According to current commitments to reduce greenhouse gas emissions, global temperatures will rise by 2.7 degrees Celsius by the end of the century, according to a United Nations report released on Tuesday.

At next week’s COP26 climate summit, world leaders will discuss more ambitious commitments to reduce greenhouse gas emissions, with the goal of limiting global warming to two degrees above pre-industrial levels.

The World Meteorological Organization, ahead of the two-week summit in Glasgow, which starts on Sunday, announced that the concentration of greenhouse gases reached record values ​​last year, and that the world is far from the limits of global warming.

The annual report of the United Nations Environment Program (UNEP), which measures the gap between expected emissions and emissions agreed by the Paris Agreement from 2015, states that the new promises of projected emissions for 2030 have been reduced by an additional 7.5 percent compared to previous commitments.

If the trend continues until the end of the century, the global temperature would increase by 2.7 degrees, which is slightly less than three degrees from UNEP’s last year’s projection.

A 30 percent reduction in greenhouse gas emissions is needed

A 30 percent reduction in greenhouse gas emissions is needed to limit heating to two degrees, as well as a 55 percent reduction to limit heating to 1.5 degrees.

The G20 countries, responsible for 80 percent of global emissions, will not meet the 2030 targets according to current indicators.

“If there is no significant reduction in emissions in the next decade, we will forever lose the opportunity to reach 1.5 degrees,” UN Secretary General Antonio Guterres told reporters.

“It is absolutely necessary that all G20 countries commit to a 1.5-degree reduction before or in Glasgow,” he added.

The latest UN data shows that 143 countries, which account for about 57 percent of global emissions, have submitted new or updated emission reduction plans ahead of the COP26 summit, which would lead to a 9 percent reduction in those countries’ emissions by 2030, compared to 2010.

But if all the promises of 192 countries under the Paris Agreement are taken together, global emissions are expected to increase by about 16 percent by 2030 compared to 2010, which would lead to a warming of about 2.7 degrees.

China and India, together responsible for about 30 percent of global emissions, have not yet committed to further reductions in greenhouse gas emissions.
