Nations' climate goals take shape

摘要

US PRESIDENT Joe Biden has committed the world's second-biggest greenhouse gas producer to cutting its emissions by up to 52 per cent by 2030, in a significant boost to the country's climate change ambitions. The move was announced last week at the US-hosted virtual Leaders Summit on Climate, where Japan and Canada upgraded their targets and 40 heads of state agreed about the urgent need to rein in emissions. The new US goal - a 50 to 52 per cent drop from 2005 levels - is part of a wider effort to elicit new pledges ahead of the UN's COP26 climate summit in Glasgow, UK, in November. One of the conference's key focuses is closing the gap between the Paris Agreement's goal of holding global warming to 1.5°C and the roughly 3°C the world is currently on track for.
