Nine of the World's Most Promising Carbon-Neutral Communities
Building a Carbon Neutral Paradise eBoyIn the global race to reduce carbon emissions, these eco-minded communities, from Kansas to the Maldives, lead the pack. Here's how they're making their carbon footprints disappear "Carbon neutral" sounds pretty straightforward-simply remove as much carbon dioxide from the atmosphere as you put in. The trouble is, civilization began emitting CO2 when humans burned the first lump of coal about 4,000 years ago.

Today the fraction of carbon dioxide in the atmosphere is about 385 parts per million, roughly 30 ppm above the level deemed environmentally sustainable by many scientists and climate experts. If we continue emitting at our current rate, that number will climb to 450 ppm by 2050, putting the planet at serious risk of runaway climate change, with heat-trapping gases...
