Green Origin (绿色起源) is a global industry intelligence platform dedicated to natural refrigerants — carbon dioxide (CO₂/R744), propane (R290) and ammonia (R717). We track policy and regulation, technology innovation and market dynamics across six continents, serving professionals in refrigeration, heat pumps, air conditioning and cold chain logistics.
Our coverage spans the HFC phase-down under the Kigali Amendment and the EU F-Gas Regulation, the US AIM Act, the rise of heat pumps for heating and hot water, CO₂ transcritical systems in commercial refrigeration, and industrial applications of ammonia and CO₂.
