Walk Score is an online tool that helps users determine neighborhood walkability — the extent to which walking is a convenient, safe and pleasant way to get around.
The tool calculates the amenities available within walking distance from a given address or neighborhood and uses that information to calculate a walkability score between 0 and 100. Using this tool encourages rethinking the value of neighborhoods in terms of what services and businesses are located within a walkable distance. Neighborhoods that have a high walkability do not require as much driving as neighborhoods with low walkability.
Walk Score is a tool that is useful for transportation planners, developers, business owners and people interested in moving to a walkable area or advocating for pedestrian improvements to their existing community.
Walkable neighborhoods require less driving, which cuts greenhouse gas and other emissions. Residents of highly walkable communities get the additional benefits of increased exercise, reduced need to use fuel and more time near their home. Walkable neighborhoods also facilitate interactions with neighbors, which creates social capital and safer communities.
Greenhouse gases are a part of the Earth's atmosphere and are both naturally occurring and the result of human chemical processes. The most common greenhouse gases are carbon dioxide, water vapor, methane, nitrous oxide, ozone, and chlorofluourocarbons. These gases trap heat and thus contribute to the warming of the planet.
