Improvements in pork production efficiency have always been important to maintaining a viable and competitive Canadian pork sector. Because increasing production costs often outstrip increases in farm gate commodity values, improved production efficiencies assume an important role in maintaining farm profitability. In the past, combining environmental sustainability with positive economic spin-offs for the farm has been difficult. In many cases, pork producers have implemented conservation practices, with little return on investment. An overall industry willingness to provide this societal service has resulted in the generation of a forward thinking and environmentally responsible industry. The emergence of a new area of environmental sustainability, greenhouse gas management, has the potential to offer some quantity of cost recovery for environmental sustainability and potentially increase farm income.
