Natural Resources Management Continued Partnering to Protect the Planet Truly protecting the planet will require looking beyond our own operations to areas where we can meaningfully partner with others. For the last few years, T-Mobile has joined forces with The Nature Conservancy (TNC) to mobilize our resources and our customers around Earth Day and bolster global conservation efforts. Since 2018, we’ve donated $1.6 million to TNC programs that work to establish environmentally conscious practices to prevent habitat loss and promote biodiversity on a large scale. Through our annual campaigns, we’ve engaged customers through the T-Mobile Tuesdays app to help direct our funding to programs, such as: • Plant a Billion Trees —a major forest restoration program aimed at slowing climate change and biodiversity loss • The Family Forest Carbon Program —a project aimed at helping family and small landowners across the U.S. gain access to resources and capital to improve the health of their forests and fight climate change • Living with Fire —a program to develop and implement fire mitigation strategies that reduce wildfire risks and restore health and diversity to natural lands ENVIRONMENTAL GOVERNANCE To help drive sustainability outcomes across the business, the T-Mobile Sustainability Steering Committee meets quarterly to discuss priority environmental sustainability topics and initiatives. Comprised of executive leaders from cross- functional groups, the committee works to drive a holistic, enterprise-wide discussion and to align sustainability efforts at T-Mobile, as well as ensuring functional visibility, accountability, and engagement in the development of company-wide plans. The committee is co-led by our Executive Vice President and Chief Communications Officer and our Executive Vice President, Corporate Development and Strategy. Key initiatives overseen by the committee are communicated through ESG updates to the Nominating and Corporate Governance Committee. 2021 CORPORATE RESPONSIBILITY REPORT OUR PEOPLE OUR GOVERNANCE OUR COMMUNITIES THE NUMBERS AND SMALL PRINT 62 OUR COMPANY THE ENVIRONMENT
