Glaxosmithkline

GlaxoSmithKline (GSK), a UK-headquartered pharmaceutical manufacturer, reported Scope 1 emissions of approximately 479 million kg CO2e and Scope 2 (market-based) emissions of 7 million kg CO2e in 2025. In 2024, GSK reported Scope 1 emissions of approximately 521 million kg CO2e, Scope 2 (market-based) emissions of 44 million kg CO2e, and Scope 3 emissions of approximately 8.385 billion kg CO2e. For 2023, the company disclosed Scope 1 emissions of approximately 580 million kg CO2e, Scope 2 (market-based) emissions of 64 million kg CO2e, and Scope 3 emissions of approximately 8.983 billion kg CO2e.

GSK has established robust climate commitments. The company aims for net-zero greenhouse gas emissions across its full value chain by 2045, targeting a 90% absolute reduction from a 2020 baseline across all scopes, with residual emissions neutralised through high-quality offsets. This aligns with Science Based Targets initiative (SBTi) long-term targets for Scope 1, 2, and 3 emissions, all committed to a 90% reduction by 2045 from a 2020 base year.

For near-term targets, GSK commits to an 80% absolute reduction in Scope 1 and 2 GHG emissions by 2030 from a 2020 base year. Similarly, it aims to reduce absolute Scope 3 GHG emissions from specific categories (purchased goods and services, fuel and energy-related activities, upstream transportation and distribution, waste generated in operations, business travel, employee commuting, use of sold products, and end-of-life treatment of sold products) by 80% within the same timeframe. These near-term targets are classified as consistent with a 1.5°C warming trajectory by the SBTi. GSK had previously committed to a 34% reduction in absolute Scope 1 and 2 GHG emissions by 2025 from a 2017 base year, and a 16% reduction in absolute Scope 3 GHG emissions by 2030 from a 2017 base year.

The company also reported a 15% reduction in Scope 1 and 2 carbon emissions in 2021 compared to 2020. GSK signed The Climate Pledge in August 2021, reinforcing its commitment to achieve net-zero carbon emissions by 2040.
