Mirova has entered into agreements with independent carbon rating agencies BeZero Carbon and Sylvera as the voluntary carbon market shifts from a volume-driven model towards one centred on quality, integrity and measurable impact.
The move reflects growing scrutiny of carbon credits and the need to channel capital towards high-quality projects that demonstrate additionality, deliver durable emissions reductions or removals, and generate tangible co-benefits for biodiversity and local communities. In a recent position paper, Mirova underscored the importance of strengthening transparency and accountability across the market.
BeZero Carbon and Sylvera apply science-based methodologies that combine geospatial analysis, project documentation reviews and risk modelling to produce publicly available ratings. These independent assessments are intended to help investors better evaluate project credibility and direct funding to higher-impact climate solutions.
Mirova said the external ratings would complement its existing ESG and technical due diligence processes, adding an additional analytical layer to strengthen portfolio quality and reinforce confidence in the integrity of carbon credits linked to its investments.
Charlotte Lehmann, Managing Director of Carbon Strategies at Mirova, said the partnerships aim to mobilise capital at scale towards “the highest-quality climate and nature-positive solutions”, while providing clients with greater transparency and comparability.
Tommy Ricketts, CEO and co-founder of BeZero Carbon, said integrating independent ratings into investment strategies demonstrates a commitment to trust and transparency in scaling climate finance.
Allister Furey, CEO of Sylvera, added that as voluntary and compliance demand increasingly compete for supply, building positions around quality would create long-term competitive advantage and help establish stronger market infrastructure.
Mirova said it would use the external evaluations as an additional decision-making input alongside its ESG, technical, financial and impact due diligence frameworks, as part of efforts to strengthen standards and support the continued maturation of the voluntary carbon market.
