Awarded Highest Honor Given by the ENERGY STAR Program

Boston Properties, Inc. (NYSE: BXP), the largest publicly traded developer, owner, and manager of Class A office properties in the United States, today announced that it has received the 2021 ENERGY STAR Partner of the Year—Sustained Excellence Award from the U.S. Environmental Protection Agency and the U.S. Department of Energy.

The Sustained Excellence award is the highest honor bestowed by the ENERGY STAR program. According to ENERGY STAR, the winners are part of a distinguished group that has made a long-term commitment to fighting climate change and protecting public health through energy efficiency, and they are among the nation’s leaders in driving value for the environment, the economy, and the American people.

BXP continues to be recognized as a well-established leader in energy efficiency and has publicly declared energy use intensity reduction goals. The Company has reduced the energy use intensity of its actively managed office buildings by 27 percent since 2008 and has a standing goal to reduce energy use intensity by 32 percent by 2025. In 2020, 52 BXP buildings earned the ENERGY STAR rating and the Company achieved an average ENERGY STAR score of 79 out of 100 across its actively managed and eligible in-service portfolio.

“ENERGY STAR award-winning partners are showing the world that delivering real climate solutions makes good business sense and promotes job growth,” said EPA Administrator Michael S. Regan. “Many of them have been doing it for years, inspiring all of us who are committed to tackling the climate crisis and leading the way to a clean energy economy.”

“We’re proud of our continuing partnership with the U.S. Environmental Protection Agency and ENERGY STAR,” said Doug Linde, President, BXP. “This recognition underscores our commitment to energy performance and the implementation of energy conservation measures across our portfolio that reduce energy consumption, carbon emissions and operating costs.”

BXP’s commitment to sustainable development and operations has been recognized by numerous industry groups, including the Company’s achievement of the highest 5-star 2020 Global Real Estate Sustainability Benchmark (GRESB) rating, ninth consecutive GRESB Green Star and an “A” disclosure score. The Company completed its Fitwel Champion commitments and was named a 2020 Best in Building Health award winner. LEED certified properties now total more than 27.7 million square feet, more than half of BXP’s actively managed office portfolio, 96% of which are certified at the highest Gold and Platinum levels. BXP was also named one of America’s Most Responsible Companies by Newsweek magazine, ranking 56th on Newsweek's 2021 list of America’s 400 Most Responsible Companies, the highest ranking given to an office REIT and the second highest ranking of any property company. The Company has aligned its emissions reduction targets with climate science and, in 2020, completed the Science Based Targets Initiative approval process.
