Berlin may be one of Europe’s greenest and most water-rich capitals, but its rivers and canals don’t always look the part.

That’s where ALLES IM FLUSS steps in. This Berlin-born initiative is bringing citizens, creatives, and organizations together to clean up the city’s waterways and riverbanks—while teaching Berliners how to protect them in the long term.

In 2025, Keep Britain Tidy and Litterati completed the UK’s most ambitious cigarette litter study ever, tracking pollution across more than 5,000 locations and two years of interventions. This wasn’t just awareness. It was behavior change, backed by AI, on-the-ground action, and sharp strategy.

Big goals can start with small actions. Whether you're organizing a full-day city clean-up with students or a solo plogging run: your action matters. And when thousands of those actions come together—all shared under the LCUE flag—they spark something more than clean streets: they spark a cleaner culture.

 In Berlin, 27,000 bins are emptied 7.4 million times a year.
