How does green infrastructure improve air quality?

What is green infrastructure and how does it help with air quality?

Green infrastructure refers to a network of natural and semi-natural systems that provide environmental benefits. It helps improve air quality by filtering pollutants, reducing heat, and increasing vegetation, which absorbs carbon dioxide.

Can you give examples of green infrastructure?

Sure! Examples include green roofs, urban forests, rain gardens, and permeable pavements. These elements work together to enhance air quality and manage stormwater.

How do trees specifically improve air quality?

Trees improve air quality by absorbing carbon dioxide and releasing oxygen. They also trap dust, pollen, and other pollutants, which helps to clean the air.

Are there any studies that show the impact of green infrastructure on air quality?

Yes, numerous studies have shown that cities with more green infrastructure experience lower levels of air pollution and improved public health outcomes.

What can cities do to implement more green infrastructure?

Cities can implement policies that promote green spaces, invest in urban forestry, create incentives for green roofs, and engage communities in planning green infrastructure projects.
