PurposeThis paper investigates different methodologies of handling co-products in life cycle assessment (LCA) or carbon footprint (CF) studies. Co-product handling can have a significant effect on final LCA/CF results, and although there are guidelines on the preferred order for different methods for handling co-products, no agreed understanding on applicable methods is available. In the present study, the greenhouse gases (GHG) associated with the production of 1 kg of energy-corrected milk… Expand
The impact of various parameters on the carbon footprint of milk production in New Zealand and Sweden
The carbon footprint (CF) of milk production was analysed at the farm gate for two contrasting production systems; an outdoor pasture grazing system in New Zealand (NZ) and a mainly indoor housingExpand
Carbon footprint of dairy goat milk production in New Zealand.
TLDR
The aim of this study was to assess the cradle-to-farm gate carbon footprint of indoor and outdoor dairy goat farming systems in New Zealand, identifying hotspots and discussing variability and methodology, although only results for greenhouse gas emissions are presented. Expand
A Life Cycle Assessment Application: The Carbon Footprint of Beef in Flanders (Belgium)
Although several international carbon footprint (CF) calculation initiatives have been developed, studies that focus specifically on estimating the CF of beef are rather scarce. This chapterExpand
Method to assess the carbon footprint at product level in the dairy industry
Abstract A model to calculate the farm-to-customer carbon footprint (CF) for different dairy product groups is presented. As the largest share of the CF of dairy products occurs at farm level, it isExpand
Carbon footprint of milk production in Brazil: a comparative case study
PurposeLivestock production is a recognized source of environmental impact, and this sector indirectly involves approximately 5 million people in Brazil. Livestock production includes nearly 1.5Expand

PurposeMethodology of co-product handling is a critical determinant of calculated resource use and environmental emissions per kilogram (kg) product but has not been examined in detail for differentExpand
The interaction between milk and beef production and emissions from land use change – critical considerations in life cycle assessment and carbon footprint studies of milk
Two most critical factors to address in environmental system analysis of future milk production are 1) the link between milk and beef production, and 2) the competition for land, possibly leading toExpand
Effect of dairy production system, breed and co-product handling methods on environmental impacts at farm level.
TLDR
Impacts of climate change, climate change including the effects of land use and land use change (CC/LULUC), cumulative energy demand, eutrophication, acidification and land occupation, and co-product handling methods and impact categories were considered. Expand
Using Life Cycle Assessment methodology to assess UHT milk production in Portugal.
TLDR
Life Cycle Assessment methodology was considered for the environmental assessment of packaged UHT milk produced in Portugal, including simple, semi-skimmed and skimmed and cocoa milk from a cradle-to-gate perspective and showed that the production of the raw milk in the dairy farm is the main hot spot in almost all the categories under assessment. Expand
A case study of the carbon footprint of milk from high-performing confinement and grass-based dairy farms.
TLDR
Compared to recent reports that assess the carbon footprint of milk from average Irish, UK, and US dairy systems, this case study indicates that top-performing herds of the respective nations have carbon footprints 27 to 32% lower than average dairy systems. Expand

An operational method for the evaluation of resource use and environmental impacts of dairy farms by life cycle assessment.
TLDR
This study largely confirms previously published findings concerning the effect of production mode on impacts of dairy farms, but strikingly reveals that, for the set of farms examined, the contribution ofProduction mode to overall inter-farm variability of impacts was minor relative to inter-Farm variability within each of the two production modes examined.
