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

Nest is a defined contribution pension scheme in the UK that manages assets of more than £21.4 billion on behalf of 11.1 million members, who make up a third of the UK workforce. It was set up by the UK government in 2010 to support its programme for auto-enrolment into pensions in the workplace.

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.

In 2017, Dame Elizabeth Corley, Chair of the Impact Investing Institute, convened the first meeting of the Taskforce for Growing a Culture of Social Impact Investing in the UK. Since then, the impact investing market has developed significantly – but until now there has not been an estimate of the size of the UK market in its totality. Our report, “Estimating and describing the UK impact investing market”, published in partnership with EY and supported by the Department for Digital, Media, Culture and Sport and Big Society Capital, sets out to change this.

In October 2021, the Department for Work and Pensions launched their consultation “Climate and investment reporting: setting expectations and empowering savers.” We welcome this timely consultation which introduces important and valuable new ways for pension schemes to invest lawfully, responsibly and with impact. We believe, however, that further steps can be taken by the Department to remove existing barriers to impact investing and ensure that the transition to Net Zero benefits the communities most affected by it.

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.

News & Views

Fiduciary duty is not incompatible with impact investment – but, unfortunately, this remains a pervasive misconception. Now, with the publication of the judgement in the case of Butler-Sloss v Charity Commission, a decisive step has been taken towards dispelling this myth for good in the £72bn UK charitable foundation sector. 

All war, wherever in the world it takes place, imposes huge costs and suffering, particularly on civilians. At this time, the Impact Investing Institute shares the world’s horror at the events unfolding in Ukraine and the suffering the invasion by Russia’s armed forces has brought to everybody in Ukraine.

The Impact Investing Institute welcomes the publication of the landmark Levelling Up White Paper and the ambitious, new approach it sets out, designed to re-focus Government spending on tackling place-based inequalities.
