ESG Approach, Impact & Policies

Our Approach

At Hannon Armstrong, we have historically and consistently aspired to be a leader in transparent reporting on financially material and comparable ESG metrics. We hope our reporting on many of these and other recommended metrics helps to drive transparency and alignment among companies, investors, and all other stakeholders – with the ultimate goal of building a more sustainable and inclusive global economy.

We were the first U.S. public company to report the avoided emissions resulting from our investments – a disclosure most financial service companies and asset managers still neglect to provide – and one of the first to adopt reporting in accordance with the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD) and to incorporate TCFD reporting into our SEC filings.

To help reduce fragmentation and accelerate progress toward a generally accepted ESG standard in alignment with the UN Sustainable Development Goals (SDGs), our 2020 Impact Report has been designed around the four pillars of the common metrics for consistent reporting of sustainable value creation as developed by the World Economic Forum’s International Business Council: Principles of Governance, Planet, People, and Prosperity.

Sustainable Development Goals

Diversity, Equity, Inclusion, and Justice (DEIJ)


At Hannon Armstrong, we believe that our company is more than just the sum of individual roles, skills, and productivities. In addition, we recognize that fostering a supportive climate that allows people of all backgrounds to flourish lends itself to the highest levels of company performance and facilitates the attraction and retention of best-in-class talent.

We also believe it is inherently the right way to conduct business. As a result, we take a comprehensive, values-driven approach to diversity, inclusion, equity, and justice.

Board Oversight

In accordance with its charter, the Nominating, Governance and Corporate Responsibility Committee (NGCR) of our Board of Directors is responsible for oversight of all matters related to DEIJ, including identifying and vetting Director candidates (when vacancies arise), helping to formulate the company’s DEIJ strategy, and monitoring DEIJ performance metrics.

Comprehensive Plan for Multiyear Impact

In 2020, we engaged an independent DEIJ consultant and convened an internal DEIJ Working Group to identify specific DEIJ challenges facing our organization and develop a multiyear plan for addressing them.

Key components of this plan include the below. We hope to provide more information on our progress on these initiatives in next year’s report.

  • Talent Acquisition
  • Business Resource Groups
  • New Employee Onboarding
  • Training and Professional Development
  • Dashboard Metrics
  • Human Resource Process Amendments
  • 89% Independent Board Members
  • 33% Women Board Members
  • 11% Racial or Ethnic Minority Board Members

Goals and Metrics

Fundamentally, we aspire to the goal that our employees at each level of our organization are representative of the communities in which we operate. To this end, we have begun to track and report internally on key talent metrics including workforce demographics, critical role pipeline and diversity data, and engagement and inclusion indices.

Further, we are committed to identifying and developing the talents of our next generation of leaders and better support our female and underrepresented employees in their onboarding, training, development, and progression within the Company.

We remain committed to “equal pay for equal work” in compliance with applicable state law. To validate our commitment, we have engaged an independent firm to conduct a pay equity audit. We expect to provide additional disclosures around the outcome of this audit upon its conclusion.


Principles of Governance

Internally managed, the business affairs of our company are conducted by our officers and employees under the direction of our President & CEO with the oversight of our Board. Our Board members – eight of whom are Independent – are elected annually by our stockholders.

We recognize the importance of understanding, evaluating, and monitoring ESG-related opportunities and risks as part of our vision and strategy. The Nominating, Governance, and Corporate Responsibility Committee (NGCR) is responsible for periodically reviewing our strategies, activities, and policies including our Sustainability Investment Policy, Environmental Policies, and Human Rights and Human Capital Management Policies.

Corporate Foundation

We created the Hannon Armstrong Foundation in early 2021 to add a strategic, long-term lens to our maturing corporate philanthropy efforts – tied to specific focus areas and committed to impact measurement. This flowed from an organic expression of shared values that fits naturally within our culture of fierce curiosity and rigor about outcomes in climate investing. In early 2021, we declared an initial “Social Dividend” to the foundation of $1 million.


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