Come support the Diesel Emissions Reduction Ordinance (DERO) at a public hearing in Boston on Tuesday! It’s our last push before the vote! DERO will require the best available retrofit technology and anti-idling enforcement on city-owned and city-contracted diesel vehicles, including major city construction projects. The time is now for Boston to catch up to other major cities and protect children and families from the harmful health effects of diesel pollution. Tuesday, December 18, 2012 Starts at 3:30 p.m., City Hall, 5th Floor Iannella Chamber, 1 City Hall Square, Boston, MA.
