Philadelphia Tree Planting Part of Skyline Initiative -- Environmental Protection:
The planting of 30 trees in a North Philadelphia park and neighborhood is one of many projects planned to make Philadelphia, Pa., a cleaner and greener city through Sustainable Skylines, a U.S. Environmental Protection Agency program to help improve air quality and find solutions for other local environmental issues.
'Our Sustainable Skylines partnership with the city and other concerned organizations has a clear goal in mind – cleaner air in a greener city,' said EPA Acting Regional Administrator William C. Early. 'We commend Philadelphia as a leader in sustainability.' Philadelphia is the third city in the nation chosen to pilot the program.

Vanishing canopies affect air quality; Bangalore, India
Vanishing canopies affect air quality
Not only pollution levels but also pattern of planting trees has undergone a change
Vanishing canopies affect air quality

Gradual disappearance of tree canopies in Bangalore in the name of development has adversely affected the City’s air quality.
In a survey conducted at ten major road junctions in Bangalore (tree lanes and treeless lanes) by a City-based environment group, it was found that pollutants around canopy trees were comparatively less than along treeless stretch.
The study conducted by ATREE (Ashoka Trust for Research in Ecology and the Environment) in collaboration with Environmental Sciences Departments of St Joseph’s College and Mount Carmel College has found huge differences in air quality.
Dr Harini Nagendra, Urban Ecology Program Coordinator at ATREE, who supervised the study, said that it is not just pollution levels but also the planting patterns that have changed in the recent times. “Trees with huge canopies planted by our forefathers have been replaced with smaller trees by BBMP,” she said."

Do trees cause air pollution? Not a lot, but high reactivity of compounds is an issue; Joensuu, Finland; 4/27/09
Pining for terpenes separationsNOW.com - Chichester,England,UK
The results illustrate the difficulty in measuring plant emissions in situ but they still provide an indication of the levels of monoterpenes originating from pine forests as a whole and the needles in particular. In a study on the same site in 2003, the net ecosystem production was estimated to be 229 g carbon/m2/year, so, despite the uncertainty in the absolute monoterpene values, it is clear that they constitute a small proportion of the total volatile carbon. Their significance, however, lies in their high atmospheric reactivity and potential for aerosol formation.

N.J. Tree Foundation's Urban Airshed Reforestation Program in Camden has added 10 acres of UTC; Camden, NJ; 4/10/09
Trees bring shade, pride to Camden neighborhoods Cherry Hill Courier Post - Cherry Hill,NJ,USA
The N.J. Tree Foundation's Urban Airshed Reforestation Program in Camden wasn't expected to last this long when it first started in 2002. At that time, the state Department of Environmental Protection had given the Trenton-based nonprofit $1 million, half of the settlement a utility paid for an air pollution violation. The foundation planned to plant as many trees as that money could buy over three years.
By now, the foundation has planted more than 3,240 trees throughout the city with the help of some 6,100 volunteers and 104 partnerships.
That's six times more than the foundation has planted in a similar effort in Newark over the past three years.
In total, the group estimates they've added about 10 acres of canopy cover to the city with 81 species of trees.

Washington, DC; 12/23/08
Urban Tree Canopy Goals › Key Findings & Data Resources ...Washington, DC is now in the process of setting UTC goals in accordance with the District’s 2006 Comprehensive Plan and a 2003 directive from the Chesapeake Executive Council. The latest air quality plan (SIP) for the Washington, DC airshed includes establishing goals for tree canopy. The UTC framework may also be able to provide an accounting structure for using trees in this carbon trading scheme. By adopting Urban Tree Canopy goals, Washington, DC will join the likes of Baltimore, Annapolis, New York City, and Boston in using innovative technology to track and develop forward-thinking policies for our urban forest.
