It's a paradox: although backpackers, particularly those who are hardcore, are committed to "leaving no trace," and surely appreciate our natural environment, we still consume fossil fuels getting to our favorite trailheads, and damage, however minimally, the environments in which we hike. Most of us, also, are still totally into gear: backpacks, tents, and the like, which can consume resources, even petroleum, and can produce pollution through their production.

Although backpacking can be one of the most eco-friendly vacations one can take (let's face it, you're walking everywhere), can backpackers lessen their eco-footprint? Although environmentalism has always been on the radar of those who enjoy the outdoors, there are more and more options that allow backpackers and hikers to make greener choices to preserve the nature that they love getting away to.

First and foremost, getting to and from the trailhead can be a major source of carbon impact. Consider taking the train or bus instead of driving or flying. The Appalachian Trail has multiple sections that are serviced by train or bus, as does the Pacific Crest Trail, and the John Muir Trail. And if you take the train you don't have to worry about your car getting broken into while you are on the trail. If worse comes to worst, you can (gulp) offset your travel.

Second, remember to obey leave no trace principles. Sometimes, after a long day of elevation gains, unexpected rain, and blisters, you might not feel like packing out the leavings of washing dishes, or the thought of a roaring campfire trumps the knowledge that you probably shouldn't make one, or you feel like wandering off the beaten trail. It may seem like your actions don't really make a difference on your favorite trail, but according to Leave No Trace, backpackers have a significant impact on the wildlife, water sources, and vegetation of their favorite habitats.

Finally, keep an eye out for greener options when buying gear. Outside magazine recently released it's green issue and, in its yearly gear guide, included an entire section devoted to eco-friendly outdoor gear. Backpacker considers green gear when reviewing products for their magazine, and awards annual "Green Awards" for sustainable gear. Teko socks kept my feet dry and blister-free through a 21 mile overnight on the Colorado Trail, have eco-friendly packaging, and are made of recycled polyester. Patagonia has established itself as an industry leader in environmentally-friendly business practices, and much of their clothing is made of recycled materials and can be returned to the company (via a retailer or the company's website) for recycling. Chaco sandals were ubiquitous on and off the trail, and are produced using recycled rubber and water-based glues. Lafuma has a new hemp pack and a more sustainable sleeping bag, and Nau recently released its highly-anticipated line of on and off-trail clothing.
