Mr. Speaker, in response to part (a), figure 5.1 reports emissions from the national inventory report of greenhouse gas sources and sinks in Canada. Livestock emissions are determined using a standard Intergovernmental Panel on Climate Change, IPCC, methodology and consist primarily of methane emissions from livestock production and manure management. The method tracks enteric methane emissions from livestock, mainly ruminants such as cattle and other ruminants, as well as methane and nitrous oxide emissions from manure management. This method is based on an internationally accepted standard, which has been modified to reflect Canadian climate, livestock types and management practices. It is further adapted based on empirical data collected from studies across Canada.
In response to part (b), data for the modeling comes primarily from the Statistics Canada census of agriculture, as well as the biennial livestock survey from Statistics Canada, which describes the population, age and gender distribution of livestock types. Additional data on livestock productivity and manure management practices come from Statistics Canada surveys, as well as from expert opinion surveys.
In response to part (c), figure 5.1 describes the emissions as of 2021. The national inventory tracks annual emissions, starting in 1990. The latest data point now available is 2022, released in early May.
In response to part (d), the data can be broken down by livestock group. Livestock groups include dairy, beef, sheep, swine and other minor animal categories for enteric methane as well as manure management emissions of methane and nitrous oxide.
In response to part (e), no, the information is for farms only. Emissions from processing facilities would be included in the industry sector.
