Comcast's reported carbon emissions

Comcast's carbon emissions for 2025 are reported at approximately 11.4 billion kg CO2e. This total is comprised of Scope 1 emissions of approximately 407 million kg CO2e, Scope 2 market-based emissions of approximately 960 million kg CO2e, and Scope 3 emissions of approximately 9.55 billion kg CO2e. The most significant contributors to Scope 3 emissions in 2025 include downstream leased assets at approximately 3.86 billion kg CO2e and purchased goods and services at approximately 2.71 billion kg CO2e. In 2024, Comcast's total emissions were approximately 12.3 billion kg CO2e, with Scope 1 at approximately 413 million kg CO2e, Scope 2 market-based at approximately 1.13 billion kg CO2e, and Scope 3 at approximately 10.79 billion kg CO2e. The leading Scope 3 categories for 2024 were downstream leased assets (approximately 4.22 billion kg CO2e) and purchased goods and services (approximately 3.47 billion kg CO2e). For 2023, total emissions were approximately 12.5 billion kg CO2e, including Scope 1 at approximately 429 million kg CO2e, Scope 2 market-based at approximately 1.18 billion kg CO2e, and Scope 3 at approximately 10.89 billion kg CO2e. Downstream leased assets and purchased goods and services were again the largest Scope 3 contributors. Comcast has set a primary sustainability objective to achieve carbon neutrality across its global operations for Scope 1 and Scope 2 market-based emissions by 2035. The company has also committed to reducing absolute Scope 1 and 2 GHG emissions by 50% by 2030 from a 2019 base year. Furthermore, Comcast aims to reduce absolute Scope 3 GHG emissions from specific categories, including fuel- and energy-related activities, business travel, employee commuting, use of sold products, and downstream leased assets, by 27.5% by 2030, also from a 2019 base year. An additional engagement target is to partner with suppliers so that by 2029, at least 36% of Scope 3 emissions from purchased goods and services, capital goods, upstream transportation and distribution, waste generated in operations, and upstream leased assets originate from suppliers with a science-based target. The company reported a 38% reduction in Scope 1 and 2 emissions from its 2019 base year through 2022.
