Comcast

Comcast, a US-based post and telecommunication services company, reported total market-based carbon emissions of approximately 10.8 billion kg CO2e in 2025. This includes about 407 million kg CO2e from Scope 1 emissions, 960 million kg CO2e from Scope 2 (market-based), and 9.5 billion kg CO2e from Scope 3 emissions. Key contributors to Scope 3 emissions in 2025 included downstream leased assets (3.86 billion kg CO2e), purchased goods and services (2.71 billion kg CO2e), and capital goods (1.83 billion kg CO2e).

Looking back, Comcast's total market-based emissions were approximately 12.3 billion kg CO2e in 2019, 12.4 billion kg CO2e in 2023, and 12.3 billion kg CO2e in 2024.

Comcast has set several significant climate commitments. The company aims to be carbon neutral by 2035 for Scope 1 and 2 market-based emissions across its global operations. Furthermore, Comcast has near-term Science Based Targets initiative (SBTi) approved targets:

• To reduce absolute Scope 1 and 2 GHG emissions by 50% by 2030, from a 2019 base year.
• To reduce absolute Scope 3 emissions from fuel- and energy-related activities, business travel, employee commuting, use of sold products, and downstream leased assets by 27.5% by 2030, from a 2019 base year.
• Comcast also commits that by 2029, at least 36% of its Scope 3 emissions from purchased goods and services, capital goods, upstream transportation and distribution, waste generated in operations, and upstream leased assets will come from suppliers with science-based targets.

Comcast has reported progress towards these goals, noting a 38% reduction in Scope 1 and 2 emissions from its 2019 base year through 2022.
