European cities lead the way on greenhouse gas reduction

Several Missouri cities, including St. Louis, Kansas City, and Columbia, have signed on to an effort to reduce greenhouse gas production.

Transportation is a major contributor to greenhouse gases.

According to a KCStar article:

Copenhagen is often cited as a climate pioneer among European cities. It cut CO2 emissions by 187,600 tons annually in the late '90s by switching from coal to natural gas and biofuels at its energy plants. Its goal is to reduce emissions by 35 percent by 2010, compared to 1990 levels, even more ambitious than Denmark's national target of 21 percent cuts under the Kyoto accord.

In 1995, the city became one of the first European capitals to introduce a public bicycle service that lets people pick up and return bikes at dozens of stations citywide for a small fee. Similar initiatives have since taken root in Paris and several other European cities.

Next, Copenhagen plans to spend about $38 million on various initiatives to get more residents to use bicycles instead of cars.
