Germany launches pledge to cut emissions of potent greenhouse gas
Germany has launched an international pledge to cut emissions of sulfur hexafluoride, known as SF6, from the electric power sector.
The synthetic gas is used to insulate high-voltage electrical equipment, and it traps 24,300 times more heat than carbon dioxide pound for pound.
SF6 can stay in the atmosphere for 1,000 years, but it has received relatively little attention from policymakers.
China produces more than half of global SF6 emissions, while its electricity grid is expanding rapidly.
The pledge asks signatories to improve emissions monitoring and reporting and support cuts through recycling, leak prevention or alternative insulating technologies.
The European Union and United Kingdom are its first endorsers, and the pledge is due to launch at a UN climate conference in Turkey this month.
China has called for stronger international climate cooperation but has not said whether it will sign.
Germany has launched an international pledge urging countries to monitor, report and reduce emissions of sulfur hexafluoride, or SF6.
The synthetic gas is used as an insulator in high-voltage electrical equipment and is 24,300 times more effective at warming the atmosphere than carbon dioxide, pound for pound.
The pledge was announced at a United Nations Environment Program meeting in Kigali, Rwanda, and is set to officially launch at the UN climate conference in Antalya, Turkey.
The European Union and the United Kingdom are the first to endorse the pledge.
More than half of global SF6 emissions come from China, according to the article.
- Who
- The German government launched the initiative. The European Union and the United Kingdom are the first to endorse it.
- What
- The Global SF6 Pledge urges countries to strengthen monitoring and reporting of SF6 emissions and support efforts to reduce releases.
- When
- It was announced this week, according to the article published November 6, 2026. Its official launch is planned for this month.
- Where
- It was announced at a United Nations Environment Program meeting in Kigali, Rwanda. Its official launch is planned for the UN climate conference in Antalya, Turkey.
- Why
- SF6 is an exceptionally potent greenhouse gas that has received relatively little attention from policymakers.
This story does not have two clearly opposing sides.
The United Nations identified SF6 as one of six key greenhouse gases.
China’s National Climate Change Response Plan called for an SF6 management plan to reduce emissions.
Germany announced the Global SF6 Pledge at a United Nations Environment Program meeting in Kigali, Rwanda.
The pledge is due to officially launch at the United Nations’ global climate conference in Antalya, Turkey.

What people are saying
It’s a gap
The pledge finally turns the spotlight on SF6, but until the world’s largest grid builder matches that ambition, we’re only treating half the leak
China will continue to work with all countries to strengthen international cooperation on climate change, contributing to a green transition and the sustainable development of humanity
