There are two aspects that constitute Scope 3.3:
Well to Tank: The upstream emissions associated with the extraction, refining and transportation of fuel.
Combustion: Emissions from the burning of fuel which releases gases into the atmosphere.
The KEY ESG app automatically calculates your Scope 3.3 based on the data you entered in Scopes 1 & 2.
Scope 3.3 Methodology in the KEY ESG Platform:
For electric vehicles, both market-based and location-based values currently use location-based rates.
This is due to the absence of user-provided renewable energy input.
Market-based Scope 3.3 emissions may be less accurate for EV-heavy users.
We will review making these numbers more accurate by adding market-based calculations in the future.
