I am pleased to present BBH’s 2025 Stewardship Report, highlighting our sustainability program and the progress achieved over the past year.

In 2025, the global conversation around corporate sustainability grew more complex and polarizing. Initiatives related to environmental stewardship, workforce inclusion, and responsible business practices faced heightened scrutiny amid shifting political and cultural dynamics. This occurred against the backdrop of macroeconomic and geopolitical instability, as well as the promise and ethical questions raised by the rapid integration of artificial intelligence across society and business. Together, these dynamics have led many companies to question whether to stay the course or recalibrate their sustainability strategies.

At BBH, we remain steadfast in our commitment to sustainability. As Managing Partner of a private bank, I recognize that our unique position at the intersection of capital, families, and institutions brings with it a profound responsibility to conduct our business ethically and make a positive impact on our clients, employees, and communities.

Our sense of duty forms the basis of our commitment to sustainability—an enduring dedication to creating and protecting long-term value and well-being that has guided us for over 200 years. Our private ownership structure and culture of independent thinking empower us to take a long-term perspective and uphold our core values, rather than being swayed by shifting public sentiment. At BBH, we firmly believe that acting sustainably and ethically is not only the right thing to do; it is also sound business practice.

OUR PROGRESS

Since we first began reporting our greenhouse gas (GHG) emissions in 2019, we have strived to enhance operational efficiencies each year to reduce our emissions and improve our carbon accounting methods. From our 2019 baseline, we have achieved an overall emissions reduction of 32%. In 2025, we began a third-party emissions verification engagement to help strengthen our data collection processes and calculation methodologies, ensuring accuracy and completeness. This will provide BBH with an extra layer of confidence in the data we report as we seek to more fully understand our impact on the environment and comply with emissions disclosure regulations. “At BBH, we firmly believe that acting sustainably and ethically is not only the right thing to do, it is also sound business practice.”

We also created a more detailed Supplier Code of Conduct (Code) that holistically describes our sustainability expectations for our material vendors. Our updated Code encourages our suppliers to align more closely with our values while also helping reduce conduct and compliance risks, and includes expanded expectations related to human rights, environmental responsibility, and business ethics. BBH’s employee well-being program focuses on supporting BBHers’ mental and physical health, financial well-being, and family care. In 2025, we expanded our benefits to further support BBHers physically, financially, and personally. In partnership with UnitedHealthcare, we launched a preventative care campaign across the U.S., encouraging employees to take a more proactive approach to their health. The program supports annual screenings, healthier lifestyle choices, physical activity through a subscription-based wellness platform, and access to caregiver resources. We also rolled out Empathy, a terminal illness and loss support vendor that provides tools for caregivers navigating the challenges of loss or a loved one’s terminal illness. For our efforts to advance employee wellbeing, BBH earned the Business Group on Health’s 2025 Best Employers: Excellence in Health & Well-being award.

Reinforcing our commitment to developing BBHers’ skills, we expanded our investment in leadership capabilities across the company. We piloted a cross-cultural development program in Krakow and Hong Kong to equip early-career managers with the skills needed to thrive in a global workplace. Through interactive sessions, participants explored how to communicate across cultures and become more effective leaders in diverse environments. We also launched an immersive leadership experience for Managing Directors, equipping them with the tools they need to lead with intention, inspire trust, and strengthen connections across the organization.

Additionally, we designed a training program for team managers to further develop leadership capabilities, emphasizing relationship building and accountability to enhance individual and team performance. Giving back to the communities where we live and work has long been embedded into who we are as a company. In 2025, we continued making a meaningful impact by contributing $4.2 million in community giving and over 3,234 volunteer hours to 171 charitable organizations that BBH partners with globally.

THE ROAD AHEAD

We continue to monitor the rapidly evolving sustainability landscape to understand how sustainability issues impact our stakeholders and create risks and opportunities for BBH. We intend to honor the commitments that we have made through our Sustainable BBH program. In doing so, we strengthen trust, manage risk, and position BBH to deliver lasting value for our clients, our employees, and the communities we serve, today and long into the future. I am proud of the work we are doing at BBH and look forward to building on this momentum in 2026.

Sincerely,

William Tyree
