Parking spaces are important to the daily travel of many individuals and have become a seemingly necessary part of everyday life. The construction of these spaces is directly responsive to an area's surrounding population. As an economy grows, the number of business patrons and urban residents increases as does the size of the commuting workforce, many of whom will need a place to park their vehicles. For some cities, it is easy to assume that providing parking is inexpensive or good for business. Free parking comes with costs that extend beyond a simple monetary accounting. There are large environmental costs that also go along with such a transportation policy. In the context of sustainability, the environment, and climate change, the environmental impacts of parking infrastructure have not been addressed until recently. The major reasons for this are that the environmental implications of abundant parking infrastructure have been understudied and at the same time overshadowed by other sustainability issues such as alternative energy, energy efficient construction, and alternative transportation. A review of current literature was conducted to better understand how an abundance of free parking can negatively impact the environment and a community, as well as how city planners might address this problem. As a result, this review seeks to raise awareness of the environmental impacts associated with an abundance of free parking, and present possible options, tools, and strategies to resolve these issues.
