Project Description

What could keep you from driving to work alone all the time? What would you say if you were paid to give up your free parking space at the office?

Many employees in California have been offered this deal since the 1990s, and many of them have subsequently benefited from this policy — called parking cash out.

One relatively simple tax policy change could have a huge impact on the number of commuters who drive alone, and therefore on greenhouse gas emissions and congestion.
