Compared to the previous year (2024), Weir Group's Scope 2 emissions (Location-Based) have remained relatively stable, indicating that Weir Group's emissions have plateaued with no significant change in its energy consumption footprint.a
In 2025, Weir Group reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, Weir Group reported 20,371,252 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 2025 disclosure of Weir Group includes a breakdown across 13 of the 15 Scope 3 categories defined by the GHG Protocol, matching the level of disclosure in 2024, demonstrating consistent Scope 3 emissions reporting coverage year over year.a
In 2025, Weir Group reported total Scope 3 emissions of 20,371,252 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 2.8% of these emissions originated from upstream activities such as purchased goods and capital goods, while 97.2% came from downstream activities like product use, distribution, and end-of-life treatment.a
Compared to the previous year (2024), Weir Group's Scope 3 emissions decreased by 25.73%, highlighting the company's efforts to lower indirect emissions from its value chain.a
In 2025, Weir Group reported emissions for 13 out of the 15 Scope 3 categories defined by the GHG Protocol.a
This reflects a high level of granularity and transparency in the company's emissions reporting.
In 2025, the largest contributors to Weir Group's Scope 3 emissions were:a
In 2025, Weir Group reported Scope 1 greenhouse gas (GHG) emissions of 65,072 tCO₂e and total revenues of USD 3,454 millions. This translates into an emissions intensity of 18.84 tCO₂e per millions USD.a
In 2025, Weir Group reported a Scope 1 emissions intensity of 18.84 tCO₂e per millions USD. Compared to the peer group median of 7.07, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, Weir Group ranked 20 out of 25 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Weir Group is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Weir Group reported a total carbon footprint of 20,523,014 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 25.6% decrease compared to 2024, indicating progress in reducing its overall greenhouse gas output.a
The largest contributor to Weir Group's total carbon footprint was Scope 3 emissions, accounting for 99.26% of the company's total carbon footprint, followed by Scope 2 emissions at 0.42%.a
