Evidence of impact / measured results1/3
Cooling of about 2°C is reported by city officials and press and site-level before/after data exist, but no controlled peer-reviewed evaluation was found and UCL calls for robust evaluation.
Transferability / demonstrated replication2/3
The approach uses standard planting and has been widely presented as a model for hot cities, but its effect size is not independently established.
Scalability2/3
It reached 30 corridors, about 2.5 million plants and 880,000 trees by 2021 for USD 16.3 million, showing scale within one city.
Sustainability / continuity2/3
Upkeep is a stated condition for lasting benefits, and long-term maintenance funding is not clearly documented in the sources.
Innovation2/3
It treats road and waterway edges as a connected cooling network, which earned a 2019 Ashden cooling award.
Inclusiveness / equity2/3
A training scheme employed 75 gardeners from vulnerable or displaced groups, but the distribution of cooling across poorer neighbourhoods is not documented.
Multi-stakeholder collaboration2/3
It combined the city's environment secretariat with gardener training and award-level recognition, though the roles of other partners are less documented.
