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 of 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.

3i’s score in the 2020 CDP assessment is B.

Tortoise Responsibility Index

The Responsibility100 Index is a ranking of the FTSE 100 companies on their commitment to key social, environmental and ethical objectives, inspired by the UN Sustainable Development Goals.

3i ranked 32nd in the March 2020 release of the Responsibility100 Index.

UN Principles of Responsible Investment

Since 2011, we have been signatories to the UN Principles for Responsible Investment. For more than a decade, we have been investing under a clear and comprehensive Responsible Investment policy which is embedded into our investment and portfolio monitoring processes.
