Fuels in scope 3

Greenhouse Gas Protocol

Companies should use life cycle emission factors to calculate scope 3 emissions related to fuels and energy consumed in the reporting company’s value chain, except for category 3 (fuel- and energy-related activities not included in scope 1 or scope 2). Compared to combustion emission factors, life cycle emission factors represent all emissions in the upstream supply chain of fuels and energy. Where possible, companies should use life cycle emission factors that are as specific as possible to the type and source of fuel consumed (e.g., specific to the technology used to produce a fuel).

Implementation by Carbon+Alt+Delete

Currently, Carbon+Alt+Delete relies on the EF provider to embed life-cycle emission in the supplied factors; and has not integrated life-cycle factor support.

In an upcoming update, the difference between combustion and Life cycle emission factors will be made explicit and this each will be applied in their corresponding scope regardless of EF provider definition. (combustion EF: scope 1+2, life cycle EF: scope 3)
