The Climate Action Tracker group says the new targets have reduced projected warming by the end of century by 0.2C. The forecast now stands at 2.4C – a small improvement, but higher than the 1.5C threshold nations are aiming for under the Paris climate agreement. Final calculations by researchers of the emissions gap in 2030 between Paris pledges and a 1.5C pathway show it’s been narrowed by 11-14%. The biggest prospective contributors to reducing emissions are the US, EU countries, China and Japan.
