Those subsidies gave rise to a booming market, to the point that wood is now Europe’s largest renewable energy source, far ahead of wind and solar. But today, as demand surges amid a Russian energy crunch, whole trees are being harvested for power. And evidence is mounting that Europe’s bet on wood to address climate change has not paid off. Forests in Finland and Estonia, for example, once seen as key assets for reducing carbon from the air, are now the source of so much logging that government scientists consider them carbon emitters....

E.U. official research could not identify the source of 120 million metric tons of wood used across the continent last year — a gap bigger than the size of Finland’s entire timber industry. Researchers say most of that probably was burned for heating and electricity...."
