Compared to 2024, the total operational greenhouse gas (GHG) emissions of Zalaris increased by 7.75%, suggesting that the company faced challenges in reducing its emissions from its core operations.a
In 2025, the total Scope 1 emissions of Zalaris were 162.75 metric tons of CO₂ equivalent (tCO₂e).a
Compared to the previous year (2024), Zalaris's Scope 1 emissions decreased by 5.89%, highlighting the company's efforts to lower direct emissions from assets it owns or controls.a
In 2025, Zalaris reported Scope 2 greenhouse gas (GHG) emissions of 316.35 tCO₂e using the market-based method and 368.04 tCO₂e using the location-based method.a
Compared to the previous year (2024), Zalaris's Scope 2 emissions (Location-Based) rose by 15.13% in 2025, suggesting that the company faced challenges in reducing emissions from purchased electricity and energya
In 2025, Zalaris reported its Scope 2 emissions using the market-based method and using the location-based method.a
In 2025, Zalaris reported 4,978.28 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 Zalaris 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, Zalaris reported total Scope 3 emissions of 4,978.28 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 (2024), Zalaris's Scope 3 emissions increased by 13.96%, suggesting that the company faced challenges in reducing emissions across its value chain.a
In 2025, Zalaris 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 Zalaris's Scope 3 emissions were:a
In 2025, Zalaris reported Scope 1 greenhouse gas (GHG) emissions of 162.75 tCO₂e and total revenues of USD 149 millions. This translates into an emissions intensity of 1.09 tCO₂e per millions USD.a
In 2025, Zalaris reported a Scope 1 emissions intensity of 1.09 tCO₂e per millions USD. Compared to the peer group median of 1.33, this places the company below its industry benchmark, indicating it is more carbon-efficient than most competitors.a
In 2025, Zalaris ranked 12 out of 25 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Zalaris is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Zalaris reported a total carbon footprint of 5,509.07 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 13.33% increase compared to 2024, suggesting a rise in emissions across its operations or value chain.a
The largest contributor to Zalaris's total carbon footprint was Scope 3 emissions, accounting for 90.37% of the company's total carbon footprint, followed by Scope 2 emissions at 6.68%.a
