SCAN webinar poster

Street canyons are the most polluted city environments due to high traffic volumes and limited ventilation. In the Covid-19 era, urban green infrastructure (GI) is more important than ever.

GI offers many benefits, including air pollution abatement. However, relationships between GI, air quality and cooling of the street environment are complex and optimal GI design remains unclear, with potential for negative repercussions. To support decision-makers and address this global need, we will develop a new framework for street-scale greening that is generic, inclusive of pollution-cooling trade-offs, evidence-based, and practicable.

We will use experimental and modelling approaches, undertake trial demonstrations, and integrate results to create a collaborative platform. We will engage stakeholders, foster staff-student exchange and develop scope to leverage future funding via research proposals.

This webinar is an integral aspect of the SCAN project, providing an international platform for researchers to facilitate improved health and wellbeing in cities through knowledge exchange. It is an opportunity to reflect on project activities and share findings and perspectives regarding the use of green infrastructure for urban heat and air pollution mitigation, particularly in street canyon environments.
