 per cent, the researchers have found.
"The past three years were quite exceptional in so far as that in the whole record, it's the first time that we saw emissions not growing at the same time as the global economy was growing quite strongly", he said.Worldwide, 21 countries, including the US, Denmark and France, have reduced their Carbon dioxide emissions over the last ten years while achieving economic growth.
The research reveals that global emissions from all human activities will reach 41 billion tonnes in 2017, following a projected 2% rise in burning fossil fuels.
"Having achieved the success of a global agreement to tackle climate change in Paris two years ago, these findings show that we need more than warm words in conference halls to tackle a warming world".
Researchers warned that the goals of the Paris pact could fall out of reach without concerted efforts to speed up the transition to a low carbon economy.
The researchers said there are uncertainties in our ability to estimate emissions changes - Glen Peters of the CICERO Center for International Climate Research and lead author on a study said it could take up to 10 years to independently verify a change in emissions based on measurements of Carbon dioxide atmospheric concentrations.
The increase is largely down to growth in coal-fired electricity generation, and oil and gas consumption in China, the scientists claim.
China's emissions added up to 28 percent of global emissions, which is expected to grow by 3.5 percent in 2017.
"Global commitments made in Paris in 2015 to reduce emissions are still not being matched by actions", said CICERO's Glen Peters.
He added that it was too early to be confident about the precise figure for China, which may range between 0.7 and 5.4% emissions growth. In 101 countries, emissions increased as GDP increased. "We do not know if the increase in emissions in 2017 is a one-off, or represents changes leading to more sustained upward pressure on emissions in the years ahead". This stable period, following a growth in emissions of more than 3% annually in the 2000s, fed hopes that many countries were succeeding in separating successful economy-building from increases in world temperatures.
Yang Fuqiang, senior adviser for the NRDC China Program, said the eventual carbon emissions of 2017 could be lower than forecast, as authorities have put on a large-scale production curb on industries such as steel and cement to combat air pollution during winter months.
Increases in coal use in China and the U.S. are also expected this year, reversing their decreases since 2013.
The world's rate of carbon emissions is rising again after staying steady for three years, according to a comprehensive study released today.
The research, published simultaneously in the journals Nature Climate Change, Earth System Science Data Discussions and Environmental Research Letters, shows that Carbon dioxide emissions are expected to decline by 0.4 per cent in the USA and 0.2 per cent in the European Union.
