There were no combined sewer overflows during storms last year and Minneapolis is gaining on Portland, Ore., in the quest to be the most bicycling city in the nation. Those are two of the highlights of a report on green efforts in Minneapolis, reports the Southwest Journal.

The city also passed an idling ordinance to battle greenhouse gas emissions from cars and trucks. Signs are going up soon in some city locations to remind drivers to not leave their vehicles idling for longer than three minutes.

Still, there are problems:

There has been a net loss of about 9,000 public trees over five years. The city’s goal is to have zero net loss.

And in battling so-called unhealthy air days, Minneapolis is far from its 2015 goal of 35 days or less. In 2008, there were 166 unhealthy air days.

“Thirty-five may not be a target we reach until we have all electric vehicles,” said Daniel Huff of Environmental Services.

More information is available in the city’s recently published Greenprint, the annual report on the city’s green efforts.
