Sustainable travel is innovative, environment-friendly and cost effective. I choose Chicago to represent "sustainable travel" because the city is one of the pioneers in urban environmental initiatives. Hotels are being encouraged to be more energy-efficient, the city also pushed for more bikes lanes in the streets, and of course, the green roof on top of the city hall.
