BOSTON–(BUSINESS WIRE)–American Tower Corporation (NYSE: AMT) today announced the release of its 2021 sustainability report. The report outlines the Company’s sustainability strategy which is built upon three core pillars—Environment, Social and Governance (ESG)—and provides a comprehensive overview of the actions the Company is taking as it strives to meet its objectives in these critical areas.

Through a dedicated focus on its sustainability strategy and commitment to positively impacting customers, employees, stockholders, suppliers and its served communities, American Tower continues to make strong advancements within each of its ESG pillars. The report highlights this progress against key quantitative and qualitative sustainability goals, including science-based greenhouse gas (GHG) emissions reduction targets and advancements on diversity, equity and inclusion.

Tom Bartlett, American Tower’s President and Chief Executive Officer, stated, “Our sustainability program is grounded in our strategic priorities to foster a more equitable culture for our employees, improve our operational efficiencies, support the needs of our customers, uphold ethics and integrity at every level of the organization and engage with our local communities. Steadfast commitment to these key priorities will be integral to our continued success, especially as we continue to grow our business in this technology-driven era.”

Key highlights from the 2021 report include:
