Description

The scope of this protocol is limited to on-farm reductions of emissions from nitrogen sources and fuel use associated with the management of synthetic fertilizer, manure fertilizer and crop residues. Greenhouse gas (GHG) reductions associated with carbon sequestration in the soil and off-site emission reductions affected by the manufacture and distribution of nitrogen fertilizers are excluded from the protocol. The exclusion of off-site reductions of fertilizer manufacturing increases conservativeness in emission reduction calculations and limits the scope of quantification to those sources, sinks and/or reservoirs for which data are readily available.

Description

Agricultural activities, including the production of livestock, result in greenhouse gas emissions into the atmosphere. Beef cattle, in particular, release methane (CH4) as a result of the digestion of feed materials in the rumen. These emissions are called enteric emissions and are a contributor to greenhouse gas emissions from agricultural activities. Methane and nitrous oxide (N2O) emissions are also generated from manure storage and handling within beef cattle operations. These emissions are called manure emissions. This protocol for reducing greenhouse gas emissions in fed cattle addresses digestion and manure storage/handling sources of livestock greenhouse gas emissions. The protocol allows users to quantify greenhouse gas reductions using scientifically valid methodology and emission factors resulting from alterations in feeding strategies and other technologies in the finishing stages of beef cattle at feedlots in Alberta.
