New study suggests federal government underreports greenhouse gases from forestry sector

Canada's forestry sector is responsible for far more greenhouse gas emissions than show up in official tallies, potentially leading to policies that aren't in line with the country's climate goals, a new study suggests.

The peer-reviewed study, published in the academic journal Frontiers in Forests and Global Change, found that annual greenhouse gas emissions attributable to forestry between 2005 and 2021 were, on average, nearly 91 million tonnes of carbon dioxide equivalent — which would put the sector on par with emissions from the agricultural sector.

By contrast, Canada's official inventory report shows the forestry sector acting as a carbon sink, which means it absorbs more carbon from the air than it sends into the atmosphere. The report has the sector absorbing an average of five million tonnes of carbon dioxide equivalent annually over the same period.
