Les scores se concentrent dans le haut de l’échelle ; la position au sein du catalogue est donc souvent plus parlante que le chiffre seul.
Carbon — sequestration / storage, evidenced1/3
Green-roof energy savings (~20% electricity, per EEWH projections) plausibly cut operational emissions, but no cited study measures actual carbon sequestration or avoided emissions in tonnes.
Biodiversity — conservation / improvement, evidenced1/3
Rooftop greening is often claimed to support habitat, but the cited hydrological and thermal studies measure runoff and temperature only, not species or habitat outcomes.
Water & soil — retention, infiltration, erosion control2/3
Peer-reviewed hydrological modelling directly measures seasonal runoff reduction (14-59%) from converted green roofs, though only about 1% of the city's roof area is structurally convertible and performance drops sharply in heavy rain.
Fire resilience — risk reduction, evidenced0/3
No fire-risk evidence is reported for this greening policy.
Governance, certification & transferability3/3
Codified in a binding municipal ordinance (40-70% Green Plot Ratio) and nested in a national EEWH certification system tracking 12,585 certifications, giving strong regulatory transferability across Taiwan.
