The holidays are an easy time to stay air-friendly, even during the hustle and bustle of shopping, welcoming friends and family and traveling to gatherings. If you’re shopping until you’re dropping, enlist the help of a friend to share the ride, carry packages and cross items off your list together. If you’re hosting a holiday party, check thrift shops for reusable serving dishes and glassware to give your table some eco-friendly sparkle. If your vehicle needs maintenance, get it checked before you hit the road. Ice scrapers make good stocking stuffers, and reduce the time spent idling when your windshield needs clearing.
