CO2 emissions to rise in 2018

Energy sector carbon emissions will rise in 2018 after hitting record levels the year before, dimming prospects for meeting Paris climate treaty goals, the head of the International Energy Agency (IEA) said Wednesday.

The energy sector accounts for 80 percent of global CO2 emissions, with most of the rest caused by deforestation and agriculture, so its performance is key to efforts to rein in rising world temperatures.

"I'm sorry, I have very bad news for you," IEA Executive Director Fatih Birol told guests at a diplomatic function hosted by the Polish embassy in Paris.

"Emissions this year will increase once again, and we're going to have the COP meeting when global emissions reach a record high," he said, referring to the December UN climate summit in Katowice, Poland.

After remaining flat for three years, total global CO2 emissions in 2017 rose by 1.4 percent, dashing hopes that they had peaked.

The meeting in Katowice is tasked with finalising the "operating manual" for the 195-nation Paris Agreement, which enters into force in 2020 and calls for capping global warming at "well below" two degrees Celsius (3.6 degrees Fahrenheit), and at 1.5 C if possible.

"The chances of meeting such ambitious targets, in my view, are becoming weaker and weaker every year, every month," Birol told invitees.
