The US, Canada, and Mexico have submitted a proposal to strengthen climate protection under the Montreal Protocol— the international treaty that phases out the production of a number of substances responsible for ozone depletion. The proposal targets the production and use of HFCs, a group of “super” greenhouse gases. Source: IGSD.
