MAYOR OF LONDON, SADIQ KHAN, APPOINTED SPECIAL ENVOY TO FOSSIL FREE CITIES

The role of cities in the global just transition 

Cities are on the frontlines of the climate emergency, and they are also where the most innovative solutions are being pioneered. As Special Envoy, Mayor Khan will champion the role of cities and subnational governments in shaping global climate policies, ensuring they have a seat at the table in the urgent effort to phase out fossil fuels equitably, and finance a more just, sustainable future. Over 135 cities and subnational governments, including London, California, and 17 national capitals, have already endorsed the Fossil Fuel Treaty proposal.

Cities face particular risks and vulnerabilities to the climate crisis, while also exacerbating it by simultaneously consuming a high proportion of the world’s energy and generating the majority of greenhouse gas emissions. The world continues to rapidly urbanise, and cities are not only home to the majority of the world’s population, but with that, huge drivers of climate emissions. Urban areas are experiencing first hand the effects of intensive fossil fuel use and are facing threats to the health and wellbeing of their populations from extreme temperatures and air pollution, to increased risks of disease and reduced availability of fresh water and food among many others. As a result, cities are in a unique and critical position when it comes to tackling the climate crisis -  they are central actors in the delivery of climate action and they have the opportunity to demonstrate the bold leadership needed to transform our societies so that they are fit for the future. 

London is leading by examples
  • CLEAN AIR & NET ZERO

    ULEZ and other policies have cut pollution and put London on track for net-zero by 2030.

  • FOSSIL FUEL DIVESTMENT

    Mayor Khan led efforts to divest £10bn in pension assets from fossil fuels and boost green investments.

  • GLOBAL LEADERSHIP

    As C40 Co-Chair, he’s helped cities worldwide cut ties with fossil fuels and share solutions.

  • EQUITY IS CENTRAL

    Clean air, green jobs, and climate resilience must benefit everyone, especially vulnerable communities.

QUOTES FROM THE SPECIAL ENVOY ANNOUNCEMENT

  • "Cities are on the frontlines of the climate crisis, but they are also where the solutions are being forged. As Special Envoy, I am committed to ensuring that cities and subnational governments are not just heard but actively involved in shaping the global response to this crisis. The Fossil Fuel Treaty Initiative represents a necessary step toward a sustainable, healthier future for all."

    SADIQ KHAN
    Mayor of London and C40 Co-Chair

  • "Cities are the beating heart of climate action, and Mayor Khan’s leadership in London has set a gold standard for what is possible when bold, visionary leadership meets unwavering commitment. As Special Envoy, he will amplify the voice of cities on the global stage, ensuring the Fossil Fuel Treaty is not just a framework but a catalyst for transformative change that reflects the urgent needs and aspirations of local communities. This is more than a step—it’s a leap toward a more just, sustainable, and fossil-free future for all."

    TZEPORAH BERMAN
    Co-Chair and Founder, Fossil Fuel Non-Proliferation Treaty Initiative

  • "Mayor Khan’s leadership in London has demonstrated that bold climate action is not only possible but transformative. His appointment as Special Envoy is a testament to the critical role cities must play in the global effort to phase out fossil fuels. At C40 Cities we have placed ending the use of fossil fuels at the very core of what we do, and we are proud to stand with Mayor Khan and the Fossil Fuel Treaty Initiative. Cities are the doers of climate action and now is our time to create a better, safer future for urban residents everywhere."
