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… 

Carbon footprint of dairy goat milk production in New Zealand.

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.

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 chapter

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 1.5

Application of life cycle assessment to sheep production systems: investigating co-production of wool and meat using case studies from major global producers

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 different

A case study of the carbon footprint of milk from high-performing confinement and grass-based dairy farms.

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.



System expansion and allocation in life cycle assessment of milk and beef production

Background, Goal and ScopeSystem expansion is a method used to avoid co-product allocation. Up to this point in time it has seldom been used in LCA studies of food products, although food production

Life cycle inventory of 23 dairy farms in south-western Sweden

In this study, data on resource use and emissions for dairy farms in southwestern Sweden were collected and analysed with Life Cycle Assessment (LCA) methodology. The purpose of the study was to gain

Environmental Improvement Potentials of Meat and Dairy Products

The report is a scientific contribution to the European Commission's Integrated Product Policy framework, which seeks to minimise the environmental degradation caused throughout the life cycle of

Life cycle assessment (LCA) of industrial milk production

A Life Cycle Assessment (LCA) was carried out for milk production extending from the origin of the inputs to the agricultural step to the consumer phase and the waste management of the packaging.

An operational method for the evaluation of resource use and environmental impacts of dairy farms by life cycle assessment.

Comparing the environmental impacts of pasture-based and confinement-based dairy systems in Nova Scotia (Canada) using life cycle assessment

A life cycle assessment (LCA) of dairy systems in Nova Scotia was conducted to compare environmental impacts of typical pasture and confinement operations. Data on material and energy inputs and
