In 2024, AECOM completed a corporate carbon footprint assessment and publicly disclosed its greenhouse gas (GHG) emissions according to the GHG Protocol, covering Scope 1 (direct emissions from owned or controlled sources), Scope 2 (indirect emissions from purchased energy) and Scope 3 (indirect emissions across the value chain).
AECOM has also provided a category-level breakdown for 3 out of 15 Scope 3 emissions categories, offering greater transparency into its value chain emissions.

In 2024, the total operational greenhouse gas (GHG) emissions of AECOM amounted to 51,998 metric tons of CO2 equivalent. This figure includes both direct emissions from owned or controlled sources (Scope 1) and indirect emissions from purchased energy (Scope 2).a
Compared to 2023, the total operational greenhouse gas (GHG) emissions of AECOM decreased by 3.45%, showing that the company has made progress in taking action to reduce the climate impact of its operations.ab
In 2024, the total Scope 1 emissions of AECOM were 29,072 metric tons of CO₂ equivalent (tCO₂e).a
Compared to the previous year (2023), AECOM's Scope 1 emissions increased by 22.43%, suggesting that the company faced challenges in reducing emissions from its directly owned or controlled operations.ab
In 2024, AECOM reported Scope 2 greenhouse gas (GHG) emissions of 22,926 tCO₂e without specifying the calculation method.a
Since 2019, AECOM's Scope 2 greenhouse gas (GHG) emissions (Unspecified Calculation Method) have decreased by 82.06%, reflecting a declining long-term trend in Scope 2 emissions over time.ae
In 2024, AECOM reported its Scope 2 emissions using an unspecified methodology.a
In 2024, AECOM reported 1,743,218 metric tons of CO₂ equivalent (tCO₂e) of Scope 3 greenhouse gas (GHG) emissions, representing indirect emissions across its upstream and downstream value chain.a
The 2024 disclosure of AECOM includes a breakdown across 3 of the 15 Scope 3 categories defined by the GHG Protocol, up from 1 in 2023, reflecting improved emissions accounting practices and greater transparency across the company's value chaina
In 2024, AECOM reported total Scope 3 emissions of 1,743,218 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 100% of these emissions originated from upstream activities such as purchased goods and capital goods, while 0% came from downstream activities like product use, distribution, and end-of-life treatment.a
Compared to the previous year (2023), AECOM's Scope 3 emissions decreased by 23.22%, highlighting the company's efforts to lower indirect emissions from its value chain.ab
In 2024, AECOM reported emissions for 3 out of the 15 Scope 3 categories defined by the GHG Protocol.a
The limited disclosure restricts visibility into specific emission sources across the company's value chain.
In 2024, the largest contributors to AECOM's Scope 3 emissions were:a
In 2024, AECOM reported Scope 1 greenhouse gas (GHG) emissions of 29,072 tCO₂e and total revenues of USD 16,105 millions. This translates into an emissions intensity of 1.81 tCO₂e per millions USD.a
In 2024, AECOM reported a Scope 1 emissions intensity of 1.81 tCO₂e per millions USD. Compared to the peer group median of 12.53, this places the company below its industry benchmark, indicating it is more carbon-efficient than most competitors.a
In 2024, AECOM ranked 4 out of 25 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
This places AECOM among the top performers, with one of the lowest emissions intensities relative to peers.a
In 2024, AECOM reported a total carbon footprint of 1,795,216 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 22.76% decrease compared to 2023, indicating progress in reducing its overall greenhouse gas output.ab
The largest contributor to AECOM's total carbon footprint was Scope 3 emissions, accounting for 97.1% of the company's total carbon footprint, followed by Scope 1 emissions at 1.62%.a
