Question to the Department for Environment, Food and Rural Affairs:

To ask His Majesty's Government what assessment they have made of the extent to which the release of trifluoromethane (HFC-23) from manufacturing and other processes within the UK is being prevented in line with the 2016 Kigali Amendment to the Montreal Protocol; and what steps they are taking internationally to support and move towards such measures being taken around the world.

HFC-23 emissions in the UK are reported annually in the National Greenhouse Gas Emissions Inventory submitted to the UNFCCC and have been assessed to be insignificant (~0.0MtCO₂e) for all reported years since 2010. Since 2012, HFC-23 emissions have represented less than 0.1% of the UK’s territorial HFC emissions.

As a donor country to the Montreal Protocol’s Multilateral Fund, the UK provides financial support for developing countries to comply with their Kigali Amendment obligations, including those regarding HFC-23.
