This study, co-authored by Table member Dr Toni Meier, measures the nutritional value, environmental impacts and food waste associated with catering facilities in Hesse, Germany. The project examined company canteens, prison kitchens and a restaurant run by a vocational training institute. 

This paper provides an overview of the environmental impacts of pet food production at the global level. It finds that, depending on the data source used, dry pet food production accounts for 1.1-2.9% of global agricultural emissions, 0.8-1.2% of global agricultural land use, and 0.2-0.4% of agricultural water extraction.

This paper calculates externalities - specifically, costs of climate change from greenhouse gas emissions - of categories of food produced in Germany. It finds that animal-based products (both conventional and organic) have the highest external climate costs (€2.41/kg product), followed by dairy products (€0.24/kg product for conventional and €0.19/kg product for organic), and finally plant-based products (€0.04/kg product for conventional and €0.02/kg product for organic).

This paper, co-authored by FCRN member David Cleveland, aims to quantify the animal welfare and environmental implications of replacing egg-based mayonnaise with plant-based mayonnaise and replacing eggs with tofu, using a case study from the University of California, Santa Barbara. 

This paper, co-authored by the FCRN’s Tara Garnett and John Lynch of the Oxford Livestock, Environment and People programme, identifies and discusses four challenges associated with attributional life cycle assessment.

In this paper, FCRN member Michael MacLeod reports that global aquaculture produced around 0.49% of global greenhouse gas emissions in 2017 - a similar quantity to the emissions from sheep meat production. When emissions are measured per kg of edible product, the paper finds aquaculture to have low emissions intensity relative to meat from goats, cattle, buffalo and sheep and similar emissions intensity to meat from pigs and chickens.

This working paper from the World Resources Institute compares the carbon footprint of dairy from 13 different countries and pork from 11 countries. It uses a carbon opportunity cost approach to carbon footprinting, i.e. it accounts for carbon that is not stored in vegetation or soils because the land is being used to produce dairy or pork. 

This paper by FCRN member Daniel Tan finds that bioethanol derived from agave grown in semi-arid areas of Australia could have lower environmental impacts than biofuels derived from US corn and Brazilian sugarcane. Agave is widely grown in Mexico to make the alcoholic drink tequila. 

This blog post by John Lynch of the Oxford Livestock, Environment and People programme explains how GWP* can be used to describe the warming effect of both short- and long-lived greenhouse gases, particularly when applied to livestock.
