Environmental Markets and Biogas
1. Carbon Markets
2. Low Carbon Fuel Standard Credits
3. Renewable Identification Numbers (RINs)
Environmental Markets for Biogas
Market Credit Biogas Use GeographicLimitation
California Cap-and-Trade
Offset Any Anywhere in the US
CaliforniaLow Carbon Fuel Standard
LCFS Credit Transportation fuel
Fuel consumed in California
US RenewableFuel Standard
RIN (Renewable Identification Number)
Transportation fuel
Anywhere in the US
California Carbon Market Key Insights
• Buyers = Large emitters in California
• Offset Project Types:
– Livestock manure
– (Post-consumer food waste = voluntary, not yet accepted by California)
• Sunset: 2020

California Carbon Offset ($/mtCO2e)
$/mtCO2e $/cow $/DGE*
Current $8.60 $30.10 $0.21
*Assumes each cow produces 51,072 BTUs/day
Low Carbon Fuel Standard Key Insights
• Biogas must be consumed as transportation fuel in California
– Out of state: “Physical Pathway”
• Buyer = Transportation fuel refiners and importers in California
• Sunset: 2020
– (2020 target applies until legislation is modified)

Cellulosic Biofuel
• Biogas Cellulosic RIN
– Separated Mixed Solid Waste Digester
– Wastewater Treatment Facility Digesters
– Agricultural Digesters
• Cellulosic RIN Price (“D3 RIN”)
Proxy for D3 RIN Price =

Financing
• Revenues are not bankable
– Solution: Price floor
– Solution: Green Credit Reserve
• State policy: Payment for performance > grant making
– Leverage accounting
– Catalyze private capital through government programs based on accounting at this early stage
Increasing Importance of Methane
• LCFS/Offsets = Carbon Dioxide Equivalent
• 1997 Methane Global Warming Potential:
– 21 carbon dioxide equivalent per unit of methane
• 2014 Methane Global Warming Potential:
– 34 carbon dioxide equivalent per unit of methane
