A briefing to the 41st Open-Ended Working Group of the Parties to the Montreal Protocol, July 2019, Bangkok
The global phase-down of hydrofluorocarbons (HFCs), starting in January 2019 under the Kigali Amendment to the Montreal Protocol, could avoid 0.5°C of warming by 2100. By simultaneously improving the energy efficiency of cooling systems, this climate benefit could potentially be doubled
The Special Report on Global Warming of 1.5°C. Written by 91 authors from 40 countries, with 133 contributing authors and 1,113 reviewers, is a “final call” on global warming, urging ‘rapid, far-reaching and unprecedented changes in all aspects of society’ in order to stay below 1.5°C
To celebrate World Ozone Day, our Climate Campaigner, Sophie Geoghegan, discusses the success of the Montreal Protocol in protecting the ozone layer by phasing out ozone-depleting substances (ODS) as well as remaining challenges including shifting to climate-friendly cooling and phasing down production of HFC
A report has been published on the possibility of the 'Hothouse Earth' scenario, in which man-made climate change may result in irreversible tipping points and catastrophic environmental change. Collective action is required to prevent this including hydrofluorocarbon (HFC) management under the Kigali amendment.
