Cambridge City Council has approved four new plans to help build climate resilience, increase tree canopy cover to 20% by 2050, support biodiversity in Cambridge, and get its own operations to net zero by 2030 – as councillors restate and strengthen their commitment to tackling the climate and environment crises and improving people’s quality of life in Cambridge.
A recent Cabinet meeting approved:
The Climate Change Strategy 2026-2031 – setting out how the council will continue to target net zero emissions in its own operations by 2030, and support the city to do the same.
A plan to invest £600,000 in the council’s City Centre Heat Network project – a network of air source and river source heat pumps to provide lower-carbon energy to city centre heritage buildings, with potential 93% reduction in emissions over 40 years for the connected buildings, plus significant associated improvements to air quality.
The council’s updated Biodiversity Strategy 2026-2031, with a vision for bigger, better, more joined up nature in every ward of the city; with quality open space within walking distance of people’s homes or workplaces.
The council’s Urban Forest Strategy 2026-2036 – reaffirming the council’s promise to restore, protect and grow Cambridge’s tree canopy cover to 20% by 2050, within the context of a changing climate and the rising threat of pests and diseases.
Climate Change Strategy 2026-2031
The new Climate Change Strategy comes after a decade of steady carbon reduction actions with the council’s own emissions down by 51.9% since 2014/15 – including an 8.1% reduction in the last year alone.
This is a result of reducing emissions from its own buildings and fleet vehicles, and embedding climate action across all council services.
The council will continue to focus on existing areas of work that help minimise the wider city’s emissions, which have also reduced by 47.3% since 2005, such as:
retrofitting council homes and other buildings;
minimising waste;
and supporting sustainable food, renewable energy and sustainable travel.
The 2026 strategy sets a near-term goal to bring the council’s emissions down 69% by 2028, and introduces new areas of focus:
Integrating climate-adaptation into the whole strategy – for example, enhancing nature, preserving water and ensuring new buildings will be able to cope with heat, or drought, by designing them to use less water, stay cool, and be resilient during extreme weather.
Incorporating emissions reductions into the council’s supply chain and procurement processes – for example, requiring contractors to use electric vehicles, or that lower carbon materials are used in construction.
Expanding support and advice for residents and businesses to adopt low-carbon lifestyles – recognising that around one third of required UK emissions reductions rely on household decisions.
Collaboration – deepening relationships with and between key partners in the community and with business, innovation and anchor institutions in the city as part of a city-wide approach to climate change and inclusive innovation.
City Centre Heat Network
The council plans to work with key city institutions to develop a network of air source and river source heat pumps to provide lower-carbon energy to reduce carbon emissions by 93% over 40 years for many of the city’s historic or listed buildings, which are especially challenging to reduce carbon emissions on, and the council’s own Guildhall, Corn Exchange and Parkside pools.
Biodiversity Strategy 2026-2031
The mid-term review of the Biodiversity Strategy 2022-2030 shows that good progress has been made – especially through local community partnerships and projects – but nature is still under pressure and needs more coordinated action.
The updated strategy will continue to focus on protecting and improving habitats; creating a joined-up nature network to link habitats across the city; engaging communities; and delivering biodiversity net gain by ensuring new developments contribute to measurable improvements for nature – keeping the ambitious 20% biodiversity net gain commitment for council-led developments. New commitments include:
Increasing biodiversity in every ward of the city, with annual reporting and longer-term habitat and species monitoring.
Focusing on large-scale, joined-up projects, with stronger collaboration with residents, businesses, universities and regional partnerships.
A new ambition for Cambridge to become an accredited Nature City.
For all Cambridge residents to have nature rich green space within walking distance of their home or workplaces.
Designation of two new Local Nature Reserves at Fulbourn Road Open Space and at Church End in Cherry Hinton.
Urban Forest Strategy 2026-2036
The council manages a large and evolving tree stock undertaking regular inspections and maintenance.
The council has also delivered extensive tree planting programmes across its land and led on a range of engagement initiatives including the popular Trees for Babies scheme – with a focus on species diversity and sustainability.
Between 2008 and 2018, tree canopy was recorded as having increased from 17.1% to 17.6% reflecting the combined increase across public and private land and reinforcing the need for collective action.
This work will continue, with:
The council’s ambition for Cambridge’s tree canopy to increase to at least 20% by 2050.
Expanding the council’s focus from caring for council-owned trees, to trees on privately owned land, and the need to work with landowners, developers, institutions and communities.
A greater emphasis on protecting existing trees and enabling them to grow to maturity – recognising that large established trees deliver faster and bigger climate and biodiversity benefits than planting alone.
Continued expansion of the council’s use of tree canopy data to guide planting, protection and investment and support residents, landowners, managers and planners to make more informed decisions.
The three strategies and the report on the City Centre Heat Network can all be found in the Cabinet meeting agenda.
