Turfgrass is a living organism. Each plant takes in carbon dioxide and converts it into simple sugars to use as food through the process of photosynthesis. As a byproduct of photosynthesis, oxygen is released into the atmosphere.
A turfgrass area measuring 2,500 square feet produces enough oxygen for a family of four to breathe. An average sized healthy lawn can capture as much as 300 pounds of carbon per year and a golf course fairway can capture 1,500 pounds per year. One soccer field can offset the carbon produced by a car driving 3,000 miles.
Because of this, Dr. Thomas Watschke of Penn State University states in “The Environmental Benefits of Turfgrass and Their Impact on the Greenhouse Effect” that “the strategic use of turfgrass is the most sensible and economically feasible approach to countering the greenhouse effect in urban areas.”
In addition to reducing carbon dioxide, turfgrass traps an estimated 12 million tons of dust and dirt released annually into the atmosphere.
In 2013, an EPA Chesapeake Bay Program panel of experts concluded, based upon a review of extensive research, that a “dense vegetative cover of turfgrass” reduces pollution and runoff. More precisely, the average soccer field can absorb 50,000 gallons of water before runoff occurs. The fibrous root system stabilizes soil to reduce erosion and prevents the movement of sediment into creeks and rivers.
Additionally, studies have found the noise absorptive capacity of turfgrass is a significant part of how landscapes are effective in reducing noise pollution
