New Zealand pledges to halve greenhouse gas emissions by 2030

With Cop26 climate summit about to begin, PM Jacinda Ardern says it's critical we pull our weight'

New Zealand has pledged to cut its net greenhouse gas emissions by 50% by 2030, toughening its previous ambitions to limit global warming on the eve of the United Nations Cop26 climate conference.

While we are a small contributor to global emissions, as a country surrounded by oceans and an economy reliant on our land we are not immune to the impact of climate change, so it's critical we pull our weight," prime minister Jacinda Ardern said in a statement on Sunday.
