Our Reporting Principles

We have consistently been a leader in transparent reporting on financially material and comparable sustainability and impact (S&I) metrics. In fact, we were the first U.S. public company to report the avoided emissions associated with each of our investments using our proprietary CarbonCount® metric.

Guided by the concept of double materiality, we assess both the impact of environmental and social factors on financial performance as well as the impact of financial decisions on environmental and social outcomes. Our S&I reporting reflects both, offering stakeholders a clear and balanced view of HASI's impact.

HOW WE
INTEGRATE

Governance That Reflects Our Values

Our Board of Directors oversees the adoption of our Sustainability and Impact (S&I) policies and monitors related risks and opportunities. The Nominating, Governance and Corporate Responsibility Committee (NGCR) plays a central role by reviewing our strategies, activities, policies, and disclosures on a quarterly basis.

This review covers key documents, including the Sustainability Investment Policy, Environmental Policies, Code of Business Conduct and Ethics, Human Rights Statement, and Human Capital Management Policies. Through this robust governance framework, we reaffirm our commitment to strong S&I oversight and alignment with our long-term business objectives.

In addition to delivering superior risk-adjusted returns, our investment strategy inherently delivers positive sustainability and impact outcomes. For over a decade as a public company, we have consistently demonstrated that investments in climate positive and energy transition infrastructure drive both long-term value for shareholders as well as a brighter tomorrow for future generations.
