About the UKAID CAI Programme

Supported by UK government funding through the Urban Climate Action Programme, C40’s UKAID Climate Action Implementation (CAI) Programme expands support for 15 C40 cities in Africa, Latin America and Southeast Asia in implementing ambitious climate action plans.

Between January 2022 to December 2025, C40 is providing tailored technical assistance and capacity building to support city-led efforts and projects to develop low-emission public transport systems, sustainable urban mobility planning, renewable waste management, energy efficiency in buildings, climate-smart buildings codes, and incorporate climate action into city governance, planning and decision-making structures.

From 2018 to 2021, C40 provided technical assistance and resources to 35 cities to develop climate action plans that effectively reduce greenhouse gas emissions and enhance climate resilience. Accra, Addis Ababa, Dar es Salaam, Johannesburg, Lagos, Nairobi, Tshwane, Bogotá, Guadalajara, Medellín, Mexico City, Lima, Jakarta, Kuala Lumpur and Quezon City were selected to receive the UKAID CAI Programme funding by the UK Department of Business, Energy and Industrial Strategy (BEIS) and UK Foreign, Commonwealth and Development Office (FCDO), based on input and expertise provided by C40.

Programme updates will be published on this web page regularly; jump to Africa, Latin America and Southeast Asia for updates from each city.
