Stuart O'Brien

Stuart O’Brien at Sacker & Partners LLP is highly sought-after for his wealth of expertise on the engagement of the pensions sector with sustainable development, climate risk, and nature.

As a core focus of his practice, O’Brien assists pension schemes with identifying, reporting on, and building strategies surrounding ESG-related risks and opportunities.

O’Brien was a founding member of a cross-industry group which proposed an amendment to the Pension Schemes Bill to clarify the sector’s investment fiduciary duties. The group brought together sustainability-focused organisations such as the Impact Investing Institute and ClientEarth, as well as stakeholders in the investment and pensions sectors, to navigate how pension schemes can account for systemic climate risk and unlock domestic investment.
