Abstract Summary
Like many urban areas globally, Amsterdam faces the increasing challenge of urban air pollution. This empirical study, conducted within the AMS Urban Comfort Lab, investigates the direct impact of green walls and vertical greenery on urban air quality. Distinguishing from previous research relying on simulations and models, our early study results reveal a significant 18% reduction in pollutant levels associated with integrating green walls. Using machine learning, we identify green walls locations in Amsterdam and quantify their potential in delivering cleaner air. As Amsterdam and cities worldwide grapple with declining air quality, this research offers a glimpse of a future where urban environments prioritize environmental sustainability and public health.
