Living in a New York City apartment on a journalist's budget is one way to rein in your greenhouse gas emissions. But a woman in Olympia, Washington, has it all over our two editors who are vying for green bragging rights. Dee Williams lives in a standalone house, not an apartment. But her house measures only 84 square feet.
The tiny house incorporates recycled materials and cost about $10,000 to build. It has heat, electricity and a composting toilet, but no running water.
Williams says she wanted to reduce her impact on the planet, and didn't feel right about spending a lot of time and money on a house when people in other parts of the world have so little. —Dawn Stover
