Bristol is at the forefront of the UK’s transition to net zero.
We have a strong track record in community energy, low‑carbon innovation and industrial decarbonisation, alongside major programmes that are future‑proofing our infrastructure and strengthening energy security.
As a Council we are scaling this work through the delivery of new heat networks, investment in clean and local energy generation, and the development of net zero districts bringing together homes, jobs and transport.
Through our long‑term clean‑energy partnership, Bristol City Leap, Bristol is coordinating investment and delivery across heat, power and local energy systems at city scale. We are also supporting green skills, retrofit and innovation, while working with partners to build the workforce and creating the supply chains needed to deliver what we need, when we need it.
Decarbonisation and net zero
A step-by-step green action plan is being developed to decarbonise industries in and around Bristol Port, covering the areas of Portbury, Avonmouth and Severnside. The plan looks for opportunities to make firms more energy efficient, using cleaner, greener fuels. The actions encourage the use of heat networks and other green technologies and in the industries where it isn’t possible to completely stop generating carbon, carbon capture technologies will be considered.
The area is already home to many leading energy and materials companies, such as GENeco, Accolade Wines, Etex Performance Systems and Suez Energy Recovery Centre.
Hallen Marsh presents a strategic and timely opportunity to develop a clean‑energy and industrial decarbonisation hub serving the Avonmouth and Severnside industrial area, one of the South West’s most significant employment and logistics locations.
The 18-hectare site forms part of a suite of new industrial land allocations at Avonmouth proposed in the new local plan.
The opportunity is to bring forward large-scale clean energy generation, storage and grid connected infrastructure, alongside facilities that support industrial decarbonisation and energy resilience. The site offers scale, strategic location and the ability to aggregate demand across multiple users, creating a strong platform for long-term investment.
Hallen Marsh also benefits from a high‑quality environmental and flood‑defence context delivered through the Avonmouth and Severnside Enterprise Area Ecology Mitigation and Flood Defence Programme, in partnership with South Gloucestershire Council and the Environment Agency. Significant upfront investment has already provided flood protection, ecological mitigation and long‑term resilience, creating a robust and de‑risked setting for infrastructure development.
