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

Green Car Congress

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. Given currently available carbon budget estimates, the available global carbon budget for 1.5 ˚C GtCO 2 direct emissions and 0.28 C also on the table.
