Page 23 Appendix II. Relative Tree Effects The urban forest in City of Pleasanton provides benefits that include carbon storage and sequestration, and air pollutant removal. To estimate the relative value of these benefits, tree benefits were compared to estimates of average municipal carbon emissions, average passenger automobile emissions, and average household emissions. See Appendix I for methodology. Carbon storage is equivalent to: •Amount of carbon emitted in City of Pleasanton in 11 days •Annual carbon (C) emissions from 7,730 automobiles •Annual C emissions from 3,170 single-family houses Carbon monoxide removal is equivalent to: •Annual carbon monoxide emissions from 1 automobiles •Annual carbon monoxide emissions from 4 single-family houses Nitrogen dioxide removal is equivalent to: •Annual nitrogen dioxide emissions from 91 automobiles •Annual nitrogen dioxide emissions from 41 single-family houses Sulfur dioxide removal is equivalent to: •Annual sulfur dioxide emissions from 0 automobiles •Annual sulfur dioxide emissions from 0 single-family houses Annual carbon sequestration is equivalent to: •Amount of carbon emitted in City of Pleasanton in 0.3 days •Annual C emissions from 200 automobiles •Annual C emissions from 100 single-family houses
