AECOM, an Engineering Services company headquartered in the US, reported total emissions of approximately 1.6 billion kg CO2e in 2025. This included about 26.3 million kg CO2e from Scope 1 emissions, around 18.6 million kg CO2e from Scope 2 emissions, and approximately 1.55 billion kg CO2e from Scope 3 emissions. In the prior year, 2024, their total emissions were about 1.8 billion kg CO2e, with Scope 1 at roughly 29.1 million kg CO2e, Scope 2 at around 22.9 million kg CO2e, and Scope 3 at approximately 1.74 billion kg CO2e.

AECOM has set ambitious climate commitments, with targets approved by the Science Based Targets initiative (SBTi). The company aims to achieve net-zero greenhouse gas (GHG) emissions across its value chain by FY2040, using FY2018 as a base year.

For near-term targets, AECOM commits to reducing absolute Scope 1 and 2 GHG emissions by 60% by FY2030 from a FY2018 base year. They also aim to reduce absolute Scope 3 GHG emissions from purchased goods and services, capital goods, and business travel by 50% by FY2030 from a FY2018 base year. For long-term targets, the company is committed to a 90% reduction in absolute Scope 1 and 2 GHG emissions by FY2040 and a 90% reduction in absolute Scope 3 GHG emissions from purchased goods and services, capital goods, and business travel by FY2040, both from a FY2018 base year. These targets are consistent with reductions required to keep warming to 1.5°C.

AECOM was the first company in the engineering sector to have its emission reduction targets approved by the SBTi, aligning with the goals of the Paris Agreement. They also signed the Climate Pledge in April 2021.
