Air conditioners and the 40-year treaty trying to limit their climate harm
Original: Air conditioners contribute to climate change—this 40‑year‑old treaty aims to limit the harm
Air conditioning is a growing source of climate-warming emissions, both through high electricity demand and refrigerant gases. A treaty now four decades old, the Montreal Protocol, is being pointed to as the key tool for limiting that harm, including later amendments that phase down hydrofluorocarbons used in cooling systems worldwide.
Why now: Rising global temperatures are driving record demand for air conditioning, renewing attention on how cooling itself worsens climate change.
