Question to the Department for Environment, Food and Rural Affairs:

To ask His Majesty's Government what assessment they have made of the potential private investment into nature through the Nature Investment Standards Programme.

Defra sponsors the British Standards Institution’s (BSI) Nature Investment Standards Programme to work with industry to develop a suite of standards to ensure that as they develop, UK nature markets secure positive outcomes for the environment. These standards have been developed using a market-led process with input from market experts, including private companies, and feedback from public consultations.

The standards are designed to drive consistency and integrity across UK nature markets, and Government is putting in place a range of other interventions to stimulate more private investment into nature recovery. At this stage, it has not been possible to attribute specific levels of investment to the standards, so no such assessment has been made. In line with the Magenta book, Defra is evaluating the impact of the standards, including on levels of investment.

On 24 March 2026, following consultations on earlier draft versions, BSI published standards for the Supply of Biodiversity Benefits and the Supply of Nutrient Benefits. These are available, along with all other published standards and those in development, at: www.gov.uk/government/publications/nature-investment-standards/the-bsi-nature-investment-standards (see attached). A draft standard for the Supply of Nature-based Carbon Benefits was published for consultation in summer 2025 and a subsequent version will be published in due course.

Also, in March this year we published a Land Use Framework for England which set a vision for multifunctional land use. To achieve that vision, we recognise that in some circumstances, it may make sense for multiple revenue streams to be combined on the same area of land. We are considering how best to support this vision while maintaining environmental integrity and intend to set out our position later this year as part of the forthcoming response to the recent consultation on Voluntary Carbon and Nature Markets.
