The Sierra Club is continuing their annual tradition of giving away free Earth Day stickers that arrive in 2-6 weeks. What better way to show your love of our rapidly dying planet than with a disposable paper product?!
After submitting your address, you'll be taken to a donation page. You don't have to fill this form out! Simply close the page once you get here and your sticker should arrive free of charge.
Update: Darn it, looks like this expired quickly. All I'm seeing is this 2020 sticker now.
Update 2: I think it's up and working again!
