According to a new study by the Potsdam Institute for Climate Impact Research (PIK), 30 percent of regions worldwide have managed to reduce their CO2 emissions while their economies have grown. The trend is intensifying, which is „important progress“, the PIK announced – but progress is not fast enough to achieve the goals of the Paris Climate Agreement. For their study, the researchers examined data from 1,500 regions from the past 30 years, for example from Chinese provinces, US states and German federal states. The regions examined were responsible for 85 percent of global CO2 emissions.
