The most powerful innovation happens locally. 🌍

For over a decade, our Bloomberg CityLab Summit has united mayors and urban leaders from hundreds of cities to share solutions with global impact.

This year, we’re heading to @MADRID from April 27 –29. 🇪🇸

Stay tuned for further details!

[Bloomberg Philanthropies @BloombergDotOrg]

Cities can’t deliver bold results without the freedom to test bold ideas. When mayors can think big, test cheap, and learn fast, local solutions can scale into global breakthroughs.

Aparna Ramanan, who leads our Mayors Challenge program, shares why cities must be empowered to experiment, in @GOVERNING: https://t.co/zthDMCrrH8

📢 We’re expanding our Youth Climate Action Fund to support up to 300 more municipalities to engage youth in designing, developing, and implementing local climate solutions in their cities.

Already, this work with 100 city halls has brought together 100,000+ young residents who’ve planted 150,000 trees, created 250 new green spaces, cultivated 3,000 gardens, collected 350,000 pounds of trash and recyclables, and more. And we're just getting started. 🌎

In the @CityofAtlanta, a solution to street homelessness—a challenge facing cities nationwide—is getting results.

That’s why as part of the Bloomberg Cities Idea Exchange, our team took municipal officials to see @andreforatlanta's work up close—and the inner-workings of his team’s intervention.

Now, from @loveshreveport1 to @CityofMGM, city halls across the U.S. are beginning to adapt this local blueprint—bringing learnings home they are putting to work for their residents.

In a world where parties, prime ministers, and presidents have long dominated the global stage, the spotlight is increasingly turning to a new group of leaders: mayors. As mayors continue to stand on the frontlines of our biggest challenges, we need to make sure they have the right tools and resources to succeed: https://t.co/7G4gIjhPea

In their own words: meet the Bloomberg LSE European City Leadership Initiative's inaugural class of mayors.

[James Anderson @JamesAnderson]

The Bloomberg LSE European City Leadership Initiative mayors spent the week with the continent’s fiercest public innovation minds — from @MazzucatoM to @geoffmulgan to @DavidHalpernCBE to our terrific partners at @LSECities and @TheHertieSchool.

Now, they head back to their city halls to put these lessons to work for their residents.

Here's more on the week from The Urbanist: https://t.co/PGbSrciUyp

[Bloomberg Philanthropies @BloombergDotOrg]

When mayors have the capabilities they need to lead, the world moves forward.

Now, through the Bloomberg LSE European City Leadership Initiative—the first-ever professional leadership program for Europe’s mayors and top municipal officials—city halls across the continent will be equipped with the skills, strategies, and network to succeed and drive progress on the issues their residents care most about.

Kicking off their work this week, we can’t wait to see all that our inaugural class of mayors—and their local governments—do to improve people’s lives.

[Steve Rotheram @MetroMayorSteve]

Strong nations are built on strong regions.

Liverpool City Region proves that progress comes when power’s shared, not hoarded.

That's why it's great to see @BloombergDotOrg backing city leadership through the Bloomberg LSE Initiative.

Give mayors the tools, and we’ll deliver.

[Bloomberg Philanthropies @BloombergDotOrg]

Strong mayors need strong city halls—and strong city halls move communities forward.

The inaugural class of 30 mayors and 60 officials in the Bloomberg LSE European City Leadership Initiative—the first-ever professional leadership program for Europe’s mayors and top municipal officials—represents 17 countries across the continent and more than 21 million residents.

They will receive world-class support to build the skills, strategies, and networks they need to lead: https://t.co/JuCAvapMCs

[James Anderson @JamesAnderson]

The measure of a country is not how tightly power is held at the center, but how widely progress is felt at the edges.

That is why the launch of the Bloomberg LSE European City Leadership Initiative matters.

Coming to a city hall near you: local government will be where human-centered AI meets the street—and shows what it can do.

Great speaking with ⁦@politico’s⁩ ⁦@StevenOverly⁩ on all things @BloombergDotOrg City Data Alliance, mayors, and more: https://t.co/ijg8lMvSWD

[James Anderson @JamesAnderson]

We launched GovEx over a decade ago to fill a critical gap: no one was helping municipalities build the internal capacity to use data to improve residents’ lives. Today, GovEx begins an exciting new chapter under new leadership. Take a look!

[James Anderson @JamesAnderson]

Local governments can—and must—be more than they are. That means putting residents at the center, harnessing ideas from every corner of a city, and turning energy into solutions.

Great talking with Chuck Marohn at @StrongTowns about how @BloombergDotOrg is building innovation inside city halls, and how his org is driving bottom-up change across America: https://t.co/m9bnPOLWpJ

Meet Bailey Siber, a Bloomberg Harvard City Hall Fellow in @cityofokc.

During her Fellowship, she helped launch the City’s first innovation team, advanced initiatives to reduce homelessness, and improved data governance—helping to upskill frontline staff on ethical AI use. Now, she’s taking her impact even further, stepping into the role of Chief of Staff for Mayor @davidfholt.

Here’s to Bailey and the many City Hall Fellows working with the Bloomberg @CenterforCities to bring @BHcityleaders' tools, practices, and platforms to drive progress in municipalities across the country.

[Accelerator For America @USAccelerate]

State and local leaders are stepping up to tackle the housing crisis—with bold moves like P3s and land use reform. But there's more to do. The National Housing Crisis Task Force’s Action Plan offers a roadmap forward. #HousingInnovation #affordablehousing

Effective, imaginative government is an inside job — and the Innovation Teams we support worldwide help build that engine inside city halls.

From @LpoolCityRegion to @AjuntamentVLC, @zaragoza_es to @VantaanKaupunki, 18 new European cities are joining a growing movement of local govs thinking differently, acting faster, and breaking through silos to deliver results residents can feel.

[Liverpool City Region @LpoolCityRegion]
