Summary Background Sustainable diets are intended to address the increasing health and environmental concerns related to food production and consumption. Although many candidates for sustainable diets have emerged, a consistent and joint environmental and health analysis of these diets has not been done at a regional level. Using an integrated health and environmental modelling framework for more than 150 countries, we examined three different approaches to sustainable diets motivated by environ...

Background Evidence on whether healthy diets are more expensive than current diets is mixed due to lack of robust methodology. The aim of this study was to develop a novel methodology to model the cost differential between healthy and current diets and apply it in New Zealand.

In the context of planetary boundaries on the one hand and the need for human development (in its widest sense) on the other, what role – if any – do farmed animals play in a sustainable food system? If they do have a role, which systems and species are to be preferred, in which contexts, at what scale and at what level of overall production and consumption? How could the required changes happen?

Abstract This paper presents the results of a systematic literature review of greenhouse gas emissions for different food categories from life cycle assessment (LCA) studies, to enable streamline calculations that could inform dietary choice. The motivation for completing the paper was the inadequate synthesis of food greenhouse gas emissions available in the public domain. The paper reviewed 369 published studies that provided 1718 global warming potential (GWP) values for 168 varieties of fres...

This paper explores how New Zealand should address agricultural greenhouse gas emissions: methane and nitrous oxide. The starting point is the internationally agreed-upon goal of limiting global warming to below two degrees, and New Zealand’s commitment to contribute its ‘fair share’ to the international climate-change mitigation effort. The report focuses on the role of mitigating biological agricultural emissions within that, and how New Zealand could most cost-effectively mitigate its own emi...

The livestock sector supports about 1.3 billion producers and retailers, and contributes 40-50% of agricultural GDP. We estimated that between 1995 and 2005, the livestock sector was responsible for greenhouse gas emissions of 5.6-7.5GtCO(2)e yr(-1). Livestock accounts for up to half of the technical mitigation potential of the agriculture, forestry and land-use sectors, through management options that sustainably intensify livestock production, promote carbon sequestration in rangelands and red...

Diets link environmental and human health. Rising incomes and urbanization are driving a global dietary transition in which traditional diets are replaced by diets higher in refined sugars, refined fats, oils and meats. By 2050 these dietary trends, if unchecked, would be a major contributor to an estimated 80 per cent increase in global agricultural greenhouse gas emissions from food production and to global land clearing. Moreover, these dietary shifts are greatly increasing the incidence of t...

The greenhouse gas (GHG) emissions embodied in 66 different food categories together with self-reported dietary information are used to show how consumer choices surrounding food might lead to reductions in food-related GHG emissions. The current UK-average diet is found to embody 8.8kgCO2eperson−1day−1. This figure includes both food eaten and food wasted (post-purchase). By far the largest potential reduction in GHG emissions is achieved by eliminating meat from the diet (35% reduction), follo...
