The United Nations Environmental Programme (UNEP) has just published an updated version of its annual Emissions Gap Report. This report studies how large the expected emission gap in 2030 will be between the current Nationally Determined Contributions (NDCs) and those that would be required to limit global warming to 1.5°C (or 2°C). The news is not good. The current commitments of governments around the world will lead to an expected temperature rise of 3.2°C by the end of this century. In order to be able to limit climate change to a maximum of 1.5°C, a level that is believed to be associated with controllable climate damages (IPCC 2019), annual carbon emissions must drop significantly by 2030.
