Energy is Renewable

WM’s approach to climate action is grounded in a Science Based Targets initiative (SBTi)-validated commitment to reduce Scope 1 and 2 GHG emissions by 42% by 2031 from a 2021 baseline¹. Since establishing this target, WM has achieved a 27% reduction in combined Scope 1 and 2 emissions. This sustained progress reflects disciplined execution focused on our highest-impact sources, particularly landfill operations and fleet, which accounts for nearly 90% of total Scope 1 and 2 emissions.

The keys to success for 2025 GHG emissions reductions include:

1. The most significant driver of Scope 1 reductions has been the implementation of landfill emissions reduction projects, including improved landfill gas collection and control systems. These efforts captured 84% of landfill gas in 2025, further advancing our capture performance and enabling RNG production.
2. Transitioning fleet energy use toward alternative fuels such as CNG. In 2025, 93% of fuel in our alternative fuel fleet was allocated to RNG, up from 74% in 2024.
3. A key contributor to Scope 2 emissions reductions has been renewable energy procurement. Through the purchase of Renewable Energy Certificates (RECs) and Renewable Energy Guarantees of Origin (REGOs), we offset approximately 60% of our total electricity consumption globally, including 100% of electricity consumption across our United Kingdom operations.

¹ The target boundary includes land-related emissions and removals from bioenergy feedstocks.

WM applies a layered approach Landfill Measurement Technology that integrates satellite, aircraft, drone and ground-based technologies to account for the complex factors influencing methane emissions, such as topography, weather and operational activities.

In 2025, we expanded comparative measurement efforts across our landfill network, scaling satellite measurements to a monthly cadence at 45 sites and conducting at least one aircraft survey at approximately 100 sites. Consistent with findings from controlled-release and peer-reviewed studies, high-resolution aircraft data proved effective in identifying localized emission sources, prompting plans to expand aerial monitoring frequency to monthly at approximately 15 sites and quarterly at nearly 50 sites in early 2026.

These efforts help us collect more landfill gas for beneficial use. In 2025, we collected 84% of landfill gas¹.

¹ Landfill gas generated from waste is cyclical over a period of decades. The amount and rate of gas generation is dependent on several factors, including waste volume, composition, climatic factors and operational controls.

WM operates North America’s largest alternative-fuel fleet in the industry, making fleet operations a central lever in our GHG emissions reduction strategy.

In 2025, we:

• Allocated renewable natural gas to 93% of our alternative fuel fleet’s fuel consumption¹.
• Opened a $10 million CNG fleet facility in Tupelo, Mississippi, that can fuel and maintain up to 26 vehicles at a time.
• Operated six mobile integrated gas stations, which can be deployed within three to seven days to provide fueling capability anywhere in North America.
• Reached a 44% estimated reduction in fleet emissions since 2021.

¹ Alternative Fuel Vehicles in Collection Fleet includes Core Solid Waste and Recycling Vehicles that run on compressed natural gas (CNG) and liquefied natural gas (LNG) and does not account for on-road hours.
