Carbon emissions to reach new highs this year


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 carbon dioxide emissions appear to be going up strongly once again after a three-year stable period", said Corinne Le Quéré, a lead researcher of the 2017 Global Carbon Budget report and director of the Tyndall Centre for Climate Change Research at the University of East Anglia.

The report said the global emissions of Carbon dioxide from fossil fuels and industry were projected to rise by about 2% (with an uncertainty range of just between 0.8% and 3%) compared with the preceding year.

Pep Canadell, a geoscientist at Australia's CSIRO and head of the Global Carbon Project that produces the carbon budget report each year, says that the findings are disappointing. But China has invested hundreds of billions of dollars in developing its renewable energy sector while President Donald Trump has made clear his intention of aiding and abetting the fossil fuel industry's climate denialism and polluting activities.

Although pauses have been observed prior to 2014-16, Dr Canadell said these were typically correlated with global economic downturns such as during the global financial crisis.

The increase follows three years of flat emissions.

This year "might well prove a small blip on an otherwise flattening emissions curve", he said.

Data from the Department of Environment and Energy shows Australia's emissions have been increasing since 2013.

Australia has committed to reducing emissions to 26-28 per cent on 2005 levels by 2030. "That's a real concern", said Jackson On a positive note, the authors flagged that the emissions are unlikely to return to the persistent high growth rates, seen during the 2000s of over 3% per year, in the long term.

Much of the rise in carbon emissions this year was attributed to China in the report, which was presented at COP23 in Bonn, Germany. European emissions are expected to decline by.2 percent, which is also lower than the average decline of 2.2 percent per year.

"With global Carbon dioxide emissions from human activities estimated at 41 billion tonnes for 2017, time is running out on our ability to keep warming well below 2ºC let alone 1.5ºC", Le Quere added. India's emissions are projected to increase by around two percent - but that's down from more than six percent a year in the last decade. Meanwhile emissions from fossil fuels are set to reach 37 Gt CO2 - a record high.

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. Technologies-including wind and solar power-have surged about 14 percent each year in the last five years, though the starting point was low. In June he withdrew the United States from the 2015 Paris climate agreement, under which every other nation in the world has now agreed to limit climate change-causing pollution. It will help scientific community to develop methods and perform measurements that can verify changes in national emissions within the five-yearly cycle.
