Hi Kim, thanks for your question. It’s not easy! Each project may have a different model for the calculation depending on the work involved. However, in general, we leverage historical customer ordering patterns, material consumption data and forecasts when available to estimate total annual material removed (ex. corrugated, plastic, etc). We then leverage GaBi Software to create “CO2 equivalent” emissions values for that removed material. There are additional transportation emissions benefits achieved from the reduced freight weight that we are not currently including, but hope to in the future.
