Joe Biden is announcing a new target to cut US greenhouse gas pollution by at least half by 2030 as he convenes a summit of world leaders aimed at driving greater climate action.

The US president’s new target aims to achieve a 50-52% reduction in emissions from 2005 levels by 2030, a move which the White House said would create millions of jobs, cut energy costs and boost nature.
