Pension Schemes Bill

Baroness Hayman Excerpts

Thursday 18th December 2025 Lords Chamber

[Baroness Hayman (CB)]

My Lords, I declare my interests as a past chair and present director of Peers for the Planet. It is a great pleasure to follow the noble Lord in what he has just said. We have worked together on these issues before, and I feel somehow that on the issue to which I will return, fiduciary duty, we have the very good beginnings of a cross-party amendment with him, me and the noble Baroness, Lady Bowles—and I hope we will recruit from the Labour Benches as well.

The noble Lord, Lord Sharkey, some hours ago—not long hours, interesting hours—mentioned the absence in the Bill of any reference to the Paris Agreement and the Climate Change Act. The noble Baroness, Lady Bennett, mentioned the previous Pension Schemes Bill, in which we both participated six years ago.

That Bill, thanks to a cross-party amendment and great support from the noble Baroness, Lady Stedman-Scott, who was the Minister at the time, included references to the Paris Agreement and the Climate Change Act. I am assured that it was the first piece of pensions legislation in the world that mentioned those things, and it has been followed by many pieces of pensions legislation in many jurisdictions since then. Therefore, I am hopeful that we may make some progress on this.

As the Pensions Regulator has said, pension schemes are

“uniquely placed to understand that short-termism in the face of systemic risk is not the right approach for … pension savers”.

Successive Governments have recognised that the UK’s long-term prosperity will depend on our ability to lead the transition to a greener financial system. However, financial experts, such as the Institute and Faculty of Actuaries and the Pensions Regulator, warn that many schemes continue dramatically to underestimate climate and environmental risks. The Pensions Regulator has stressed that climate change and nature loss are not “abstract concerns” and that

“awareness of and managing systemic risks is … a core part of effective trusteeship”.

The Chancellor recognised the centrality of the issue in her Mansion House speech last year. In letters to the Bank of England and financial regulators, she said:

“The climate and nature crisis is the greatest long-term global challenge that we face”.


She recommended that they

“consider how these risks could impact financial stability over the near and longer-term”.

She also reaffirmed her commitment to make the UK a global leader in sustainable finance.

There are clear benefits to placing the UK at the centre of global financial flows that will drive the economy of the future, creating high-quality jobs and enabling the investment we so urgently need in the face of ongoing economic and cost of living pressures. The pension sector must be central to that endeavour. With the third-largest stock of pension assets in the world, the UK has the capacity to set a global benchmark for responsible investment. The £3 trillion held in UK pensions represents an enormous opportunity to align long-term investment with long-term risks and long-term economic stability.

However, significant exposure to environmental and supply chain risks and fossil fuels leaves savers at risk of holding stranded assets or seeing significant reductions to their pension pots in the years ahead. This is neither in members’ interests nor in our national interests. Therefore, in our discussions on the Bill, I will be very interested to hear how pension schemes investments can align with our climate and nature goals.

As the Bill stands, it remains silent on how the major pension reforms it contains will support the delivery of our nature and net-zero targets, despite the risk to both savers and our economic prosperity that institutions, such as the International Energy Agency and the Climate Change Committee in this country, have highlighted. UKSIF has estimated that approximately £88 billion-worth of UK pensions are directly invested in fossil fuel assets, and that, even if the limited decarbonisation pledges made so far by countries are fulfilled by 2040, £15 billion of UK pensions are at risk of loss due to stranded assets.

The Bill offers a practical, incremental opportunity to put a direction of travel in statute on the need to move away from investment in carbon-intensive assets in a managed and orderly way. It could send a clear signal about the long-term risks we face and help pension schemes to prepare for the transition in a considered way.

One of the measures we could take, and something that I will certainly be focusing on, as I said, as we go through the remaining stages of the Bill, is the clarification of fiduciary duty. For too long, many pension schemes’ trustees have reported confusion about what they should take into account when making investment decisions, particularly when those decisions involve long-term structural risks such as climate change, nature loss and other systemic factors. This can lead to unnecessary and unjustified caution and reinforce a bias towards short-term financial returns, even when the long-term risks are clear.

I think we all absolutely understand and agree that trustees of pensions have a fundamental responsibility to act in their members’ financial interests. However, the clarification of fiduciary duties in legislation, far from detracting from that responsibility, would enable trustees to fulfil it more effectively. So, while I welcome the commitment made on Report in the other place for guidance on this issue to be brought forward, guidance alone falls short of providing the legal certainty that is needed, as the noble Baroness, Lady Bowles, said so clearly.

Guidance can be challenged, ignored, and reversed without primary legislation. The legal ambiguity to which trustees are currently exposed will remain, even if in a slightly lesser degree, if there is only guidance on which to rely. Legislative clarification would dispel that uncertainty and future-proof the system to ensure that pension schemes are better able to recognise and to manage the systemic risks of climate change and nature loss. It would support trustees to act in the long-term interests of all beneficiaries and address issues of intergenerational fairness that are becoming of increasing importance as the longer-term consequence of the climate and nature crisis becomes clearer. It could also lead to better returns and increase new investment in the areas we need to future-proof our economy: clean energy, clean transport, clean infrastructure and, crucially, to unlock the economic opportunity of investing in nature-positive solutions.

I very much look forward to pursuing those issues as the Bill proceeds through your Lordships’ House.
