A new report released on Tuesday by the United Nations Environment Programme (UNEP) shows that global carbon dioxide (CO2) emissions rose again during 2017 after a three year hiatus, highlighting the imperative for countries to deliver on the historic Paris Agreement to keep global warming to below 2°C above pre-industrial levels.
The report comes just days before the key UN climate change conference known as COP 24, taking place in Katowice, Poland, with the agency urging nations to triple their efforts to curb harmful emissions.
The UNEP report comes hot on the heels of the watershed Intergovernmental Panel on Climate Change (IPCC) report on global warming, released in October, which cautioned that emissions had to stop rising now, in order to keep temperature increases below 1.5°C, and reduce the risks for the well-being of the planet and its people.
“If the IPCC report represented a global fire alarm, this report is the arson investigation,” said UNEP’s Deputy Executive Director Joyce Msuya. “The science is clear; for all the ambitious climate action we’ve seen – governments need to move faster and with greater urgency. We’re feeding this fire while the means to extinguish it are within reach.”
Heat-trapping CO2 gas in the atmosphere is largely responsible for rising global temperatures, according to the overwhelming body of scientific evidence. UNEP’s 2018 Global Emissions Report, show global emissions have reached historic levels.
Total annual greenhouse gases emissions, including from land-use change, reached a record high of 53.5 Gigatons in 2017, an increase of 0.7 compared with 2016.
“In contrast, global GHG emissions in 2030 need to be approximately 25 percent and 55 percent lower than in 2017 to put the world on a least-cost pathway to limiting global warming to 2°C and 1.5°C respectively,” said the report.
What’s worse, the report notes that there is no sign of reversal of this trend and that only 57 countries (representing 60 percent of global emissions) are on track to bridge their “emissions gap” – meaning the gap between where we are likely to be and where we need to be.
Increased emissions and lagging action means the gap published in this year’s report is larger than ever.
