Trees enrich and improve our environment and
dramatically increase the overall quality of life in New York City. The benefits
provided by trees are numerous and diverse, making it important to quantify
their value to our city and its residents.
The primary benefits provided by New York City’s urban forest come in
three key areas:
1. Environmental
Benefits
- Slowing Global Climate
Change - Urban trees help offset climate change by capturing
atmospheric carbon dioxide
in their tissue, reducing energy used by buildings, and reducing carbon
dioxide emissions from fossil-fuel based power plants. Our City’s trees store
about 1.35 million tons of carbon valued at $24.9 million. In addition, our
trees remove over 42,000 tons of carbon each
year.
- Water Quality
Protection - Urban trees capture rainfall on their leaves and branches and
take up water, acting as natural stormwater capture and retention devices.
Street trees intercept 890.6 million gallons of stormwater annually, or 1,525
gallons per tree on average. The total value of this benefit to New York City
is over $35 million each year.
- Improved Air Quality - Trees remove
dust and other pollutants from the air. In fact, one tree can remove 26 pounds
of carbon dioxide from the atmosphere annually, the equivalent of 11,000 miles
of car emissions. Our trees remove about 2,200 tons of air pollution per year,
valued at $10 million annually.
- Lower Summer Air Temperature -
According to the U.S. Environmental Protection Agency, urban forests reduce
urban temperatures significantly by shading buildings and concrete and
returning humidity to the air through evaporative
cooling.
- Natural Resource Conservation - By
using trees to modify temperatures, the amount of fossil fuels used for
cooling and heating by homeowners and businesses is reduced. Our City’s street
trees provide $27 million a year in energy
savings.
- Wildlife Habitat – New York City’s urban
forest provides habitat - including food and shelter for many species of
birds, insects, and other wildlife, as well as environmental education
resources for New Yorkers of all ages.
2. Economic
Benefits
- High Return of Investment – Over the
years the City has invested millions in its urban forest. Trees provide $5.60
in benefits for every dollar spent on tree planting and
care.
- Increased Property Values - A
significant link exists between the value of a property and its proximity to
parks, greenbelts, and other green spaces. Smart Money magazine indicated that consumers value a landscaped home up to 11.3
percent higher than its base price. Street trees provide $52 million each year
in increased property values.
- Community and
Business District Appeal - The greening of business districts increases
community pride and positive perception of an area, drawing customers to the
businesses. See
Case study from Washington D.C.
3. Health and
Lifestyle Benefits
Improved Health
- There is growing evidence that trees help reduce air pollutants that can
trigger asthma and other respiratory illnesses. Green spaces also encourage
physical activity - a healthy habit for any New
Yorker.
