With just five days left until leaders meet at the UN's COP26 climate talks in Glasgow, Scotland, dozens of nations have not yet officially updated their pledges to reduce emissions, as they are supposed to do under the rules of the 2015 Paris Agreement.
Of the G20 countries, which account for 80% of the world's emissions, only six nations have formally increased their targets. The report also found that six G20 nations, including the United States, never met their old targets. The others were Canada, Australia, Brazil, South Korea and Mexico.
The planet has already warmed 1.2 degrees, scientists say. The latest set of global climate pledges, according to the report released Tuesday, fall far short of what's necessary to limit warming to 1.5 degrees Celsius above pre-industrial levels — a critical threshold that scientists say the world should remain below.
The report found that new and updated pledges on emissions will only cut an additional 7.5% by 2030, but a 55% cut is needed to meet the goal of containing warming to 1.5 degrees.
Under countries' current targets, the world will continue to warm to 2.7 degrees, according to UNEP. "Countries have stretched, but they've not stretched enough," Inger Andersen, executive director of the UNEP, told CNN. "Many of them sort of kick the can down the road, and we need to see not pledges anymore we actually need to see real action."...
