WA Greenhouse Gas Assessment Guidelines (2019)

Policy Description

Western Australia’s Environmental Protection Authority (EPA) published its greenhouse gas assessment guidance in March 2019 to guide environmental assessments for new or expanded projects with direct scope 1 emissions of more than 100,000 tonnes CO2 equivalent per year. Under the Guidance, the EPA could request credible estimates of scope 1, 2 and 3 emissions over the life of the proposal as well as measures to avoid, reduce and offset emissions. Proponents of these projects were required to offset any Scope 1 or 2 residual (net) emissions associated with the proposal. Proponents were not required to offset Scope 3 emissions.
