The insurance workstream of the B4NZ Initiative focuses on positioning insurance as a core enabler of the net zero transition by strengthening how climate risk is understood, priced, and managed across financial systems. The programme works to integrate insurance more effectively into climate finance, resilience planning, and investment decision-making, ensuring risk mitigation supports the scale-up of low-carbon and nature-based solutions.

Insurance plays a critical but often under-recognised role in enabling transition finance by reducing investment risk, lowering capital costs, and improving the bankability of climate and nature projects. Despite this, insurance is frequently absent from climate finance frameworks, limiting the mobilisation of private capital and slowing deployment of long-term infrastructure and resilience investments. Key challenges include limited awareness among policymakers and financiers of insurance’s role, regulatory and structural barriers that constrain long-term underwriting, short product cycles that do not align with transition timelines, and gaps in data for emerging asset classes such as carbon markets and nature-based projects.
The workstream brings together insurers, banks, policymakers, agricultural stakeholders, and businesses to address these barriers through coordinated policy engagement and market development. Recent activity has included convening cross-sector coalitions focused on agricultural resilience and climate risk, alongside participation in ministerial and industry roundtables examining the future of agricultural insurance and financial security in the face of increasing climate volatility. This work builds on proposals developed with financial institutions, farming organisations, and insurers to strengthen risk modelling, improve access to protection products, and support investment in resilient and regenerative farming systems. 
Through engagement with UK policymakers and international partners, the initiative advocates for regulatory and policy frameworks that enable insurance products to align with long-term climate objectives and be embedded within national transition planning, including Nationally Determined Contributions and adaptation strategies. The programme also works with businesses and financial institutions to encourage earlier engagement with insurers in project design, helping improve risk assessment, strengthen supply-chain resilience, and reduce financing costs for clean technologies and nature investments.
By advancing collaboration between insurers and the wider financial ecosystem, the workstream aims to increase recognition of insurance as foundational climate infrastructure, support innovation in risk mitigation solutions, and enable scalable investment across sectors where climate risk currently constrains capital deployment.
