“…Larger magnitudes of each parameter are indicative of environmentally preferable performance, and values equal to one indicate processes that are energy or net GHG emissions neutral. Increasing use of self-normalized metrics such as EROI or NGR over time has increased the utility of algae LCA data [36]. From Table 2, all three case study systems mediate net GHG sequestration, but only one (OPS) is net energy producing.…”

“…Recent years have seen increasing interest in life cycle greenhouse gas emissions accounting, also called carbon footprinting. There are several drivers for this increased interest, such as life cycle emissions accounting for transportation fuels policy (Crane and Prusnek 2007) and an increasing interest in climate‐related eco‐labels (Horne 2009; Lim and Park 2009). These “carbon labels” are a specific form of environmental product declaration (standardized by ISO 14025 [ISO 2006a]) and have been studied or implemented in the United Kingdom, Japan, and California, and among large retailers such as Walmart and Tesco (Bolwig and Gibbon 2009).…”

Summary Recent years have seen increasing interest in life cycle greenhouse gas emissions accounting, also known as carbon footprinting, due to drivers such as transportation fuels policy and climate‐related eco‐labels, sometimes called carbon labels. However, it remains unclear whether applications of greenhouse gas accounting, such as carbon labels, are supportable given the level of precision that is possible with current methodology and data. The goal of this work is to further the understanding of quantitative uncertainty assessment in carbon footprinting through a case study of a rackmount electronic server. Production phase uncertainty was found to be moderate (±15%), though with a high likelihood of being significantly underestimated given the limitations in available data for assessing uncertainty associated with temporal variability and technological specificity. Individual components or subassemblies showed varying levels of uncertainty due to differences in parameter uncertainty (i.e., agreement between data sets) and variability between production or use regions. The use phase displayed a considerably higher uncertainty (±50%) than production due to uncertainty in the useful lifetime of the server, variability in electricity mixes in different market regions, and use profile uncertainty. Overall model uncertainty was found to be ±35% for the whole life cycle, a substantial amount given that the method is already being used to set policy and make comparative environmental product declarations. Future work should continue to combine the increasing volume of available data to ensure consistency and maximize the credibility of the methods of life cycle assessment (LCA) and carbon footprinting. However, for some energy‐using products it may make more sense to increase focus on energy efficiency and use phase emissions reductions rather than attempting to quantify and reduce the uncertainty of the relatively small production phase.

“…U prilog navedenom, autori Lozano, Blanco i Rey-Maquieira [7] navode da eko oznake predstavljaju jedno od sredstava koje olakšava sertifikaciju strategije očuvanja životne sredine. Analiza [8] prikazuje da eko oznaka ima potencijal da potpuno zameni druge inicijative životne sredine koje ne predviñaju sertifikaciju. Eko oznake pomažu organizacijama da identifikuju proizvode i usluge koji imaju smanjen uticaj na životnu sredinu, razmatrajući njihov celokupan životni ciklus (od ekstrakcije sirovina, preko proizvodnje, korišćenja, i, konačno, odlaganja).…”
