The World Resources Institute has published a new report outlining solutions for feeding 10 billion people without increasing emissions, fueling deforestation or exacerbating poverty.
This report finds that the ten largest US food and beverage manufacturers lack comprehensive strategies for effectively addressing obesity and diet-related diseases. Assessing a portfolio of the manufacturers’ products, the report classifies only 30% as “healthy”.
UK supermarket Tesco and wildlife NGO WWF have set up a four-year partnership to work on reducing the environmental impacts of food. They aim to halve the environmental impact of the average UK shopping basket, according to a metric that they will develop.
The global agricultural system doesn’t produce enough fruit, vegetables and protein to meet the nutritional needs of the world’s population, according to this paper. Meanwhile, grains, fats and sugars are overproduced, relative to what is needed for a healthy diet (defined in this paper as a diet in accordance with the Harvard Healthy Eating Plate (HHEP)).
The Engagement Migros development fund and the Swiss Federal Office for Agriculture have funded the creation of an app, MyFoodways, which aims to help consumers reduce food waste. The app provides personalised recipes suggestions and offers tips on storing food and using up leftovers. While the MyFoodways company is commercial, the app is free for users to download.
A new law requires that state institutions such as hospitals, nursing homes and prisons in California must provide a vegan menu option. The move has been welcomed by health and animal welfare campaigners.
FCRN member Eugene Mohareb of the University of Reading is the lead author on a paper that quantifies greenhouse gas (GHG) emissions associated with the US food supply chain. The paper argues that the majority of food system emissions could be best mitigated by urban areas and urban consumers (see below for definitions), rather by production side mitigation measures. The paper assesses how municipalities and urban dwellers might be able to contribute to deep, long-term emissions cuts along the food supply chain.
The New York-based Guarini Centre on Environmental, Energy and Land Use Law has released a report exploring the policies that US cities could use to reduce meat and dairy consumption. Three main categories of policy are proposed: informational (to raise public awareness of the health and climate implications of meat and dairy consumption), procurement policies for public institutions, and economic interventions to incentivise different purchasing patterns.
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.
