Halnaker Hill Natural Capital Launches Voluntary Biodiversity Credits on Earthly Marketplace
Halnaker Hill Natural Capital (HHNC) has partnered with Earthly to offer Voluntary Biodiversity Credits from its Halnaker Hill Farm project through Earthly’s marketplace. This initiative follows the project’s successful completion of Earthly’s rigorous Keystone 3.0 assessment, which evaluates 168 indicators across carbon, biodiversity, and social impact. Notably, fewer than 9% of projects meet the standards required to pass this evaluation.
Located near Chichester, Sussex, Halnaker Hill Farm represents one of the UK’s largest Biodiversity Net Gain (BNG) schemes. The farm, acquired by HHNC in 2024, is undergoing a transformation from decades of wheat farming into a restored natural landscape spanning 330 acres. The restoration includes reintroducing habitats such as hedgerows, grasslands, ponds, woodlands, and wildflower meadows, alongside grazing cattle, sheep, and pigs to support natural land management.
HHNC’s Sales & Marketing Director, Greg Lukasiewicz, emphasised the significance of the partnership: “We are proud to have received Earthly’s stamp of approval and our new partnership underlines the impact we have made at Halnaker Hill Farm since we acquired the site in 2024, and its ability to provide organisations and individuals with a responsible way to invest in biodiversity and the fight against climate change, while setting a new benchmark for sustainable, regenerative farming.” He added, “We are looking forward to working with Earthly to make high-integrity BNG and biodiversity credits accessible to those seeking a credible investment in nature with long-term environmental impact.”
The project delivers over 850 biodiversity units, registered with the South Downs National Park Authority and Natural England, making it one of the largest single BNG land banks in England. A legally binding 30-year stewardship is secured through a Section 106 agreement between HHNC and the South Downs National Park Authority.
Earthly’s Voluntary Biodiversity Credits are based on DEFRA-assessed parcels of land, divided into 9×9 metre squares. This approach ensures rigorous monitoring, verification, and management while maintaining an entry price below £100 per credit. The model allows businesses and individuals to build customised nature portfolios at various investment levels.
Oliver Bolton, CEO and co-founder of Earthly, highlighted the project’s value: “We are genuinely excited to bring this project to Earthly’s marketplace. Halnaker Hill is the kind of project that reminds you why nature restoration matters, and why doing it well is both harder and more valuable than it looks.” He continued, “Businesses supporting voluntary biodiversity credits are addressing climate and nature risk – increasingly in demand by boards and investors – and enabling ecosystem services from the restored landscape to improve flood risk, air quality, biodiversity and local economies.” Bolton also praised the methodical approach of the teams involved: “The team at Halnaker Hill Natural Capital and Kingsbridge are paying down ecological debt methodically, hectare by hectare, guided by science and backed by legal certainty.”
Halnaker Hill Farm is owned by HHNC, with commercial operations managed by Kingsbridge, a prominent developer of commercial projects in southern England. Interested parties can purchase Voluntary Biodiversity Credits for Halnaker Hill Farm directly through Earthly’s website.
