Overview

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 1.5°C or below after exceeding it as well as the impacts that are avoided and the consequences of inaction.

Additional details

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.
