An evaluation of life cycle assessment of European milk production

Avaliação do Ciclo de Vida na bovinocultura leiteira e as oportunidades ao Brasil

“…Ademais, é válido considerar que o manejo pelo produtor pode ter maior efeito do que o tipo de sistema de produção (YAN; HUMPHREYS; HOLDEN, 2011). Apesar dessas incertezas, os levantamentos efetuados nesta revisão podem indicar oportunidades e processos em que é possível reduzir os impactos potenciais da bovinocultura leiteira no Brasil.…”

Benchmarking the environmental performance of dairy farming systems

“…The goal is to reduce the environmental impact of dairy farming systems. The environmental impacts included (scope) are climate change, acidification, eutrophication, energy use and land use, being important impact categories in the dairy sector (Thomassen and De Boer, 2005;Yan et al, 2011). As the majority of these environmental impacts relate to the agricultural stage, including the production of purchased feed and processes on the dairy farm, the system boundary was defined from cradle-to-farm gate (see Figure 1.3).…”

“…Over the past few years the number of LCAs on dairy products have increased enormously (e.g. Cederberg, 1998;Thomassen and De Boer, 2005;Yan et al, 2011). The mostly examined impact categories are: climate change, land use, energy use, acidification, eutrophication and the system boundary is often defined from cradle-to-farm gate (on-farm processes, e.g.…”

“…These environmental indicators are generally derived from a nutrient balance approach or a life cycle assessment Thomassen and De Boer, 2005;Yan et al, 2011).…”

“…Over the past few years the number of LCAs on dairy products have increased enormously (e.g. Cederberg, C. 1998; Thomassen and De Boer, 2005;Yan et al, 2011). However, studies suggested that collection of data required to perform an LCA appears difficult and is more time consuming than, for example, performing an NB (Thomassen and De Boer, 2005).…”
