30 cities have peaked greenhouse gas emissions.

Austin, Athens, Lisbon, and Venice join a group of 30 global cities in reaching major climate milestone.

30 of the world’s largest cities, representing 58 million citizens, have announced that their greenhouse gas emissions have peaked and are now going down fast.

The world’s leading scientists tell us that emissions must peak by 2020 and decline rapidly in order to prevent climate catastrophe. Leading cities like Austin, Athens, Lisbon, and Venice have already achieved this vital milestone, demonstrating to the rest of the world that a rapid and equitable low-carbon transition is possible.

At C40, our number one priority is helping mayors and city officials take climate action faster and farther than ever before. Today, we are proud to announce the launch of the C40 Knowledge Hub, a first-of-its-kind online resource to provide city leaders with insights, share practical experiences and outline tested approaches to inform and inspire greater climate ambition with real, on-the-ground results.

These 30 cities are proving that a different, sustainable way of life is possible. More exciting announcements to come this week – RSVP to the C40 World Mayors Summit Livestream to make sure you’re the first to hear the news.
