Sustainability In The Cannabis Industry Statistics 2026

Indoor cannabis cultivation can emit about 9.6 kg CO2e per kg of dried product, while outdoor grows come in closer to 2.0 kg CO2e, a gap large enough to reshape how we judge “sustainable” choices. At the same time, U.S. data centers alone were estimated to account for 2.3% of retail electricity consumption in 2023, placing energy demand front and center for any electricity hungry operation. From electricity intensity and waste diversion to pesticide, water, and investment signals, these sustainability statistics help explain why cannabis climate impact is anything but one dimensional.
