Our goal

We aim to make it easier for pension schemes to invest with impact. We help them reduce negative impacts and risks like carbon emissions, biodiversity loss, poor governance and inequality that arise from their portfolio. One of the Institute’s top priorities is debunking the myth that impact investing means sacrificing financial returns. We have also demonstrated that an impact approach is entirely compatible with pension trustees’ and advisors’ fiduciary duties.

What we are doing to achieve it

We are working across the pensions industry – with pension schemes, investment consultants, asset managers, policy makers, lawyers and industry experts – to debunk some common myths about impact investing. The most common misconception among pension trustees and advisors, who are understandably concerned about their fiduciary duties, is that impact investing means sacrificing financial returns.

Fiduciary duty is not a barrier to impact investing

To address the common myth that impact investing is at odds with pension trustees’ fiduciary duty – the legal obligation on trustees to act in the best interest of the scheme’s members – we produced a legal paper that explains how fiduciary duty and impact investing are compatible. The paper was written and attested by five leading law firms.

We also produced a short explainer video debunking some of the most common misconceptions about impact investing with the generous sponsorship of Barnett Waddingham.

Practical principles to empower pensions to invest with impact

Together with leading practitioners from across the pensions sector, we have developed four Impact Investing Principles for Pensions. They are a practical guide to impact investing and provide four concrete steps pension schemes can take to pursue an impact investing strategy.

In partnership with Pensions for Purpose, we run the Adopters Forum – a member forum of pension schemes, investment consultants and fiduciary managers that have committed to the Impact Investing Principles for Pensions. Current members have over £16.8 billion in assets.

We have also published case study examples of pension funds that are already successfully integrating impact into their investment decisions to help others do the same.

How were the Principles designed?

The Principles were designed and tested through consultation with people across the pensions industry, in partnership with Pensions for Purpose.

The Principles offer a good governance framework that accompanies the investment process at every stage in the investment chain. It explains elements such as: how pension schemes can put in place objectives and establish an implementation framework; how to hold investment consultants and managers to account; as well as how to report on what is being achieved through a balanced measurement framework.

Who can use the Principles?

The Principles are designed to be used by trustees, local government pension scheme (LGPS) committee members, advisers and in-house investment teams across the full spectrum of pension schemes.

They are also a useful tool for investment consultants, fiduciary managers and asset managers working with clients.

Case studies

Clwyd Pension Fund is one of the 89 local funds that form the Local Government Pension Scheme in England and Wales. Representing 52 employers, they have a total of 48,800 members and manage assets of £2.3 billion.

The Greater Manchester Property Venture Fund (GMPVF) was created by the Greater Manchester Pension Fund in 1990. It is a specialised vehicle for the LGPF to invest in property developments in Greater Manchester and across the wider North West area which generate a commercially viable rate of return.

South Yorkshire Pensions Authority is responsible for administering the Local Government Pension Scheme in South Yorkshire. With over 166,000 members, they represent 533 employers and manage assets of £9.9 billion. Alongside adopting the Impact Investing Principles for Pensions, they are aiming for a 5% allocation to impact investments and to achieve net zero by 2030.


In partnership with Property Funds Research and supported by Homes England and Investment Property Forum, we have published a ground-breaking and comprehensive report detailing the investment case for UK social housing.

In June 2021, the Institute submitted its response to the Department for Work and Pensions’ consultation on the consideration of social risks and opportunities by occupational pension schemes. The Institute strongly welcomes the consultation’s foresight in recognising the increasing importance of social factors for investing.

In our first impact report for 2019-20, we are reflecting on our achievements of our first year and are looking ahead to how we can work towards our goal of improving people’s lives, as more capital contributes to addressing social and environmental challenges.

Learning Hub modules

Private capital, including pension money, can address place-based inequalities across the UK and secure financial returns at the same time. This module explores how.

Place-based impact investments are made with the intention to yield appropriate risk-adjusted financial returns as well as positive local impact, with a focus on addressing the needs of specific places to enhance local economic resilience, prosperity and sustainable development.

Local government pension funds have a legacy and interest in local investing. If 5% of LGPS funds were allocated to local investment this would unlock £16 billion for place-based impact investing, more than matching public investment in levelling up.
