“Keeping a global, 21st century temperature rise under 2 degrees Celsius will require urgent action on a group of chemicals increasingly being used in products such as air conditioners, refrigerators, firefighting equipment and insulation foams.”

According to this new UNEP report, there is an urgent need to tackle the hydrofluorocarbons (HFCs),  which are being used as replacements for the chemicals that are affecting the ozone layer.

The report says that “by 2050 HFCs could be responsible for emissions equivalent to 3.5 to 8.8 Gigatonnes (Gt) of carbon dioxide (Gt CO2eq) – comparable to total current annual emissions from transport, estimated at around 6-7 Gt annually.”
