In 2025, CSL 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) and Scope 2 (indirect emissions from purchased energy).
However, CSL has not published a category-level breakdown of its Scope 3 emissions, limiting visibility into specific value chain sources.

In 2025, the total operational greenhouse gas (GHG) emissions of CSL amounted to 286,000 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 2024, the total operational greenhouse gas (GHG) emissions of CSL decreased by 17.82%, showing that the company has made progress in taking action to reduce the climate impact of its operations.a
In 2025, the total Scope 1 emissions of CSL were 135,000 metric tons of CO₂ equivalent (tCO₂e).a
Compared to the previous year (2024), CSL's Scope 1 emissions increased by 1.5%, suggesting that the company faced challenges in reducing emissions from its directly owned or controlled operations.a
In 2025, CSL reported Scope 2 greenhouse gas (GHG) emissions of 151,000 tCO₂e using the market-based method.a
Compared to the previous year (2024), CSL's Scope 2 emissions (Market-Based) fell by 29.77% in 2025, showing that the company has made progress in taking action to reduce the climate impact of its energy consumption.a
In 2025, CSL reported its Scope 2 emissions using the market-based method.a
In 2025, CSL reported Scope 1 greenhouse gas (GHG) emissions of 135,000 tCO₂e and total revenues of USD 23,347 millions. This translates into an emissions intensity of 5.78 tCO₂e per millions USD.a
In 2025, CSL reported a Scope 1 emissions intensity of 5.78 tCO₂e per millions USD. Compared to the peer group median of 3.91, this places the company above its industry benchmark, indicating it is less carbon-efficient than most competitors.a
In 2025, CSL ranked 17 out of 24 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
CSL is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
