Biodiversity Net Gain

Biodiversity Net Gain (BNG) has gained traction as a promising approach to reconcile development with biodiversity conservation. Several case studies from around the world showcase the successful implementation of Biodiversity Net Gain in various projects. These real-life examples demonstrate the positive impact of BNG on both ecosystems and human communities. Let’s explore some compelling case studies in Biodiversity Net Gain.

1. Crossrail Project – London, UK

The Crossrail project, a major railway infrastructure development in London, UK, is an exemplar of Biodiversity Net Gain in an urban setting. To achieve BNG, the project implemented a comprehensive strategy that included creating wildlife-friendly habitats and green spaces along the railway route. This involved planting native vegetation, constructing green corridors, and incorporating green roofs and walls in stations. The result was not only a net gain in biodiversity but also enhanced aesthetics and improved air quality for city residents.

2. CEMEX Quarry Restoration – Lancashire, UK

CEMEX, a global building materials company, undertook a remarkable Biodiversity Net Gain project at their quarry site in Lancashire, UK. After the quarry’s operation ceased, CEMEX transformed the site into a biodiversity-rich nature reserve at Wetlands, grasslands, and woodlands were restored, providing vital habitats for numerous plant and animal species. The project showcased the potential of industrial sites to be transformed into thriving ecological havens, promoting a harmonious coexistence between nature and human activities.

3. HeidelbergCement – Belgium

HeidelbergCement, a multinational building materials company, embraced Biodiversity Net Gain as part of its commitment to sustainability. In Belgium, they successfully implemented a biodiversity enhancement program across several Driveway Landscaping Augusta GA. By restoring habitats, planting native vegetation, and providing nesting sites for birds, the quarries became ecologically valuable landscapes. HeidelbergCement’s approach not only benefited biodiversity but also contributed to the well-being of nearby communities and garnered positive recognition from stakeholders.

4. Throsby Park – New South Wales, Australia

The Throsby Park development in New South Wales, Australia, exemplifies how Biodiversity Net Gain can be integrated into urban planning. The project included the creation of a biodiversity corridor to connect fragmented habitats and enhance biodiversity in the region. By prioritizing green spaces and wildlife-friendly landscaping, Throsby Park became a model for sustainable urban development that fosters a closer relationship between people and nature.

5. Eden Project – Cornwall, UK

The Eden Project, renowned for its iconic geodesic biomes, embraced Biodiversity Net Gain as a core principle in its expansion plans. The project aimed to create a positive impact on local biodiversity while developing new attractions. The Eden Project collaborated with local conservation groups to ensure that the expansion enhanced the ecological value of the site and supported native flora and fauna. The successful implementation of Biodiversity Net Gain further cemented the Eden Project’s reputation as a leader in sustainability and ecological conservation.

6. Oyu Tolgoi Mine – Mongolia

In the mining industry, Oyu Tolgoi, a copper-gold mine in Mongolia, stands out for its exemplary Biodiversity Net Gain efforts. The mine’s operator, Rio Tinto, undertook an extensive biodiversity offsetting program, where they restored and protected larger areas of habitat compared to the land used for mining. By implementing robust monitoring and adaptive management practices, they ensured the successful conservation and restoration of biodiversity in the region.

7. Bristol Airport Expansion – UK

The expansion of Bristol Airport in the UK incorporated Biodiversity Net Gain as a core principle. The project involved creating new habitats, planting native species, and enhancing existing green spaces around the airport. The BNG measures not only mitigated the environmental impact of the expansion but also enhanced the airport’s reputation as an environmentally responsible entity.


These case studies demonstrate that Biodiversity Net Gain is not just a theoretical concept but a practical and effective approach to achieving sustainable development. From urban infrastructure to industrial sites and natural reserves, BNG has shown its ability to create a positive impact on biodiversity while supporting human communities. As more projects integrate Biodiversity Net Gain into their plans, we move closer to a future where development and biodiversity conservation go hand in hand.
