Increase in HFC-23 emissions linked to China, India: Study

The University of Bristol found that HFC 23 emissions have risen despite claims from China and India of halted emissions. The study, part of the Montreal Protocol, expected a 90% decline in emissions. Data from 2015 to 2018 linked emissions to China and India, contradicting their reports. HFC 23 is a potent greenhouse gas, with one ton equating to over 12,000 tons of CO2. It is commonly used in cooling systems like refrigerators and air conditioners.
