Net zero possible in 2040s, says outgoing UK climate business expert

Countries that fear losing competitive edge could benefit from bolder climate policies, says Nigel Topping

The world could reach net zero greenhouse gas emissions in the early 2040s, substantially ahead of the mid-century climate target, if governments set more stretching goals and make bold policy decisions, the UK's outgoing climate business expert has said.

Nigel Topping served for two years as the high-level champion for the UK's presidency of the UN Cop26 climate summit, passing on the role to Egypt's Mahmoud Mohieldin late last year at the Cop27 summit in Sharm el-Sheikh.
