Paris is de-paving and greening its 760 public schoolyards to create 'climate shelters'; a 2018–2023 EU-funded pilot instrumented 10 sites and measured perceived-temperature drops of 3–8°C, informing citywide rollout targeted for 2040.

Context

Under the Paris Climate Plan since 2017, the goal is to convert the city's 760 public pre-, elementary and middle-school playgrounds from asphalt to permeable, vegetated 'oasis' courtyards by 2040, removing impermeable surfaces and adding trees, planting beds and higher-albedo materials.

Activities

A pilot phase funded by the EU's Urban Innovative Actions (UIA) programme, from 2018 to 2023, instrumented and evaluated 10 schoolyards with field microclimate measurements.

Results

Published studies and preprints recorded perceived-temperature reductions of 3–6°C typically and up to 8°C during heat waves in the renovated pilot schoolyards, compared with unrenovated asphalt yards.

Conclusions

The rigorous instrumented evaluation covers only the 10 UIA pilot sites; the wider rollout to all 760 schools is a multi-decade target through 2040, and standardised outcome data across the full school portfolio is not yet available.

Implementation
Indicative cost
High (€500k–€5M) — EU UIA co-funded pilot (10 sites, 2018–2023) preceding a multi-decade citywide rollout to 760 schools by 2040.
Time to results
Long (> 3 years) — Programme launched 2017, pilot ran 2018–2023, full rollout targeted through 2040.

Conditions for success

  • EU Urban Innovative Actions co-funding for the instrumented pilot phase
  • Field microclimate measurement and evaluation informing citywide design before scale-up

Common failure modes

  • Standardised outcome data across the full 760-school portfolio is not yet available; rigorous evaluation is limited to 10 pilot sites
