Knowledge for better food systems

Showing results for: Life cycle analysis

8 October 2018

The Food and Agriculture Organisation of the United Nations has published guidelines for the assessment of nutrient flows and their associated environmental impacts in livestock supply chains. The guidelines are aimed at people and organisations who already have a good working knowledge of life cycle assessment of livestock systems, and are intended to promote consistency through defining calculation methods and data requirements.

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.

FCRN member Nicole Tichenor Blackstone of Tufts University has recently authored a paper that compares the environmental impacts of three healthy eating patterns recommended in the Dietary Guidelines for Americans. The vegetarian eating pattern had lower impacts than the US-style and Mediterranean-style eating patterns in all six impact categories considered.

Alcohol production, packaging and transport in Sweden has a carbon footprint of 52 kg CO2 eq. per person and accounts for around 3% of dietary emissions, according to a new paper by FCRN member Elinor Hallström. Per litre of beverage, wine, strong wine and liquor have higher carbon footprints than beer. This study does not include emissions from retail or consumer activities.

FCRN member Ramy Salemdeeb of Ricardo Energy & Environment used Life Cycle Assessment to calculate 14 different categories of environmental impacts of three food waste management options: incineration, composting and anaerobic digestion. Composting had the lowest impacts in 7 out of the 14 impact categories.

This book, edited by Fabricio Chicca, Brenda Vale and Robert Vale, calculates the environmental impacts of lifestyles around the world. FCRN readers may be particularly interested in Chapter 10, which looks at food.

In this paper, FCRN member Michael Martin examines the environmental impacts of various Swedish dietary choices across a wide range of environmental impact categories, paying particular attention to the trade-offs between impact categories.

Targetting the food-energy-water nexus, this review by FCRN members Eugene Mohareb and Martin Heller and colleagues summarises the energy implications of various types of urban agriculture. The goal of their research is to identify resource efficiency opportunities while increasing urban food production.

A new paper titled Distributions of emissions intensity for individual beef cattle reared on pasture-production systems details a new method, developed at the North Wyke Farm Platform, of assessing grazing livestock impacts and benefits at the level of individual animals.

An ad used by Arla Foods to promote their organic milk has been banned as it used the "misleading" claim that its production is "good for the land".

In this paper FCRN member Afton Halloran and colleagues Hanboonsong, Roos and Bruun present a life cycle assessment of insect farming, based on their research on cricket and broiler farms in north-eastern Thailand as well as a socio-economic impact analysis of this production.

This research calculates the carbon footprint of a meal to give a tangible example, aimed at the public in the US, about how daily food decisions can affect deforestation and greenhouse gas emissions (GHGe). The study uses a life-cycle assessment (LCA) approach that takes into account GHGe arising from the conversion of mangrove to cattle pastures and mangrove to shrimping ponds as well as from forests to pasture (cattle induced deforestation).

This research links the self-reported Food Frequency Questionnaire (FFQ) data of Swedish participants, to Life Cycle Assessment (LCA) data of carbon footprint for food products. The results of this study indicate that a self-selected diet low in diet related greenhouse gas emissions (GHGE) provides comparable intake of nutrients as a diet high in GHGE, and adheres to dietary guidelines for most nutrients.
