Nutrient Management Carbon Credits
Methane Avoidance Carbon Credits
Avoided Methane Carbon Credit Projects that digest eligible feedstocks and combust biogas can
earn carbon credits for avoided methane. Eligible feedstocks:
1) Livestock manure, 2)Post-consumer food waste, 3)Agro-Industrial waste previously managed in an anaerobic lagoon.
Avoided Methane Carbon Credit 2,500 cow digester
generates ~3.5 credits per cow per year or 8,750 credits per year
Carbon price Voluntary $4.00
Pre-Compliance$8.50

Renewable Energy Certi!cates (RECs)
Renewable Energy Certi!cates
Projects that generate electricity can sell RECs.
Barrier: Washington Renewable Portfolio Standard does not allow RECs from projects that also sell
carbon credits.
Trends Rapid increase in natural gas supply is causing natural gas
and therefore electricity prices to fall.
Biogas to Transportation Fuel
Renewable Identi!cation
Number
Projects that clean and compress biogas into transportation fuel can earn Renewable Identi"cation
Numbers.

RINs are owned and sold by the entity that compresses the gas and fuels the vehicles.

Nutrient Management
• 1% of applied nitrogen is released as N2O • N2O is a potent greenhouse gas – 298 times the global warming potential of CO2
• Removing nitrogen can earn carbon credits
$ Nutrient
Management Carbon Credits
Nutrient Management • Nutrient recovery that includes ammonia stripping
can capture half of the nitrogen in manure before it is applied to "elds – Before recovery: 8 lbs N/1,000 lbs of manure – With recovery: 4 lbs N/1,000 lbs of manure
• 5,000 cow dry lotà 1,280 metric tons of nitrogen not applied to nearby "elds – Simpli"ed Tier 1 Linear Emissions Factor à – 8,800 metric tons carbon dioxide equivalent reduction
