Sustainability reporting has expanded well beyond environmental metrics in recent years, with many organisations now reporting on aspects of social sustainability too: workforce wellbeing, fair pay, safe working conditions. One area that appears to get comparatively little attention in that reporting: the pension a company automatically enrols its employees into.

That’s arguably a gap worth closing. A decade of UK pension performance data doesn’t explain why retirement provision gets overlooked in sustainability reporting, but it does show just how much is riding on the choice being overlooked.

The social sustainability blind spot

Social sustainability asks a straightforward question of any employer: are the people working for this organisation genuinely better off because of it, over the long term, not just this quarter? GRI 201: Economic Performance, part of the GRI Standards framework used by organisations worldwide, already provides a disclosure category for exactly this: disclosure 201-3 specifically covers an organisation’s defined benefit plan obligations and other retirement plans. 

In practice, though, retirement provision doesn’t seem to feature as prominently in workforce-focused sustainability commentary as topics like pay equity, health and safety, training, and working conditions, though this piece hasn’t measured that comparison systematically. Whatever the actual balance, retirement outcomes represent a substantial financial commitment that an employer shapes on an employee’s behalf, often without the employee ever choosing it themselves.

There’s a plausible reason for that. Pension performance unfolds over decades, not quarters, which makes it a poor fit for an annual reporting cycle. It’s also technical, and pension selection is often delegated early to procurement or finance functions, though this piece doesn’t have data confirming how common that pattern is across organisations generally. Whether or not that specific explanation holds everywhere, retirement outcomes remain material to an employee’s long-term wellbeing, whether or not they’re easy to capture in a reporting cycle.

The evidence sitting outside most sustainability reports

Here’s the kind of figure that would normally trigger a material disclosure in any other part of a sustainability report. Independent UK research from Corporate Adviser found that, over the 10 years to December 2025, the strongest-performing default pension fund returned 232%, while the weakest managed just 88%. 

Most employees never actively choose which of these funds they end up in, even where the option exists; the default is set by whichever provider their employer selects, so the gap ends up shaping outcomes for people who, in practice, never exercised a choice over the underlying decision. TPT Retirement Solutions was one of the funds included in that comparison, finishing third. 

Their DC Director, Philip Smith, concluded from the data that arguably has relevance beyond the pensions sector itself:

“For a long time, scale and low cost have carried a built-in assumption of safety. Big feels credible. Cheap feels efficient. Both are easy to defend. But member outcomes are what matter, and outcomes like these are a reminder that size and price do not, on their own, define value.”

Consider an employer that reports diligently on carbon intensity, water use, and supply chain labour standards, but has never reviewed whether its own pension default fund is actually performing. Hypothetically, at least, that would leave a real gap in its social sustainability picture, since the employees affected are the same employees any sustainability report is nominally trying to protect.

Bringing pension oversight into scope

None of this requires building out pension selection into a full ESG-style metric. A more modest step would be considering whether a benefit this consequential, and this easy to leave unreviewed for years, deserves a place in an organisation’s broader thinking about employee wellbeing.

A few practical starting points for organisations already reporting on social sustainability:

• Ask when the pension default was last reviewed for performance, not just for compliance or cost. If nobody in the organisation can answer that with a specific date, that’s itself a useful data point.
• Consider treating retirement outcomes as a long-term wellbeing metric, sitting alongside whatever pay equity and working conditions data an organisation already reports.
• Request performance data, not just fee schedules, when evaluating or renewing a pension provider. Cost and brand reputation are the easiest things to compare on a shortlist. The UK data doesn’t tell us whether those two factors correlate with performance one way or another, but it does confirm that performance varies enormously between funds, which is reason enough to ask the question rather than assume cost or brand answers it.

Social sustainability, at its core, is arguably about whether the people an organisation is responsible for end up genuinely better off because of decisions made on their behalf. A pension default fund, chosen once and rarely revisited, looks like exactly that kind of decision, and one worth a place in the conversation.
