We have taken big steps to reduce our emissions from power plants—so much so that transportation is now the #1 source of California’s carbon footprint.

• The best way to reduce our emissions is build homes in cities. “Infill construction” adds new housing near jobs, buses, and trains. The connection between housing, economic vitality, and transit creates a win-win for the environment in two ways.

First, it reduces the number of people who have to drive to work. If you live closer to your job, you can choose to commute by bike, bus, train, or walking. Even if you don’t do this every day, this will lower your carbon footprint. With millions of Californians involved, this will create a big carbon reduction.

Second, even if you keep driving to work, you will drive a shorter distance. You’ll save money on gas and maintenance as you save the environment by emitting less CO2.
