In order to join the Immersion Carbonrally league, you must first register as an individual Rallyer and then create or join a Carbonrally team. To start, visit Carbonrally's School Teams -- Guide to Getting Started page and follow Step 1 to register as an individual Rallyer. Please note that Carbonrally account holders must be at least 13 years of age. If you are younger than 13, you must work in a buddy system with an adult (for example a parent, teacher, or after-school leader) to register for and use Carbonrally. You will be the one who accepts and completes challenges, but your adult buddy must be the one to register for Carbonrally using his or her e-mail address. Once you are signed up as a Rallyer, follow Step 2 to create or join a Carbonrally team. A Carbonrally team can be a class of students, an after-school science Club, or any other group of kids who want to make a difference. Before creating a new team, read all of the directions in Step 2 to make sure your group has not already created a team. Step 3 explains how to start taking Carbonrally challenges.

To take your Carbonrally experience to the next level, your group's team can join the Immersion league and compete against other Immersion teams across North America! It's easy to join our league. Just have your Carbonrally team leader (the person who created your team) use the form to the right to send your team's information to Immersion. We will then add your team to the Immersion Carbonrally league. To see other teams participating in our league, check out the Immersion league page. Stay tuned for updates on exciting prizes that will go to the leading Carbonrally teams in the league. In the meantime, get started reducing your carbon footprint!
