Unfortunately, the carbon offset market is constantly growing

It might seem difficult to chop down trees with one hand and sell climate absolution with the other, but the dubious math of carbon offsets makes it possible, at least for now. Trees drink in carbon dioxide, the stuff that heats the planet to dangerous levels. And except for Uncle Sam, no one in America owns as many trees as Seattle's Weyerhaeuser, America's largest logger. The company has long been the bete noire of environmentalists and is now using its 10.6 million acres of forest to declare that it has so many green credits that it can sell some to other companies, the Wall Street Journal recently reported. Weyerhaeuser claims its forests absorb 17 million metric tons of carbon annually. Its wood and other products could freeze another 18 million metric tons in place for years or decades. That more than offsets the 7.4 million metric tons of carbon that logging and other activities emit each year, Weyerhaeuser estimates.
