6. Bag Your Lunch
Bringing your lunch to work is an easy and effective way to trim your carbon footprint, your spending, and your weekly trash output—and if you’ve been using your leftover plastic bags to carry those leftovers into your office, then it’s time for a greener solution. Pick up a used lunchbox at a thrift store or yard sale; choose a set that includes BPA-free containers; or replace your plastic or brown bags with smaller versions of the totes mentioned above. And if you’re a die-hard takeout fan, then at least keep a spare reusable bag in your briefcase so you can avoid taking a plastic version from your local sandwich shop.
