External benchmarking

We believe that it is important to evidence our commitment to operating sustainably and responsibly and to show how we are performing.

Sustainability indices

We have been a member the FTSE4Good Index Series since 2011. In addition, 3i became a member of the Ethibel Sustainability Index (‘ESI’) Excellence Europe in September 2016 and was reconfirmed as a constituent of that index in May 2020.


CDP (formerly Carbon Disclosure Project) is an international, not-for-profit organisation providing a framework which enables businesses to disclose their greenhouse gas emissions and other metrics voluntarily. 3i has been making annual submissions to CDP since 2006.

ESG Transparency – a Private Equity Index

3i ranked as the top performer in Orbis Advisory and ITPEnergised’s first annual transparency index analysing 160 private equity firms’ ESG reporting performance, based on public disclosures.

UN Principles of Responsible Investment

Since 2011, we have been signatories to the UN Principles for Responsible Investment.

3i’s scores for the 2020 UNPRI assessment report were A for Strategy and Governance, and A+ for both Private Equity and Infrastructure.
