Natural
Objective:
Environmental net gain
Overview
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 it matters
We invest not only in quantity but in quality of the green and blue infrastructure we provide. We seek to incorporate nature at the core of all our development sites, preserving existing features of value and capturing every opportunity to enhance the environment, enabling people and nature to flourish collectively. The re-use and re-purposing of the land we develop seeks at all times to provide environmental net gain for the communities we create.
This includes early tree planting to maximise sequestration potential and improve health and wellbeing attributes within our sites, creating usable and sustainable green landscape, effective surface water management and the responsible use of natural resources.
Action areas
- Enhanced landscaping
- Enhanced biodiversity
- Resource efficiency
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.
Target
2025 target:
- Plant an average of 25 trees for each house occupied by 2025.
Performance
Over the course of 2022/23, the average number of trees planted per household across all strategic land sites stayed the same as 2021/22, at 32, and continued to exceed our 2025 target. Newark significantly increased its tree planting ratio from one to nine trees per household and to a lesser extent Priors Hall increased its ratio also. Alconbury, Rugby and Wintringham all reduced slightly. Waterbeach wasn’t included last year as no homes had been built, but this year there are 609 trees per household currently built on site reflecting the significantly early tree planting already undertaken.. This will level off with time as further houses are built. Going forward we will endeavour to maintain this average score and target it for each site as housebuilding across our sites continues thereby reducing the initial benefit of early placemaking and landscaping.

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.
Targets
2025 target:
- Achieve 25% biodiversity net gain as a minimum overall on all our sites.
Performance
In 2021/22 the U&C assessment methodology for biodiversity net gain (BNG) was changed to the latest Defra metric as opposed to the Warwickshire County Council (WCC) metric. Over the course of 2022/23, the BNG assessments for Priors Hall and Newark were updated and compared with the previous year. The subsequent average score for all sites in delivery was 26%, currently exceeding the 2025 target. The only sites falling below the 25% target are Hinxton and Priors Hall.Over time, we expect that as further key phases come forward across the sites, the BNG scores will trend upwards.

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.
Target
2025 target:
- Divert from landfill a minimum 95% construction and demolition waste.
Performance
Contractors appointed by U&C maintained their good performance over recent years to divert construction and demolition waste from landfill. In 2022/23 the diversion rate was 99%. All strategic sites in delivery, with the exception of Alconbury, Hinxton and Priors Hall, bettered the 95% target.
