UK pension scheme fiduciary managers are making incremental progress on ESG integration rather than delivering a step change in investment governance, according to EY’s latest assessment of the market.
The sixth annual report on ESG reporting and governance for fiduciary managers assessed 14 fiduciary managers representing £250bn in assets under management. EY described progress as “evolution rather than revolution”, suggesting the market continues to mature but remains short of a fully transformed approach.
The findings are relevant to trustees, employers, finance directors, and investment committees because fiduciary management is used by pension schemes to delegate day-to-day investment decisions while retaining governance responsibility. ESG integration therefore affects not only asset allocation, but also oversight, reporting, stewardship, and long-term risk management.
Pension schemes sit between multiple pressures. Trustees need to manage returns, funding positions, employer covenant, member outcomes, climate risk, biodiversity, stewardship expectations, and regulatory duties. Fiduciary managers are expected to help schemes navigate that complexity, but the quality and consistency of ESG integration varies across providers.
The pace of progress is being tested as sustainability in finance becomes more contested and more technical. The early phase of ESG investing was often framed around broad commitments, exclusions, and net zero statements. The next phase is more demanding, with investors seeking evidence that ESG factors are being assessed, priced, monitored, and connected to financial outcomes.
That demand for evidence is also visible in carbon markets, where new infrastructure is developing as integrity pressure rises. Pension investment faces a similar discipline. The market is not short of sustainability commitments; it is short of consistent proof that those commitments are being translated into robust decision-making.
For fiduciary managers, integration means more than adding ESG commentary to quarterly reports. It requires evidence that sustainability risks and opportunities influence manager selection, portfolio construction, stewardship priorities, risk models, scenario analysis, and engagement with underlying asset managers.
Trustees are likely to demand more granular reporting as schemes mature. They need to understand how fiduciary managers assess climate transition risk, physical risk, governance standards, human rights exposure, biodiversity, and stewardship escalation. Where reporting is too generic, trustees may struggle to demonstrate effective oversight.
The gradual pace of progress may reflect the complexity of the task. Pension portfolios are diversified across equities, credit, private markets, property, infrastructure, liability-driven investment, and cash. ESG data quality differs sharply between asset classes and geographies. Some risks are material over long horizons, while others can affect valuations quickly.
The market is also navigating political and regulatory tension. In some jurisdictions, ESG is facing backlash; in others, regulators are tightening disclosure and anti-greenwashing standards. UK schemes must avoid treating ESG either as a branding exercise or as a purely ethical overlay. The more durable approach is to show how financially material sustainability factors are governed within investment decisions.
Employers have a stake in the issue. Pension governance affects employee benefits, balance sheet exposure, risk reputation, and workforce trust. Large employers may also face questions from employees about whether retirement savings are aligned with climate, social, or governance expectations. Poor disclosure can weaken confidence even where investment processes are improving.
The findings also raise questions about the relationship between trustees and advisers. Delegation can improve execution and access to specialist capability, but it cannot remove accountability. Trustees need enough information, training, and challenge to evaluate whether fiduciary managers are making meaningful progress rather than simply following market language.
The strongest schemes are likely to move beyond broad ESG ambition towards clearer objectives, measurable expectations, and evidence-based provider review. That may include asking fiduciary managers how ESG affects buy, hold, sell, and engage decisions, how stewardship outcomes are tracked, and how data limitations are handled.
Incremental progress is not insignificant in a market where governance change can be slow. The risk is that incrementalism becomes complacency. Pension schemes operate over decades, but climate, social, and governance risks are already influencing asset values, regulation, and public scrutiny. Fiduciary managers that can show disciplined integration will be better placed as trustees demand greater accountability.
