"Two themes run across global climate change governance: different interpretations of how to differentiate between countries’ responsibilities for emissions reductions and the quest for universal participation."

Countries aim to hold global average temperature rise well below 2°C and, if possible, 1.5°C, in line with recommendations from scientists. To meet this target, the UN Environment Programme estimates emissions need to fall between a fourth to less than half of current levels over the next decade (UNEP, 2019). However, their collective emission reduction pledges are far from sufficient. What efforts and disputes have led the planet to this crisis?
