GRUNDY COUNTY, Tenn.—For much of human history, the way to make money from a tree was to chop it down. Now, with companies rushing to offset their carbon emissions, there is value in leaving them standing.
The good news for trees is that the going rate for intact forests has become competitive with what mills pay for logs in corners of Alaska and Appalachia, the Adirondacks and up toward Acadia. That is spurring landowners to make centurylong conservation deals with fossil-fuel companies, which help the latter comply with regulatory demands to reduce their carbon emissions.
For now, California is the only U.S. state with a so-called cap-and-trade system that aims to reduce greenhouse gasses by making it more expensive over time for firms operating in the state to pollute. Preserving trees is rewarded with carbon-offset credits, a climate-change currency that companies can purchase and apply toward a tiny portion of their tab.
But lately, big energy companies, betting that the idea will spread, are looking to preserve vast tracts of forest beyond what they need for California, as part of a burgeoning, speculative market in so-called voluntary offsets.
