Barcelona · Streets
Give a neighborhood more room to live
Superblocks. Barcelona reorganises street space to put people and public life at the centre of neighborhood design.
Try locally
Pilot one small area with residents, shops and access groups. Plan loading, emergency access and step-free routes before changing traffic.
Measure the difference
Traffic inside and on boundary streets, accessible journeys, pedestrian use and resident feedback.
Before scaling
A quieter interior should not simply move pollution or difficult journeys to neighboring streets.

Turn schoolyards into cooler shared spaces
Oasis schoolyards. Paris schoolyard projects combine vegetation, more permeable surfaces and attention to children’s use of outdoor space.
Try locally
Start with one school. Invite pupils, staff and accessibility groups to map heat, shade and play before drawing a design.
Measure the difference
Shade coverage, surface temperature, rainwater performance and how different children use the space.
Before scaling
Budget for watering, maintenance and supervision, not just construction.

Make room for heavy rain
Cloudburst planning. Copenhagen plans for extreme rain across the city, including surface routes and public spaces that can help manage water.
Try locally
Ask qualified drainage engineers to map one catchment and identify where public-space improvements could support the wider flood plan.
Measure the difference
Flood exposure, drainage performance, maintenance needs and downstream effects.
Before scaling
Water crosses project boundaries. A local change must fit the whole catchment and local engineering requirements.

Make useful city data easier to reuse
Open geographic data. Helsinki publishes geographic data and participates in Helsinki Region Infoshare with neighboring cities.
Try locally
Publish one useful, non-personal dataset with a clear licence, owner, update schedule and a plain-language example.
Measure the difference
Freshness, accessibility, documented reuse and the time saved answering repeated information requests.
Before scaling
Open data requires quality and privacy review; publishing a file alone does not make it useful.

Treat water reuse as a long-term system
NEWater. PUB’s NEWater programme purifies treated used water using advanced treatment, including membranes and ultraviolet disinfection.
Try locally
Commission a professional feasibility study covering demand, treatment, regulation, energy and public communication.
Measure the difference
Water quality, reliability, energy use and the share of suitable demand served.
Before scaling
This is an infrastructure case study, not treatment instructions. Local water authorities and qualified engineers must assess suitability.

Buy for repair and reuse
Circular economy programme. Amsterdam’s circular approach seeks to keep materials and products in use and reduce waste.
Try locally
Choose one procurement category. Compare repair, reuse and new purchases using a simple inventory and whole-life cost assessment.
Measure the difference
Items repaired or reused, material use, service life and total cost.
Before scaling
Check local supplier capacity, safety standards and procurement obligations before scaling.

Reconnect people with an urban stream
Cheonggyecheon restoration. Seoul’s Cheonggyecheon restoration ran from 2003 to 2005, bringing a covered stream corridor back into public life.
Try locally
Study a corridor’s water, ecology, transport and business needs together, with people who use it every day.
Measure the difference
Accessible visits, ecological condition, operating costs and effects on nearby businesses.
Before scaling
Restoration can require substantial water management and relocation decisions; address displacement and maintenance openly.

Connect shade with everyday journeys
Green corridors. Medellín’s green corridors combine urban planting with ongoing care by gardening teams.
Try locally
Choose a hot walking route to a school, stop or clinic. Select locally suitable planting and fund care from the beginning.
Measure the difference
Plant survival, shade, temperatures at consistent locations and accessibility of the route.
Before scaling
Tree survival, water needs and local ecology matter more than copying a planting palette from another climate.
