Global impacts of energy demand on the freshwater resources of nations

CIE-MAP researcher Kate Scott published a paper in PNAS on understanding the roles of energy production and international trade in driving pressures on (often scarce) freshwater resources. The authors coupled a trade and hydrological model to examine pressures on freshwater resources associated with energy production across the global economy. While the electric and gas sectors induce freshwater consumption predominantly within countries where demand originates (91% and 81%, respectively), the petroleum sector exhibits a high international footprint (56%). The analysis demonstrates the importance of broadening the discourse on energy policy from greenhouse gas emissions to address issues including freshwater scarcity, the role of international trade, and wider environmental and societal considerations.

Construction sector views on low carbon building materials

A new research paper written by Jannik Giesekam and John Barrett has been published in the October 2015 edition of Building Research and Information. The paper is titled ‘Construction sector views on low carbon building materials‘.

As is the case in a number of countries, the UK construction industry faces the challenge of expanding production whilst making ambitious greenhouse gas emission reductions. Embodied carbon constitutes a growing proportion of whole-life carbon emissions and accounts for a significant share of total UK emissions. A key mitigation strategy is increasing the use of alternative materials with lower embodied carbon. The economic, technical, practical and cultural barriers to the uptake of these alternatives are explored through a survey of construction professionals and interviews with industry leaders. Perceptions of high cost, ineffective allocation of responsibility, industry culture, and the poor availability of product and building-level carbon data and benchmarks constitute significant barriers. Opportunities to overcome these barriers include earlier engagement of professionals along the supply chain, effective use of whole-life costing, and changes to contract and tender documents. A mounting business case exists for addressing embodied carbon, but has yet to be effectively disseminated. In the meantime, the moral convictions of individual clients and practitioners have driven early progress. However, this research underscores the need for new regulatory drivers to complement changing attitudes if embodied carbon is to be established as a mainstream construction industry concern.


Sarah Turner: Eco-Artist and designer through craft-based upcycling

A new research paper written by Kyungeun Sung and Tim Cooper has been published in the March 2015 edition of Craft Research. The article is titled Sarah Turner-Eco Artist And Designer Through Craft Based Upcycling

Abstract: Sarah Turner is an eco-artist and designer who practices craft-based upcycling with waste plastic bottles and cans to create lighting, sculpture and decorative home interior products. Since 1998, her enthusiasm, creativity and good will have allowed her to gain several high-profile client commissions and to win awards from design, innovation and business competitions. The aim of this portrait is to introduce Sarah’s work and shed light on the resources, knowledge and skills involved in her practice and on the barriers to and drivers for her craft-based upcycling. We consider that Sarah’s work could be one of the stepping stones for a shift towards more sustainable craft practice, both in the United Kingdom and beyond. By exploring the right ingredients for craft-based upcycling, barriers liable to be faced and key drivers that stimulate motivation, we hope that this portrait will inspire and attract more designers and makers to embed upcycling in their future practice.

Jonathan Norman co-authors study on UK steel demand

Jonathan Norman was co-author of a study on Options to supply the UK steel demand and meet the CO2 targets presented by André Cabrera Serrenho of the University of Cambridge at the International Society of Industrial Ecology’s 2015 Conference. The work examined how different methods of steel production in the UK would combine with national energy pathways and effect future production and consumption emissions associated with steel. A journal article on this work is currently under review.
