The Western Canadian Wheat Growers have calculated that the agriculture sector captures 100 megatonnes of carbon dioxide from the grain farmers grow, which amounts to about 30 megatonnes more than what the national inventory reports as GHGs emitted by the agricultural sector. The Western Canadian Wheat Growers have argued that when grain leaves the farm gate, they are net zero for GHGs. I would argue that they are a net carbon sink for 33 megatonnes of greenhouse gases, according to their report.
Could you comment on the Western Canadian Wheat Growers' calculations and also on giving credit to grain growers and the agricultural sector for constituting a net carbon sink?
