In October 2016, the Kigali Amendment to the Montreal Protocol was adopted in Kigali, Rwanda, committing countries to phase down hydrofluorocarbons (HFCs), potent greenhouse gases used in air conditioning. This marked a major step in climate action.

The Kigali Amendment inspired climate poetry and activist writing, with poets like Kathy Jetñil-Kijiner and Craig Santos Perez addressing the global effort to curb HFCs. It became a symbol of international environmental cooperation.
