Energy justice:A conceptual review

Energy justice has emerged as a new crosscutting social science research agenda which seeks to apply justice principles to energy policy, energy production and systems, energy consumption, energy activism, energy security and climate change. A conceptual review is now required for the consolidation and logical extension of this field. Within this exploration, we give an account of its core tenets: distributional, recognition and procedural. Later we promote the application of this three-pronged approach across the energy system, within the global context of energy production and consumption. Thus, we offer both a conceptual review and a research agenda. Throughout, we explore the key dimensions of this new agenda – its evaluative and normative reach – demonstrating that energy justice offers, firstly, an opportunity to explore where injustices occur, developing new processes of avoidance and remediation and recognizing new sections of society. Secondly, we illustrate that energy justice provides a new stimulating framework for bridging existing and future research on energy production and consumption when whole energy systems approaches are integrated into research designs. In conclusion, we suggest three areas for future research: investigating the non-activist origins of energy justice, engaging with economics, and uniting systems of production and consumption

Manganese levels in infant formula and young child nutritional beverages in the United States and France: Comparison to breast milk and regulations

Exposure to high levels of manganese (Mn) in children has recently been associated with adverse neurodevelopmental effects. Current infant formula regulations for Mn content were set between 1981 (United States), 2006 (European Union, France), and 2007 (Codex Alimentarius) prior to the publication of much of the growing body of research on the developmental neurotoxicity of Mn. In this study, we sought to measure the concentrations of Mn in some infant formulas and young child nutritional beverages available on the United States (US) and French markets using ion beam analysis by particle induced X-ray emission (PIXE) spectrometry and then compare the analytical results to concentrations reported in the literature for breast milk and applicable infant formula regulations and guidelines. We were particularly interested in measuring Mn concentrations in product types for which there is very little data from previous surveys, especially soy-based, rice-based, goat-milk based, chocolate-flavored, and nutritional beverages for young children that are not regulated as infant or follow-on formulas (e.g. "toddler formulas" and "toddler powders"). We purchased 44 infant formulas and young child nutritional beverage products in the US and France with varying protein sources (cow-milk, goat-milk, soy, rice) labelled for birth to 3 years. We selected these samples using maximum variation sampling to explore market extremes to facilitate comparisons to regulatory limits. Since this sampling method is non-probabilistic, other inferences cannot be made beyond this set of samples to the overall markets. We used ion beam analysis to measure the concentrations of Mn in each product. The range of measured Mn concentrations in the products is 160-2,800 μg/L, substantially higher than the 3-6 μg/L mean Mn concentration reported in human breast milk. All products satisfied national and Codex Alimentarius Commission (CAC) international standards for minimum Mn content in infant formulas; however, 7/25 of the products purchased in the US exceeded the CAC Guidance Upper Level of 100 μg Mn/kcal for infant formula
