Whether along neighborhood streets, backyards or packed into urban forests, trees are powerful yet affordable tools cities like San Jose can deploy to fight climate change and protect residents.

10 Benefits of Planting Trees for the Environment

Let’s explore the top 10 science-backed ways planting more urban trees helps the environment, wildlife and San Jose community:

  1. Clean the Air As the world’s lungs, trees provide the invaluable service of continuously filtering harmful pollutants out of the air. Through their leaves, trees absorb widespread pollutants like ozone, nitrogen oxides, ammonia and sulfur dioxides that trigger asthma and breathing issues. Large tree canopies also catch airborne particulates like dust, ash, pollen and smoke that make air unhealthy to breathe. Here in San Jose, increasing tree cover across neighborhoods enhances public health by cleansing our air of dangerous particles emitted by high vehicle traffic and industrial zones.
  2. Reduce Greenhouse Gases Climate change poses massive economic and public health threats to San Jose in the coming decades. Trees offer a simple, natural way to remove heat-trapping carbon dioxide from the atmosphere to reduce the Greenhouse Gas emissions pushing climate change. During photosynthesis, trees absorb CO2 while releasing the oxygen we all breathe. Their branches, leaves and roots then store excess carbon absorbed. Expanding San Jose’s urban canopy provides needed help mitigating our city’s carbon footprint to fight climate impacts.
  3. Reduce Soil Erosion Have you ever seen gullies carved into the dirt after heavy San Jose rains? This damage comes from destructive soil erosion washing away fertile land. Tree roots anchor and hold soil firmly to prevent heavy flows of rainwater from stripping away topsoil crucial for growing vegetation. Trees also break the impact of raindrops on bar soil, further reducing erosion. With climate change expected to increase extreme rain events in San Jose, erosion control from trees preserves our local soil integrity.
  4. Protect the Ozone Layer Up in Earth’s stratosphere, the ozone layer acts as a radiation shield that protects us from ultraviolet rays of sunlight linked to skin cancer and other health issues. Yet manmade chemicals have damaged this vital atmospheric sunblock for decades, causing dangerous ozone depletion. Amazingly, trees motivate ozone layer recovery!Trees release special chemicals that reduce the atmospheric reactions eroding ozone, allowing the protective layer to heal over time. More ozone security means less UV exposure for San Jose residents.
  5. Rainfall washing fertilizers, motor oils and industrial runoff into watersheds contributes to unsafe waterways. By acting as a barrier, tree canopies and roots absorb much of this polluted urban runoff before it reaches groundwater, rivers, lakes and oceans. Tree canopy cover has directly lowered contaminated stormwater runoff in Portland and other cities by up to 60%! Using more trees in San Jose to filter out harmful nutrients, metals, bacteria and chemicals leads to cleaner water resources.
  6. Conserve Energy As the mercury rises every summer, so does energy consumption powering San Jose’s air conditioners. Strategically planted shade trees cool buildings naturally to reduce this electricity demand across the city. Leaves filter out intense sunlight while tree canopies channel cooling breezes to keep structures more comfortable. Blocking the sun’s heat also decreases temperatures of sidewalks, streets and parking lots during hot days to alleviate urban heat islands. Through this natural climate control, urban trees shrink costly energy bills!
  7. Save Water Thick tree canopies trap rainwater and increase infiltration into the soil. This groundwater recharge alongside moisture conservation from shade coverage allows urban forests to boost drought-resilient water savings. Cities benefit both from reduced stormwater runoff and irrigation water needs for lawns and gardens sheltered under trees. As San Jose faces hotter, drier conditions from climate change in the upcoming decades, maximizing urban canopy coverage leverages trees’ water savings superpowers when we need it most!
  8. Provide Habitat In addition to human inhabitants, trees host a diversity of wild neighbors by supplying vital shelter and food resources. Their nooks offer safe nesting sites and protection for species like owls, squirrels and songbirds, while ample seeds, nuts and insects feed various birds and mammals. Urban green spaces with mature, native trees create thriving ‘sky islands’ to sustain wildlife otherwise displaced by surrounding development. Boosting San Jose’s canopy coverage through tree planting drives up essential habitat for local creatures.
  9. Protect the Ecosystem From cooling streams to sustaining wildlife, ecosystems everywhere benefit from the presence of healthy trees. Their shade maintains cool water temperatures needed by fish and amphibians to survive, while plentiful flowers, nectar and seeds support diverse pollinators and herbivores. Fallen leaves make excellent fertilizer to nourish soil food webs and boost new plant growth. Tree roots even prevent landslides and floods by holding soils together. Wherever found, trees create the architecture sustaining ecosystems able to better adapt to climate change.
  10. Provide Economic Opportunities While their environmental superpowers take the spotlight, trees also grow economic opportunities from jobs production to higher property values. Tree planting initiatives create local green jobs for nursery workers, arborists, foresters and horticulturalists. Real estate agents also know homes shaded by lush canopies often sell for 3-15% more—great news for San Jose sellers! When the many economic perks of trees add up, investing in our urban canopy delivers a win-win for both community income and the environment.


As ecosystems in overdrive from pollution, habitat loss and climate impacts, trees provide relief through cost-effective yet powerful environmental benefits. From overhead forest canopies to saplings along neighborhood walkways, protecting and expanding San Jose’s urban trees is vital to create a healthy, resilient city. Whether reducing extreme heat and flood risk or conserving water and energy, trees are invaluable tools for fighting climate change where we live.

We don’t need advanced technology to make positive environmental change—just commitment to planting more high quality, biodiverse trees. Their intricate root systems will stabilize soils, their lush leaves filter out dangerous particles, and their sturdy trunks provide shelter from harsh climates amplified by climate change. San Jose depends on trees to build sustainability today and ensure our communities thrive for generations to come.

Next time you walk past an empty tree bed on your street, envision the pollution-purifying, storm-soothing, heat-rescuing environmental guardian waiting to be planted there. Then grab your shovel alongside family, friends and neighbors to start transforming your neighborhood for the benefit of all. Our urban forests are mighty weapons against climate change that we must wisely utilize. And the work starts with you, me, and the trees in our own backyards.
