![]() Scenarios based on practices were modelled to understand the scale of impact reduction possible. ![]() To understand the impact of the choices in practices, the analysis compared regionalised provincial average results. The water footprint was strongly linked to geography and the use of irrigation. Potential burdens on human health were dominated by ammonia emissions. Potential impacts on ecosystem quality were mostly caused by feed production land use with some potential ecotoxicity. ![]() In line with existing publications, the environmental LCA found that the main sources of greenhouse gases were emitted at the farm, with enteric fermentation, manure management and feed production. The link you mention refers to version 1.3 where this was indeed different. E.g.: a 2 (a is independent parameter) b a+1 (b is dependent parameter). This paper summarises the methodology, results and conclusions. it is not that complicated: A dependent parameter depends on other parameters. As part of its initiatives to improve the environmental performance of dairy production in Canada, the Dairy Farmers of Canada commissioned in 2010 a full environmental and socio-economic life cycle assessment (LCA) for the production of milk across Canada. ![]()
