Tobacco production causes over 80 million tons of carbon dioxide emissions annually. A single cigarette can be responsible for up to 14 grams of CO2 equivalent throughout its lifecycle. Manufacturing and distribution generate emissions equivalent to roughly three million transatlantic flights. The industry cuts down 600 million trees yearly (one tree produces about 15 packs of cigarettes). Since the 1970s, an estimated 1.5 billion hectares of forests lost has caused up to 20% of annual greenhouse gas emissions.
