AECOM, an Engineering Services company based in the US, reported total carbon emissions of approximately 1.597 billion kg CO2e in 2025. This figure comprises 26.3 million kg CO2e from Scope 1 emissions, 18.6 million kg CO2e from Scope 2 emissions, and about 1.552 billion kg CO2e from Scope 3 emissions.

For 2024, AECOM's total carbon emissions were approximately 1.795 billion kg CO2e, with Scope 1 emissions at 29.1 million kg CO2e, Scope 2 at 22.9 million kg CO2e, and Scope 3 at about 1.743 billion kg CO2e. In 2023, the company's total emissions were approximately 1.802 billion kg CO2e, consisting of 26.6 million kg CO2e from Scope 1, 24.4 million kg CO2e from Scope 2, and about 1.751 billion kg CO2e from Scope 3.

AECOM has set ambitious climate commitments validated by the Science Based Targets initiative (SBTi). The company aims to achieve net-zero greenhouse gas emissions across its value chain by FY2040, using FY2018 as a baseline year. This includes near-term targets to reduce absolute Scope 1 and 2 GHG emissions by 60% by FY2030, and absolute Scope 3 GHG emissions from purchased goods and services, capital goods, and business travel by 50% by FY2030. Long-term targets aim for a 90% reduction in absolute Scope 1 and 2 GHG emissions and a 90% reduction in absolute Scope 3 GHG emissions (from purchased goods and services, capital goods, and business travel) by FY2040, both against a FY2018 baseline.

AECOM is also a signatory of The Climate Pledge, committing to reach net-zero carbon emissions by 2040.
