The TSWG is chaired by HS Trustees' Bobby Riddaway
The Trustee Sustainability Working Group (TSWG) has set out its key objectives for the year ahead.
The group – chaired by HS Trustees managing director Bobby Riddaway – was formed by a group of 13 professional and member-nominated trustees at the end of 2024 in a bid to accelerate the implementation of good sustainability investment practice across the industry.
The TSWG said climate change would continue to be a key focus of the group – noting that, during 2025, it spent its time developing conversations with trustees, consultants, regulators and policymakers, among others, and was now ready to go into 2026 "determined to drive change".
The group said its 2026 priorities are:
1. Proportional and purposeful sustainability reporting: Refining the reporting to ensure it remains proportionate to each scheme and practical to implement. The TSWG said its focus is on transforming reporting from a compliance requirement into a meaningful driver for positive impact.
2. Bridging the perception gap: The TSWG said demonstrating that sustainable investment is a financially sound, practical strategy that serves the best long-term interests of pension members. It said that, currently, an estimated 70% to 80% of trustees and consultants view sustainability as a "tick-box" exercise.
3. Scalable solutions for all schemes: The TSWG also said it wants to help provide practical solutions that dismantle the myth that sustainable investing is only for large-scale funds. The group said it is cooperating across the investment ecosystem to ensure that schemes of all sizes can move beyond simple reporting compliance and participate with purpose in the transition to a sustainable future.
