The research paper examines how urban forests influence air quality and public health. It highlights that trees improve air quality by directly removing gaseous pollutants and particulate matter, and indirectly by reducing urban heat island effects and building energy demand. However, it notes that trees can also emit volatile organic compounds (VOCs) and pollen, and may trap pollutants near emission sources like roadways if not designed correctly. The paper concludes that while the overall effect is positive, local forest design is critical to maximize health benefits.

The toolkit offers sample messaging and talking points to highlight how urban trees mitigate extreme heat, improve air quality, and enhance public health. It specifically promotes the #FundingUrbanForestry campaign and the use of Inflation Reduction Act funds to expand urban canopies and create green jobs in underserved communities.

The document provides a series of social media templates for Urban Forestry Grant awardees to promote the environmental, health, and economic benefits of urban tree planting. It highlights the role of urban forestry in mitigating extreme heat, improving air quality, and creating livable wage jobs, specifically targeting communities of color and low-income areas to promote tree equity.
