This past Saturday morning in Rwanda, a landmark deal was agreed upon that will limit emissions of key climate change-causing pollutants found in air conditions. The deal will phase down the use and production of hydrofluorocarbons, known as HFCs, for use in air conditioners. HFCs are thousands of times more potent than carbon dioxide on a pound-per-pound basis, making them an obvious target for international efforts to combat climate change. Scientists say that successfully abandoning HFCs could on its own prevent a 0.5°C rise in temperature by 2100.
More than 190 countries agree on deal to limit global warming from air conditioners
