Hillary Clinton, eco-warrior? Not quite, but the New York senator does have a long, diverse environmental record that's nearly bulletproof. "Our values demand that we be good stewards of the planet for our children and our children's children," Clinton said in May 2006. "We are failing that simple moral test if we stand by while the earth warms."

Battle Cry: "The Bush administration has reversed decades of progress on the environment," Clinton tells Outside. "As president, I would restore these protections. I would tell my EPA administrator to protect the environment instead of polluters."

Green Chops: Since 2000, Clinton has spearheaded or co-signed nearly 400 environment-related bills, promoting issues from brownfield redevelopment to national-forest protection. "I've taken many actions specific to New York, like pushing for the Hudson River cleanup by GE and tackling the toxic legacy of 9/11," she says. "As First Lady, I focused on the environment's effects on children's health."

Power Points: "The country that split the atom and put a man on the moon can take the oil out of our tanks," she says on a campaign Web site podcast. Clinton proposes yanking oil-industry subsidies and depositing the savings (she estimates $50 billion over the next ten years) into a Strategic Energy Fund used to develop solar, wind, clean-coal, and nuclear power. Her Green Building Fund would bankroll energy-efficiency upgrades in schools and libraries to the tune of a billion bucks a year.

Outside Moment: After graduating from Wellesley College in 1969, she "spent a summer in Alaska, washing dishes at a lodge in Mount McKinley [now Denali] National Park and sliming salmon in Valdez." Clinton returned to Alaska in 2005 to size up climate impacts on the state.

Eco-Hero: Al Gore. "I may not agree with everything he proposes, but he has never given up on his climate mission."

Hmmm: "It's time to stop federal funding of oil industries, once and for all!" she's said at several campaign rallies. Yet Clinton has accepted more campaign contributions from the oil and gas industries—a total of $151,950 as of October—than any other Democratic candidate.
