2008 Zürich Hydrofluorocarbons Treaty (A better world TL)

==The Chemicals involved==
Hydrofluorocarbons (HFCs), organic compounds that contain fluorine and hydrogen atoms, are the most common type of organofluorine compounds. They are commonly used in air conditioning and as refrigerants [1] in place of the older chlorofluorocarbons such as R-12 and hydrochlorofluorocarbons such as R-21. They do not harm the ozone layer as much as the compounds they replace; however, they do contribute to global warming. Their atmospheric concentrations and contribution to anthropogenic greenhouse gas emissions are rapidly increasing, causing international concern about their radiative forcing.
Fluorocarbons with few C–F bonds behave similarly to the parent hydrocarbons, but their reactivity can be altered significantly. For example, both uracil and 5-fluorouracil are colourless, high-melting crystalline solids, but the latter is a potent anti-cancer drug. The use of the C-F bond in pharmaceuticals is predicated on this altered reactivity. Several drugs and agrochemicals contain only one fluorine center or one trifluoromethyl group.
The 2008 UN Zürich Hydrofluorocarbons Treaty outlawed them, due to these chemicals' contribution to climate change.
==The treaty==
Japan, Switzerland, Sweden and Norway were the first to ban Hydrofluorocarbons in 2002 over a theoretical threat to the world caused by it's addition to global warming.
These nations persuaded the world it to taking the safer option in 2008 by signing the Zürich Hydrofluorocarbons Treaty, which forbade thire use, storage and production after 5 years. Norway chaired the summit and the issue of melting polar ice shelves has lessened significantly since 2016.
