Managing Our Climate Impact

Our extensive operational decarbonization efforts support our Scope 1 and 2 greenhouse gas (GHG) emissions goals, which have been validated by the Science Based Targets initiative (SBTi). We have reduced our GHG emissions by 22% from a 2021 baseline through meaningful actions towards our science-based target, including:

• Implementing landfill cover and capping systems to limit the escape of landfill gas
• Installing and expanding gas collection and capture systems to capture landfill gas more effectively
• Increasing generation of renewable natural gas and allocating to our collection fleet

Landfill Emissions Measurement Innovation

WM is advancing landfill emissions measurement through a layered approach that integrates multiple detection and quantification methods and aims to account for the complex factors influencing methane emissions, such as topography, weather and operational activities. This focus on precise data allows for better optimization of landfill gas capture and progress toward sustainability goals. By collaborating with various stakeholders and exploring innovative solutions, WM aims to drive meaningful reductions in emissions and enhance environmental stewardship.

Growing Our Alternative Fuel Fleet

With the largest alternative fuel fleet in the industry in North America, WM has the unique opportunity to drive substantial emissions reduction impact by transitioning a majority of our fleet from diesel to natural gas.

In 2024, we:

• Accomplished our objective for 70% of our collection fleet to be alternative fuel vehicles a year early¹
• Allocated 74% of alternative fuel consumption to renewable natural gas (RNG), accomplishing our objective for 50% of alternative fuel vehicles to run on renewable natural gas by 2025
• Reduced fleet emissions approximately 30% since 2021
