Country star Keith Urban is going green on his upcoming tour by running his tour buses on biodiesel fuel and offering fans the chance to buy t-shirts made from recycled plastic bottles. He has teamed up with environmental t-shirt firm Chaser Merchandise to make sure the gear he’s offering fans is as green as possible.

He says, “While I am far from the greenest guy on the block, I do look for situations where I can make even a small difference. And so the idea that our concert tees could retain the same look and feel, but be partly made from recycled materials appealed greatly to me.”
