Evidence supports urgent action to halve emissions by 2030

Ecological catastrophy - Immediate and deep emissions reductions are required across all sectors - as well as widespread use of carbon removal technology - to limit warming to 1.5°C, according to a new Intergovernmental Panel on Climate Change (IPCC) report, involving contributions from UCL academics. Released today, the report assesses the literature on the scientific, technological, environmental, economic and social aspects of climate change mitigation. The report found that limiting global warming will require major transitions in the energy sector, including a substantial reduction in fossil fuel use, widespread electrification, improved energy efficiency, and use of alternative fuels, such as hydrogen.
