¹ This is a non-GAAP financial measure. Please see the footnotes and tables that accompany WM's press releases dated 1/31/2023; 2/2/2022; 2/18/2021; 2/13/2020 and 2/14/2019, available at investors.wm.com, for more information about WM's use of non-GAAP measures and a reconciliation to the most comparable GAAP measures.

² The decrease in Enterprise Net Promoter Score is correlated to severe weather events which created significant disruptions in WM's ability to safely service these areas.

³ Alternative Energy vehicles include vehicles that run on compressed natural gas (CNG), liquefied natural gas (LNG) and electricity.

⁴ In 2022, WM updated our methodology for calculating percent of alternative energy vehicles fueled with renewable natural gas (RNG) based on enhanced data availability and to take a more conservative calculation methodology. In 2022, we allocated approximately 50 million RNG gallons of gasoline equivalent, and are on track to allocate RNG to cover fuel usage by our collection fleet by 2026.

⁵ Facility count is inclusive of WM owned facilities plus third party facilities operating on WM landfills

⁶ "Other" includes specialty materials such as used oil, tires and textiles.

⁷ The decrease in Total Recycled Materials in 2022 primarily resulted from recycling facilities shutdowns for facility upgrades and a reduction in tons recovered from 3rd parties and organics.

Our GHG Emissions Inventory is 3rd party reviewed and verified annually.

⁸ In 2022, we reduced Scope 1 & 2 emissions by 10%, which is driven by a reduction in landfill emissions and collection fleet.
⁹ Location Based reflects emissions from total electricity consumption. Market Based reflects emissions from retirement of Renewable Energy Credits (RECs) in accordance with the Greenhouse Gas Protocol Accounting Standard.

¹⁰ We continue to improve our Scope 3 accounting and transparency year over year by working closely with the Supply Chain team and our suppliers, and aligning with best practice methodologies. Not only does this result in fluctuations in reported emissions, but may lead us to shift emissions into different categories, eliminating some while expanding others.

¹¹ Biogenic emissions are reported separately from WM's Corporate GHG Inventory in line with GHG Protocol reporting standard. These emissions are considered carbon neutral as they derive from decomposition of biological material. Biogenic Scope 2 emissions are associated with retired RECs from landfill-gas-to-energy.

¹² Carbon Intensity metrics include Scope 1 & 2 emissions normalized to $M net revenue, tons of waste disposed and 1,000 miles driven.
¹³ Avoided GHG Emissions per CO2e is calculated by dividing total potential emissions avoided from Renewable Energy Generation, Reuse and Recycling of Materials and Carbon Permanently Sequestered by direct operating emissions (Scope 1 and 2).

¹⁴ 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. In 2022, WM reported a de minimis change in landfill gas captured related to timing of gas generation and forementioned factors.

¹⁵ Equipment Capacity presents MWs of capacity at WM renewable energy facilities only.
¹⁶ Landfill gas converted to energy is a measure of energy produced via WMRE facilities both WM owned and third -party operated. Note, landfill gas processed at a WMRE facility has a higher energy content than the enterprise-wide average energy content.
¹⁷ In 2022, the decrease in Landfill Gas Converted to Energy for Sale/Use was due to several facilities temporarily closing for renovations to convert generation from landfill gas-to-electricity to renewable natural gas.

¹⁸ Fuels is inclusive of collection fleet, off-road fleet, facility heating, fuels used in operations and aviation.
¹⁹ In 2021 and 2022, Renewable Electricity is comprised of Renewable Energy Credits (RECs). See Scope 2 Market Based emissions above.

²⁰ MWh is enterprise-wide energy including electricity and fuels normalized to $M net revenue, tons of waste disposed and 1,000 miles driven.

²¹ TRI data is reported a year behind.

²² Total waste generated in operations is calculated using an average waste and recycling generation tonnage per employee, per day for each of our facility types. Each WM facility type (i.e., landfill, hauling, MRF, office, etc.) has its own waste factor calculated based on historical waste audit data.

²³ Water consumption is municipal water retrieved from our utility bill management system and ground water estimated based on employee count for sites with ground water wells.

²⁴ Minority representation references both racial and ethnic characteristics self-identified by team members.

²⁵ Minority representation references both racial and ethnic characteristics self-identified by team members.
²⁶ The category for two or more races has been included in EEO-1 reporting, and is being integrated to WM's sustainability reporting beginning in 2022.

²⁷ The category for two or more races has been included in EEO-1 reporting, and is being integrated to WM's sustainability reporting beginning in 2022.

²⁸ Minority representation references both racial and ethnic characteristics self-identified by team members.
²⁹ 2022 EEO-1 Table will be filed July 2023.

³⁰ Average hours of training per employee includes training completions tracked in WM’s Talent Management System and an estimate of blended learning techniques (e.g., daily training huddles, weekly safety training, monthly observations and post-training reinforcement methods such as videos and practice sessions) that occur in the field.

³¹ Acres and Projects are actively managed through the Wildlife Habitat Council programs.

³² Diverse representation is voluntarily self-identified. Minority representation references both racial and ethnic characteristics self-identified by team members.

³³ The data presented above is annual total monetary contributions to and spending for political campaigns, political organizations, lobbyists or lobbying organizations, trade associations and other taxexempt groups. Note the amounts are based on the information provided by the association or organization. WM PAC contributions are excluded and can be found in our publicly available disclosure Participation in the Political Process https://investors.wm.com/static-files/3013b95e-be0a-40a7-830f-22cdd9e3c50a

³⁴ The above data represents the portion of monetary contributions or expenditures allocated by trade associations to influence political campaigns or public policy and legislation.

³⁵ WM maintains a SPEAK UP culture where employees are encouraged to report issues and concerns through several channels, including directly to their manager, Human Resources, Compliance and Ethics or directly to the third party administered Integrity Helpline.
