Comcast

Comcast, a US-based Post and telecommunication services company, reported total carbon emissions of approximately 10.9 billion kg CO2e in 2025. This figure comprises 407 million kg CO2e from Scope 1 emissions, 960 million kg CO2e from Scope 2 market-based emissions, and 9.545 billion kg CO2e from Scope 3 emissions.

In 2024, the company's total emissions were about 12.33 billion kg CO2e, with Scope 1 at 413 million kg CO2e, Scope 2 market-based at 1.127 billion kg CO2e, and Scope 3 at 10.789 billion kg CO2e. Looking back to 2023, total emissions stood at approximately 12.514 billion kg CO2e, consisting of 429 million kg CO2e from Scope 1, 1.184 billion kg CO2e from Scope 2 market-based, and 10.89 billion kg CO2e from Scope 3.

Comcast has set ambitious climate commitments, including a goal to be carbon neutral by 2035 for Scope 1 and 2 market-based GHG emissions across its global operations. The company aims to reduce its Scope 1 and Scope 2 emissions to near zero by mid-decade (by 2025). Furthermore, Comcast commits to reducing absolute Scope 1 and 2 GHG emissions by 50% by 2030 from a 2019 base year. For Scope 3 emissions, Comcast commits to a 27.5% reduction by 2030 from a 2019 base year for fuel- and energy-related activities, business travel, employee commuting, use of sold products, and downstream leased assets.

The company has also committed 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. These near-term targets for Scope 1 and 2 are classified as consistent with a 1.5°C warming scenario by the Science Based Targets initiative (SBTi). Between 2019 and 2022, Comcast reported a 38% reduction in Scope 1 and 2 emissions from its 2019 base year.
