About the UCAP CAI Programme

Supported by UK government funding through the Urban Climate Action Programme (UCAP), C40’s UCAP 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, sustainable waste management, renewable 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 UCAP 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.

Through UCAP CAI, we support cities in prioritising fairness and inclusivity in climate policies and urban decisions. C40 helps cities integrate equity and inclusion by involving marginalised groups in decision-making and ensuring benefits are distributed equitably. Examples include supporting Bogotá’s electric bus fleet operated mostly by women, improving worker engagement in waste management in Dar es Salaam, and ensuring accessibility criteria are considered when selecting public buildings in Jakarta.

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

The high-impact implementation actions for cities in the African region will deliver renewable energy, green buildings, sustainable waste management and climate mainstreaming to help these cities to secure a greener future.

Delegates and representatives from the cities of Accra, Addis Ababa, Dar Es Salaam, Johannesburg, Lagos, Nairobi and Tshwane participated in the regional launch of CAI Programme on 19 July 2022 in Johannesburg, hosted by Mpho Phalatse, the former Executive Mayor of Johannesburg and former C40 Vice Chair for Africa.

Latin America

C40 is providing tailored technical assistance and capacity building to Bogotá, Guadalajara, Lima, Medellín and Mexico City, in support of city-led efforts to improve energy efficiency and transportation systems and to incorporate climate considerations into planning and governance.

Formal events to launch the new collaboration have occurred in each city. The events were officiated by the respective mayors or their municipal secretaries, including Mayors Rafael López Aliaga of Lima, Daniel Quintero of Medellín, Claudia López of Bogotá and Pablo Lemus of Guadalajara, as well as Mexico City’s Secretary of Mobility Andrés Lajous.

Southeast Asia

C40 is collaborating with the local governments of Jakarta, Kuala Lumpur and Quezon City to implement transformational climate actions to enhance energy efficiency, expand the adoption of renewable energy in government-owned, commercial, and residential buildings, and develop climate mainstreaming activities. Watch the video above to learn how these cities are turning strategies into wider implementation to achieve carbon neutrality by 2050.

The programme launch ceremonies took place in August and September 2022 and were officiated by three mayors in the region: the Honourable Mayor of Quezon City, Josefina ”Joy” Belmonte, the former Governor of Jakarta, Anies Baswedan, and the former Datuk Bandar (mayor) of Kuala Lumpur, YBhg.
