Greenhouse Gas Inventory


As a responsible organization whose business activities have a global reach, Maximus has an important role in contributing efforts to reduce our impact on the environment of the communities in which we live and work.

We primarily provide business process outsourcing (BPO) services to local, state, federal, and international government and therefore have a relatively small environmental footprint. However, we remain committed to ensuring responsible environmental practices in each of our communities. This is done through energy reduction efforts, such as energy-saving lighting in our facilities which provides not only greener solutions, but also more cost-effective measures for the Company.

In 2019, Maximus launched an initiative to begin measuring and disclosing our environmental impact, guided by global standardized frameworks such as the Greenhouse Gas (GHG) Protocol, the Carbon Disclosure Project, and the United States Environmental Protection Agency.

Our overall sustainability strategy includes voluntary measures to minimize GHG emissions and energy use, track environmental risks, and improve environmental data collection and visibility. Our strategy is a cross-functional effort working with corporate real estate, corporate responsibility, finance, and operations. Updates are regularly reported to the Board of Director’s Nominating and Governance Committee, ensuring continued progress towards meeting goals of reducing environmental impact and risk exposures across the organization.

GHG Inventory Boundaries and Scope

In alignment with global standardized frameworks, the scope of the inventory includes Maximus owned or leased facilities, vehicles, and utilities within the United States for fiscal year 2019 and incorporate the following boundaries:

Scope 1: Direct Energy Use

  • Fuel consumed onsite in company-owned facilities or in leased facilities, where fuel is purchased directly by the company and not by the landlord
  • Motor vehicle fuel purchased by the company for use in company-owned or company-leased vehicles
  • Fuel purchased by the company for use in company-owned or company-leased equipment, such as generators
  • Industrial process emissions, which is not applicable for Maximus

Scope 2: Indirect Energy Use

  • Electricity, steam, and chilled water utilities, purchased by the company for use in company-owned facilities or in leased facilities where the utility bill is paid directly by the company and not by the landlord
  • Utilities provided by a landlord and billed by the landlord separately from base rent when the billed utilities are metered and benefit only the specific space occupied by the company

As a note, Maximus underwent a large-scale acquisition during fiscal year 2019, as well as began opening new sites as part of the Census 2020 contract ramp up. As a result, these acquired and newly added site locations are included in the GHG inventory for the period during which the Company took responsibility for utility payments as part of the acquisition transition or opening of a new location.
