Net zero insurance is a descriptive label for the suite of insurance products that, taken together, support corporate net zero commitments — protecting against carbon credit invalidation and reversal, against project under-performance and against the legal and regulatory consequences of greenwashing or commitment failure.

“Net zero insurance” is not a single product line but a descriptor for the cover suite that responds to risks specific to a corporate net zero transition. At its core it comprises carbon credit invalidation and reversal cover, carbon delivery risk cover for forward removal contracts, and directors’ and officers’ and securities-related cover responding to greenwashing or commitment-failure claims. It is sometimes extended to include parametric covers for transition-technology under-performance.
The product label has gained currency since the publication of the SBTi Net Zero Standard (October 2021), the Race to Zero criteria (June 2022 update) and the UK Government’s Transition Plan Taskforce Disclosure Framework (October 2023). Each places quantitative obligations on signatories — particularly with respect to the limited and high-integrity use of credits — and creates the integrity surface that net zero insurance addresses.
Net zero strategies rely on a combination of internal abatement and the use of carbon credits, principally for residual emissions in the run-up to 2050 and for any beyond-value-chain mitigation in the interim. Credits are issued under voluntary standards including Verra (Verified Carbon Standard v4.7), Gold Standard for the Global Goals (v1.2), the American Carbon Registry, the Climate Action Reserve, Plan Vivo and Puro.earth for engineered removals.
The Integrity Council for the Voluntary Carbon Market published its Core Carbon Principles, Assessment Framework and Assessment Procedure on 29 March 2023, providing a quality benchmark on the supply side. The Voluntary Carbon Markets Integrity Initiative Claims Code of Practice (28 June 2023; v2 November 2024) governs the claims a buyer may make, and SBTi guidance increasingly distinguishes engineered durable removals from avoided-emissions credits.
The constituent products of a net zero insurance programme include carbon credit invalidation cover, reversal cover, non-delivery and forward delivery cover, political risk cover for credits sourced from emerging-market projects, and engineered-removal performance cover. Beyond the credit-specific covers, directors’ and officers’ policies respond to claims that the board has, in approving the net zero strategy or its communication, breached statutory duty; securities class action coverage responds to investor claims that strategy or progress has been misstated; and management liability covers respond to ESG-related regulatory investigation costs.
Specialist underwriters writing in the carbon-specific component include Kita Earth (Lloyd’s Lab Cohort 7, March 2022), CFC Underwriting (carbon credit invalidation product launched April 2023), Howden’s dedicated carbon insurance practice and Oka (founded 2023, Beazley Smart Tracker). D&O cover is provided by the broader London D&O market, with several insurers having published statements on the underwriting of ESG and transition risks.
Programme design is bespoke. Larger corporates often layer cover, with primary invalidation and reversal limits supported by excess layers and quota-share co-insurance for catastrophic loss; D&O cover is placed separately but coordinated to avoid coverage gaps in scenarios where commitment failure crystallises both credit-side and securities-side exposure.
Net zero commitments are now embedded in UK financial regulation. The Companies (Strategic Report) (Climate-related Financial Disclosure) Regulations 2022 (SI 2022/31), in force from 6 April 2022, require large companies and LLPs to make climate-related financial disclosures consistent with TCFD recommendations. The Financial Conduct Authority’s Listing Rules already required premium-listed issuers to disclose against TCFD; LR 9.8.6(8) was extended to standard-listed commercial companies. The Transition Plan Taskforce published its Disclosure Framework in October 2023, providing the structure for credible UK transition plans.
Advertising of net zero progress is policed by the Advertising Standards Authority applying the CMA Green Claims Code (20 September 2021). Recent ASA enforcement includes rulings against Lufthansa (December 2023), Etihad (October 2022) and HSBC (October 2022). The cumulative direction is that interim claims supported by avoided-emissions credits without qualification will fail; net zero communications must distinguish abatement from credits, and removals from avoidance.
Capacity in the carbon-specific component remains limited, with per-risk limits in the low tens of millions of pounds for nature-based projects and somewhat higher for engineered removals. D&O capacity for the largest UK corporates remains in the billions but is now subject to far closer underwriting scrutiny of climate strategy, transition plan credibility and the use of credits.
A FTSE 100 group with a 2040 net zero commitment under the SBTi Net Zero Standard structures a net zero insurance programme: a credit-side layer with invalidation and reversal cover across its retired offsets; a delivery-side layer for its long-duration engineered removal offtakes; and D&O and securities cover supplemented with greenwashing endorsements responsive to securities litigation following any future restatement of progress.
