Have you seen one of these around your city?

Across our cities, hundreds of sensors are quietly collecting data that helps build healthier, more connected communities. Better data today means better air tomorrow.

Local leadership is powering global climate progress.

Congratulations to the winners of the 2025 @BloombergDotOrg Local Leaders Climate Awards, C40 cities Boston, Oslo, São Paulo, Beijing, Rio de Janeiro, Salvador, Quezon City, and @BreatheCities Sofia.

It was great to celebrate your achievements in energy transition, clean transport, infrastructure, sustainable waste solutions, and air quality.

[Mete Coban @metecoban92]

We should never have normalised breathing dirty air.

That’s why London is a founding member of @BreatheCities - driving a global movement of cities committed to tackling toxic air pollution.

Inspiring to meet so many people in Rio who are making change happen on the ground.

[Mete Coban @metecoban92]

It was great to join the @BreatheCities street festival in Rio - standing alongside the people making change happen on the ground.

From London to Rio, we’re showing what’s possible when we reimagine our streets for people ✊🏼✊🏾
