In Your City

Cities are on the frontline of the global climate emergency. If we fail to act now, we face even more devastating consequences – extreme high temperatures, flooding of oceans and rivers, blackouts, droughts, food shortages and frequent global pandemics.

The science is clear that there is still time for us to act, and cities, citizens, businesses, and national governments working hand in hand can make a difference.

As cities and local governments recover from COVID-19, implementing green climate solutions can help accelerate economic recovery leading to a more healthy, equitable, and sustainable future.

Many mayors and city leaders are already leading the way by putting in place measures to rapidly decrease emissions and halve them (or better) by 2030. We’re inviting every city, town and community on earth to join us on this journey:

Getting involved as a mayor or city official

Mayors of the world’s cities have been some of the strongest champions of the Paris Agreement and have been committed to delivering on its highest ambition – to keep global temperature rise below 1.5°C.

In addition to continuing the work you are already doing in your city, here’s how your city or local government can join Countdown and help lead a worldwide movement to accelerate solutions to address the climate crisis.

Activate through Countdown

Through events on 10.10.2020 and in 2021 around the Summit, Countdown will provide a global stage to showcase and accelerate the climate solutions that are already underway in your city. Countdown offers the opportunity for your city and mayor to:

  • Engage constituents and local communities on climate issues and kickstart a citywide conversation
  • Share innovative climate solutions and raise your city's profile across a global audience
  • Receive training from TED and our partners on how to communicate effectively about the climate solutions underway in your community
  • Join us on 10.10.2020

    Connect with local TEDx organizers to see what is already being planned in your city and what role you can play in these events – from your mayor attending to a possible speaking opportunity. Learn more about 10.10.2020.To find out if there is a TEDx Countdown event taking place in your city, please contact us.

  • Share your city’s climate story

    Countdown wants to amplify the incredible work happening in cities and communities around the world. Let us know how your city is taking action to address the climate crisis: share your story here.

Accelerate climate action in your city and community

There is an incredible amount of expertise available to cities, towns and communities that are striving to deliver on the Paris Agreement. Here’s where to start:

Learn and share what’s working

Many towns and cities are working together through local and international organizations to share best practices and accelerate climate action. Consider becoming more active with one of these leading organizations:

Join the Race to Zero

Race To Zero is a global campaign to mobilize leadership and support from businesses, cities, regions and investors for a healthy, resilient, zero carbon recovery that prevents future threats, creates decent jobs, and unlocks inclusive, sustainable growth.

The objective is to build momentum around the shift to a decarbonized economy ahead of COP26, where governments must strengthen their contributions to the Paris Agreement. Joining the Race will send governments a resounding message that business, cities, regions and investors are united in meeting the Paris goals and building a more inclusive and resilient economy.

If your city is ready to join the Race, find out how.

Increase your ambition

If your town or city hasn’t yet made any commitments to climate action, then committing to The Global Covenant of Mayors for Climate & Energy is a great place to start.

If your town or city is already taking action, check out these resources that can help you increase the scale of your work already underway.

Get in touch

If you work for a city or local government and would like more information on the resources available to cities and towns and advice on how to accelerate the actions underway, contact us.

Getting involved as a resident or community member

Whether you live in a large city or a small community, your voice and your choices matter. In addition to making changes in your daily life to reduce your personal carbon footprint, you also have an important role to play in making sure your city, town or community is taking the action needed to tackle the climate crisis. In addition, your voice is even louder and more powerful when combined with other citizens.


    Thousands of towns and cities around the world have made commitments to deliver on climate action. Find out where your community stands.
