So if you divert organics from a landfill to composting, you reduce GHG emissions and... you may be able to generate and sell Carbon Credits (tons of CO 2 e) economically.
Several Registries and Protocols to Choose From others
Some are flexible and project specific; others are not.
All require this. Eligible projects must be: 1.Voluntary 2.Real 3.Additional 4.Verifiable
CAR What composting is eligible? Only food waste and food-soiled non- recyclable paper Only commercial and residential food waste Non-industrial (no agricultural or food processing)
CAR What composting is eligible? Not other organics like green waste or biosolids diverted from landfills (like CCX) Not financial additionality (like VCS) Not project expansions (like VCS)
CAR Eligibility Start Date – Submit <6 months before start date Location – U.S., territories & tribal areas Performance Standard Eligible feed stocks (MSW food waste, soiled paper, grocery store waste if diverted from LF or new) BMP (time, temperature, turning)
CAR Eligibility Legal Requirement Test (Voluntary) Regulatory Compliance Test
Quantifying Emissions “Baseline Emissions” = what would have been emitted if the organics were landfilled Assumed to decrease over time as more of the landfill is covered and more CH 4 is recovered
Quantifying Emissions Baseline GHG Emissions - Composting GHG Emissions GHG Reduction* * In tons CO 2 equivalents
Calculation must consider all sources, sinks and reservoirs. Source – releases GHG to atmosphere Sink – removes GHG from atmosphere Reservoir – stores or accumulates GHG
CAR uses standard, default calculations for: Landfill GHG generation and emissions, & Compost GHG generation and emissions. And, CAR requires that the eligible (food waste) portion of the feedstock be measured.
Conclusions 1.Composting food waste and other organics could be a source of C-Credits. 2.C-Credits could be of significant value and improve economic viability. 3.There are several registries and protocols to consider. 4.Each project should consider the benefits and costs of each before proceeding.
