It's easy to fall in love with nature when you're hitting the slopes around Seattle. Unfortunately, downhill skiing facilities aren't easy on the earth. It takes energy and water--often pumped from local streams--to make snow, and natural land must be cleared for paths and lifts. Not to mention the energy powering a resort, and the fuel we burn driving to the mountains.

But the ski industry is working to change things. In 2000, the National Ski Areas Association issued an environmental charter dubbed Sustainable Slopes. Since then, more than 180 ski areas have

pledged to invest in renewable energy sources,

eco-conscious waste management, and water and wildlife conservation.

Nearby Stevens Pass is one such green-minded resort. To curb transportation emissions, the Pass provides group transit for employees and an inexpensive shuttle for skiers. Visitors can also opt to add a two-dollar Green Tag to their lift ticket. The tags are carbon offsets equivalent to 100 kilowatt hours of wind power--roughly enough to offset driving to Stevens and back in a car getting 21 MPG.

The resort recycles and reuses literally tons of materials--down to vehicle hydraulic fluids and cooking oil. And the Pass offsets 100% of its greenhouse gas emissions with renewable energy credits.

Aside from choosing a resort that's making green progress, there are several things you can do personally to be an earth-friendlier skier or snowboarder. Carpool or take the shuttle instead of driving alone. At the end of the season, improve your car's energy-efficiency by removing your ski rack and snow tires. And check the used-equipment racks at REI and Second Ascent before buying new gear, since reusing is a great way to save resources.
