China to tackle HFCs

China has proposed a national plan to deal with hydrofluorocarbons (HFCs). The plan recommends adjusting the existing regulations dealing with Ozone Depleting Substances (ODS) to cover HFCs, and to strengthen monitoring and enforcement of existing measures. It also proposes adding HFCs to existing regulations consistent with implementation of the Kigali Amendment, including a quota system […]


China and Thailand stop illegal R22 shipment

China and Thailand have collaborated using the OzonAction iPIC system to prevent a huge illegal consignment of ozone-depleting and climate-damaging R22 from going ahead.   Created and hosted by the United Nations, the informal Prior Informed Consent (iPIC) system enables countries to share details of eligible importers and exporters with other member countries through a […]

Study on spread of COVID-19 in air conditioned bus

The coronavirus could be transmitted over a longer distance than previously thought, especially within an enclosed air conditioned environment, according to a study by a team of Chinese government epidemiologists. The research by the Hunan-based team throws into question the official guidelines from China’s health authorities on COVID-19 prevention to keep “a safe distance” of […]


Rogue HFC23 emissions on the rise

A new report in Nature Communications has highlighted a large and unexpected increase in emissions of HFC23 – a hydrofluorocarbon with extremely high global warming potential that is mainly produced as an unwanted by-product during the manufacture of R22. R22 is a hydrochorofluorocarbon (HCFC) that destroys the ozone layer, and it is being phased out […]


China denies illegal use of CFC-11

China’s environmental ministry has cast aspersions over claims that the country is responsible for a recent spike in emissions of CFC-11, a banned ozone-destroying gas. A recent report in science journal Nature found that China is responsible for approximately 40–60 per cent of the recent rise in CFC-11 (trichlorofluoromethane) emissions. Researchers traced the increase to the northeastern […]


CFC-11 still being used illegally

Earlier this year, reports emerged of a “mysterious” rise in CFC-11 (trichlorofluoromethane) quantities in the atmosphere. This was surprising, because CFCs had been phased out by the Montreal Protocol due to their harmful effect on the ozone layer, and were thought to be virtually extinct. Now, a new report from the Environmental Investigation Agency (EIA) […]
