This paper describes how deep public divisions over climate change are unrelated to differences in how well ordinary citizens understand scientific evidence on global warming. Contrary to what many believe, members of the public who score the highest on a climate-science literacy test are the most politically polarized on whether human activity is causing global temperatures to rise.

This is a special issue introduction, providing a brief overview of the CSES project (Coalition for Sustainable Egg Supply (CSES)) to serve as an introduction for the papers that follow in this volume of Poultry Science. The full issue focuses on providing empirical information on the sustainability of commercial-scale egg production. 

This research from Duke University presents policymakers with a more accurate framework for estimating the costs of a broad range of health, climate and environmental damages linked to emissions from fossil fuels, industry, biomass burning and agriculture.

This study compared the impact that a 20 per cent sales tax and a 20 cents per litre excise tax on beverages such as carbonated non-diet soft drinks, cordials and fruit drinks would have on moderate and high consumers. It found that although high consumers of sugar-sweetened beverages have the least elastic demand, they drink so much that they are up against household budget limits, and therefore adding tax would bring down their consumption.

Volume 57.2 of Development - the quarterly journal of the Society for International Development - was produced in the lead-up to the Second International Conference on Nutrition (ICN2). It explores the relationship between nutrition, food security and sustainable agriculture.

Although not specifically focusing on food sustainability this paper is of relevance for the larger debate on alternative models of sustainable development. The paper concludes that our modern material lifestyles are failing to make us happier, are damaging our health, are no longer sustainable and cost the overall economy tens of billions of pounds every year.

Author summary This article provides a synopsis of the main research findings from the book “Environmental protection with knife and fork – the ecological rucksack of nutrition in Germany”, various peer-reviewed publications and as well as the underlying dissertation of the author. The first part of the article presents an overview of current challenges in the transdisciplinary field of nutrition, environment and public health. After a brief presentation of the methods, in the results section life cycle assessment results are presented on product and consumption levels and possible courses of action are derived – with a special focus on different diets and reduced food losses.

This special issue focuses on the implications of climate change for food safety. The introductory paper to the series briefly summarizes the current state of knowledge.   It states that:

This systematic review evaluates the environmental impact of 49 dietary scenarios and shows that shifts in consumption could reduce diet-related GHG emissions and land use demand by up to 50%. The paper states that the amount and type of meat in the diet mainly affects the improvement potential. The research also identifies and addresses research gaps and key methodological aspects influencing outcomes.
