In the United States, fossil-fuel emissions are projected to fall by approximately 0.4 percent this year, compared to an average decline of 1.2 percent per year over the past decade.
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.
"Global CO2 emissions appear to be going up strongly once again after a three-year stable period".
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.
"With global Carbon dioxide emissions from all human activities estimated at 41 billion (metric tonnes) for 2017, time is running out on our ability to keep warming well below two degrees Celsius, let alone 1.5 degrees Celsius", she said in a statement.
The lead researcher and director of the University of East Anglia's climate change department, Corinne Le Quere, called the projections "very disappointing".
Total carbon dioxide emissions from all human activities, which includes fossil fuels, industry, and land-use change, will reach around 41 billion tons in 2017, while emissions from fossil fuels alone will reach around 37 billion tons.
Odd-even gets NGT nod; no exemptions for two-wheelers, women, govt servants
Resorting to the odd-even scheme as a stop-gap arrangement will only work to disillusion the public from its marginal efficacy. The takeaway is fairly simple: Do not attempt easy solutions for complex, seemingly intractable problems.
"This is a window into the future", she said. "We need to reach a peak in global emissions in the next few years and drive emissions down rapidly afterwards to address climate change and limit its impacts", Le Quere said.
Carbon dioxide emissions are rising-again.
"The global economy is picking up slowly".
The Global Carbon Budget report, produced by a team of 77 scientists from 57 organisations around the world, brings together the most accurate information available each year about humanity's carbon output. One bright spot was a large drop in the growth rate of India's emissions (from 6% a year to 2%), though it is most likely temporary. The country's emissions are predicted to rise by 3.5% this year compared to 2016.
Flat emissions in recent years were particularly remarkable because they were accompanied by worldwide economic growth.
Technologies like wind and solar power have expanded across the globe by about 14 per cent annually in recent years, according to the report.
The goal set in Paris was to keep global temperatures from warming more than 2 degrees Celsius. "This demonstrates that we can not be complacent that the emissions would stay flat", Glen P Peters, Center for International Climate Research in Oslo (CICERO), said at a press conference in Bonn, where the current round of climate talks are under way.
