AECOM, a leading engineering services firm headquartered in the US, has reported its carbon emissions and set ambitious climate commitments. In 2025, the company's total greenhouse gas emissions were approximately 1.6 billion kg CO2e. This figure comprised roughly 26.3 million kg CO2e from Scope 1 (direct emissions), 18.6 million kg CO2e from Scope 2 (indirect emissions from purchased electricity and heat), and a substantial 1.55 billion kg CO2e from Scope 3 (all other indirect emissions). The primary contributor to Scope 3 emissions in 2025 was purchased goods and services, accounting for approximately 1.48 billion kg CO2e.

AECOM is committed to significant emissions reductions, with a Science Based Targets initiative (SBTi) validated goal to achieve net-zero greenhouse gas emissions across its value chain by 2030, using a 2018 baseline. Near-term targets include a 60% reduction in Scope 1 and 2 emissions and a 50% reduction in specific Scope 3 categories (purchased goods and services, capital goods, and business travel) by 2030, compared to the 2018 baseline. The company also aims for a 90% reduction in all scopes by 2040, from the same 2018 baseline, aligning with net-zero commitments. AECOM has also set a long-term goal to achieve net-zero carbon emissions by 2040.
