Sustainability Leadership & Impact

Our Approach to Sustainability

Since 2013, we have embedded purpose into our corporate vision: Every investment improves our climate future. Integrating this purpose into our business model allows us to quantify both downside exposure and upside opportunities – all in support of delivering meaningful long-term value and impact.

Our thoughtful and rigorous approach to sustainability and impact embraces the concept of double materiality, focusing on both issues most material to our business and those externalities our business most impacts.

Diversity, Equity, Inclusion, Justice, and Anti-Racism (DEIJA)

Mission Statement

HASI’s recognition of the importance of diversity, equity, inclusion, justice and anti-racism are essential to the success of our business. Our company is more than just the sum of individual roles, skills, and productivities. We are also a team that values the mutually reinforcing empowerment of people of all races, culture, identities, gender expressions, sexual orientations and learning and engagement styles. By opening ourselves to the broadest range of talent, we improve both our company performance and our ability to attract and retain talent. We know it is inherently the right way to conduct business.

Strategic Implementation

Our comprehensive, values-driven approach to diversity, inclusion, equity, justice and anti-racism comprises initiatives that aim beyond legal compliance, to foster an innovative, creative culture where every member of our team can bring their best and most authentic selves to work. We incorporate our efforts throughout all levels of our organization by:

  • Informing our management training efforts through the work of the DEIJA Working Group to ensure they include, but are not limited to, a focus on multicultural leadership, understanding bias and anti-racism
  • Supporting consistent conversations within our team and facilitated by outside experts to better learn from and understand our different respective experiences and perspectives
  • Actively expanding the sourcing of our candidate pool to increase the breadth of its diversity
  • Challenging our business partners to share our DEIJA values and practices
  • Tracking, analyzing and furthering employee pay equity
  • Ensuring our philanthropic efforts consider all views on how to address the intersection of climate and equity
  • Regularly reviewing existing company policies and practices to make updates where and as needed to align our actions with our values
  • Consistently engaging on a corporate level in the protection of voting rights to support a vibrant democracy

Board Oversight

In accordance with its charter, the Nominating, Governance and Corporate Responsibility Committee (NGCR) of our Board of Directors supervises all matters related to DEIJA, including identifying and vetting Director candidates (in anticipation of vacancies), helping formulate the company’s DEIJA strategy and monitoring DEIJA performance metrics. The NGCR Committee meets at least quarterly to provide oversight, field updates and inform the DEIJA strategy’s overall direction. In addition, the Committee’s Chair periodically participates in meetings with investors particularly concerned with DEIJA-related topics.

  • 82% Independent
  • 36% Female
  • 18% Racial or Ethnic Minority

Climate Justice

In early 2022, we adopted an organizational Climate Justice Statement to affirm our commitment to advancing social justice in tandem with our mission of investing in climate solutions.


Principles of Governance

The Board of Directors works directly with our CEO, who guides the company’s operations, which are executed by our officers and employees. Our Board comprises 11 members, 82% of whom are independent, elected annually by our shareholders.

At HASI, we acknowledge the significance of considering, assessing, and tracking sustainability and impact-related opportunities and risks as part of our broader vision and strategy. The Nominating, Governance and Corporate Responsibility Committee (NGCR) plays a vital role in regularly reviewing our strategies, activities, and policies, including our Sustainability Investment Policy, Environmental Policies, Code of Business Conduct and Ethics, Human Rights Statement, and Human Capital Management Policies. This sustainability and impact governance structure ensures that we remain aligned with our sustainability and impact goals and objectives.

Giving Back

The HASI Foundation was created to add a long-term strategic lens to our maturing corporate philanthropy efforts targeted at the intersection of climate action and social justice. This effort flowed from an organic expression of shared values that fits naturally within our culture of fierce curiosity and rigor about outcomes in climate investing.

The foundation is funded by annual Social Dividends declared by HASI and the proceeds from an internal price on carbon assessed against HASI’s Scope 1, 2 and 3 emissions (net of the avoided emissions resulting from investments). Over the last three years, HASI has contributed nearly $4.5 million to the foundation.


We seek to accelerate a just transition toward an equitable, inclusive and climate positive future.
