Canada’s continent-spanning forest used to remove massive amounts of CO2 from the air each year. It was a hugely valuable “carbon sink”, slowing the pace of climate change and benefiting our logging industry. But that carbon sink has steadily collapsed to the point where the forest now emits CO2. That adds fuel to our accelerating climate crisis, and spells trouble for Canadian logging. That is the grim story told by the data in Canada’s latest National Inventory Report (NIR). I’ve dug into that data to create a series of charts that illustrate what’s happening in Canada’s managed forest, and what it means for our climate emergency and our logging industry. …Over the last two decades, the once great carbon sink has steadily drained away. It’s now gone, and the balance in the forest has tipped to emitting CO2 instead.
