The City of Pittsburgh, PA has announced an “urban forest master plan” to add more foliage to the 2.5 million trees already covering the city. Tree cover reduces energy bills, but is primarily seen as an issue of happiness and health by the city and the USDA. The City, the USDA, and Tree Pittsburgh funded a $275,000 plan that resulted from two years of data collection, analysis, consultations and benchmarking. The master plan reports the city has more than 2.5 million trees that sequester 13,900 tons of carbon dioxide a year, saved residents $3 million in energy bills last year and remove 519 tons of pollution at a savings of $3.6 million a year. Street trees alone diverted 41.8 million gallons of stormwater last year.
