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.

Fresh fruit and vegetables deliberately withdrawn from the market and destroyed under the EU’s Common Agricultural Policy accounted for 5.1 Mt CO2 eq. in embedded production-stage emissions between 1989 and 2015, according to research by FCRN member Stephen Porter of the University of Edinburgh.

173 countries have agreed to halve emissions from the global shipping industry by 2050, compared to 2008 levels, in a non-binding deal arranged by the International Maritime Organisation. Saudi Arabia, the US and several other countries raised objections to the proposed emissions cuts. Shipping was not covered by the 2015 Paris agreement on climate change.

A new paper finds that a range of “ambitious but not unrealistic” climate mitigation options could, together, mean that using bioenergy with carbon capture and storage (BECCS) is not necessary for staying within 1.5°C of warming. Mitigation options considered include limiting population, lower meat consumption and use of lab-grown meat, lifestyle changes such as lower car use, electrification of energy end-use sectors, high efficiency manufacturing, agricultural intensification and mitigation of non-CO2 greenhouse gases.

This paper calculates country-level mitigation targets for agricultural non-CO2 greenhouse gases (GHGs) based on a variety of allocation methods. This study claims to be the first to calculate national mitigation contributions for the agricultural sector that are consistent with meeting the 2°C target.

A report by the European Academies’ Science Advisory Council finds that negative emissions technologies (NETs) have ‘limited realistic potential’ and cannot be relied upon to remove carbon at the rate envisaged in the Intergovernmental Panel on Climate Change (IPCC) scenarios for avoiding dangerous climate change.

This new study by FCRN member Paul Behrens and colleagues investigates the environmental impacts of a nationally recommended diet when compared to the national average diet for 37 nations across the world, including 9 middle income nations.

This Research Handbook, edited by Mary Jane Angelo, Fredric G. Levin and Anél Du Plessis, brings together scholars from across disciplines and across the globe (including FCRN member Jonathan Verschuuren) to untangle the climate-food web and critically explore the nexus between climate change, agriculture and law, upon which food security and climate resilient development depends. It is a useful introduction to the research which is being undertaken in the area of climate change and agricultural law.

Scientists from national academies across Europe are calling for urgent action on food and nutrition in a new independent report published by the European Academies’ Science Advisory Council (EASAC). This analysis can be relevant for policy-makers working on food, nutrition, health, the environment, climate change, and agriculture.

The planetary boundaries concept provides a theoretical upper limit on human activity which the planet is able to sustain without major perturbation to the current ‘Earth system’. Previously, nine planetary boundaries (PBs) have been proposed and recently Steffen et al. (2015) have updated these boundary definitions and assessed the current state of the position of human activity with respect to each boundary. In this article, researchers from a number of food, climate change, agricultural and environmental research institutions around the world build on this work by assessing the impact of agriculture on each PB status, based on a detailed literature review of the available research.
