Nearly a dozen environmental groups are calling on the federal government to expand its review of Canada’s forestry sector emissions, saying the current scope fails to address their concerns about underreporting. In an open letter, the groups say the federal government’s review must consider how forestry emissions are estimated in the first place. The letter, signed by representatives from 11 environmental groups including Nature Canada, says the review’s scope undermines its credibility. The letter comes after the federal environment commissioner issued a report last year recommending Ottawa initiate an independent review to look at how it estimates and reports on emission related to logging. In response to that report, the government agreed that independent review was important but noted that the science underlying its carbon reporting was peer-reviewed.
