Information about Guernsey's Greenhouse Gas Emissions can be found on this page.
Guernsey signed up to the Kyoto Protocol and UN Convention on Climate Change in 2002. Since then, greenhouse gas emissions inventories have been calculated in a consistent manner across all jurisdictions to ensure comparability and avoid double counting or omissions.
The Guernsey emissions inventory is compiled by Aether, the company which calculates emissions for UK Overseas Territories and Crown Dependencies on behalf of the Department for Business, Energy & Industrial Strategy. The inventory is updated annually and the latest data is presented in the Greenhouse Gas Bulletin.
A major emissions contributor is power generation. In late 2018 and throughout much of 2019 there were issues with the cable link to France, so more power had to be generated on island, leading to higher emissions. This cable was replaced in October 2019.
