Amazon’s annual Prime Days are taking place on June 16 and 17, yet while Amazon stands to profit off these deal days, they aren’t doing enough to combat their outsized ship pollution.

Companies like Amazon constantly benefit from marketing their climate commitments. But when it’s time to take significant action, these mega-polluters have very little to show for it. (We’re keeping score: check out where some of the world’s biggest brands ranked. Pssst: Amazon received a “D.”)

This Prime Day, send a letter to Amazon execs to tell them: Amazon is still a prime polluter!

Thank you for taking action.
