Robin Chase, who founded Zipcar, recently left her first brainchild to found GoLoco,  a new online ride-sharing network. GoLoco just shifted into high gear—pun obviously intended—on Earth Day, with the launch of its website, and it’s not actually about going crazy (as its name suggests) so much as it is about going low-CO2.

It’s part of Chase’s mission to get America pumped to cut our disproportionately large contribution to global warming. Did you know we make up only 5 percent  of the world’s population, but contribute more than 20 percent  of overall CO2 emissions? Did you know that 75 percent  of the car trips we take, we take alone?

Joining GoLoco is easy: Basically, you sign up for free, create a profile, and share away. And while GoLoco’s website is criminally user-friendly, Chase has gone to great lengths to make the network safe—members can withhold contact info and read others’ profiles before choosing to ride with them.

Speaking of profiles, you’ll have room in yours to upload your cutest headshot, as well as a list languages spoken, interests, and favorite music. That’s in case you want to team up with someone who shares your penchant for belting out Britney Spears tunes, in Portuguese, on the way to your next bungee jumping extravaganza, while saving the world from climate catastrophe!
