The video discusses a summit in Kigali where representatives from nearly 200 countries aim to reach an agreement to reduce greenhouse gas emissions, specifically hydrofluorocarbons (HFCs). These gases, used in refrigeration and aerosols, significantly contribute to global warming. The goal is to align with the Paris Agreement to keep global temperature rise below two degrees Celsius. The video also covers the history of HFCs, introduced in the 1990s to protect the ozone layer, but later found to be more harmful than CO2 in trapping heat.
