Have you been on the fence with adopting a vegan lifestyle? JAY-Z and Beyoncé are offering fans a little extra incentive: free tickets to any of their shows, anywhere, for life. The contest, part of The Greenprint Project, was announced Wednesday (January 30) via Beyoncé’s Instagram.

Going vegan is a choice that may be an intuitive next step for vegetarians, but a huge leap for anyone who currently eats meat. For this reason, the contest is focusing on inspiring individuals to adopt manageable commitments for eligibility, such as two plant-based meals a day or “Meatless Mondays.”

The contest and corresponding website — which helps illustrate the positive impact that small commitments to plant-based meals can have on the planet — is the second phase of the overall The Greenprint Project. 

Conceived by Marco Borges, who founded and co-owns 22 DAYS NUTRITION with JAY-Z and Beyoncé, the project started with a book released on December 31, The Greenprint: Plant-Based Diet, Best Body, Better World (which includes an introduction by the power couple), and will culminate with a documentary film later this fall.
