Consequential Life Cycle Assessment evaluates the consequences of this selection and provides environmental data to support decision-making. This research uses a consequential approach to assess the environmental impacts of two medium power generation systems. The selected environmental impact assessment methods are IPCC 2013 GWP 100y and ReCiPe 2016. Moreover, the work describes a methodology for finding the marginal mix technologies for electricity and cooling energy production depending on the time horizon. The positive environmental consequences associated with short-term marginal energy mixes (electricity and cooling) progressively disappear when the marginal energy mix varies throughout time. The environmental results strongly depend on the marginal mix of technologies and evidence the necessity to develop methodologies and standards to improve the robustness of environmental assessments. A new line of discussion is opened concerning the temporal variation of environmental impacts of an energy production system, which could also be considered in Attributional Life Cycle Assessments. info:eu-repo/grantAgreement/ES/DGA/T55-20R info:eu-repo/grantAgreement/ES/MICINN/RYC2021-034265-I info:eu-repo/grantAgreement/ES/MINECO-PID2020-115500RB-I00 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 10.9 2023 ENVIRONMENTAL STUDIES 7 / 182 = 0.038 2023 Q1 T1 GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY 7 / 91 = 0.077 2023 Q1 T1 GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY 7 / 91 = 0.077 2023 Q1 T1 2.359 2023 Environmental Chemistry 2023 Q1 Renewable Energy, Sustainability and the Environment 2023 Q1 Industrial and Manufacturing Engineering 2023 Q1 Environmental Engineering 2023 Q1 17.4 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Abrahão, Raphael Carvalho, Monica 5004 590 Universidad de Zaragoza Dpto.
