Cannabis and Climate Action - Industry's Role in Sustainability Cannabis https://westcoastbud.io/ may only be an emerging industry, yet its energy use is already making headlines. And that goes far beyond just using electricity to power grow lights, HVAC units and cultivator control solutions. Indoor grows are responsible for emissions equivalent to that produced by three million cars; to curb this impact, operators should first conduct an energy audit on their facilities. 1. Energy Efficiency Cannabis cultivation consumes considerable energy, straining electric utilities and creating an environmental footprint for the industry. Anticipating future regulations, cultivators can take steps to become more energy-efficient - cutting operational costs while moving closer toward carbon neutrality. Indoor growing, which requires dehumidifiers and air conditioning, accounts for the greatest greenhouse gas emissions, but outdoor cultivation still produces high levels of CO2. Switching to greenhouses without grow lights would significantly reduce these emissions. Cannabis grows emit terpenes, natural volatile organic compounds with pleasant scents and tastes that react with sunlight to produce ground-level ozone or nitrogen oxides. Fertilizing with chemical nitrogen compounds only compounds this problem by leading to wet/dry deposition of ammonia that contributes to soil acidification and water eutrophication (Balasubramanian & Galloway 2003). Cultivators can lower emissions by opting for organic fertilizers instead of overfertilization (Balasubramanian & Galloway 2003). Cultivators can reduce emissions by using organic fertilizers instead of chemical nitrogen fertilizers (Balasubramanian & Galloway 2003). 2. Water Conservation As well as increasing energy efficiency, cannabis growers can also decrease their carbon footprint by limiting water usage. While the exact amount may depend on factors like plant type, climate and cultivation practices - best practices include crop rotation and restricting irrigation. Cannabis producers can reduce their carbon footprint through water conservation as well as by employing local energy sources like solar, wind or nuclear. By cutting waste production, switching to green packaging solutions and investing in forest management projects, the cannabis industry can also contribute to reduced greenhouse gas emissions and greenhouse gas emissions. Indoor cannabis cultivation produces greenhouse gas emissions due to energy requirements for lighting and ventilation systems, whereas growing outdoors helps decrease their carbon footprint; however, outdoor cultivation does require additional equipment and expertise. If carbon emissions occur due to indoor cultivation then purchasing credits from established emission-offset projects may help offset them; as cannabis becomes a mainstream market investors will increasingly demand ESG disclosures and responsible investment policies from publically reporting companies; leading them to dedicate greater focus towards sustainability by publicly reporting companies. 3. Recycling Cannabis and hemp farmers generate substantial waste, such as plant clippings and soil contamination. While much of it can be recycled or used as fertilizer, shipping this waste to composting sites requires time and resources. Furthermore, companies shipping across state lines must adhere to stringent regulations regarding compliance. Wang et al conducted research that revealed how cannabis cultivation produces biogenic volatile organic compounds (BVOCs) which contribute to ozone formation and particulate matter concentrations, as well as to degraded water quality in nearby watersheds. Soil erosion is another significant issue associated with cannabis cultivation, contributing to fine sediment loads that pollute streams and threaten rare and endangered species (Carah et al). Furthermore, surface water diversions for irrigation increase pressure on an already limited source of freshwater resources. Cannabis production can be done sustainably. By moving indoor operations to greenhouses, using less electricity, and decreasing transportation emissions, we can significantly lower its carbon footprint. 4. Climate Change Mitigation Cannabis plants thrive in warm environments, yet climate change threatens their environments of choice. Higher temperatures can increase pest pressure and decrease air quality while droughts deprive plant roots of needed moisture. Cultivation practices also contribute to soil erosion. Fields cultivated on slopes typically experience rapid soil loss; land-terracing and forest clearing exacerbate this problem, leading to fine-sediment loading into streams which threaten rare and endangered species (Carah et al. 2015; Barringer 2013).
