The Sustainable Portland Task Force released a report today on its two-year review of environmental policies and practices in Maine's largest city.

In Sustainable Portland, the task force recommends adopting a citywide net-zero goal for solid and hazardous waste, promoting green businesses that specialize in environmental products and implementing a climate action plan.

Established in 2006, the task force conducted a comprehensive review of current practices and strategies that could be used to make Portland a more sustainable city.

A sustainable community is one that preserves and develops ecological, economic and other systems to ensure its longevity.

The report cites a number of existing practices in Portland, including the construction of environmentally certified schools, upgrades to the sewer system to reduce storm-water overflow, and the Portland Buy Local Campaign.

"This report is a great road map for decision makers, businesses, and residents on how to work together to build a more sustainable city," City Councilor Jill Duson said in a prepared statement.
