Race to burn the last ton of carbon and the risk of stranded assets

A cap on global warming implies a tighter carbon budget which can be enforced with a credible second-best renewable energy subsidy designed to lock up fossil fuel and curb cumulative emissions. Such a subsidy brings forward the end of the fossil fuel era but accelerates fossil fuel extraction and global warming in the short run. A weaker fossil fuel oligopoly implies that anticipation of a given global carbon budget induces fossil producers to deplete reserves more voraciously and accelerate global warming. This race to burn the last ton of carbon is more intensive for the feedback than open-loop Nash equilibrium, so that the Green Paradox effect of a renewable energy subsidy is stronger. There is an intermediate phase of limit pricing to keep renewable energy producers at bay, which becomes much more relevant when a cap on global warming is enforced. A stronger fossil fuel oligopoly lengthens the period of limit pricing and typically brings forward the carbon-free era. Finally, the mere risk of a cap on global warming being enforced at some unknown, future date makes fossil fuel extraction more voracious and accelerates global warming.

Service Science Management Engineering and Design (SSMED): a semiautomatic literature review

ABSTRACT

SSMED (Service Science, Management Engineering and Design) is multidisciplinary by nature. However, some authors stated that SSMED publications remain focused on single scientific domains. This paper proposes a Semiautomatic Literature Review (SALR) using integrated techniques for knowledge extraction –‘Time Aware Knowledge Extraction’ (TAKE) – to analyse the interdisciplinarity of SSMED publications and the potential for transdisciplinarity based on the actual adoption of Service-Dominant Logic as the foundation of SSMED research. Findings reveal that: 1) most SSMED publications are not interdisciplinary and are mainly related to Management; 2) Service-Dominant Logic has been adopted very often in SSMED publications, paving the way for SSMED transdisciplinarity.

This paper offers theoretical and practical insights by enhancing the knowledge about SSMED literature and enriching the state of the art related to techniques to perform literature reviews. Furthermore, it stimulates the expansion of scholars’ and managers’ views of holistic approaches to service systems while fostering SSMED viability.
