Documents that CBC News P.E.I. received through Freedom of Information show a large amount of the wood being used to heat more than 40 provincial buildings has come from forests that were cleared to become housing or farmland. …One report in the documents revealed that 86 per cent of the wood one contractor used between 2015 and 2018 came from land conversion — forests cleared for farmland or for housing. That concerns Gary Schneider, manager of the MacPhail Woods Ecological Project. “It can’t be sustainable, because we can’t continuously clear land,” he said. …When the Liberal government of Robert Ghiz started using wood to heat provincial buildings in 2008, the aim was to reduce reliance on furnace oil. A promise was made that only wood that had been harvested sustainably would be used in the low-emission wood-burning boilers.
