A study, published by Nature Sustainability earlier this year, has found that indoor-grown Cannabis has lifecycle greenhouse gas emissions ranging from 2,283 to 5,184 kg CO2-equivalent per kg of dried flower (2.3-5.2 kg CO2-equivalent per gram of dried flower). ![Exploding head :exploding_head: 🤯](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f92f.png)
Emissions associated with growing 1 ounce of cannabis indoors is equivalent with burning 7-16 gallons of gasoline, depending on where in the US it's grown:

In contrast, sun-grown Cannabis is typically carbon neutral or even carbon negative.
We need to bring the crop into the sun.

The life cycle GHG emissions are largely attributed to electricity production and natural gas consumption from indoor environmental controls, high-intensity grow lights and the supply of carbon dioxide for accelerated plant growth.
