About This Report

As North America’s leading provider of comprehensive waste management services, our mission is to maximize resource value while minimizing impact in order to further both economic and environmental sustainability for all of our stakeholders1. Transparency is an important part of this mission. Accordingly, we are committed to consistent public disclosure and discussion of our own progress through the publication of a sustainability report every two years. In off years, we update key data and content to the most recent full year.

Our last comprehensive report was published in 2013 with available data and key discussion items updated in 2014. This report generally covers subject matter for 2015 and early 2016 for Waste Management’s wholly owned operations, all of which are located in North America. All data is for the year ended December 31, 2015, except where noted1. Notes on the scope of the data, including changes to methodology from the prior reporting period, are included either with charts or in footnotes. This report has been prepared in accordance with Global Reporting Initiative (GRI) G4 Core guidelines.

For more about our reporting, please see Forward-Looking Information at the end of this section.

Assurance

We currently do not seek external assurance for this report. Our 2015 GHG emissions inventory has been assured by Lloyd’s Register Quality Assurance Ltd. The inventory includes direct emissions and indirect (Scope 3) GHG emissions from the following sources:

  • Purchased goods and services
  • Capital goods
  • Fuel- and energy-related activities (not included in Scope 1 or Scope 2)
  • Business travel
  • Employee commuting
  • Downstream leased assets

The complete assurance statement is available as part of our CDP filing here.

Materiality

The content of this report has been compiled and organized based upon insights from a materiality assessment conducted by an internal team. This team is charged with ongoing stakeholder engagement, including participation in key business and multistakeholder organizations listed in the Appendix of this report, media relations, disclosure of sustainability information for sales and marketing purposes, and completion of sustainability survey requests. The materiality process involved four steps:

  • Identification of potential material topics by reviewing GRI aspects, benchmarking against key corporate peers and analyzing past Waste Management reports, which themselves have been amended over time to reflect feedback from customers, community representatives, employees and non-governmental organizations (NGOs).
  • Inventory of aspects and topics most important to external stakeholders, primarily NGOs and customers and their supply chain vendors, based upon requests, surveys and ongoing engagement since the last reporting period.
  • Survey of internal stakeholders, which included more than 40 cross-functional directors and subject matter experts, to determine which topics impact our business most. Participants were queried about topics most likely to trigger impacts over the next five years and over which Waste Management is able to exercise control.
  • Normalization and ranking of results from internal and external stakeholders determined by breaking scores into quintiles for scoring purposes by an independent statistician.
