BNG and Climate Change
Biodiversity Net Gain (BNG) and climate change are now inseparable themes in sustainable development. Both crises biodiversity loss and global warming demand integrated solutions.
In the UK, BNG is mandated by the Environment Act 2021, ensuring that new developments deliver at least a 10 per cent increase in measurable biodiversity value, sustained for 30 years. Delivering BNG contributes directly to climate adaptation and mitigation by restoring habitats that capture carbon, regulate temperature, and reduce flood risk. Integrating BNG and climate change strategies therefore offers not just compliance, but a route to more resilient places and healthier ecosystems across England.

BNG and Climate Change PDF: Understanding the Policy Link
Many professionals seek a clear BNG and climate change PDF summary to grasp how the two policies interconnect. In simple terms, BNG requires developers to enhance biodiversity through habitat creation or restoration, while climate policy seeks to cut greenhouse-gas emissions and build resilience. A single well-planned BNG project can achieve both goals: tree planting sequesters carbon; wetlands store floodwater; and flower-rich grasslands increase pollinator diversity while capturing CO₂ in soil. Government guidance notes that “by increasing biodiversity, we can contribute to a sustainable future more resilient to climate change.” Hence, embedding climate metrics within BNG assessments ensures projects meet dual sustainability objectives ecological recovery and carbon reduction.
Biodiversity and Climate: The Twin Challenge
The loss of biodiversity and the escalation of climate change reinforce each other. Damaged ecosystems absorb less carbon, while climate-driven droughts, heatwaves, and floods further degrade habitats. Restoring natural capital through BNG reverses this cycle. Diverse habitats from woodlands to wetlands act as natural carbon sinks and buffers against extreme weather. In urban contexts, BNG greening measures such as trees, green roofs, and rain gardens cool microclimates and manage stormwater. Addressing biodiversity and climate together transforms planning from reactive mitigation to proactive resilience building. This approach aligns with the UK’s Nature Recovery Network strategy, demonstrating that thriving nature is the foundation of long-term climate stability.
BNG and Climate Change 2021 Regulations
The Environment Act 2021 made BNG and climate change integration a statutory consideration in English planning. Since February 2024, most developments must deliver a 10 per cent biodiversity net gain, measured using the Defra Biodiversity Metric 4.0. The legislation links biodiversity outcomes to wider environmental targets such as Net Zero 2050. Local Planning Authorities (LPAs) now expect developers to demonstrate how their BNG proposals contribute to climate resilience through habitat types that sequester carbon or mitigate flooding. Projects must provide a 30-year Habitat Management and Monitoring Plan to ensure benefits persist despite future climate stressors. Understanding these 2021 regulations is essential for anyone preparing environmental statements, impact assessments, or design frameworks that must satisfy both biodiversity and climate objectives.
BNG Habitat Types and Carbon Storage
Different habitat types created under BNG contribute varying levels of carbon storage and resilience.
- Woodland creation – High carbon sequestration; long-term climate mitigation.
- Hedgerows and scrub – Moderate carbon capture; vital for connectivity and shelter.
- Grassland and meadow restoration – Builds soil carbon and supports pollinators.
- Wetlands and reedbeds – Trap sediment and lock carbon in anaerobic soils.
- Saltmarsh and coastal habitats – Exceptional “blue-carbon” sinks, buffering sea-level rise.
Selecting habitat types with both biodiversity and climate benefits maximises the value of BNG and climate change investment. During design, ecologists evaluate habitat distinctiveness, condition, and strategic significance using the biodiversity unit metric. This ensures that the most climate-beneficial habitats are prioritised within development layouts and off-site compensation schemes.
BNG Carbon Co-Benefits Explained
BNG carbon co-benefits arise when actions taken for biodiversity also enhance carbon sequestration or reduce emissions. Planting native woodland, restoring peatland, or reconnecting rivers all deliver measurable biodiversity units while storing atmospheric carbon. These co-benefits strengthen compliance with climate policies and can contribute to corporate sustainable development goals. For example, a business delivering BNG through rewilding initiatives might simultaneously report its carbon removals under Scope 3 emissions. Integrating carbon-accounting frameworks into BNG reports allows developers to evidence both ecological and climate performance. This transparent dual reporting builds investor confidence and supports national ambitions for a low-carbon, nature-positive economy.
Nature-Based Solutions UK for Climate Resilience
Across the UK, nature-based solutions (UK) are being used to link BNG and climate change strategies. Examples include:
- Urban SuDS (swales and ponds): manage floods, purify runoff, and create wetland habitats.
- Green corridors and wildlife corridors: connect fragmented landscapes and allow species migration under changing climates.
- Green roofs and walls: reduce heat islands and provide nesting space for birds and pollinators.
- Restored rivers and floodplains: store floodwater and improve aquatic biodiversity.
These measures deliver multiple ecosystem services cooling, shading, flood mitigation, and health benefits demonstrating how nature-based solutions UK translate BNG policy into tangible climate resilience on the ground. They exemplify environmental net gain: projects that add more value to nature and people than they remove.
Biodiversity Net Gain and Environmental Net Gain
The UK Government’s ambition extends beyond biodiversity toward environmental net gain, integrating air, water, soil, and carbon benefits. Biodiversity Net Gain and Environmental Net Gain operate as complementary frameworks: the former quantifies ecological uplift, the latter measures broader ecosystem service improvements. Delivering both requires interdisciplinary collaboration among ecologists, climate scientists, and planners. When a development delivers BNG using climate-resilient habitat designs, it contributes automatically to wider sustainability metrics reducing the ecological footprint and enhancing natural capital. This integrated approach supports the United Nations’ Sustainable Development Goals and underpins the UK’s pathway to climate neutrality.

BNG and Climate Change Map: UK Examples
Across England, local authorities are publishing BNG and climate change maps to identify where habitat creation best supports carbon reduction. For instance, Greater Manchester’s Local Nature Recovery Strategy highlights peatlands and woodlands as priority zones for both biodiversity and carbon gain. Similar mapping in Devon and Oxfordshire links BNG opportunity areas with flood-risk reduction corridors. These GIS-based tools guide developers toward sites offering the strongest BNG carbon co-benefits, ensuring each investment produces maximum ecological and climate value.
