## Summary

The Department for Energy Security and Net Zero (DESNZ) is planning a public procurement process titled “Climate Ambition Support Alliance (CASA)”. This initiative, currently in the planning stage, focuses on foreign economic-aid-related services, aimed at providing a comprehensive capacity-building programme for developing countries in international climate negotiations. The procurement is classified under the CPV code 75211200. Key engagement ends by 23rd April 2026, with a significant online market engagement event already scheduled for 23rd January 2025. DESNZ, based in London, is driving this initiative, impacting areas such as British Overseas Territories, Channel Islands, Europe, Isle of Man, Rest of the World, and the United Kingdom.

This tender represents a promising opportunity for businesses involved in providing technical, legal, and logistical support services, particularly those with an interest or existing capabilities in the field of international climate negotiations. With a specific focus on enhancing the influence of the most climate-vulnerable and least developed states, the initiative provides a significant platform for small and medium-sized enterprises (SMEs) to partner in a project that aligns with the UK's strategic climate goals. Businesses with expertise in training and capacity-building programmes would be particularly well-suited to compete for this tender.

## Notice

The Climate Ambition Support Alliance (CASA) programme will work through secondary providers to provide training, in addition to technical, legal and logistical support for developing country negotiators, in order to build the capacity of the least developed and most climate vulnerable states to participate in the international negotiations process and be more effective in influencing its outcomes, whilst at the same time facilitating the UK's core negotiations objectives. CASA builds on the work done to date by the Negotiations Support Programme (and before that CDKN), but represents a new programme intended to provide an enhanced capacity building offer, with the ability to be more responsive to technical assistance requirements within the international climate change negotiations and related fora as they emerge.
