Senior government officials at a climate meeting in Copenhagen gave a muted response Tuesday to calls from the head of the United Nations for countries to show greater ambition when it comes to reducing greenhouse gas emissions.
U.N. Secretary-General António Guterres urged rich countries Monday to bring forward their target for achieving net zero emissions as close as possible to 2040, and for emerging economies to aim for a date as close as possible to 2050. This would be a significant shifting of the goal posts: the United States and the European Union are currently aiming for net zero by 2050, while China is targeting 2060 and India has set a deadline of 2070.
