Global carbon emissions ‘to stall or even decline’ this year

Global emissions of carbon dioxide are likely to stall and even decline slightly this year, new data suggests. Researchers say it is the first time this has happened while the global economy has continued to grow. The fall-off is due to reduced coal use in China, as well as faster uptake of renewables.
Scientists expect the stall to be temporary and for emissions to grow again as emerging economies develop. According to the study, published in the journal Nature Climate Change and presented here at COP21 in Paris, emissions of carbon dioxide from fossil fuels and industry are likely to have fallen 0.6% in 2015.
Since 2000, global emissions have grown annually by 2-3%. The slowdown has occurred while the global economy has grown by 3% in both 2014 and 2015. "We’re expecting a stalling in emissions, possibly even a little decrease," said Prof Corinne Le Quere from the University of East Anglia, UK, who led the data analysis.
"The main cause is from decreased coal use in China. It’s restructuring its economy, but there is also a contribution from the very fast growth in renewable energy worldwide, and this is the most interesting part: can we actually grow renewable energy enough to offset the coal use elsewhere?"
China continued to be the world leader in emissions, according to the report, responsible for 27% of the global total. With its economy slowing, coal use has declined just as concerns have grown over air pollution issues in urban areas. There has also been a rapid take-up in renewables. However, Prof Le Quere said that despite this year’s figures, the global peak of emissions use was not yet in sight.
"As the emerging economies are mostly based on coal, as they grow we are expecting a restart in the emissions," she told BBC News. "And in the industrial economies like in the UK, where emissions are going down, the decrease is relatively modest, mostly 1-2%. We would be looking for a much faster decrease than that to offset the growth in the developing countries."
