Our ESG Strategy

We actively work to promote our growth and operations sustainably and responsibly across our six regions. The BXP ESG strategy is to conduct our business, the development, ownership, and operation of new and existing buildings, in a manner that contributes to positive economic, social, and environmental outcomes for our customers, shareholders, employees, and the communities we serve. Our investment philosophy is shaped by our core strategy of long-term ownership and our commitment to our communities and the centers of commerce and civic life that make them thrive. We are focused on developing and maintaining healthy, high-performance buildings, while simultaneously mitigating operational costs and the potential external impacts of energy, water, waste, greenhouse gas emissions, and climate change. Positive social impact is also of great importance to BXP and our employees, which is exhibited by our commitments to charitable giving, volunteerism, public realm investments, and promoting diversity and inclusion in the workplace and our communities. Through these efforts, we demonstrate that operating and developing commercial real estate can be conducted with conscious regard for the environment and broader society while mutually benefiting our stakeholders

ESG Leadership

We continue to address the needs of our stakeholders by making efforts to maintain and improve our ESG performance across three pillars: climate action, climate resilience, and social good. BXP is a widely recognized industry leader in ESG. 2021 ESG highlights include:

  • BXP ranked among the top real estate companies in the GRESB assessment, earning a sixth consecutive
    5-Star rating. 2021 was the tenth consecutive year that BXP earned the GRESB “Green Star” designation.
  • BXP was named to Newsweek’s America’s Most Responsible Companies 2022 list for the second consecutive year. BXP ranked first in the real estate industry with a ranking increase from 56th overall out of 421 companies in 2020 to 31st overall out of 499 companies in 2021.
  • BXP was named to the Dow Jones Sustainability Index (DJSI) North America. BXP was one of nine real estate companies that qualified and the only office REIT in the index, scoring in the 93rd percentile of the real estate companies assessed for inclusion.
  • BXP ranked #4 on the inaugural Forbes Green Growth 50, a list focused on large American corporations
    that have reduced greenhouse gas emissions while simultaneously growing earnings.
  • BXP was named an ENERGY STAR Partner of the Year – Sustained Excellence Award Winner.
  • BXP was named a Green Lease Leader at the highest Gold level by the Institute for Market Transformation and the U.S. Department of Energy for exhibiting a strong commitment to high performance and sustainability in buildings and best practices in leasing.

Our leadership position is due, in part, to our establishment of environmental goals, the periodic reporting of progress towards our goals, and the achievement of these goals. We have publicly adopted energy, emissions, water, waste, and building certification goals that establish reduction targets aligned with the United Nations Sustainable Development Goals. As of the end of 2020, the combined impacts of efficiency measures, renewable energy, and reduced physical occupancy due to the COVID-19 pandemic resulted in a 41% decrease in energy use intensity and an 86% reduction in greenhouse gas emissions intensity below a 2008 base year. We have also aligned our emissions reduction targets with climate science and in 2020 became the first North American office REIT to establish an emissions reduction target ambition in line with a 1.5°C trajectory, the most ambitious designation available at the time of submission under the Science Based Targets initiative. In April 2021, we affirmed our commitment to achieving carbon-neutral operations (for direct and indirect scope 1 and scope 2 emissions) by 2025 from our occupied and actively managed buildings where we have operational control.

We are focused on developing, owning, and operating healthy and high-performance buildings. BXP is a corporate member of the U.S. Green Building Council® (“USGBC”) and has a long history of green buildings under USGBC’s Leadership in Energy and Environmental Design™ (LEED®) rating system. We have LEED-certified 28.3 million square feet of our portfolio, of which 98% is certified at the highest Gold and Platinum levels. In 2018, we announced a partnership with a leading healthy building certification system, Fitwel, to support healthy building design and operational practices across our portfolio, becoming a Fitwel Champion. We completed our Fitwel Champion commitments and have added 16.7 million square feet of Fitwel certified buildings. In response to the 12 COVID-19 pandemic, we completed the Fitwel Viral Response Module Enterprise and Asset-level Certification at all
actively managed office properties.

Sustainability Accounting Standards Board (“SASB”) Disclosures

The Real Estate Sustainability Accounting Standard issued by SASB in 2018 proposed sustainability accounting metrics designed for disclosure in mandatory filings, such as the Annual Report on Form 10-K, and serves as the framework against which we have aligned our disclosures for sustainability information. The recommended energy and water management activity metrics for the real estate industry include energy consumption data coverage as a percentage of floor area (“Energy Intensity”); percentage of the eligible portfolio that is certified ENERGY STAR® (“ENERGY STAR certified”); total energy consumed by portfolio area (“Total Energy Consumption”); water withdrawal as a percentage of total floor area (“Water Intensity”); and total water withdrawn by portfolio area (“Total Water Consumption”). Our energy and water data is collected from utility bills and submeters and is assured by an independent, third-party assurance expert, which includes all SASB 2020 energy and water metrics. For more information on the independent, third-party assurance expert and the methodology used to assure the data, refer to “Reporting” below. During the 2020 calendar year, 52 buildings representing 49% of our eligible portfolio were ENERGY STAR certified. A licensed professional has verified all ENERGY STAR applications. The charts in our SASB disclosure detail our Energy Intensity, Total Energy Consumption, Water Intensity, and Total Water Consumption for 2015 through 2020 for which data were available on occupied and actively managed buildings where we had operational control.
