London has achieved the impossible: its air quality levels just met legal nitrogen dioxide limits for the first time. Experts said this would take 193 years, but under Mayor of @london.gov.uk @sadiqkhanlondon.bsky.social’s visionary leadership, it was accomplished in just nine years.

🌍 To meet global climate goals, national governments can’t work alone.

Are climate solutions boring?

At #ClimateWeekNYC, Mayor Aki-Sawyerr challenged that.

By engaging youth and empowering local communities, cities can make climate action effective and engaging by prioritising an equitable transition and addressing health and affordability.

Guadalajara is turning ambition into action on the ground:
🏛️ Mexico's first LEZ in its historic centre
🏢 Cleaner, low-emission public buildings
👩‍🔬 Good green jobs

These programme results from C40’s UCAP CAI, supported by the British Embassy in Mexico City, prove city leadership matters.

What Donald Trump said today at the United Nations is factually incorrect - it's disinformation. Climate change is not a hoax.

Share this to stop the lies spreading.
