UN Environment report says national GHG pledges only bring one-third of reductions needed for Paris Agreement

Green Car Congress

The Paris Agreement looks to limit global warming to under 2 ˚C, with a more ambitious goal of 1.5 ˚C If the emissions gap is not closed by 2030, the report says, it is extremely unlikely that the goal of holding global warming to well below 2 ˚C can still be reached. C also on the table. C will already be well depleted by 2030.
