Saturday, October 15 in Kigali, Rwanda, 197 countries signed a landmark agreement on the reduction of hydrofluorocarbons (HFCs), powerful greenhouse gases used in air conditioning systems, in the freezer and in cans that contain foam substances. Drastically reducing their emissions, it could avoid
a temperature rise of between 0,2 and 0,44 ° C by the end of the century.
.from SKILLET GRILLED. HFCS had replaced the banned chlorofluorocarbons under the Montreal Protocol of 1987, because managers ozone depletion. HFCs do not seem to contribute to the ozone hole, but over the years became one of the most potent greenhouse gases (substances of this type are responsible for 8% of human impact on climate change).
THE RESOLUTION. The agreement - in the form of a series of additions to the Montreal Protocol - requires industrialized countries start gradually to put (it will start from a 10% cut) a roof to these substances in 2019, and that those developing they can instead do it by 2024, receiving aid for the transition to other substances, less polluting but also less economical.
By 2047, you should get to a 85% cut of HFC, a small but important step to respect the agreements on the Paris climate.
