A United Nations Environment Programme Report [1] published on 26 November 2019 says that, even if all current unconditional commitments under the Paris Agreement are implemented, the world is nevertheless heading for a 3.2°C temperature rise.

The Intergovernmental Panel on Climate Change (IPCC) has warned that going beyond 1.5°C will increase the frequency and intensity of climate impacts. In order to meet the Paris target of a 1.5°C, global emissions must be cut by 7.6% every year for the next 10 years.

The report states that technologies and policy knowledge already exist to cut emissions, but transformations must begin now. G20 [2] nations account for 78 per cent of all emissions, but 15 G20 members have not committed to a timeline for net-zero emissions
