6.A. - Page 25 of 251 <br />Introduction <br />Carbon Sequestration <br />Many actions that address climate vulnerability and risk also reverse emissions of GHGs into the atmosphere. <br />Shade trees absorb, or sequester, carbon dioxide from the atmosphere. Studies show that a young tree sapling <br />can sequester anywhere from 1.0 to 1.3 pounds of carbon each year, while a 50 -year-old tree can sequester over <br />100 pounds annually.14 Restoration of wetlands can both sequester carbon and be implemented in a way that may <br />protect shoreline communities and habitats from sea -level rise and storm surge. Healthy soils on farmland also <br />play an important role in absorbing carbon. <br />Actions to sequester carbon in trees, soils, and vegetation can minimize stormwater runoff and increase <br />biodiversity of plants and animals. Biodiversity is critical to the health of City parks and other open spaces. Natural <br />area conservation protects natural resources and environmental features that sequester carbon, reduce <br />stormwater runoff, promote infiltration, prevent soil erosion, and increase ecosystem biodiversity. <br />Municipalities with urban forests should consider end -of -life practices for trees to ensure the carbon embedded in <br />the tree is maintained after a tree is cut down. As outlined in Chapter 6: Strategies & Actions, in the Carbon <br />Sequestration section, some options include: using the tree for lumber for local construction, upcycling a dead <br />tree into park benches or furniture, or converting it into biochar. <br />City of Redwood City Climate Action Plan 14 <br />330 <br />
