Date: 18.11.2025
Time: 15:00 (BRT)
Location: UNFCCC Pavilion Side Event Room 2

Ukraine will hold a high-level event on the sidelines of COP30 to present new findings on the climate impact of Russia’s full-scale invasion of Ukraine. The session will outline how military operations, large-scale destruction, extensive fuel burning, landscape fires, and other war-related processes have generated significant greenhouse gas emissions that will have long-term consequences for global climate efforts.

The event will present new scientific data quantifying these emissions, and will explain how the environmental cost of the war affects not only Ukraine, but also the wider region and the global climate system. It will also address the relevance of these findings to Ukraine’s approach to green recovery, international climate cooperation and future policy planning.
