The purpose of this report is an in-depth environmental impacts study of the production of polyethylene from Brazilian sugarcane-based bioethanol using actual supply chain and production process data to augment an earlier theoretical study. E4tech performed a life cycle assessment looking at global warming potential, abiotic depletion potential, acidification potential, eutrophication potential, human toxicity potential and ecotoxicity; an analysis of the indirect land-use impacts of using sugarcane to produce chemicals; and a water footprint study focusing on the sustainability of the local water usage.

Switzerland has set ambitious efficiency targets to help it meet its 2050 energy goals. The objective of the report is to investigate if these could be endangered by potential efficiency losses due to the implementation of flexible demand-side management (DSM). E4tech reviewed commercial and industrial DSM potential in Switzerland and applied a multi-criteria ranking to identify representative examples for detailed case studies. We then interviewed industry experts and analysed operation patterns for three applications: cement mills, deep-freeze warehouses, and waste-water treatment plants, looking at the expected impacts on efficiency. The final report contains application-specific recommendations and an informed discussion of the trade-offs between demand-side management and energy efficiency, to help the client in tailoring its funding policy.
In 2013 a consortium of six automotive and fuel companies commissioned E4tech to assess the potential contribution of biofuels to European road transport to 2030 – and to identify a coherent industrial and policy framework that would enable sustainable biofuels to effectively contribute to the decarbonisation of road transport. Our report shows that a window of opportunity exists to find a constructive way forward to help meet EU policy objectives, to send clearer investments signals to industry and to identify options for more coherent sustainable transport policies aimed at automotive and fuel industries.
