Throughout its lifecycle, a pair of jeans consumes as much energy as powering a personal computer for 556 hours. You can reduce the full lifecycle climate change impact of your jeans by up to 50% by line drying and washing them in cold water. Levi’s Care to Air Contest is a new campaign that is sharing these ideas in sustainability. For a chance at winning the $4,500 grand prize, just submit your designs for easier, more efficient air drying technologies. You can also view the current entries and vote on your favorites.
