Developing Low Carbon Supply Networks: Influence, Measurement, and Improvement
… dilemma between fast industrial development and carbon reduction makes firms in developing nations reluctant to take serious commitment and actions in CO2 emission reduction in their global manufacturing practices. From a theoretical perspective, low-carbon supply networks research is also still …

Low-carbon transformation of the German and European electricity systems
This dissertation addresses the low-carbon transformation of the German and European electricity sectors. It applies techno-economic electricity sector models to research questions on market design and infrastructure investment. The first part consists of three chapters on Germany. It starts with a …

Reading the future : constructing low-carbon imaginaries in urban institutions
… to play a central role in transitions towards a low carbon economy and society (Coenen, Benneworth & Truffer, 2012; Goddard & Vallance, 2013). However, the nature of institutions both enables and militates against sociotechnical change, constraining the futures that are imaginable and achievable. …

The strengthening and "softening" of low-carbon structural steels by silicon
… adding silicon, up to 1.03 wt% in five grades of low carbon structural steel was studied. The reduced sensitivity of the lower yield stress, σy, at sub-zero test temperatures, otherwise called "softening", of these steels with reduced grain sizes, brought about by the silicon additions was also …

Financial incentives for low-carbon transition: from citizens to professional investors
Decarbonisation of the global economy requires an energy transition of exceptional scope, depth and speed, and a doubling of the current level of investment in low-carbon technologies. However, the risk perception of individual market participants—a key determinant of the pace at which these …
