Over 40 ministers met today in Dubai in support of subnational climate action, joining the COP28 Presidency to announce a series of partnerships to accelerate the net-zero transition and climate resilience in cities.




The announcements span sectors including buildings, waste and resource management systems, urban water resilience, and urban nature restoration. They build on the 1 December launch of the Coalition for High Ambition Multilevel Partnerships for Climate Action (CHAMP) to include cities and regions in the design of federal climate commitments and strategies.




“Meeting the aims of the Paris Agreement and keeping 1.5°C within reach depends on the leadership and support of the world’s mayors and governors,” said Dr. Al Jaber, “That is why at COP28 we have empowered leaders and communities by launching CHAMP and working with organizations like UN-Habitat and Bloomberg Philanthropies to recognize and support the important roles cities and their leaders can play in addressing climate change."




Multilevel Action, Urbanization, Built Environment and Transport Day hosted the second Urban Climate Ministerial, co-organized with United Nations Human Settlements Programme (UN-Habitat), and the UN Climate Change High-Level Champion for COP28,and concludes a week of unprecedented mayoral and gubernatorial participation in the COP process. Brazil’s Minister of Cities, HE Jader Barbalho Filho, closed the meeting by announcing Brazil’s plans to widen participation and mobilization for the Ministerial at COP30.




The COP28 Presidency and Bloomberg Philanthropies partnered to deliver the Local Climate Action Summit (LCAS) (1-2 December), which saw over 500 subnational leaders join the summit portion of a COP for the first time. Nearly USD $500 million of new city-focused climate investment was also announced.




6 December outcomes include:






The Buildings Breakthrough




The Buildings Breakthrough, launched with the support of 27 countries, is led by France and Morocco. The partnership aims to make ‘near-zero and resilient buildings’ the new normal by 2030, addressing the fact that the building sector alone accounts for nearly 40 percent of global energy-related CO2 emissions, 50 percent of extracted materials, and one-third of global waste.






The Cement Breakthrough




The Cement and Concrete Breakthrough was launched by Canada and the UAE, along with an inaugural cohort of endorsing countries that include the United Kingdom, Ireland, Japan and Germany. The initiative strives to make clean cement the preferred choice in global markets, with near-zero emission cement production established and growing in every region of the world by 2030.






The Waste to Zero initiative




Waste to Zero[1] is a voluntary coalition made up of governments of all levels, NGOs, and the private sector to decarbonize the waste management sector and transform waste into resources[2]. Waste to Zero is an official initiative under the UAE’s ‘Year of Sustainability’ and spearheaded by the UAE Ministry of Climate Change and Environment (MOCCAE), Abu Dhabi Waste Management Company (Tadweer), and Roland Berger.






The Waste MAP




The Waste MAP is the first-ever global platform to use satellite monitoring to track and measure methane emissions from waste, developed by the Global Methane Hub[3], Google Foundation, Rocky Mountain Institute, Clean Air Taskforce (CATF), the Netherlands Institute for Space Research (SRON)/GHGSat, and Carbon Mapper. Local governments and NGOs can use the platform to identify and mitigate methane emissions before they become hazardous. The platform is set to go live in 20 global megacities that are collectively home to over 100 million people.




Two new programmes to accelerate the adoption of 15-minute city (15MC)/proximity planning policies and measure their impact



C40, a network of nearly 100 mayors of the world’s leading cities, is increasing actions to accelerate the adoption of the 15-minute City (15MC) - highly liveable, walkable, and people-oriented cities. The Green and Thriving Neighborhoods programme created in collaboration with Urban Partners provides deep support to more than 40 cities to help them turn the 15MC into reality through the implementation of concrete pilot projects. C40 also launched a tool to measure the impacts of 15MC with Novo Nordisk. The Healthy Neighborhoods Explorer, created with Novo Nordisk’s Cities will enable policymakers to measure how 15MCs significantly reduce emissions and offer residents better health.




The Generation Restoration project




Guided by the Paris Agreement and the Global Biodiversity Framework, the Generation Restoration[4] project (2023-2025) is currently supporting pilot projects to catalyze urban ecosystem restoration and emissions mitigation in eight world cities[5]. These cities include Douala (Cameroon); Dakar-Plateau & Thies (Senegal); Quezon City (the Philippines); Kochi (India); Sirajganj (Bangladesh); Samborondon (Ecuador); Mexico City (Mexico); and Manaus (Brazil).




Commitments to fossil fuel-free land transport




World transport systems are vital for people’s lives and livelihoods, with transport representing around 22 percent of global carbon emissions.




The COP28 Presidency, the UAE Ministry of Energy and Infrastructure, the International Transport Forum, and the International Energy Agency have come together to organize the first ever transport-energy ministerial at a COP. Working closely with key delivery partners, including the SLOCAT Partnership, the Air Transport Action Group and the UN Climate Change High-Level Champions team, the COP28 Presidency spotlighted key solutions to decarbonize the transport sector.




The sustainable land transport community, led primarily by the SLOCAT Partnership, agreed to mark the first ever World Sustainable Transport Day on 26 November 2023, and issued a call to action to double the share of energy efficient and fossil-free forms of land transport by 2030. Initiated by SLOCAT and REN21 jointly with IDDRI, Institute for Transportation and Development Policy (ITDP), International Association of Railways (UIC), International Union of Railways (UITP) and World Resources Institute (WRI), and endorsed by Chile and Columbia and 60 multi stakeholder organizations.
