Decarbonising Heritage: How London Transport Museum is Powering Change in Listed Buildings

Introduction

The London Transport Museum (LTM) has embarked on a transformative journey in recent years to reduce its energy consumption and carbon emissions. Operating two key sites, the main museum in Covent Garden and the Museum Depot in Acton, LTM has leveraged its participation in JB’s Capital Investment Readiness Programme, launched in August 2023, to enhance its decarbonisation efforts. This case study explores LTM’s strategic initiatives, challenges, and future plans as it works toward achieving net zero emissions while preserving its status as a historic listed building.

Background

As a cultural and historical institution, LTM faces unique challenges in balancing its operational needs with environmental sustainability. Its two estates, housed in aging infrastructure, historically relied on energy-intensive systems such as traditional lighting and gas boilers. Recognising the urgency of climate action, LTM joined JB’s programme to strengthen its approach to securing capital investment and implementing decarbonisation strategies. The programme provided tailored coaching, advisory support, and insights into funding opportunities, enabling LTM to align its environmental goals with practical, fundable projects.

Key Initiatives in Recent Years

LTM’s journey towards net zero has been marked by actionable steps to reduce energy use and carbon emissions across its estates:

1. Energy Efficiency Upgrades

• LED Lighting Replacement: At the Covent Garden museum, LTM replaced traditional lights with energy-efficient LEDs, significantly lowering energy consumption. This initiative served as an immediate win, demonstrating the museum’s commitment to sustainability while reducing operational costs.
• Roof and Boiler Assessments: Comprehensive evaluations of the museum’s roof and gas boilers identified critical areas for improvement. The roof project, which includes refurbishing skylights and integrating photovoltaic (PV) panels, is now poised to attract capital funding.

2. Decarbonisation Strategies

• Gas Boiler Replacement Options: LTM conducted cost assessments to replace its gas boilers with heat pumps, a move toward electrification. However, a new opportunity to connect to a heat network has emerged, prompting the museum to weigh both options for optimal decarbonisation. A final decision is expected later in 2025.
• Three Decarbonisation Reports: Commissioned as part of JB’s programme, these reports provided a roadmap for short-term, mid-term, and long-term decarbonisation plans. They prioritise capital investments and assess the condition of existing appliances, guiding LTM’s net zero mission.

3. Future-Ready Plans

• At the Acton Depot, LTM has outlined high-level plans to introduce heat pumps and PV panels while replacing water appliances with low-flow alternatives. These initiatives are part of a major refurbishment project tied to the museum’s 15th anniversary in 2030.

Challenges Faced

Decarbonising a historic listed building presented significant hurdles for LTM. Understanding the full scope of retrofitting ageing infrastructure while adhering to preservation regulations required extensive technical and feasibility studies. Additionally, aligning decarbonisation efforts with evolving funding landscapes and policies posed a strategic challenge. LTM overcame these obstacles by:

• Conducting in-depth research into innovative solutions tailored to listed buildings.
• Engaging stakeholders and potential funders with clear communication about the environmental and operational benefits of its initiatives.
• Leveraging expert guidance from JB’s programme to refine its approach.

Outcomes and Strategic Advancements

LTM’s participation in the JB’s programme has yielded a structured decarbonisation strategy with well-defined priorities. Key outcomes include:

• Enhanced Funding Confidence: By aligning projects with funders’ environmental priorities, LTM has bolstered its ability to secure capital investment for future initiatives.
• A Roadmap to Net Zero: The three decarbonisation reports provide a clear path toward total electrification and sustainable energy integration, with milestones set through 2030.
• Operational Benefits: Early wins, such as LED lighting, have reduced energy costs, freeing up resources for further sustainability efforts.

Future Plans

Looking ahead, LTM is focused on securing funding to implement recommendations from its decarbonisation reports. The museum aims to advance building electrification, finalise its gas boiler replacement strategy, and further integrate renewable energy solutions. By 2030, LTM plans to introduce heat pumps, PV panels, and low-flow water appliances across both estates, marking a significant milestone in its net zero journey.

Conclusion

The London Transport Museum’s recent efforts to reduce energy and carbon emissions exemplify how cultural institutions can lead in sustainability while navigating the complexities of historic infrastructure. Through JB’s Capital Investment Readiness Programme, LTM has transformed challenges into opportunities, establishing a robust framework for decarbonisation. With a clear strategy and growing confidence in securing funding, LTM is well-positioned to achieve net zero emissions, setting a precedent for other heritage organisations striving for environmental responsibility.
