Indoor-Grown Cannabis Boosting Greenhouse Gas Emission
Namely, to maintain the required environmental conditions for a plant to grow, a considerable amount of electricity has to be used — in other words, lights, air conditioners, and heaters; not to mention that some growers also pump in carbon dioxide to enhance plant growth.
Yet, all of this only makes up for around 11% to 25% of greenhouse gas emissions of a facility — most of the emissions come from pumping fresh air into the facility.
Moreover, not all areas are affected the same. Milder climates mean less heating and air conditioning — hence why indoor cannabis growers in the Pacific and Atlantic coasts emit fewer greenhouse gases than in the Midwest and Alaska, for instance.
Specifically, the lowest emissions are registered in Southern California, while O’ahu in Hawaii has seen the highest emissions.
Furthermore, in Colorado, for instance, the cannabis industry accounts for 1.3% of the state’s total greenhouse gas emissions per year (which is not too far from what coal mining and trash produce), but neither legislators nor consumers seem to be aware of this.
The cannabis industry is a relatively new field, which is why it remains largely unregulated. For instance, not all growers use the latest cannabis growing methods; some use old, energy-consuming instruments and equipment that emit more gasses, while in traditional gardening it is much easier to get hold of the latest equipment.
This is why research is so important — new findings often lead to new discoveries and breakthroughs that help decrease harmful gas emissions and improve the environment. Additionally, without this research, the new legislation would not be drafted to counter the harmful effects of these greenhouse gasses.
