Calculating GasIDs

As discussed before, to define a GasID the weight (w) or total avoided emissions of GHGs (AE) must be calculated. Again, the equation for this is as follows:

To understand this process let’s explore an example of calculating a GasID for a glass TRC originated in San Francisco, California municipality #1.

For more information on the equation of a TRC see Minting TRCs

For more information on the equation of a MassID see MassID Composition

Zero Waste Auditors will work with the recycling entities in order to provide accurate CO2e baselines based on the type of material and location. These formulas are known by corporations from their supply chain cost calculations which auditors can then apply to the creation of GasIDs from TRCs of plastics, paper, glass, and more based on the unique impact of recycling these materials in each location. From this, we know the baseline emissions (BE).

Now, the avoided emissions (AE) can be calculated as follows:

GasIDs can be calculated in the same fashion for just about every other waste type (Plastic, Cardboard, Paper, Aluminum, etc.) at each recycling facility, using tools like the EPA’s WARM Model.. By measuring carbon emissions from supply chains and valuing the climate benefits that recycling brings to a circular economy, the Carrot Fndn will be able to incentivize recycling and eliminate tremendous amounts of waste and carbon emissions. Each Ton of recycled waste will be able to be tracked and GasID calculations will be available to all for transparency and continuous improvement.
