This paper provides the first estimate of energy and material flows in the world’s 27 megacities (cities with over 10 million inhabitants). These megacities are home to 6.7 per cent of the world's population, but consume 9.3 per cent of global electricity and produce 12.6 per cent of global waste. The authors establish statistical relations for energy use, transport, water use, waste and so forth and factors such as average temperature, urban form, level and type of economic activity, and population growth.  This allows the researchers to evaluate which cities have high versus low levels of consumption and which ones make efficient use of resources.

In a digital studio at Harvard sixty people from 30 countries join Michael Sandel in this Radio 4 show, to discuss the philosophical issues underlying the world's response to climate change.

The report Life cycle assessment of tap water: Analysis and comparison with other beverages traces the entire life cycle from water catchment/extraction to serving it up in a glass. The report compares tap water with mineral water and other beverages and shows (unsurprisingly) that from an environmental point of view, tap water is preferable to bottled water and all other beverages. The report was produced by ESU Services – a sustainability consulting firm and commissioned by the Swiss Gas and Water Association (SVGW) in 2014.

The Oxfam briefing Feeding Climate Change: what the Paris Agreement Means for Food & Beverage Companies looks at commodities and climate change and policy from the perspective of the food and beverage industry.

Nanotechnology – the designing of ultra-small particles – is part of the evolving science of precision agriculture, and could potentially solve some of the world’s most pressing problems at the food-energy-water nexus as it requires fewer natural resources and water, and enhances plant nutritional values.
