Citywide canopy = total canopy area ÷ city boundary area. Mean buffer canopy = average canopy % within 60m of each building. % above 30% = proportion of buildings meeting the 30% canopy cooling threshold.
UK cities use May 2026 data; most continental cities use summer 2024 heatwave data. Berlin uses a July 2025 composite; Sevilla uses a July 2023 heatwave composite; Hamburg uses a 2023–2024 summer median composite. See Methods for scene details.
† Leeds LST from a partially cloudy scene (14.4% cloud, 2024-07-30), so mean temperature is not representative of peak heat.
Total: ~5.1 million buildings across 25 cities. On average, 83.5% of buildings fall below the 30% canopy threshold.
Income-heat inequality (cities with equity data)
| City | Country | Equity data source | Canopy–heat ρ | Income–heat ρ | Key finding |
|---|---|---|---|---|---|
| Nice | France | Filosofi 200m (2019) | −0.81 | −0.54 | Strongest canopy–heat signal. Wealthy hillsides have canopy; coastal flats exposed |
| Bristol | UK | IMD 2025 (LSOA) | −0.64 | +0.10 | Strong canopy–heat link; deprivation–heat link weak |
| Toulouse | France | Filosofi 200m (2019) | −0.58 | −0.32 | |
| Munich | Germany | Zensus 2022 (100m) | −0.57 | +0.07 | Rent barely predicts heat; canopy strongly does |
| London | UK | IMD 2025 (LSOA) | −0.55 | +0.33 | Most deprived LSOAs significantly hotter |
| Lyon | France | Filosofi 200m (2019) | −0.51 | −0.41 | |
| Marseille | France | Filosofi 200m (2019) | −0.51 | −0.55 | Strongest income–heat link |
| Cologne | Germany | Zensus 2022 (100m) | −0.51 | +0.09 | |
| Berlin | Germany | Zensus 2022 (100m) | −0.46 | −0.09 | Rent barely predicts heat; canopy does |
| Birmingham | UK | IMD 2025 (LSOA) | −0.45 | +0.23 | |
| Paris | France | Filosofi 200m (2019) | −0.29 | −0.16 | Weakest signal: both rich and poor equally canopy-deprived |
Canopy–heat ρ: Spearman correlation between canopy % and surface temperature. Negative = more canopy → cooler (expected). Income–heat ρ: correlation between income/deprivation proxy and surface temperature. Negative (France) = lower income → hotter; positive (UK) = higher deprivation rank → hotter. Same relationship, different measurement direction.
No equity data available for: Spain (Barcelona, Madrid, Sevilla), Italy (Rome, Naples, Milan), Portugal (Lisbon, Porto), Greece (Athens, Thessaloniki), UK (Leeds, Liverpool, Newcastle).
Cool spots: dense areas that stay cool
Temperature gaps between shaded and exposed areas at similar dwelling densities (~50 dw/ha):
| City | Temperature gap | Mean canopy in cool spots |
|---|---|---|
| Berlin | 7.5°C | ≥20% |
| Paris | 9.8°C | ≥20% |
| Birmingham | 6.6°C | ≥20% |
| London | 5.2°C | ≥20% |
| Lyon | 5.2°C | ≥20% |
| Marseille | 4.8°C | ≥20% |
Cool spot criteria: mean canopy ≥20% within 60m, surface temperature below city 25th percentile, dwelling density ≥8 dw/ha.
Data sources
- Tree canopy: Google EIE (0.2m, 2020–2024) for 8 cities; Meta/WRI Global Canopy Height (1m, 2020) for all others. All vegetation counted (no height filter). Canopy assessed within 60m of each building. Hybrid fill applied where 0.2m coverage is incomplete.
- Surface temperature: Landsat 8/9 Collection 2 Level 2 (30m). Summer 2024 for most continental cities; May 2026 for UK; composites for Berlin, Sevilla, Hamburg.
- Buildings: IGN BD TOPO v3.x (France), Overture Maps (all other countries).
- Income: INSEE Filosofi 200m grid (France, 2019).
- Deprivation: IMD 2025 at LSOA level (UK). Zensus 2022 at 100m grid (Germany, rent as proxy).
- Threshold: 30% canopy cover within 60m, the minimum linked to measurable cooling (Ziter et al. 2019).
