Little-noticed treaty could help delay climate catastrophe

2016 Kigali amendment on hydrofluorocarbons could reduce warming by a small but crucial 0.5C

From the beginning of next year, a new global pact will take effect that could have a profound impact on climate change, cutting harmful greenhouse gas emissions by amounts that could help stave off some of the worst impacts predicted by the IPCC.

This little-noticed treaty has nothing to do with the Paris accord, the United Nations Framework Convention on Climate Change (UNFCCC) negotiations that have dragged on since 1992, or energy sector emissions, which have resumed their rise.
