Category 3 is an extension of your Scope 1 and 2 emissions—it captures the upstream emissions from producing the fuels and energy you consume. Examples include extraction and refining of fuels, and transmission losses in electricity grids. For simplicity, Selko calculates these emissions based on your Scope 1 and 2 data using well-to-tank (WTT) and transmission loss factors.
