Fig. 4: Canada’s NGHGI CO₂ emissions and removals compared with the 2023 Canadian fires.

Lines show the annual net emissions or removals from managed forest land (green), harvested wood products (brown), natural disturbances that are not counted towards Canada’s emissions (red) and the economy-wide net CO₂ emissions (grey). The top-down estimates of the 2023 CO₂ + CO fires emissions over managed land are shown in black. Total CO₂ emissions, harvested wood products and forest land emissions and removals were obtained from Table A11-1 of the NGHGI³², whereas natural disturbances were obtained from Table 6-5 of the NGHGI. All quantities presented are in units of teragrams of carbon (1 TgC = 1 MtC = 1,012 gC), which can be converted to units of megatonnes of CO₂ (MtCO₂) by multiplying by a factor of 3.664.
