Marriott

Marriott International, based in the US, is committed to reducing its carbon footprint. For the year 2025, the company reported total greenhouse gas emissions of approximately 19.7 billion kg CO2e. This breaks down into roughly 1.27 billion kg CO2e for Scope 1 emissions, and approximately 5.36 billion kg CO2e for Scope 2 emissions (market-based). Scope 3 emissions were substantial, totalling around 12.45 billion kg CO2e, with significant contributions from franchises (approximately 5.89 billion kg CO2e) and purchased goods and services (approximately 3.58 billion kg CO2e).

Marriott has set several reduction targets. Notably, they aimed to reduce absolute carbon emissions by 30% by 2025 against a 2016 baseline. Additionally, they aimed to decrease carbon intensity per square metre of conditioned space by 30% by 2025, also from a 2016 baseline.

More broadly, Marriott International has made a commitment to reach net-zero greenhouse gas emissions across its value chain by 2050. As part of their Science Based Targets initiative (SBTi) commitments, they aim to reduce absolute Scope 1 and 2 GHG emissions by 46.2% by 2030 from a 2019 base year. They also commit to reducing absolute Scope 3 GHG emissions from fuel and energy-related activities, waste generated in operations, employee commuting, and franchises by 27.5% within the same timeframe. Furthermore, Marriott aims to have 22% of its suppliers, covering purchased goods and services, capital goods, and upstream transportation and distribution, commit to science-based targets by 2028. Their long-term SBTi goal includes reducing absolute Scope 1 and 2 GHG emissions by 90% by 2050 from a 2019 base year.
