Environmental net gain

Natural Capital logo


The Natural capital relates to the protection and enhancement of the environment, both within the local context and through contributing to wider climate and biodiversity challenges.

Why do we pursue environmental net gain?

The UK’s new Environment Bill has formalised an expectation of developers to combat these trends, by introducing a requirement for a minimum 10% biodiversity net gain on all new housing schemes.
These policy developments align with our strategic vision to leave the natural and physical environment in a measurably better state than before. We want to create beautiful, sustainable and community focused places with nature at the core of all our development sites. 

What is the journey?

To achieve this objective, we have identified three action areas to provide a strategic focus for our efforts and commitments: first, to leverage our landscape-led design to deliver environmental net gain with a focus on planting new trees; second, to achieve enhanced biodiversity through  avoiding and minimising negative impacts on biodiversity before compensating through the creation of ecologically rich habitats on-site; and third, to maximise resource efficiency and the resilience of environmental ecosystems. The importance of biodiversity net gain is highlighted through its inclusion as one of our three universal challenges.

Developed landscaping

Our focus in this area is the targeted provision of an incredible element of green infrastructure: new trees. Trees are one of the most powerful weapons in the fight against climate change, removing carbon dioxide from the air, storing carbon and releasing oxygen into the atmosphere. In addition, they can help to prevent flooding, reduce temperature and pollution, and keep soil rich in nutrients. Providing more of them is also directly linked to addressing two of the three universal challenges we have identified as being relevant to sustainability in the built environment: biodiversity and health and wellbeing.


2025 target: 

  • Plant an average of 25 trees for each house occupied by 2025.


In 2020/21, an average of 31 trees were planted per household across all strategic land sites, exceeding our 2025 target.

Enhanced biodiversity

Our commitment to increasing ecological value on our developments is not new. However, we have redefined our approach to maximise our biodiversity net gain for stronger and more resilient local ecosystems.


2025 target: 

  • Achieve a 12% biodiversity net gain as a minimum overall on all our sites.


Average BNG in 2020/21 was 8.7%, significantly up on the year before. If biodiversity continues to increase across all sites at the current rate, the 2025 target as an average across all
sites will be achieved.

Resource efficiency

Resource efficiency is of paramount importance to us. We seek to maximise the incorporation of key circular economy principles in our schemes to ensure efficient use of natural resources and the minimisation of waste sent to landfill. We will also collaborate with our housebuilder partners to define suitable targets for water consumption in dwellings and recycling rates.


2025 target: 

  • Divert from landfill a minimum of 92% construction and demolition waste.


In 2020/21, 94.5% of construction and demolition waste by weight from community buildings and infrastructure delivered by Urban&Civic was diverted from landfill, exceeding the 2025 target.
