FINAL REMINDER - ONLY 3 DAYS LEFT TO PARTICIPATE! The White House is launching the second GreenGov Challenge! If you're a federal employee, share your idea on how the federal government can lead by example in eight different categories -- from climate change mitigation and resilience, to water conservation, to waste reduction. Submissions are open until 5 December 2014. After the submission period closes, GreenGov will release the approved submissions and all federal employees will be able to vote for their favorite ideas.
