Celebrated for its outstanding contributions to sustainable urban development and innovative public-private partnerships, Ameresco’s Bristol City Leap project has set a new standard in addressing climate change and enhancing community resilience.

Bristol City Leap project has been awarded the prestigious 2024 Award of Distinction for Public-Private Collaboration in Cities by the Global Partnership for Local Investment, an initiative of the World Economic Forum in collaboration with UN-Habitat. This accolade recognises the groundbreaking efforts of Bristol City Leap in addressing the urgent need to reduce carbon emissions and meet ambitious climate targets through an innovative public-private partnership.

Bristol City Leap is a pioneering, twenty-year joint venture between Bristol City Council, Ameresco, and Vattenfall Heat UK. The initiative focuses on achieving city-scale decarbonisation by installing low carbon energy infrastructure, primarily funded and delivered by the private sector. The goal is for the joint venture to attract £1 billion in investments over the partnership’s duration, with at least £424 million committed by 2027. The commitment to Bristol City Leap has continued across political administrations with cross-party support.

“Bristol City Leap exemplifies how cities can leverage innovative public-private partnerships to drive sustainable urban transformation,” said Jeff Merritt, Head of Urban Transformation at the World Economic Forum. “This award recognises Bristol’s leadership in demonstrating that collaboration at scale is key to addressing global climate challenges while delivering tangible benefits to local communities.”

Key outcomes:

  • EV Charging Network: £18 million investment in the city’s EV charging network over the first five years.
  • Council Operational Buildings: £2.5 million projects in council operational buildings for Building Management Systems, energy-efficient chillers, and LED lighting, with a further £10 million of projects in advanced development to commence within the next 12 months.
  • Schools: Installation of solar photovoltaic (PV) systems and air-source heat pumps in schools to reduce their carbon footprint.
  • Social Housing Stock: £57 million investment in the city’s social housing stock by 2029, including £16 million for refurbishing nine blocks of flats and a £7.8 million window replacement program to improve energy efficiency.
  • Heat Network Expansion: Expansion of the city’s heat network by Vattenfall, expected to supply low carbon heat to the equivalent of 12,000 homes over the next five years.
  • Large-Scale Renewable Development: An £83 million program of large-scale renewable development, much of which will take place on council-owned land.

Collectively, these initiatives are projected to result in an impressive reduction of approximately 140,000 tonnes of carbon emissions and the installation of 182 MW of clean, renewable energy over the five years.

This substantial impact not only contributes to Bristol’s ambitious climate goals but also sets a benchmark for other cities aiming to achieve similar environmental milestones. By harnessing the power of innovative technologies and sustainable practices, Bristol City Leap is paving the way for a greener, more resilient future.

“This award is a testament to the power of collaboration in driving meaningful change,” said Mark Apsey MBE, Senior Vice President at Ameresco. “By creating a long-term place-based partnership between Bristol City Council and Ameresco we are attracting investment in energy projects to take action toward decarbonisation. This approach is unlocking significant social value by creating good local jobs, improving local infrastructure and providing support for local communities. We are keen to see this world first model replicated rapidly in other cities and places to accelerate mitigation action on climate change.”

“The Bristol City Leap partnership is a pioneering collaboration that demonstrates the value of combining the best of the public and private sectors to deliver real change for our city,” said Councillor Tony Dyer, Leader of Bristol City Council. “Through working together, we are bringing to Bristol a number of the interventions required to move towards a more sustainable, energy resilient city. This approach is also creating new jobs in an emerging green energy sector and has the power to unlock tremendous amounts of social benefits for communities across the city. This award demonstrates that we’re on the right track and we look forward to continuing to work as a partnership to achieve our ambitious goals.”

The project emphasises social value, with local economic benefits estimated at £61.5 million in social value, £55 million in contracts with the local supply chain, and over 1,000 local jobs, work placements, and apprenticeships. A £1.5 million Community Energy Fund has been established, with the first awards to community groups being made, and the delivery of £4 million energy efficiency measures for the city’s most vulnerable households is helping to tackle fuel poverty.

Looking ahead, Ameresco is developing relationships with many interested UK and international cities to share the lessons from Bristol and set up new outcome based public-private partnerships.
