What does this research mean for the field?

Urban green infrastructure, particularly well-maintained urban greenspaces, can simultaneously mitigate the urban heat island effect and improve air quality through interacting thermal and mitigative traits, though a combination of different UGI types is necessary to maximize these dual benefits.

Implication

Comprehensive review demonstrates dual thermal and air quality mitigation from urban green infrastructure in metropolitan areas, suggesting integrated planting designs maximize urban cooling.

Key Points

To review and synthesize evidence on the dual capacity of urban green infrastructure to simultaneously mitigate the urban heat island effect and improve air quality.
Synthesized mechanistic and qualitative literature on thermal and air pollution mitigation pathways across ground plantings, green roofs, and vertical greening systems.
Evaluated trade-offs and confounding variables including biogenic volatile organic compound emissions, species selection, climate zones, and canopy-induced night-time warming.
Well-maintained urban greenspaces provide broad combined mitigation of heat and air pollutants, whereas engineered systems like green roofs provide localized effects.
Vegetation cools air through shading and evapotranspiration while removing pollutants via foliar sequestration, thermophoresis, and secondary aerosol inhibition.
UGI efficacy is constrained by species-specific biogenic volatile organic compound emissions, climate variability, and nocturnal heat trapping beneath dense tree canopies.
