7 proven strategies cities are using to clean the air.
With the right mix of planning, policy, and investment, they can make a real dent in emissions — and a lot of them already are.
Here’s how:
1. Plan smarter, build better
Cities that focus on compact, mixed-use neighbourhoods (where homes, shops, and services are all close together) make it easier for people to walk, cycle, or use public transport. It’s a simple shift with huge impact — fewer cars, cleaner air.
2. Invest in clean, reliable public transport
Electric buses, metro systems, and well-connected transit networks don’t just reduce pollution — they make cities more liveable. Add in transit-oriented development (where new housing is built near transit stops), and it’s a win-win.
3. Bring in more green and blue spaces
Parks, trees, green roofs, wetlands — all of these help filter air pollutants and cool down cities. They're also just great places to be. Nature-based solutions aren’t just pretty; they’re practical.
4. Make buildings and energy systems cleaner
Tightening building codes and switching to renewable energy in urban infrastructure cuts emissions at the source. Energy-efficient buildings aren’t just good for the climate — they save money and improve health.
5. Fix waste systems
Open burning of waste is still a major issue in many places. Improving collection, boosting recycling, and shifting towards a circular economy can dramatically reduce harmful emissions.
6. Regulate industrial pollution
Tougher standards and better zoning can keep heavy industry from polluting residential areas. It's not just about moving factories — it’s about cleaner tech, smarter planning, and better enforcement.
7. Include air quality in climate action plans
Many cities are now tying clean air goals into their broader climate strategies. Amman, for example, has made air pollution a key part of its Climate Action Plan.
Bonus tip: use policy to make it stick
Legal tools matter. From congestion pricing and low-emission zones to regulating high-pollution vehicles, cities can use governance to lock in cleaner air for the long haul.
