FCRN member Dr Rosemary Green of the London School of Hygiene & Tropical Medicine has published a paper that calculates the greenhouse gas (GHG) emissions and water use associated with five dietary patterns in India. As shown below, GHG emissions per capita are highest for the “rice and meat” dietary pattern (at 1.2 tonnes CO2 eq. per year) and lowest for the “wheat, rice and oils” pattern (at 0.8 tonnes CO2 eq. per year). For comparison, per capita dietary GHG emissions in the UK have been estimated at 2.6 tonnes CO2 eq. per year for high meat eaters and 1.1 tonnes CO2 eq. per year for vegans (Scarborough et al., 2014). Water use is highest for the “wheat, rice and oils” pattern and lowest for the “rice and low diversity” pattern.
This book, by Peter Jackson et al., looks at different types of convenience foods and why consumers use them, and seeks to apply its findings to policies for healthy and sustainable diets.
FCRN member Martin Heller of the Centre for Sustainable Systems at the University of Michigan has calculated the greenhouse gas emissions (GHGEs) and energy demand associated with the diets of individuals in the US, based on a one day dietary recall survey. The highest-emitting 20% of diets are responsible for 46% of diet-related GHGEs, while the lowest-emitting 20% of diets cause 6% of diet-related GHGEs. The food types causing the highest percentage of GHGEs are meats (57%), dairy (18%), beverages (6%) and fish and seafood (6%).
This paper estimates greenhouse gas emissions (GHGEs) associated with the food purchased by US households (based on survey data) and examines the links between food GHGEs and demographic factors. It suggests that education on the links between food and climate could be targeted at more educated and more affluent consumers, since their research shows (see below) that the these households have more GHGE-intensive dietary patterns.
The FCRN’s Tara Garnett is featured in this video by UK climate website Carbon Brief, which discusses how farmers could reduce the carbon footprint of beef production. Tara points out that production-side measures only go so far, and that consumption changes are needed as well.
This book, by Ludovica Principato, reviews information on consumer-level food waste, including the factors and behaviours affecting food waste levels, policies and initiatives.
The UK waste charity WRAP has recently reported that hotels could save $7 for every $1 invested in reducing food waste. The report studied 42 hotels in 15 countries and identified winning strategies that included: “measure the food waste, engage staff, rethink the buffet, reduce food overproduction, and repurpose excess food”. 70% of hotels managed to recoup their investments within one year, and 95% within two years.
The Food and Agriculture Organization of the UN (FAO) has published a report titled, ‘Regional Overview of Food Security and Nutrition,’ focused on Asia and the Pacific. Key messages from the report highlight that the fight against hunger is slowing, but malnutrition and stunting among children below the age of five remains high.
The Sackler Institute for Nutrition Science and Unilever partnered to host a workshop on sustainable nutrition. Researchers (including the FCRN’s Tara Garnett) gathered at the LCIRAH center in London to translate current findings from research on sustainability, food systems, nutrition and diet into actions that can effectively be implemented by Unilever through its brands, products and services.
This new paper by FCRN member Elin Röös , the FCRN’s Tara Garnett and colleagues explores the following questions: What would be the implications, for land use and greenhouse gas emissions, if our global population moved away from eating beef and other ruminant meats and switched mostly to chicken? What if we all went vegan? What if all our meat demand were met by artificial meat? Or what if, in an attempt to avoid ‘feed-food’ competition, we limited our consumption of animal products to what we could obtain by rearing animals on grasslands and feeding them byproducts and food waste?
The Food Citizenship report is the result of a ten month inquiry led by the New Citizenship Project with the Food Ethics Council, working with six organisations across the food system to explore a future ‘Citizen’ food system. It explores what could happen if the key players in the food system switched from a consumer to a citizen mindset, generating ideas and testing new approaches to food citizenship.
Recognising that changing what people eat can make a major contribution to the environmental performance of the food system, the new and updated Livewell Plates in this report illustrate the minimal dietary changes required to reach the 2 °C climate target. The report presents simple steps – such as eating more plants, legumes and grains – that could help cut food-related greenhouse gas emissions by 30% by 2030.
This master thesis study from the London School of Economics shows how consumers are 56% less likely to order a plant-based dish when it is labelled vegetarian and categorised in a separate section on menus
The EAT-Lancet Commission on Food, Planet, Health brings together 20 world-leading scientists from across the globe to reach a scientific consensus that defines a healthy and sustainable diet. The commission’s report will be published by The Lancet in Spring 2018.
