Canadian agricultural emissions are rising: up 22 percent since 1990. Agriculture produces about 11 percent of Canadian emissions.
4. Farm inputs are the problem. For thousands of years, humans practised agriculture but did not affect the atmosphere or climate. Over the past century, however, as farmers purchased more and more energy-intensive inputs, emissions have soared.
5. Nitrogen fertilizer is a huge problem. It is unique among human materials and processes in that it is a major source of all three main greenhouse gases: nitrous oxide (when used), carbon dioxide (in production), and methane (from its feedstock, natural gas). Canadian farmers have doubled nitrogen fertilizer tonnage since 1993.
6. Cattle emit methane, a greenhouse gas 28 times more powerful than carbon dioxide. Atmospheric methane concentrations have doubled in the past 100 years. Sources include fossil-fuel production, landfills, and cattle and other grazing livestock.

Governments must accelerate on-farm renewable-energy production; the development of low-emission battery-electric trucks, tractors, and other farm equipment; and energy-conserving retrofits of farm buildings.
