Nature-as-a-Service: Making nature regeneration a sector in our economic model

The accelerating biodiversity crisis exposes a structural weakness in current biodiversity finance: most mechanisms rely on ex-ante project models that estimate future ecological outcomes, generate uncertainty and integrity risks, and produce forms of impact (e.g., carbon or abstract biodiversity metrics) that consumers struggle to relate to. This combination erodes trust, limits societal mobilisation and fails to attract meaningful private capital.

We propose an alternative architecture that treats whole-ecosystem regeneration as an economic activity, monetised through ex-post, measured and quality-rated ecological gains issued as Nature Gain Rights (NGRs). Drawing on ecological science, financial market design and empirical work in landscapes such as the Borana Conservancy, we show that realised increases in ecosystem mass (“biomass”) provide the universal quantity unit for nature recovery. Biomass gains—measured via remote sensing–based allometric modelling and field validation—represent the ex-post increments of primary producer mass (vegetation and water) that anchor each NGR vintage.

A complementary biodiversity quality rating evaluates ecological composition, structure, functioning and resilience. Grounded in Noss’s Hierarchy and Essential Biodiversity Variables, this rating acts as the quality marker, analogous to purity grades in commodity markets or ratings in fixed-income markets. Separating quantity (biomass gain) from quality (ecosystem condition) enables transparent, auditable and comparable nature outcomes.

This architecture creates a self-reinforcing economic value chain: Nature-as-a-Service enterprises regenerate ecosystems; independent specialists measure and rate ecological outcomes; a financial market-compliant exchange trades and records NGRs; and corporate buyers purchase NGRs to make verifiable, place-based nature-positive claims that enhance product differentiation, consumer engagement and revenue growth.

Crucially, this corporate demand for revenue-generating nature-positive claims—rather than investor ESG commitments—creates the price signals that make large-scale regeneration investable for yield-seeking capital. In this way, NGR markets replace fragmented project funding with continuous production of ecological improvement, enabling scale, repeatability and long-term investment.

NGRs thus support the emergence of a Nature-as-a-Service economic sector in which professionally regenerated ecosystems supply credible, measurable nature-positive contributions. By aligning scientific measurement with business incentives, ex-post nature markets offer a scalable pathway to mobilise private capital and expand biodiversity-positive economic activity.
