Over the past 30 years, science has demonstrated how trees provide many concrete benefits for people, society, and the environment.
Numerous scientific studies have shown that trees promote health and well‐being by reducing air pollution, encouraging physical activity, enhancing mental health, promoting social ties, and even strengthening the economy. As the world faces growing concerns about climate change—including rising temperatures and more frequent and more extreme weather events—it’s helpful to know that trees can contribute to reducing urban temperatures and provide the necessary infrastructure to support the management of stormwater.
To provide these benefits and more, trees need care—planting, mulching, pruning, and watering. It’s worth the time and money: experts have determined that every dollar invested in tree planting and management returns up to 500%. Trees also provide an estimated $18.3 billion in annual value of air pollution removal, reduced building energy use, carbon sequestration, and avoided pollutant emissions. Allocating resources for tree planting and maintenance is more than just a fiscally sound decision; it is an investment in the very well-being of people and the planet.
