Climate change justice: sharing the burden
Pages 14

Climate science tells us that any further increase in global temperature must be limited to 2 degrees Celsius. Past this point, global warming becomes irreversible. To stay within the 2 degrees limit, the world must collectively reduce global CO2 emissions by 50-80 percent of 2000 levels by 2050. Encouragingly, there is a growing global consensus on this. The United Nations Convention on Climate Change, drafted in 1992 at the United Nations Conference on Development and Environment (Rio Summit), and signed by 197 parties to date, acknowledges the global responsibility to address anthropogenic climate change. The 2015 Paris Agreement further affirms the commitment to the 2 degrees target.
