Background
C40 is a network of nearly 100 mayors of the world’s leading cities, who are working to deliver the urgent action needed right now to confront the climate crisis, and create a future where everyone, everywhere can thrive. Mayors of C40 cities are committed to using a science-based and people-focused approach to help the world limit global heating to 1.5°C and build healthy, equitable and resilient communities. Through a Global Green New Deal, mayors are working alongside a broad coalition of representatives from labour, business, the youth climate movement and civil society to go further and faster than ever before.
C40’s team of 400+ staff is based in offices in London, in New York, Johannesburg, Singapore, Delhi, Rio de Janeiro, Copenhagen, Beijing and Paris, and individual staff based across 25+ different locations.
The strategic direction of the organisation is determined by an elected Steering Committee of C40 mayors, which is chaired by Mayor Sadiq Khan of London and Mayor Yvonne Aki-Sawyerr of Freetown. Three-term Mayor of New York City Michael R. Bloomberg serves as President of the C40 Board of Directors, responsible for operational oversight. A regionally diverse management team, led by Executive Director Mark Watts, leads the day-to-day management of C40. C40’s three core strategic funders are Bloomberg Philanthropies, the Children’s Investment Fund Foundation and Realdania.
Our international staff work with the C40 network under the leadership of city governments to deliver this mission. Using a data-driven approach, our team identifies and promotes the exchange of proven programmes and policies developed by cities; provides world-class research, technical expertise and access to key partners to deliver new programmes and policies with cities; and communicates cities’ individual achievements and collective leadership.

C40 Climate Solutions and Networks
C40’s Climate Solutions and Networks (CSN) team oversees six program areas focused on priority climate action sectors and interventions: Energy and Buildings; Transportation; Urban Planning; Food and Waste; Air Quality; and Climate Resilience. Under these program areas, CSN operates 16 different networks that facilitate city-to-city best practice sharing on specific climate action areas, such as clean energy or zero emission vehicles. The networks help cities replicate, improve and accelerate climate action to meet the goals of the Paris Agreement. These city-only working groups provide for honest knowledge and experience exchange, enabling cities to tap into the global expertise of their peers as well as connect with technical partners. Through networks, cities find opportunities to undertake joint projects in areas of mutual interest and benefit. C40 networks also amplify individual city solutions by providing a global platform for showcasing city success. The result is that cities' climate actions to reduce GHGs, air pollutants and climate risks are bolder, fairer, and more impactful than if they were to go it alone.
A number of these programs and networks also offer direct support to cities through technical assistance projects, training, tools, and resources, often in conjunction with other C40 teams and programs. The CSN team also supports cities to deliver on the mayoral commitments made through C40’s accelerators including, but not limited to the Renewable Energy Accelerator, the Green & Healthy Streets Accelerator, the Net Zero Carbon Buildings Accelerator, and the Pathway Towards Zero Waste, and Towards Zero Waste Accelerators. The C40 accelerators are statements of political leadership giving cities an opportunity to show leadership globally and locally.
The Energy and Buildings Programme supports cities to overcome barriers to the implementation of policies and programmes to deliver ultra-efficient buildings powered by renewables. The team delivers support to cities through a variety of methods: providing short periods of consultancy guidance to overcome specific barriers, developing city-led research projects, and hosting action-oriented workshops, all while leveraging the experience of and sharing lessons with city peers through C40’s four building and energy networks, as well as the Clean Construction Forum. The topics include energy efficiency in existing buildings and new buildings, including privately owned and city-owned buildings, as well as clean energy and embodied carbon of built infrastructure.
Regional Approach
Core to C40’s value and effectiveness is an ability to be responsive to the needs of all C40 cities and focus services and support on the areas of greatest opportunity for city action and climate impact – both at the individual city level and across our regional and global networks. Our regional management structure better enables C40 to leverage relationships between peer cities and technical and financial partners regionally and globally and to be more responsive to local needs and conditions.
To manage these efforts, C40 Regional Directors are positioned in seven regions: Africa, Europe, North America, South America, Southeast Asia and Oceania, East Asia and South & West Asia. The Regional Directors act as the ambassador for their regions, to ensure that the organisation can deliver effectively at a regional level considering specific geographic, cultural, language and other differences.
In Africa, the Regional Director in Africa is supported technically by the The Head of Implementation for Africa. The Head works very closely with all CSN teams to support the African region C40 cities in accelerating the implementation of the most impactful climate actions, and in facilitating learning from their peers across other C40 cities. A Deputy Regional Director for Africa, supports the Regional Director with managing the city engagement and relationship building in the region.
The successful candidate will need to be a quick learner who thrives in dynamic environments, a matrix management system and is skilled in building relationships across teams and coordinating across diverse groups of stakeholders. They will need to have a collaborative mindset and be adept at connecting people and organisations around a shared purpose and common goals.
They will need to be methodical in driving timely delivery and able to work independently with strong strategic thinking.
