Clear the Air by . . . Driving?

At least by driving smarter.

Hear us out: You’ve heard that a big chunk– roughly 50 percent — of Salt Lake City’s winter air pollution comes from motor vehicles.

That’s why SLCgreen promotes cleaner transportation and getting out of our cars as much as possible, particularly during February and the Clear the Air Challenge.

But, we know that taking public transit, biking, or purchasing an electric vehicle is not practical for everyone – yet! However, there are some important ways to reduce pollution even when you do drive.

We all want to take better care of our health and live in a healthy world and by planning ahead we can help our city have fewer red air days! Here’s how:

Unfortunately, our weather patterns and geography mean we have to work extra hard to reduce what goes into the air.

One of the simplest things you can do is to leave the car at home.

Did you know that the majority of pollution comes when you simply turn your car on?

It’s the phenomenon of “Cold Starts.”

It means that 60-90% of your commute’s emissions come in the first three minutes. Pretty incredible, huh?

You can learn more about cold starts from UCAIR’s great blog post and video below.

So what can you do? Well, aim to keep your car parked as frequently as possibleeven if it’s just for a day, or a single trip you’re skipping
