The world will heat by more than 1.5C unless nations produce tougher policies, a global stocktake has confirmed. Governments must halve emissions by 2030 if they intend the Earth to stay within the 1.5C “safe” threshold. But the latest set of national policies submitted to the UN shows emissions will merely be stabilised by 2030. The UN Secretary-General, António Guterres, called it a red alert for our planet. He said: "It shows governments are nowhere close to the level of ambition needed to limit climate change to 1.5 degrees and meet the goals of the Paris (Climate) Agreement. "The major emitters must step up with much more ambitious emissions reductions targets."

"Global emissions have to be halved – but with current proposals they will only be stable. That’s really not good enough." Some nations have not even submitted a climate plan, and some – such as Australia – are judged to have offered no substantial improvement on previous proposals.
