The city of Copenhagen has done something revolutionary: For the past 40 years, the Danish capital has reduced its parking supply. Cutting the total number of parking spaces by a small percentage each year. Compare this to the stark contrast to global patterns of cities adding more and more parking to accommodate private cars.

Cities across the planet are recognizing that managing parking is an effective means of addressing concerns about energy , traffic congestion and course climate change. According to research from the Paris-based firm Sareco, people choose their mode of transportation for urban trips based on the parking conditions at their origin and destination.
