Eggs are an increasingly significant source of protein for human consumption, and the global poultry industry is the single fastest-growing livestock sector. In the context of international concern for food security and feeding an increasingly affluent human population, the contribution to global greenhouse-gas (GHG) emissions from animal protein production is of critical interest. We calculated …
The US egg industry has evolved considerably over recent decades by incorporating new technologies and production practices. To date, there has been no comprehensive assessment of the resource demand and environmental effects of these changes. This study quantifies the environmental footprint of egg production supply chains in the United States for 2010 compared with 1960 …
The environmental impacts of 2 alternative UK broiler production systems that aim to improve bird welfare (a lower stocking density indoor system and the same system combined with heat exchangers for ventilation air) were compared with the baseline standard indoor system of broiler production. Furthermore, the environmental impacts of egg production in the conventional battery …
This article presents a tool and data for calculation of the carbon footprint of rendering operations in North America, quantifying Scope 1 (direct) and Scope 2 (indirect) greenhouse gas emissions. Scope 3 (life cycle) emissions are not included. According to the sample data, in one year an average-size rendering plant in North America processes 100,000 …
Enzymes are widely used in feed to improve utilization of nutrients and it is generally acknowledged that phytases, by improving …
Food systems—in particular, livestock production—are key drivers of environmental change. Here, we compare the contributions of the global livestock sector …
Food provides energy and nutrients, but its acquisition requires energy expenditure. In post-hunter-gatherer societies, extra-somatic energy has greatly expanded and …
The aim of this study was to apply a life cycle assessment (LCA) method, from cradle to gate, to quantify the environmental burdens per 1,000 kg of eggs produced in the 4 major hen-egg production systems in the United Kingdom: 1) cage, 2) barn, 3) free range, and 4) organic. The analysis was based on …
The production, transport and processing of food products have significant environmental impacts, some of them related to climate change. This …
Both the process of carbon footprinting and carbon labelling of food products are currently voluntary in the UK. Both processes derive from the UK’s policy for sustainable development and in particular, the UK’s Framework for Environmental Behaviours that strongly advocates a social marketing approach towards behavioural change. This paper examines whether carbon footprinting and labelling …
The food system appropriates over 30% of all ice-free land, 70% of available freshwater and 20% of energy. Sustainable food …
Environmental life cycle assessment (LCA) has developed fast over the last three decades. Whereas LCA developed from merely energy analysis …
This paper reviews estimates of food related greenhouse gas (GHG) emissions at the global, regional and national levels, highlighting both …
In the present study, the application of life cycle assessment (LCA) for the comparison of two egg packages, from polystyrene …
Despite significant recent public concern and media attention to the environmental impacts of food, few studies in the United States …
