Master trust pensions lag in climate solutions investment
Master trusts embrace net zero targets but capital still flows elsewhere
UK master trusts are setting ambitious climate goals on paper. However, a recent XPS analysis reveals that most still prioritise cutting portfolio emissions rather than funding the climate solutions needed for the net zero transition. The gap is significant because pension schemes hold more than £200 billion in the 16 master trusts examined. Consequently, failure to shift capital could affect both long-term saver outcomes and the pace of decarbonisation across the economy.
This pattern highlights a recurring issue in pensions. Many schemes have adopted decarbonisation goals, yet fewer have set out how they will channel capital into low-carbon technologies, infrastructure, and industries. For pension savers, the question is no longer whether schemes talk about net zero. It is whether they are using their scale to help fund the transition in a measurable way.
The broader policy context suggests this challenge sits within a wider shift in UK pension regulation. Climate governance is now mainstream at the master trust level. Nevertheless, governance alone does not guarantee that capital flows into the projects and sectors that will deliver decarbonisation at scale.
Half of schemes lack clear climate solutions focus
XPS reviewed 16 defined contribution master trusts with more than £200 billion in assets. The analysis found that 15 had an objective aligned with net zero or the Paris Agreement. Despite this, only 50% had a clear focus on investing in climate solutions. In other words, most schemes have adopted decarbonisation goals, but fewer have defined how they will back clean energy, sustainable transport, or low-carbon infrastructure.
This distinction matters. Reducing portfolio emissions can be achieved by selling high-emitting assets or tilting towards lower-carbon indices. However, that does not automatically increase real-economy climate investment. The XPS findings suggest the sector is still better at managing exposure than at financing solutions.
Meanwhile, UK government guidance on green pensions defines environmentally sustainable pensions as those with a net zero commitment and investments in climate change solutions such as clean energy. The same guidance says low-touch communications alone are unlikely to drive meaningful change in pension environmental impact. Therefore, schemes need to move beyond policy statements and into tangible allocation decisions.
Industry commentary from Standard Life is consistent with that picture. The company says pension investment in climate solutions remains limited by a lack of scalable opportunities and regulatory constraints. At the same time, it argues that the UK sector could substantially expand such investment if reforms improve the pipeline of viable projects.
Regulator confirms climate governance is widespread but action varies
The Pensions Regulator's climate adaptation report for 2025 says all master trusts in its sample had allocated time or resources to climate-related risks and opportunities. This shows that climate governance is now embedded at the master trust level. Furthermore, more than 60% of the pension scheme reports the regulator reviewed had some form of net zero goal with a 2050-or-earlier target date.
Practical steps are also underway. Schemes are training trustees, asking managers about climate factors, and increasing allocations to sustainable or low-carbon funds. However, those actions do not necessarily translate into direct investment in climate solutions at scale. Governance frameworks and fund labels are important, but they are not the same as financing renewable generation, grid infrastructure, or clean manufacturing capacity.
The regulator's findings suggest that master trusts have made progress on climate risk identification and disclosure. Nevertheless, the shift from risk management to transition financing is still incomplete. Consequently, many schemes are well positioned to understand climate risks but less advanced in using their capital to drive real-economy change.
What this means for pension savers and net zero delivery
The significance of these findings is that climate ambition in pensions is shifting from pledges to implementation. Many master trusts now acknowledge net zero, but fewer have defined how to invest in the economy that will deliver it. This matters because pensions are long-term capital pools, and long-duration assets are well suited to financing renewables, clean transport, grid upgrades, and other transition infrastructure.
For savers, the issue is practical. XPS warned that failure to adapt investment strategies could affect retirement outcomes. Specifically, insufficient climate alignment may hit DC members' savings and expose them to sequencing risk as the economy shifts towards decarbonisation. Therefore, the way schemes allocate capital today could influence the value of retirement pots decades from now.
There is also a wider economic implication. Pension schemes are among the largest pools of patient capital in the UK. If they prioritise emissions reduction over climate solutions investment, the gap between targets and capital availability grows. As a result, the UK may struggle to finance the infrastructure needed to meet its own net zero commitments.
Moreover, the policy tension is clear. Selling high-emitting assets reduces a portfolio's carbon footprint on paper. However, it does not create new wind farms, solar plants, or battery storage facilities. Real-economy decarbonisation requires someone to own and finance those assets. Pension schemes are well placed to do that, but only if they shift from divestment to deployment.
Some schemes are moving faster than others
Tony Burdon of Make My Money Matter said that whilst it is good to see some providers like Nest, Now, and Smart improving their policies on climate and nature, others like Standard Life and Royal London continue to fail their savers. This suggests that the gap between leading and lagging schemes is widening. Consequently, savers may need to consider which master trust their employer uses and whether its climate strategy goes beyond headline commitments.
The variation also highlights a broader challenge. Master trusts serve millions of savers, often through workplace pensions where individuals have limited control over investment choices. Therefore, the quality of climate strategy at the scheme level can have a significant impact on outcomes, even for savers who are engaged with sustainability issues.
Furthermore, as climate risks become more material, the performance gap between schemes that finance solutions and those that simply divest may widen. Schemes that back the transition could benefit from exposure to growing sectors. Those that focus only on emissions reduction may miss those opportunities.
Key facts about master trust climate strategies
- XPS analysed 16 defined contribution master trusts representing more than £200 billion in assets.
- Fifteen of those trusts had an objective aligned with net zero or the Paris Agreement.
- Only 50% had a clear focus on investing in climate solutions.
- The Pensions Regulator found all master trusts in its climate sample had allocated time or resources to climate risks and opportunities.
- More than 60% of the reports in the regulator's sample had a net zero goal with a 2050-or-earlier target date.
- Practical steps include training trustees, asking managers about climate factors, and increasing allocations to sustainable funds.
What businesses and savers should consider
For employers selecting or reviewing master trust arrangements, the XPS analysis suggests that climate ambition is now table stakes. However, the quality of climate strategy varies significantly. Therefore, it is worth asking whether a scheme has a clear plan to invest in climate solutions, not just reduce emissions on paper. This distinction could affect both member outcomes and alignment with corporate sustainability commitments.
Businesses that operate workplace pensions may also face questions from employees about how their savings are being invested. Consequently, understanding the climate strategy of your master trust is becoming a governance issue, not just an environmental one. Employers may want to ask for evidence of climate solutions investment, not just net zero pledges.
For SMEs that are themselves navigating net zero targets, the way pension schemes allocate capital could influence the availability of finance for low-carbon projects. If master trusts shift more capital into climate solutions, it could improve access to funding for clean technology, energy efficiency, and sustainable infrastructure. However, if schemes continue to prioritise emissions reduction over investment, the pipeline of available capital may remain constrained.
Additionally, businesses that supply public sector organisations or large corporates may find that their own climate commitments are scrutinised more closely. If your pension scheme is misaligned with your stated sustainability goals, it could create reputational or commercial risk. Therefore, reviewing your master trust's climate strategy is now part of broader ESG governance.
We work with businesses on carbon reporting and net zero compliance, including helping organisations understand how sustainability commitments interact with wider business decisions. Pension scheme alignment is one area where corporate climate goals and employee benefits intersect, and it is an area where clarity is increasingly important.
Where to find further information
The Pensions Regulator publishes annual climate adaptation reports that cover master trust progress on climate governance and risk management. These reports provide detailed insight into how schemes are implementing climate strategies and where gaps remain. You can access them through the regulator's website.
The UK government has also published guidance on green pensions, including definitions of environmentally sustainable pensions and recommendations for scheme communications. This guidance is available on gov.uk and provides a useful framework for assessing whether a scheme's climate strategy is aligned with broader policy expectations.
For employers and savers who want to understand how specific master trusts are performing on climate, the XPS analysis and related reporting from professional pensions media outlets provide benchmarking data and commentary. These sources can help you compare schemes and assess whether climate solutions investment is a priority.
Finally, industry bodies such as the Institute of Environmental Management and Assessment (IEMA) and the Chartered Institute of Personnel and Development (CIPD) publish resources on sustainable pensions and workplace benefits. These can help HR and finance teams integrate climate considerations into pension governance and employee communications.
