In 2025, Halma reported 981,851 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 Halma includes a breakdown across 7 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, Halma reported total Scope 3 emissions of 981,851 metric tons of CO₂ equivalent (tCO₂e).a
Approximately 7.37% of these emissions originated from upstream activities such as purchased goods and capital goods, while 92.63% came from downstream activities like product use, distribution, and end-of-life treatment.a
Since 2020, Halma's Scope 3 emissionshave remained relatively stable, indicating that Halma's emissions have plateaued with no significant change in its value chain footprint.a
Compared to the previous year (2024), Halma's Scope 3 emissions remained relatively stable, indicating that Halma's emissions have plateaued with no significant change in its value chain footprint.a
In 2025, Halma reported emissions for 7 out of the 15 Scope 3 categories defined by the GHG Protocol.a
This partial disclosure allows for some insight into the company's indirect impacts.
In 2025, the largest contributors to Halma's Scope 3 emissions were:a
In 2025, Halma reported Scope 1 greenhouse gas (GHG) emissions of 4,128 tCO₂e and total revenues of USD 2,909 millions. This translates into an emissions intensity of 1.42 tCO₂e per millions USD.a
In 2025, Halma reported a Scope 1 emissions intensity of 1.42 tCO₂e per millions USD. Compared to the peer group median of 29.01, this places the company below its industry benchmark, indicating it is more carbon-efficient than most competitors.a
In 2025, Halma ranked 4 out of 24 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
This places Halma among the top performers, with one of the lowest emissions intensities relative to peers.a
In 2025, Halma reported a total carbon footprint of 997,183 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 1.74% increase compared to 2024, suggesting a rise in emissions across its operations or value chain.a
The largest contributor to Halma's total carbon footprint was Scope 3 emissions, accounting for 98.46% of the company's total carbon footprint, followed by Scope 2 emissions at 1.12%.a
