Madison Named "Greenest" City in America

Nerdwallet recently named Madison the "greenest" city in America. "Madison earns the distinction of being the greenest city in the U.S., partly due to the fact that the city is literally “green” — its 12.7 parks per 10,000 residents is the highest mark of all cities in the country. The Madison area is home to over 15,000 acres of lakes and more than 200 miles of biking and hiking trails. In fact, the city boasts more bikes than cars, which no doubt contributes to the area’s great air quality."

The greenest cities were determined by NerdWallet based upon:

  1. Environmental quality: The median Air Quality Index for each city — the lower the AQI, the better — as well as the number of parks per 10,000 residents.

  2. Green transportation: Percentage of the population that walks, bikes, carpools, takes public transportation or works from home in each city. In addition to excess fuel consumed per commuter, which is wasted fuel due to congested conditions in the city.

The 95 largest cities in the U.S. were considered in the analysis. The top five greenest cities were Madison, WI; Anchorage, AK; Corpus Christi, TX; Rochester, NY; and Greensboro, NC respectively.


Go Green. Ride Metro.

Metro Hybrid Buses

Metro's Green Efforts

Metro is the first system in Wisconsin to add hybrid electric powered buses to its fleet. Fourteen additional hybrids have been added so that now 10% of Metro's buses are now hybrids.

What is a hybrid bus?

Hybrid bus motors act like generators. Through a process called "regenerative braking", energy created while a bus slows or stops is converted to stored electric energy.

Forty percent of the energy to accelerate the bus is actually
energy saved during the braking process.

Metro currently estimates that hybrid buses get 20 - 30%
better gas mileage than regular diesel buses and reduce exhaust emissions by 90%.


Metro's entire fleet operates on ultra-low sulfur diesel fuel that reduces hydrocarbon emissions by 75%.


Metro Transit uses 37% Green Power, which is a combination of windpower and other environmentally-friendly energy-producing sources, to power its administration and maintenance facility.
