Anaergia's Rhode Island Bioenergy Facility has become the first U.S. based RNG plant to receive a negative carbon intensity score from Canada's Ministry of Environment and Climate Change. This designation allows the facility to generate credits under Canada's Clean Fuel Regulations. The facility uses anaerobic digestion to process over 100,000 tons of organic waste annually. By capturing methane that would otherwise escape from landfills, the plant prevents approximately 40,000 metric tons of CO2 equivalent emissions each year.

Interesting to see a US plant tapping into Canadian CFR credits. It shows how these regulatory markets can overlap if the carbon accounting is rigorous enough.

The negative score hinges on the baseline of what would have happened at the landfill. The real question is how the Ministry handles the additionality of these credits over the long term.

The 40,000 ton figure is a good start, but I want to see the actual throughput efficiency and the energy cost of the digestion process itself. Does the net energy gain justify the infrastructure?

Maintenance on these large digesters is usually the silent killer. If they can keep the organic feedstock consistent without huge op-ex spikes, it works.
