    Greening Christmas

    I love the smell of balsam and firs and decorating holiday cookies – preferably with the sound of popular holiday standards in the background. I even enjoy shopping for and wrapping carefully chosen presents in seasonal papers festooned with huge bows. So when my hosts, this week, asked what I wanted to see during my visit, the answer was simple. Take me to one of Germany’s famed Christmas markets. And literally within a couple hours of my plane’s landing, they were already ushering me into the first of what would be a handful of such seasonal fairs. But as I also quickly learned, this first was an unusual one: a "green" bazaar.

    Countering Copenhagen’s Carbon Footprint

    The United Nations’ Climate Change Conference, beginning Monday (Dec. 7), will draw legions of people to Copenhagen from 192 countries. Traveling to Denmark — sometimes from the far corners of the Earth — will expend huge amounts of energy. And spew plenty of the very carbon dioxide that the meeting negotiators are trying to rein in. So several bodies will be offsetting the carbon footprint of this gathering — with bricks. Or brick ovens, anyway.
