Seminários de ciclo de vida

Os Seminários de Ciclo de Vida são sessões em que investigadores (tanto do CIE como oradores convidados) apresentam e discutem temas relacionados com a Avaliação e Gestão do Ciclo de Vida, no âmbito de projetos/teses em curso. Geralmente ocorrem antes do almoço do grupo CIE, às quartas-feiras, e duram aproximadamente 45 minutos (20-30 min de apresentação 15-20 min de discussão). O objetivo destes seminários é partilhar e ampliar o conhecimento sobre ACV e tópicos relacionados, bem como criar sinergias entre investigadores do CIE e outras organizações.

Se estiver interessado em participar num dos nossos próximos seminários, envie-nos um email.

“Robust decision making in vehicle LCA, the need for uncertainty propagation”, por Maarten Messagie.

The aim of this lecture is to give insights in how to bring uncertainty propagation in LCA. One of the main shortcomings in literature on vehicle LCA is the lack of incorporating uncertainties. In most studies, environmental impacts are shown with single values. The complexity, uncertainty and variability of the system are not well approximated with single values. Single values approximate the environmental impact of a vehicle, but fail to provide a wider view on the possible effects. Uncertainties are an inherent part of LCA and should not be avoided but embraced and made explicit in the result. Identifying and integrating uncertainties in the result gives a more robust interpretation. Many sources of uncertainty exist in LCA, two distinct classes of uncertainties are discussed, namely parameter uncertainty and modeling uncertainty.

Firstly, parameter uncertainty deals with the variability of the car market, the mismatches between the theoretic values derived from the New European Driving Cycle (NEDC) compared to the real life driving conditions and the unrepresentativity and inaccuracy of the background data (data from general databases). The most spectacular differences between the NEDC and the real-life values concern the emissions of NOx and CO. However, the contribution of the market variability to the overall uncertainty is larger compared with the uncertainties due to differences in driving cycle. The influence of the uncertainties on the result is made explicit by adding error bars in the LCA graphs.

Secondly, modeling uncertainty deals with the uncertainty in life cycle impact assessment due to normalization, weighting and methodology. The choice of the Life Cycle Impact Assessment method itself introduces an uncertainty. The different vehicle technologies are compared using EDIP, Eco-Indicator 99, EPS and Impact 2002 to calculate the environmental performance. As the impact methods have different viewpoints on environmental impact a large difference in ranking is observed.

“SALCA – Swiss Agricultural Life Cycle Assessment”, por Carolina Passeira.

Agricultural systems have become a focus in the last three decades, not only because of their obvious importance in humans’ life but also because of their contributions for global warming (about 12% of the total emissions, according to the IPCC). For that reason, stakeholders saw an opportunity to create a generic tool to assess and improve agriculture’s environmental impacts. From a strong connection between Agroscope, Ecoinvent and several stakeholders in food production, food and energy industry, government and consumers, SALCA was shaped. This user friendly generic tool was already used for many studies, in many points of Europe, and it has proven its value and consistency.

“The Environmental Impact of Internet-Based Services”, por Vlad Coroama.

Information and Communication Technologies (ICT) are increasingly seen as important contributors towards societal dematerialization, through the substitution of ICT-based services for less efficient processes and activities. Such claims, however, seldomly go beyond mere visions, as the substitutes’ own environmental impacts are poorly understood. While numerous assessments of the energy consumption and carbon intensity of ICT equipment were put forward, they typically only pay attention to the use-phase of the equipment, ignoring the rest of the life cycle. Moreover, existing studies focus on ICT equipment and largely ignore the services it enables, which are the ones actually inducing dematerialization. The talk focuses on these gaps and presents some recent, LCA-based studies of the environmental impact of Internet-based services.

About Vlad Coroama: A computer scientist by education, Vlad's research focuses on the environmental impact assessment of the Internet, its services, and their dematerialization potential. He is both a skeptic about his own field, and a firm believer in Dave MacKay's "1% rule" that states that, when it comes to sustainability, the societal and academic discussion should focus on the big numbers, and not on peanuts.

An assessment of the cultivation area needed for the substitution of 10% of diesel consumed in the transportation sector for biodiesel was also performed.

“Environmental Life Cycle Assessment of Conventional and Electric Vehicles", por Pedro Marques

This paper aims at presenting a comparative life-cycle assessment of conventional (diesel and gasoline) and electric (BEV and PHEV) vehicles. Five environmental impact categories have been analyzed (abiotic depletion, acidification, eutrophication, global warming and ozone layer depletion), using the CML 2000 method. The results show that the electricity mix scenario is a determining factor in the choice of the technology with the least environmental impacts for four of the five categories analyzed (abiotic depletion, acidification, eutrophication and global warming).

“Energetic and Environmental Assessment of the demilitarization of military munitions in static kiln", por Carlos Ferreira

Nowadays organizations face growing environmental constraints, particularly in the form of legal requirements, and the defense sector is no exception.
