“…Through LCA, Geller et al [53] compared uncertainty factors such as different energy sources and several hydropower plants with differing characteristics. Lima et al [1] critically reviewed the relationship between uncertainty analysis and life cycle assessment in 64 scientific publications addressing the biorefineries' systems. Bamber et al [13] conducted a review study to determine and assess the reported frequency of uncertainty in LCA studies (including attributional and consequential LCA and any combinations of these two).…”

“…In the new economic context that has emerged in recent years, the environmental impact of products and services has become a vital concern. To measure and assess these impacts, several tools and frameworks can be utilized, such as life cycle assessment (LCA), environmental impact assessment (EIA), environmental risk assessment (ERA), material flow analysis (MFA), strategic environmental assessment (SEA), cost-benefit analysis (CBA), and the ecological footprint (EF) method [1]. LCA is one of the most well-known approaches [2].…”

Today, life cycle assessment (LCA) is the most widely used approach to model and calculate the environmental impacts of products and processes. The results of LCAs are often said to be deterministic, even though the real-life applications are uncertain and vague. The uncertainty, which may be simply ignored, is one of the key factors influencing the reliability of LCA outcomes. Numerous sources of uncertainty in LCA are classified in various ways, such as parameter and model uncertainty, choices, spatial variability, temporal variability, variability between sources and objects, etc. Through a scoping review, the present study aims to identify and assess the frequency with which LCA studies reflect the uncertainty and what are the tools to cope with the uncertainty to map the knowledge gaps in the field to reveal the challenges and opportunities to have a robust LCA model. It is also investigated which database, methodology, software, etc., have been used in the life cycle assessment process. The results indicate that the most significant sources of uncertainty were in the model and process parameters, data variability, and the use of different methodologies and databases. The probabilistic approach or stochastic modeling, using numerical methods such as Monte Carlo simulation, was the dominating tool to cope with the uncertainty. There were four dominant LCA methodologies: CML, ReCiPe, IMPACT 2002+, and TRACI. The most commonly used LCA software and databases were SimaPro® and Ecoinvent®, respectively.

Increased lightning intensity generally causes an increase in the level of hazards such as infrastructure damage and death. To mitigate these hazards, research is necessary. Research developments can be seen from the various literature published in journals or books. This study aimed to quantitatively assess the development of research on lightning protection, grounding systems, and soil resistivity. The bibliometric method is used by searching based on keywords in the Scopus basis data, then visualizing it using VOSviewer. The results showed that the total identified publications were 706 publications all years, the first publication in 1967 and the highest in 2014-2020 with 481 publications (68.1%). The countries that dominate are China and Brazil. Universidade Federal de Minas Gerais was the most productive institution, while Silverio Visacro was the most productive writer. Engineering and energy are the most widely written subjects, while topics related to multidisciplinary are still rare (0.2%). Electric Power Systems Research Journal is the top journal that publishes this research topic. The publication progress map based on co-occurrences consists of 9 clusters. The few research topics include electrical safety, substation, and backfill materials, while current topics include towers, wind turbines, bentonite, natural enhancement materials, and electromagnetic models. ABSTRAKPeningkatan intensitas petir umumnya menyebabkan peningkatan level bahaya seperti kerusakan infrastruktur dan kematian. Untuk memitigasi bahaya tersebut, perlu dilakukan riset. Perkembangan riset dapat dilihat dari berbagai literatur yang diterbitkan pada jurnal atau buku. Studi ini bertujuan untuk menilai secara kuantitatif perkembangan riset tentang proteksi petir, sistem pentanahan dan resistivitas tanah. Metode yang digunakan yaitu metode bibliometrik dengan melakukan penelusuran berdasarkan kata kunci pada basis data Scopus, kemudian divisualisasi menggunakan VOSviewer.

In this article, we discuss the uncertainties involved in the models and in the measurements necessary to estimate the emissions of greenhouse gases (GHG) in a chemical industry. When these uncertainties cannot be neglected and some measurements exhibit correlations with others, estimating the final emission is not a trivial task. Even if we intend to determine a simple point estimate for the mean emissions, we will need to use the average values of the measurements as well as information about their uncertainties and correlations in complex computations. To solve this problem, we propose a Monte Carlo method to estimate the mean and confidence interval of CO2 emissions in the context of uncertainties and correlations. We validated our approach through a case study involving a traditional chemical company in Brazil. Our results indicated that previously, there was an overestimation of the emission because the company did not consider uncertainties and correlations. The overestimation was modest since the parameters involved present relatively little uncertainty, but the bias effect was clear. This research has demonstrated the importance of accounting for uncertainties and correlations in emission estimates, providing a practical framework for analyses in industrial settings.
