Volatile Organic Compound (VOC) Emissions from Cultivation and Extraction Terpenes = VOC Emissions = Odor Solvents = VOC Emissions (potential non-compliance)

Ozone
VOC chemically react with NOx in the presence of sunlight to form ground-level ozone.*Terpenes (odor)
Nitrogen Oxides (NOx)
Elevated ozone can cause:• Stinging eyes and throat• Chest pain• Coughing• Breathing difficulty• Cardiovascular harm• Environmental impacts
Breathing ozone has negative health affects on the lungs and heart and is harmful to the environment. O

Colorado’s ozone nonattainment area
Over 50% of Colorado’s marijuana facilities fall within the ozone nonattainment area.
VOC emissions from cannabis cultivation are NOT subject to state air quality regulations
• Marijuana cultivation is considered an “agricultural activity” • Even when it is grown indoors
• Agricultural activities are exempt (for the most part) from state air quality regulations
• CRS 25-7- 109(8)(a)
CDPHE Air Quality Sampling Study: $31,000
Air quality sampling at four cannabis cultivation facilities• Air Samples collected:
• Clone, veg., flower rooms• Harvesting and trimming activities• Pre and post filtration at exhaust points
Establishing a VOC emission factor for cannabis cultivation
Volunteers Needed!
Solvents Evaporate VOCs during Extraction and Cleaning
• Common Solvents • Propane • Butane • Ethanol • Isopropyl Alcohol
• Mass Balance for calculating air emissions
• Purchased minus inventory minus waste pick-up
• Assume everything else evaporates

VOC emissions from MIP (extraction) facilities ARE subject to state air quality regulations!• The processing of the plants with solvents to extract
concentrates at MIP facilities is considered a manufacturing process.
• Manufacturing processes are subject to air quality regulations including APEN and permitting requirements based on annual emissions levels.
Most extraction facilities are unaware of these air quality regulations and are currently NOT in compliance!

Odor control BMPs may also control VOC emissions
Odor Controls for Cannabis
Controls VOC and odor
Carbon filtration
Neutralizing agents
Controls odor but not VOC
Masking/ counteractive
agents
Reducing VOC emissions from cannabis cultivation facilities will:
Contribute to reducing ozone concentrations that negatively impact human health and the environment
Help the nonattainment area come into compliance with the ozone standard

Diesel engines at rural cannabis cultivation operations emit NOx
• Complaints about cannabis cultivation operations using diesel generators for electrical power in rural Colorado
• Sole or supplemental power supply
• Emergency back-up

Cannabis Industry Air Impacts
• Volatile Organic Compound (VOC) Emissions• Cultivation of the plants (Terpenes=VOC)
• Evaporating solvents during extraction and winterization processes
• Cleaning solvents evaporating during use• More of a concern in urban areas for ozone formation
• Nitrogen Oxides (NOx) Emissions • Diesel generators/engines for supplying electricity to
indoor and greenhouse cultivation operations• Issue unique to rural areas that are at electrical grid
capacity
www.colorado.gov/cdphe/greencannabis/air-quality
Air Pollution BMPs for Cannabis • Cultivation Facilities
• “Sealing” the grow space and controlling air flow through carbon filters• Venting greenhouses at night • Maintain temperature and humidity within ranges to reduce odors & VOCs• Document operating and maintenance procedures for HVAC system and
carbon filters• Extraction Facilities
• Inspect and maintain all storage devices of solvents and extraction equipment to prevent leaks
• Never dispose of a solvent through direct evaporation or spillage• Maintain an inventory of all solvents & calculate annual air emissions• Robust employee training program

Carbon Basics
Climate Change Potential
CO2 is actually CO2e
25x Methane (CH4)
298x Nitrous Oxide (N20)
PHCs, HFCs, SF6
Carbon Footprinting
Scope 1
Scope 2
Scope 3
www.sustainabis.life
Carbon and Cannabis Basics Indoor growing has an incredibly high carbon impact
For each kilogram of cannabis produced roughly 4,600 kg of CO2 is emitted
Largest impact is scope 2
HVAC ~ 50%
Lighting ~ 35%
1% total electricity usage in US attributed to indoor cannabis growing in 2012
Primarily the electricity is coming from coal and natural gas
Special considerations must be made both for carbon sequestration for cannabis and CO2 injection
www.sustainabis.life
Calculating Carbon Set a Boundary!!
Collect Data within the boundary.
Bills Invoices
Purchase orders
Get creative!
Analyze and aggregate data
Use available conversion rates
Company A uses 2,000 kWh monthly of electricity in their grow operation.
The EPA conversion rate for kWh to CO2 is 740 grams per kWh.
Take the conversion rate and multiply it by the number of kWhs emitted annually.
2000 kWh X 12 months X 744g CO2 = 17,856,000 grams of carbon.
This number can be represented as 17,856 kilograms of CO2 or 17.86 metric tons of CO2
Keep in mind locality.

Carbon Reduction Strategies Start With Efficiency
High efficiency lighting and HVAC systems
Increased insulation in facilities
Heat recapture systems on operational machinery
On-site renewable energy
Electric or natural gas fleet vehicles
Composting and/or recycling
Sourcing carbon neutral ingredients
Carbon neutral, recyclable, or compostable packaging.

Holistic Carbon Footprinting A detailed breakdown of GHG emission
sources, factors and calculation methodologies
Short and long-term emission reduction goals

The Importance of Understanding Carbon Cannabis is an agricultural product
Carbon causes Anthropogenic Climate Change
Calculating Carbon provides a business with a snapshot of current resource usage long term financial risk
Four primary risks:
Changing policy and Regulations
Change to Technology
Physical and Environmental Risks
Changing Consumer Sentiment
Liability Risk
Positions your company as a forward thinking and caring organization
Creates a larger market share and larger brand recognition
90% of customers in emerging markets believe they have a duty to buy environmentally and socially responsible products
It is imperative that the Cannabis Industry establish itself as a conscious and legitimate sector.
