The 17-year-old powerhouse rising pop star Billie Eilish is offering fans free tickets if they’ll help take action against climate change.

In under one year since the release of her debut record, When We All Fall Asleep, Where Do We Go?, Eilish has been taking steps to be a positive driving force in the ever-changing world. Other artists have stepped up to the plate and offered initiatives, but it’s still not enough to truly help the large issue at hand.

In September, Eilish teamed up with actor Woody Harrelson to release a video clip to bring more awareness to the cause, citing that “our Earth is warming up and our oceans are rising” and “extreme weather is wrecking millions of lives.” Now, she released another video, where she explains how she is working with Global Citizen to help her fans snag free tickets to shows while also benefitting a good cause.

“I do not want you guys to have to buy tickets from scalpers, and I know you all still really want to come to the shows,” she said in the video clip. “So I teamed up with a great organization called Global Citizen to help come up with a way to earn tickets to the Where Do We Go? Tour.”

Fans can go to globalcitizen.org/billie and sign up to win tickets. From there, they can sign up for an account with Global Citizen and take action for a more sustainable world by picking issues that are important to them. Users can choose between: Girls & Women, Health, Education, Finance & Innovation, Food & Hunger, Water & Sanitation, Environment, or Citizenship. Then, they’ll be able to enter for a chance to win a pair of tickets to upcoming shows on Eilish’s second round of tour dates to support her debut album, which will run through next year.
