I recently returned from Copenhagen, my first time to the Danish capital. Even a three day visit affirms why this city of more than 540,000 residents has received global recognition as a beacon of sustainable development. An incredible 36 percent of all commuting trips to work or school are made by bike along, in many cases, secure bike lanes that protect cyclists from cars and buses. Another 32 percent of city residents either walk or utilize the region’s highly-efficient public transportation network of buses and trains.
