A new deal struck between the Montreal Protocol and China will see the country aim to eliminate its production of HCFCs, ozone-depleting substances that are also potent greenhouse gases.
The initiative aims to prevent eight billion tonnes of carbon dioxide equivalent emissions.
The decision, reached at the most recent meeting of the Multilateral Fund, is a step in the accelerated phase-out of HCFCs.
HCFCs are chemicals used mainly in air conditioning, refrigeration and solvents. They are also used as feedstock for other products such as Teflon feedstock use of HCFCs is not regulated by the Montreal Protocol as it is deemed that the HCFCs are entirely consumed in the process and not emitted to the atmosphere. However, the production of HCFC also results in the unwanted production of HFC-23, a super greenhouse gas.
EIA is calling on China to formally pledge to destroy the HFC-23 from all Chinese HCFC production facilities, including facilities which produce HCFC for feedstock.
