Sustainable, Responsible &/or ESG Policy:
US Solar Fund ('USF', 'the Company') embodies a proactive approach to address climate change and promote sustainable resource management. The Company’s investment focus lies in solar energy investment, aligning its business with the imperative, and financial opportunity, to reduce carbon emissions and foster a cleaner economy.
As at 31 December 2025, USF has a portfolio of 41 assets with a combined capacity of 443 MWDC in solar generation. This substantial capacity translated into tangible environmental benefits, as the Company’s efforts displaced over 434,100 metric tonnes of CO2e emissions for the year. Such a reduction is equivalent to the annual emissions of over 103,400 passenger vehicles or the energy consumption of approximately 65,600 households in the United States.
Furthermore, USF’s commitment to sustainability extends beyond its investment activities. The Company places an emphasis on conducting its operations in a responsible and environmentally conscious manner. It actively engages with local communities to strive for positive impacts and maintains transparent communication with stakeholders regarding its environmental footprint and societal contributions.
The Company supports the 2030 Agenda for Sustainable Development adopted by the UN Member States in 2015. Alignment with the UN Sustainable Development Goals ('SDGs') is a key part of the Company’s approach to Environmental, Social and Governance (‘ESG’) integration. The Company contributes towards the SDGs in two main ways; the positive environmental and social characteristics of its investments and its approach to active asset management.
Process:
Since 1 December 2023, the Company has been managed by Amber Infrastructure Investment Advisor, LLC (AIIA or the Investment Manager), part of the Amber Infrastructure Group (Amber), a Boyd Watterson Global Company. USF has not made any new investments since this date, however the Investment Manager’s approach to ESG integration across the investment lifecycle applies to USF, and includes the following key stages where applicable:
- Research and Innovation
Amber Infrastructure Investment Advisor, LLC (AIIA or the Investment Manager), undertakes targeted research that examines the potential for new investment opportunities.
- Screening
All investments are initially screened against the Investment Manager’s exclusion criteria, and for any ESG ‘red flags’.
- Due Diligence
The Investment Manager undertakes a bespoke due diligence on all potential investments, guided by the investment’s location, asset type and risk profile. Where applicable, the Investment Manager’s deal teams work closely with its dedicated ESG team to develop comprehensive ESG due diligence scopes to ensure ESG risks and opportunities are considered prior to investment. Any items that require addressing post-investment are built into Environmental and Social Action Plans.
- Execution
USF seeks to build ESG clauses into documentation with its investments, including Environmental and Social Action Plans that are prepared at the due diligence stage. This incorporates any actions required to ensure environmental and social safeguarding.
- Active Management
Where applicable, the Investment Manager’s specialist asset management teams monitor the delivery of Environmental and Social Action plans and other agreed targets. ESG Key Performance Indicators (‘KPIs’) and risks are incorporated into reporting, risk management systems and objectives.
- Monitoring and Reporting
The Investment Manager’s asset management team is responsible for monitoring assets and reporting to the Company’s Investment Adviser’s ESG Steering Committee. This process covers a comprehensive set of ESG data, including Principal Adverse Impact indicators, aligned with the definitions set out in Annex 1 of the Regulatory Technical Standards (‘RTS’) under the Sustainable Finance Disclosure Regulation (‘SFDR’).
- Exit
While ESG considerations are considered through the entire lifecycle for USF, to the eventual exit from the investment, the Investment Manager aims to enhance value by ensuring investments are on a sustainable pathway, in line with recognised performance standards and business case assumptions.
Resources, Affiliations & Corporate Strategies:
Amber Infrastructure Investment Advisor, LLC (Amber or the Investment Manager), is responsible for implementing USF’s ESG policies within its day-to-day activities. This includes the integration of ESG considerations through investment origination and management of USF’s investments.
Amber’s Executive Committee is responsible for the stewardship of its business and affairs. The Executive Committee discharges its sustainability responsibilities directly through its internal Risk Committee, ESG Steering Committee, and Diversity and Inclusion Subcommittee. The ESG Steering Committee is chaired by its Chief Operating Officer. The Committee’s primary role is to integrate and strengthen its ESG considerations within investment and asset management activities at a corporate level. The Investment Adviser is supported by a dedicated ESG team.
The Investment Manager has two dedicated ESG employees, including a Head of ESG with 20+ years’ experience and an ESG Analyst with 10+ years’ experience. The team works exclusively on integrating ESG across the investment lifecycle.
Amber utilises various frameworks and benchmarks to guide our approach to investment and asset management. These include:
UN SDGs
Amber believes that by investing in infrastructure that supports a sustainable, prosperous, equitable and resilient society, we will maintain robust financial performance for our shareholders and fund investors. Amber is supportive of the 2030 Agenda for Sustainable Development adopted by the UN Member States in 2015. Alongside our own research into emerging trends and technologies, we draw on the SDGs to help guide our approach to sustainability
UN PRI
To benchmark our ESG integration performance, Amber became a signatory of the UN PRI in 2019. All investment-related activities by Amber are in line with commitments to the Principles, which includes all activities relating to the funds it manages. Amber has received 5* for the Strategy and Governance, and Infrastructure modules each year since it first became a signatory.
TCFD
Climate change presents both transitional and physical risks and opportunities for Amber’s business and investments. As such, it continues to be a high priority for Amber. Amber’s Executive Committee resolved support the recommendations of the Taskforce on Climate-related Financial Disclosure (‘TCFD’), and implements TCFD reporting on the funds it manages
TNFD
Amber is a member of the forum for the Taskforce on Nature-related Financial Disclosures (TNFD).
Paris Agreement
To tackle climate change and its negative impacts, world leaders at the UN Climate Change Conference (COP21) in Paris reached a breakthrough on 12 December 2015: the historic Paris Agreement. Amber is a supporter of the Objectives of the Paris Agreement. This means Amber aims for its investments to either directly, or have the potential to, support climate action.
