So says the New York League of Conservation Voters, which has just released its review of the New York City Council’s 2012-13 legislative performance on environmental and sustainability issues.

In their Environmental Scorecard, the League argues that:

“From sustainable food and clean energy, to green buildings and mass transit, she [Quinn] played a pivotal role in the transformation of New York City into the sustainability leader it is today. The sheer volume of environmental legislation adopted by the Council…reflect the high priority Quinn placed on sustainability.”

And the League says that Quinn not only worked with the Bloomberg administration “to advance its environmental agenda” but the Council “frequently initiated and approved legislation that was not a priority on the other side of City Hall.”

The scorecard highlights areas—Solid Waste and Recycling, Air Quality, Climate Change and Resiliency, Transportation, Food Access, and Green Buildings—where the NYLCV says the Council made major advances under Quinn’s leadership.

The League also looks at 17 pieces of key legislation passed last year, and ranks the environmental performance of each 2012-13 Council Member, including new speaker Melissa Mark-Viverito.
