In the United States, only about 9% of people commute to work via public transportation, cycling, or walking. Over 75% of people in the United States drive alone to their jobs.

Around the world, private car ownership has enabled polluting mobility trends to accelerate in urban areas, including inaccessible jobs and services, rising greenhouse gas (GHG), and increased road traffic accidents, resulting in injuries and death.

ITDP knows that fast, frequent, and well-funded public transit alongside other sustainable transport options like walking, and biking are the answer to combating damaging emissions. Public transit remains the only way to move large amounts of people quickly and sustainably. To reduce environmental harm, cities and systems must focus on methods to increase sustainable and clean transportation systems. The benefits of providing sustainable urban mobility are huge: each 5,000-mile decrease in average private vehicle driving saves more than one ton of carbon from entering our atmosphere every single year.
