STOCKHOLM, Muharram 25, 1437, November 07, 2015, SPA -- The U.N.'s environmental authority has quietly raised its assessment of the level at which global greenhouse gas emissions must peak to avoid dangerous climate change, as governments seek a new accord to fight global warming, AP reported. In its first four annual emissions reports in 2010-2013, the United Nations Environment Program said emissions must not exceed 44 billion tons in 2020 for the world to limit global warming to 2 degrees C (3.6 degrees F). But with real-world emissions rising far beyond that level, UNEP has since last year downplayed its focus on 2020 as a make-or-break year for emissions reductions. In this year's Emissions Gap report, a summary of which was released Friday, UNEP says the world can still reach the 2-degree target with emissions of 52 billion tons by 2020, which is just slightly below today's level. The new analysis assumes that emissions cuts will drop faster after 2030 than was assumed in previous reports. --SPA 02:06 LOCAL TIME 23:06 GMT www.spa.gov.sa/w
