Marriott

Marriott International, Inc. reported its Scope 1 emissions as approximately 1.27 billion kg CO2e in 2025. Market-based Scope 2 emissions were approximately 5.36 billion kg CO2e, and Scope 3 emissions were approximately 12.45 billion kg CO2e, including approximately 5.89 billion kg CO2e from franchises, about 562 million kg CO2e from capital goods, approximately 605 million kg CO2e from employee commute, about 3.58 billion kg CO2e from purchased goods and services, approximately 178 million kg CO2e from waste generated in operations, and about 1.39 billion kg CO2e from fuel and energy-related activities.

Marriott has set Science Based Targets initiative (SBTi) approved targets to reach net-zero greenhouse gas emissions across its value chain by 2050. This includes a near-term commitment to reduce absolute Scope 1 and 2 GHG emissions by 46.2% by 2030 from a 2019 base year. Additionally, the company aims to reduce 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. By 2028, Marriott also commits that 22% of its suppliers, by emissions covering purchased goods and services, capital goods, and upstream transportation and distribution, will have science-based targets. For the long term, Marriott aims to reduce absolute Scope 1 and 2 GHG emissions by 90% by 2050 from a 2019 base year, and absolute Scope 3 GHG emissions by 90% within the same timeframe. These targets are consistent with reductions required to keep global warming to 1.5°C.

Beyond SBTi commitments, Marriott has also set a document-based goal to reduce carbon emissions by 30% by 2025, from a 2016 baseline, as part of its 2025 Sustainability and Social Impact Goals. They also aim to reduce carbon intensity per square metre of conditioned space by 30% from a 2016 baseline for both Scope 1 and Scope 2 emissions by 2025. In 2020, Marriott reported surpassing its 30% carbon intensity reduction target for both its managed and franchised portfolios since 2016, with reductions of 31.47% and 32.92% respectively. However, these reductions were not considered achieved due to low hotel occupancy during the COVID-19 pandemic.
