Historically, environmental consciousness has weighed significantly in the city's planning and development efforts. Portland was one of the first cities in the United States to promote and integrate alternative forms of transportation, such as the MAX Light Rail and extensive bike paths. The Urban Greenspaces Institute, housed in Portland State University Geography Department's Center for Mapping Research, promotes better integration of the built and natural environments. The institute works on urban park, trail, and natural areas planning issues, both at the local and regional levels. In October 2009, the Portland City Council unanimously adopted a climate action plan that will cut the city's greenhouse gas emissions to 80% below 1990 levels by 2050. The city's longstanding efforts were recognized in a 2010 Reuters report, which named Portland the second-most environmentally conscious or "green" city in the world after Reykjavík, Iceland.
