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.

FCRN member David Cleveland uses the University of California as a case study and finds that integrating climate and food policies could contribute substantially to reducing institutional greenhouse gas emissions by accounting for Scope 3 emissions (which would include emissions from food purchased by the institution).

This report from the international non-profit Institute for Agriculture and Trade Policy examines the climate impacts of large dairy corporations. It finds that greenhouse gas emissions from the 13 largest dairy companies have increased by 11% over the last two years, alongside an 8% increase in milk production, and that none of these corporations has published plans to cut total emissions in their dairy supply chains.

This blog post from US think tank The Breakthrough Institute examines uncertainties around the environmental impacts of cultured meat. It points out that estimates of the carbon footprint of cultured meat are highly variable, and that the impacts of switching to cultured meat depend on what it is replacing in the diet (e.g. beef, poultry, plant-based meats or tofu).

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.

FCRN member Erasmus zu Ermgassen has co-authored this paper, which calculates variations in the carbon footprint of soy products grown in different regions of Brazil. It finds that soy from certain areas associated with loss of natural vegetation has a carbon footprint per unit of product six times higher than the average carbon footprint of Brazilian soy. It also finds that soy products imported by the European Union are more likely to be from regions linked to deforestation than soy exported from Brazil to other places, such as China.

This paper by FCRN member Diego Rose estimates that 16% of adults in the United States might be receptive to changing their diet if national dietary guidance were to include information about environmental sustainability. It also estimates the impacts of a range of different dietary changes for those people on greenhouse gas emissions, dietary quality and dietary costs.

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.

7 April 2020

This paper uses several simple emissions scenarios to illustrate how GWP* (as opposed to GWP100) can report the warming created by both short-lived greenhouse gases such as methane (CH4) and long-lived greenhouse gases such as carbon dioxide (CO2).

This book by Sarah Bridle provides an accessible outline of the links between climate change and food: both the climate impacts of producing food, and the impacts of climate change on farming.

This systematic review looks at dietary patterns and food sustainability in the United States. It estimates that the healthy US-style diet recommended by the Dietary Guidelines for Americans is associated with similar or higher levels of greenhouse gas emissions, energy use and water use compared to the current US diet.

Our World in Data has published this piece, which breaks down the extent to which the differences in carbon footprints of food categories can be attributed to methane, a short-lived greenhouse gas which has attracted controversy over how its climate impact is measured.

This e-book, which has been translated into English, sets out the carbon, water and ecological footprints of foods and culinary preparations (items composed of more than one ingredient) consumed in Brazil.

This paper by FCRN member Jono Drew investigates whether healthy and climate-friendly diets might vary from global recommendations in the context of New Zealand (using food carbon footprints specific to New Zealand, where possible). It finds that shifting diets towards whole plant foods (such as vegetables, fruits, legumes, and whole grains) and away from red and processed meat would have large health and climate benefits, consistent with recent global recommendations.

Online conferences have the advantage of reducing carbon emissions from travel, particularly air travel, but they can be less convenient when it comes to networking and developing personal connections. The November meeting of the European Biological Rhythms Society tried to fix this by inviting psychologists to develop remote ways of encouraging networking.

FCRN member Christian Reynolds has co-authored this paper, which finds that in Japan, differences in the carbon footprint of household food consumption are driven by what the paper describes as “unexpected” food categories: the households with higher food carbon footprints spend more on restaurant food, fish, vegetables, alcohol and confectionary.
