Sustainability in the Aerospace Sector, a Transition to Clean Energy: The E2-EVM Valuation Model. Sustainability 2021, 13, 6717. https://doi.org/10.3390/su131267172071-1050https://hdl.handle.net/10115/30590Civil aviation is one of biggest industrial contributors to CO2 emissions worldwide. One of the most urgent problems of this sector is providing new technologies to continue operating in a more sustainable environment through a transition to clean energy. The Earned Value Management (EVM) model, as a traditional project management tool, is continuously being revised with new releases and extensions (e.g., ESM, EDM, QEVM, E-EVM, and ZEVM), but to date none of them has applied an expert judgment criterion to be able to modify and anticipate the final result of the project. In such a way, this paper introduces a novel approach to the topic with the so-called Enhanced and Efficient Earned Value Management (denoted E2-EVM) model by including this new capability through the real options methodology, thus helping to support the sustainability of the aerospace sector. This research focuses on three main goals: the description of recent green initiatives in the aerospace sector by checking its contribution to reaching the well-known Sustainable Development Goals (SDGs), the development of a new version of the EVM model by applying the real options methodology, and, finally, the financial contribution to the aerospace industry by applying these initiatives and methodologies.engAtribución 4.0 Internacionalhttp://creativecommons.org/licenses/by/4.0/sustainable development goalsaerospace industryearned value managementreal optionsinfo:eu-repo/semantics/article10.3390/su13126717info:eu-repo/semantics/openAccess
