Long-term, responsible investment

Click here for our 2023 Sustainability Report

We believe that renewable energy is an asset class where it is possible to achieve attractive long-term investment yield whilst making a major contribution to lower global carbon emissions.

For TRIG and its Managers, investing responsibly is essential for us to maintain a sustainable business model over the long term. This goes further than our commitment to reducing carbon emissions through renewables investment but also includes other sustainability considerations.

TRIG has four sustainability goals which the Company and its managers seek to fulfil with every investment we make as we operate our assets and generally conduct ourselves on a day-to-day basis:

  • Mitigate Climate Change
  • Preserve our natural environment
  • Positively impact the communities we work in
  • Maintain ethics and integrity in governance

TRIG’s Investment Manager, InfraRed, maintains a comprehensive sustainability management system which integrates sustainability into each stage of the investment process – starting with the initial assessment of an investment opportunity and running throughout the life of an asset to its decommissioning.

InfraRed takes an active approach to long-term sustainable investment which is based on a foundation of robust ESG principles. InfraRed uses environmental criteria to assess how effectively a company stewards the natural environment, assists with the transition to a low carbon economy and complies with relevant laws and regulations. Through a social set of standards, the team evaluates the company’s approach to health & safety, labour standards and working conditions as well as the relationships it has with its stakeholders and surrounding communities. In terms of corporate governance, InfraRed looks to ensure that our partners adhere to the highest standards of corporate conduct. Regular studies, inspections, surveys and risk assessments are undertaken to ensure this remains the case at all times.

Processes are reviewed and refreshed periodically as part of a commitment to continuous improvement. InfraRed has achieved the highest possible PRI rating¹ for its infrastructure business for seven consecutive assessments, having secured a five-star rating for the 2021 period, demonstrating its longstanding commitment to sustainable investment.

1 Principles for Responsible Investment (“PRI”) ratings are based on following a set of Principles, including incorporating ESG issues into investment analysis, decision-making processes and ownership policies. More information is available at


RES’ sustainability agenda is ‘to power positive change by ensuring that its operations, products and services make a net positive contribution to society and the environment.’ RES has an ESG Policy and Strategy agreed at Group Executive level, and the ESG teams integrate this strategy, measure performance, and communicate sustainability policies and activities to the wider group.

As TRIG’s Operational Manager, overview and management of operational ESG activities are led by RES, who have extensive experience in supporting a variety of ESG frameworks. RES keeps active sight of the Operational KPI’s published in the interim and annual reports, which include energy use, emissions data, habitat management, homes equivalent powered, displaced carbon, Local Electricity Discount Scheme, and community outreach activities. RES strive to keep and maintain health and safety standards on site, good relationships with local communities, and enhanced habitat management.

TRIG’s Board and Managers recognise the importance of regular and transparent reporting. Sustainability reporting promotes better risk management, operational efficiency and ensures that we are accountable to our stakeholders.

InfraRed and RES each report on their sustainability related activities, including relating to climate change. Their reporting is available on their respective websites.

TRIG has four ESG goals which we seek to fulfil with every investment we make and as we conduct ourselves on a day-to-day basis:

  • To mitigate Climate Change
  • To preserve our natural environment
  • To positively impact the communities we work in
  • To maintain ethics and integrity in governance

We periodically report on portfolio progress against these goals with specific Key Performance Indicators, recent disclosures are available on the Reports & publications page here.

TRIG is a supporter of the Task Force on Climate-related Financial Disclosures (“TCFD”), in line with our commitment to SDG 13 Climate Action. TRIG continues to expand its assessment of the potential impact, including opportunities and risks, of climate change and its TCFD reporting, which can also be found in TRIG’s Annual Report.

TRIG remains aligned with European Union and United Kingdom sustainability regulations. Details of TRIG’s SFDR categorisation and results of the EU Taxonomy assessment undertaken on the portfolio can be found in TRIG’s Sustainability Report.

TRIG’s Managers and Board seek to continue to improve TRIG’s sustainability reporting and continue to monitor this evolving area to ensure we adopt market best practices.

TRIG’s Investment Policy only permits investment in renewables and other forms of infrastructure that is complementary to, or supports the roll-out of, renewable energy generation. Reducing greenhouse gas (including carbon) emissions is central to the purpose of TRIG and its Managers.

InfraRed is a member of the Net Zero Asset Managers initiative. RES is also a signatory to the SBTi and offsets their operational emissions, including those associated with electricity usage and business travel. The TRIG Board adopts practices which help to maintain a low carbon footprint, including combining face-to-face meetings with virtual calls where appropriate and not printing Board papers. Emissions associated with the Board’s business travel are offset.
