Cambridgeshire Green Vision

The Cambridgeshire Green Vision establishes a cohesive planning framework that reconciles the county’s pressing housing demand with an uncompromising commitment to climate resilience and ecological integrity. Rather than treating environmental goals as constraints, this vision treats them as the primary drivers of spatial organization and land-use decisions. The overarching objective is a net-zero county by 2050 that is measurably nature-positive—a dual mandate that requires a systemic shift in how development is conceived, consented, and managed.

This vision rests on four integrated policy pillars that span the county's diverse landscape, from the intensive Fenland agriculture to the expanding urban cores of Cambridge, Ely, and Peterborough.

Biodiversity and Nature Recovery

Nature is the foundation of the vision. The policy moves beyond a simple "no net loss" approach toward a mandated biodiversity net gain (BNG) on every new development, with a preference for a 20% uplift. This is supported by three key strategies:

  • Ecological Connectivity: Development must preserve and enhance the county's blue-green infrastructure. New sites are required to contribute to regional green corridors that allow species movement and carbon sequestration.
  • Nature-Based Solutions: Flood risk management is steered toward wetlands and woodlands rather than hard engineering, using natural storage to mitigate the increasing frequency of extreme weather events.
  • Agricultural Transition: The policy encourages a shift toward agroecology and rewilding on marginal lands, integrating production with habitat restoration.

Energy and Decarbonisation

Decarbonising the built environment is a central planning lever. The vision mandates a "fabric-first" approach to new construction, requiring high thermal performance and a transition away from gas heating. Key regional initiatives include:

  • District and Neighborhood Heat Networks: Planning preference is given to developments that can connect to shared heat networks, including waste heat recovery from industrial and data centre clusters.
  • Renewable Integration: Solar PV is the default for large-scale developments, and the county seeks to maximize community-scale geothermal and wind opportunities on brownfield and degraded land.
  • Circularity in Materials: The policy promotes the reuse of aggregates and the embodied carbon accounting of building materials to minimize the carbon debt of new construction.

Sustainable Transport and Active Travel

Reducing car dependency is essential for meeting climate targets. The vision prioritizes transport modes that favor people over private vehicles. Key measures include:

  • Active Travel First: Every new housing scheme must provide safe, segregated cycling and walking routes that connect to the regional active travel network.
  • Transit-Oriented Development: Higher densities are concentrated near existing and planned rail and bus hubs to maximize the utility of public transit.
  • Logistics and Freight: Strategic freight corridors are protected, while local deliveries are encouraged through consolidation centres and electric last-mile solutions.

Sustainable Housing and Urban Form

The housing challenge is met through intelligent spatial organization that protects the rural character while maximizing site efficiency. The vision promotes a tiered approach to land use:

  • Brownfield and Infill First: The primary housing supply must come from derelict and underused land within existing towns and cities.
  • Smart Density: In urban cores, the policy supports height and density where it supports the public realm and avoids the urban sprawl that characterizes the county's rural fringes.
  • Sensitive Rural Growth: New rural villages are rare and must be demonstrably self-sustaining and located on land that would otherwise be lost to intensive agriculture.

By weaving these four pillars into a single coherent policy, the Cambridgeshire Green Vision ensures that every planning decision contributes to a county that is more resilient, more biodiverse, and more prosperous for future generations.
