Global greenhouse gas emissions must peak by 2025 and drop sharply thereafter if humanity is to cap global warming in line with Paris Agreement targets, said a UN report Friday that will underpin key COP28 climate talks.
Emissions have already peaked in developed and a few developing countries, but are continuing to rise in many of the world’s largest economies, according to the UN’s first Global Stocktake of progress in achieving the 2015 Paris treaty’s goals.
