Why Trees?

Trees have a powerful impact on air quality, climate change, energy conservation, water quality, economy, comfort, habitat, and public health.

Air Quality

Trees help us clean the air.

Tree leaves absorb dirty air and remove pollutants. Particulates pollution like dust is deposited on the leaves. Plus, trees absorb carbon dioxide and produce oxygen for us to breathe. Trees cool the air by releasing moisture into the air through a process called transpiration.

  • 100 trees remove five tons of CO2 per year
  • 100 trees remove about 1000 lbs of pollutants per year, including:
    • 400 lbs of ozone
    • 300 lbs of particulates

Sacramento has some of the worst air quality in the United States. If we can plant 5 million trees it will help us meet federal and state air quality requirements, which will prevent the loss of millions of dollars in funding.
