11 City Climate Solutions Show Real Progress

Cities are solving climate change right now, and a groundbreaking new report has the proof.

Engineering consultancy Arup partnered with The Earthshot Prize to identify 11 climate solutions that cities have already tested and proven successful. These aren't distant promises or theoretical fixes. They're real programs cutting emissions and making urban life better today.

The report highlights actions cities can take immediately, from revolutionizing public transit to reimagining green spaces. Each solution comes with evidence showing it works in the real world, giving other cities a proven playbook to follow.

City governments control about 70% of global carbon emissions through their decisions on buildings, transportation, and energy systems. That means mayors and local councils have enormous power to drive climate progress without waiting for national governments to act.

The Ripple Effect

When one city proves a climate solution works, others take notice and adapt it to their own communities. This creates a cascade of positive change that spreads faster than top-down mandates ever could.

The Earthshot Prize, launched by Prince William, awards groundbreaking environmental solutions each year. By partnering with Arup's engineering expertise, they've created a practical guide that turns inspiration into action.

Cities from every continent contributed data to the report, showing that climate solutions work in diverse environments and economic conditions. A strategy that cuts emissions in Singapore can inspire adaptations in Stockholm or São Paulo.

The report comes as urban populations continue growing, with two-thirds of humanity expected to live in cities by 2050. The solutions cities choose today will shape the climate for generations.

Local leaders now have a clear roadmap showing that climate action and urban prosperity go hand in hand, proving we can build cities that are cleaner, healthier, and more livable for everyone.
