Climate & energy

The human version (we wrote this, not the council)This section describes the evidence base behind the Plan. A wide range of technical studies covers housing and employment needs, transport, infrastructure, climate change, sustainability, health and design. Key studies include the Housing and Economic Land Availability Assessment (HELAA) and the New and Expanded Settlement Study (NESS), which test whether promoted sites are suitable, available and achievable. Other evidence covers flood risk, water, renewable energy, retail and gypsy and traveller accommodation. A full list is on the Council's website.

The human version (we wrote this, not the council)This section explains the national and strategic context for the Plan. It has been prepared under the December 2024 National Planning Policy Framework (NPPF), which requires plans to cover at least 15 years and to balance economic, social and environmental aims. Using the Government's standard method, Buckinghamshire's housing need is 4,344 homes a year, or about 91,230 homes over the plan period to 2045. The Council has worked with neighbouring authorities on cross-boundary issues and aligned the Plan with the Local Transport Plan.

The human version (we wrote this, not the council)This section describes transport and infrastructure. Buckinghamshire has strong road and rail links, and major projects such as HS2 and East West Rail, including a new station at Winslow, will shape future connectivity. However, parts of the network are at or near capacity, east-west links are limited and rural public transport is patchy. Transport accounts for about 51% of the county's carbon emissions. Healthcare, education, utilities and digital infrastructure also face pressures, so development needs to be matched by timely infrastructure delivery.

The human version (we wrote this, not the council)This section sets out the Plan's vision for Buckinghamshire in 2045. It describes a county that has kept its rural character, protected the Chilterns National Landscape and made the most of brownfield land (previously developed land). New communities are healthy, well designed and served by the right infrastructure, with housing for different groups including key workers. The economy has grown in creative industries, space and high-performance technology, town centres have been revitalised, and green spaces, biodiversity and sustainable travel have been strengthened.

The human version (we wrote this, not the council)This section sets out Objective 2, on climate change. It supports the move to a net zero carbon Buckinghamshire by 2050, directing growth to the most sustainable locations and designing development to cope with flooding and climate extremes. Transport causes 51% of the county's emissions. Areas at higher flood risk include parts of South Bucks, the Thames near Wycombe, east of Aylesbury and around Buckingham. Development is steered first to sites with the lowest flood risk.

The human version (we wrote this, not the council)This section sets out Objective 8, on transport and digital connectivity. It aims to improve connections across and beyond the county through new sustainable transport infrastructure, safe walking and cycling routes, better public transport and improved digital coverage. Modelling shows planned growth will significantly increase traffic, especially around Aylesbury and High Wycombe. East West Rail will improve links in the north, while HS2 passes through without stopping. Many rural residents rely on cars, so the location of development is critical.

The human version (we wrote this, not the council)This section explains the purpose of the renewable energy policy: supporting the move to a low-carbon, climate-resilient future through energy efficiency, renewable energy generation and careful use of natural resources. It describes how delivery will be supported by the detailed Chapter 7 policies on matters such as water, flooding, biodiversity, landscape, Green Belt, design and heritage, so that renewable energy schemes are well located and protect Buckinghamshire's environment.

The human version (we wrote this, not the council)This policy supports low-carbon development and asks applicants to follow an energy hierarchy: cut energy demand first, supply energy efficiently, then use renewable sources. Schemes of 100 or more homes (50 or more in off-gas areas) and non-residential buildings of 1,000 sqm or more should assess district heating. Opportunity areas for wind, solar and battery storage are mapped, with tests on landscape, wildlife, heritage, amenity and road safety. It notes the Future Homes Standard from March 2027, cutting new homes' carbon emissions by around 75 to 80%.

The human version (we wrote this, not the council)This section explains the purpose of the natural environment policy: conserving and enhancing Buckinghamshire's biodiversity, landscapes, water and green spaces while strengthening resilience to climate change. It sets out how delivery will run through the detailed Chapter 7 policies on matters such as water quality, biodiversity gain, green infrastructure, trees, protected sites, Green Belt, landscape character, flood risk and drainage.

The human version (we wrote this, not the council)This policy sets out how the Council will protect and improve the natural environment and respond to climate change. It commits to conserving the Chilterns National Landscape, delivering at least 10% biodiversity net gain on qualifying developments, and supporting nature recovery through the local strategy. It also covers protecting water quality, aiming for good status in rivers and groundwater by 2027, directing growth to places that reduce car travel, using sustainable drainage, adopting higher water efficiency standards, and supporting renewable energy.

The human version (we wrote this, not the council)This policy requires development to conserve and enhance watercourses and their corridors, including their biodiversity, landscape, flood management and recreation value. Culverting or hard engineering of watercourses is not supported, and opportunities to restore rivers to a more natural state should be actively pursued. Development next to a watercourse must keep a natural buffer of at least 10 metres from the top of the bank, with no lighting, rising to at least 15 metres for chalk streams such as the River Chess and River Misbourne. Chalk streams are a globally rare habitat with stronger protection.

The human version (we wrote this, not the council)This policy supports moving freight from road to rail, along with facilities for sustainable deliveries and first mile and last mile solutions. It also supports smart warehousing, meaning the retrofitting of older warehouse stock with digital and automated systems. New freight proposals must not significantly harm the local area, and retail and employment sites must provide suitable access, loading and unloading facilities. Freight and logistics is a major part of the local economy, representing 72.1% of modern economy roles in Buckinghamshire in 2023.

The human version (we wrote this, not the council)This policy directs development to areas at the lowest risk of flooding from all sources, taking account of climate change. Inappropriate development in high or medium flood risk areas will not be supported, and the functional floodplain is safeguarded for storing flood water. Site-specific Flood Risk Assessments are required for development in at-risk areas and all sites over 1 hectare, and sites of 50 or more dwellings need a strategic drainage strategy. Building over existing culverts is not allowed, and all developments in Chesham and High Wycombe need a surface water drainage strategy.

The human version (we wrote this, not the council)This policy requires all new development, except most householder schemes, to include Sustainable Drainage Systems (SuDS), which mimic natural drainage by slowing and storing rainwater on site. Run-off must not materially increase, with greenfield sites limited to existing greenfield rates. Schemes must show no flooding in a 1 in 30 year storm and safe containment of a 1 in 100 year storm plus climate change. A drainage hierarchy applies, preferring rainwater reuse and infiltration over sewer connections, and long-term maintenance plans must be secured.
