Climate Pragmatism in Rwanda
No-Regrets Pollution Reduction on Display in Kigali Deal
Eariler this month, the 28th Meeting of the Parties, an international negotiation among 170 countries around the world, convened in Rwanda to make a deal on phasing out hydroflurocarbons, or HFCs. HFC describes a set of compounds that are commonly used in refrigerants and air conditioners and, thus, are rapidly proliferating around the world. A replacement for chlorofluorocarbons (CFCs) that the 1989 Montreal Protocol began to phase out, HFCs have an outsized impact on global warming--between 100 and 10,000 times worse per molecule than CO2, depending on the exact compound and time frame.
