S03 E07 – How impact shapes investment with Adam Gillett, head of sustainable investment at Railpen

18 June 2025
In the latest episode of The Professional Investment Podcast, Adam Gillett, head of sustainable investment at Railpen, and I discuss the results of Responsible Investor’s annual nature and investors survey.

Adam highlights three findings – that nature is important to a high proportion of investors, it’s of equal importance to investors in both the US and Europe and a significant number of investors believe they can make an impact.

We discussed Railpen’s approach to impact and stewardship talking about finding key themes every five years. Even a scheme with 350,000 members and assets under management of £34bn does not have the resource to pursue every issue so priorities must be set.

But there is little point in setting goals unless they can be integrated across different asset classes. Adam discussed how Railpen takes different approach according to the asset class and – in the case of equities – according to actively managed and quantitative portfolios.

While we both welcomed investors’ positive attitude to making impact, Adam underscored the importance of investors engaging with policy makers to create the right legislation for sustainability. That includes working with companies to encourage them to campaign.

This is a must-listen episode for anyone looking to understand how a large UK pension scheme thinks about sustainability, impact and stewardship and why this a fundamental investment principle.
