Cannabis Growth is harming the environment with a very high carbon footprint

The energy and materials required to grow cannabis indoors was studied and quantified the corresponding greenhouse gas emissions. The analysis was performed across the United States and accounted for geographic variations in meteorological and electric grid emission data. Greenhouse gas emissions for legal cannabis ranges from 2,283 – 5,185 kg CO2-equivalent per kilogram of dried flower. Using the EPA calculator, this is equivalent to 583 gallons of gasoline consumed. This study was published in the journal Nature Sustainability.
