Some residents in Greensboro are eagerly awaiting the details of a proposed tree ordinance. A city council subcommittee finished the draft for the ordinance this week, but it has not yet been made public.

The new measure comes in response to a dispute between property owners and Duke Energy over the company’s practice of cutting trees.  Nancy Vaughan is an at-large City Council member who helped write the ordinance draft.

"We were able to protect private property as well as public right of way," says  Vaughan.

A new study from researchers at the University of North Carolina at Chapel Hill has revealed exactly how trees play a role in smog production. The question has been a source of scientific uncertainty for years, and the findings are a milestone in air pollution research, with potentially significant implications for public health.

The American Lung Association’s annual State of the Air report is out, and it slots Greensboro as the 42nd most polluted metro area in the county.  The city received an F-rating.

Laura-Kate Bender, who worked on the report, says the news wasn’t all bad.

"Despite getting an ‘F,' the area actually got its lowest overall number of smog days," she says. "So even though it received a failing grade, it’s a significant improvement over last year."

The natural gas extraction process called hydraulic fracturing, also known as fracking, has been a source of debate and contention in the state for quite some time now. It involves drilling horizontally through thousands of feet of shale and blasting the shale with water, sand and chemicals to release natural gas. Several states allow the process, some are in the process of figuring out how to regulate it, and some, like New York, have placed a moratorium on the process due to environmental concerns.
