## Summary

The procurement process for "Climate Services for a Net Zero Resilient World (CSN0W2)" has been completed by the Department for Energy Security & Net Zero, located at 55 Whitehall, London. This initiative focuses on research services within the climate resilience sector and operates from a central government public authority classification. The procurement was conducted under an open procedure, culminating in the award of the contract to Ove Arup & Partners Limited. The project involves integrating climate change mitigation and adaptation strategies to promote resilience, particularly for net zero and the Clean Power Mission within the UK. The contract began on 3rd June 2026 and will run through to 31st March 2030, reflecting the buying organisation’s commitment to long-term environmental and energy targets.

This procurement offers significant growth opportunities for businesses specialising in climate science, energy adaptation, and cross-sectoral policy integration. Firms well-versed in multi-disciplinary approaches, including climate risk assessment, economic analysis, and knowledge dissemination, are particularly suited to benefit from this contract. It underscores a call for a consortium of suppliers to deliver the breadth of expertise required, opening avenues for both large corporations and SMEs ready to collaborate on delivering comprehensive climate services. Such a project not only enhances business profiles within the governmental sector but also offers substantial contributions toward the ambitious net-zero targets, intertwining business success with environmental stewardship.

## Notice

DESNZ is seeking to procure a contractor to provide climate services focusing on the integration of mitigation and adaptation to build resilience and de-risk the delivery of net zero and the Clean Power Mission. This will build on the successful CS-N0W programme, though with a new research scope. It will include research on: Metrics and thresholds to measure and monitor UK climate resilience . Assessing the climate resilience of UK mitigation policies and pathways, and levers and barriers to implementing resilience measures. Cascading hazards and system linkages (with a focus on the UK built environment) . Modelling global mitigation and business-as-usual pathways to better understand the benefits, costs, and risks of action to reduce warming to 1.5degC or below after exceeding it as well as the impacts that are avoided and the consequences of inaction. The programme will take a whole-system approach to climate resilience and energy security, considering cross-sectoral and cross-border climate impacts on the energy and net zero system. A knowledge integration work package will provide agile policy support. The programme will require expertise in assessing climate risk through a mixed-method and multi-disciplinary approach, across climate science, built environment and energy adaptation, economics and social science. Methods could include evidence syntheses and literature reviews, data analysis and scenario development, knowledge integration and dissemination. DESNZ anticipates a consortium of suppliers will be needed to cover the breadth of expertise required. Outputs are likely to include reports, on-call advice and briefings, seminars and teach-ins, workshops, and scientific support. The research will be co-designed with policy focal points to inform specific policy areas and will have built-in flexibility to respond to emerging policy needs.
