Ardian and Societe Generale Launch €100 Million Nature-Based Solutions Partnership Targeting 85 Million Tonnes of Carbon Sequestration

Ardian and Societe Generale have announced a nature-based solutions equity partnership in which Societe Generale will invest €100 million as anchor investor in Ardian's Averrhoa NBS fund while acting as financial advisor through Societe Generale Investment Solutions to support fund structuring and deployment. The SFDR Article 9 impact fund, managed by Ardian's Infrastructure team in partnership with aDryada Advisory, is dedicated to investing in reforestation, wetland restoration and mangrove restoration projects aimed at protecting biodiversity while enabling carbon sequestration through natural sinks. The fund targets 85 million tonnes of carbon sequestration over 40 years, with projects designed to deliver climate mitigation benefits alongside preservation of water resources, improvement of soil and air quality and support for local ecosystems and communities.

 

The Investment Case for Nature-Based Solutions

 

Nature-based solutions are gaining significant traction as an investable asset class as corporate net-zero commitments and mandatory sustainability reporting frameworks create growing demand for high-integrity carbon removal and biodiversity protection instruments. The Averrhoa NBS fund targets the preservation and restoration of natural ecosystems that simultaneously deliver carbon sequestration, biodiversity protection and community development benefits, addressing the multidimensional value proposition that distinguishes the highest-quality NBS investments from simple carbon offset projects. Mathias Burghardt, Executive President and Chief Executive Officer of Ardian France, said Ardian is establishing itself as a key player in nature-based solutions by developing carbon capture projects that address climate challenges while restoring natural ecosystems and biodiversity, and that the initiatives are designed to deliver lasting benefits to local communities while meeting growing demand for solutions supporting net-zero ambitions.

Anne-Christine Champion, Co-Head of Global Banking and Investor Solutions at Societe Generale, said nature-based solutions are an emerging investment area where robust frameworks and long-term approaches are essential. She described the partnership as reflecting a shared conviction about how this market needs to develop, with a focus on large-scale, well-structured projects supported by strong underlying demand. The emphasis on scale and structure reflects a deliberate positioning of the fund as an institutional-grade vehicle rather than a project-level credit mechanism, targeting the governance standards and transaction sizes that allow corporate buyers and financial institution investors to commit capital with confidence in the integrity of outcomes.

Partnership Structure and Complementary Capabilities

 

The combination of Ardian's infrastructure investment expertise and Societe Generale's project financing, structuring and nature-related transaction advisory capabilities creates a partnership designed to address the full range of challenges in developing NBS projects at institutional scale. Infrastructure-grade project development requires capabilities spanning site identification, ecological assessment, community engagement, legal structuring, carbon methodology selection and long-term monitoring, none of which can be easily assembled by a single organisation without relevant experience across all dimensions. Ardian's infrastructure team brings the project development and long-term asset management capability while Societe Generale's structured finance expertise addresses the financial engineering needed to create investable instruments from what are inherently long-duration, complex assets.

The aDryada Advisory partnership adds specialist ecological and NBS project development expertise to the investment team, providing the scientific and operational depth needed to identify, structure and monitor reforestation and wetland restoration projects that meet both carbon sequestration targets and biodiversity outcomes. The 40-year investment horizon implied by the carbon sequestration target reflects the genuine long-term nature of NBS projects, where forests and wetlands take decades to reach the productivity levels that maximise both carbon storage and ecosystem service delivery. Investors and partners with the patience and institutional capability to manage assets over this timeframe are genuinely rare, making the Ardian and Societe Generale combination a credible vehicle for the asset class.

 

The Role of Anchor Investment and Market Development

 

Societe Generale's €100 million anchor investment provides the cornerstone capital that validates the fund to subsequent investors and demonstrates institutional conviction in the strategy at a stage when NBS as an asset class is still establishing its commercial track record. Anchor investments in first or early-vintage funds play a critical market development role by signalling quality to the broader investor universe and providing the initial capital base needed to begin deploying into projects that generate the track record required for larger subsequent fundraises. Champion explicitly framed the partnership as contributing to the development of nature-based solutions as an investable asset class, positioning the Societe Generale commitment as a market-building initiative alongside its direct financial return objectives.

The Article 9 SFDR classification places the fund at the highest level of European sustainable finance regulation, requiring that sustainability is the fund's core investment objective rather than a secondary consideration. This classification provides a credible regulatory anchor for the fund's sustainability claims and makes it accessible to the growing pool of institutional capital seeking Article 9 products for portfolios with strict ESG mandates. The combination of SFDR Article 9 status, anchor investor credibility and a 40-year carbon sequestration target positions Averrhoa NBS at the quality end of the NBS investment spectrum at a time when market scrutiny of greenwashing in voluntary carbon markets is intensifying.

Outlook for Nature-Based Solutions as an Institutional Asset Class

 

The Ardian and Societe Generale partnership reflects the broader maturation of nature-based solutions from a niche voluntary carbon market activity into a recognised institutional infrastructure asset class with dedicated fund vehicles, rigorous governance frameworks and creditworthy anchor investors. Whether Averrhoa NBS can achieve its 85 million tonne carbon sequestration target over 40 years will depend on the quality of project selection, the effectiveness of ecological restoration methodologies and the robustness of long-term monitoring and verification systems. Sustained delivery of both carbon and biodiversity outcomes would strengthen the credibility of NBS as an asset class and provide a reference vehicle for the institutional capital that needs to flow into nature protection at the scale that global biodiversity commitments require.

The convergence of corporate net-zero demand for high-integrity carbon removal, mandatory biodiversity disclosure under the TNFD framework and growing recognition among financial institutions that nature-related risks are material to portfolio performance creates structurally favourable conditions for NBS fund strategies to attract increasing institutional capital. The next phase of the NBS market will be defined by whether the governance and accountability frameworks being developed by the TNFD, the Voluntary Carbon Market Integrity Initiative and the Integrity Council for the Voluntary Carbon Market can establish the standardised quality benchmarks that institutional investors need to allocate at scale. The Ardian and Societe Generale partnership is a significant step toward demonstrating that these standards can be met in practice.
