Keeping 1.5°C Alive: Closing the Gap in the 2020s was developed by the Commissioners with the support of the ETC Secretariat, provided by SYSTEMIQ. This briefing paper has also been developed in close consultation with experts from companies, industry initiatives, international organisations, non-governmental organisations and academia. The publication was developed with input from the UK COP26 team to enhance the available analysis in the lead up to COP26. This briefing paper draws heavily on work developed by Climate Action Tracker (CAT) and the International Energy Agency (IEA), and ETC knowledge partners BloombergNEF. We warmly thank our knowledge partners and contributors for their inputs.
