Several water footprint indicators have been developed to curb freshwater stress. Volumetric footprints support allocation decisions and strive increase productivity in all sectors. In contrast, impact-oriented are used minimize the impacts of use on human health, ecosystems, resources. Efforts combine both perspectives a harmonized framework undertaken, but common challenges remain, such as pollution ecosystems modelling. To address these knowledge gaps, we build upon assessment proposed at...
The aviation sector contributes to environmental problems like climate change, resource depletion, and air pollution. We perform a systematic literature review of life cycle assessment studies map the impacts in provide methodological recommendations. is divided into cross-cutting systems, namely aircraft, fuel propulsion airports. Our results confirm sector's focus on change impacts. mitigation strategies rely mostly reducing CO2 emissions during aircraft operations, implementing...
The aviation sector needs to reduce its environmental impacts, like climate change and air pollution. New hybrid-electric aircraft concepts may contribute abating part of these impacts. But what extent under which conditions? This study addresses questions in the context regional identifies technologies concrete actions required for more environmentally sustainable aviation. impacts emerging configurations deployed 2030, 2040, 2050 have been comprehensively quantified using prospective life...
Reduced river discharge and flow regulation are significant threats to freshwater biodiversity. An accurate representation of potential damage water consumption on biodiversity is required quantify compare the environmental impacts global value chains. The effect reduction fish species richness was previously modeled in life cycle impact assessment, but models were limited by restricted geographical scope underlying species-discharge relationships small number data. Here, we propose a model...
Balancing human communities' and ecosystems' need for freshwater is one of the major challenges 21
Hybrid-electric aircraft represent a promising solution for the urgent need to decarbonize short-haul flights and bolster aviation sustainability. Nevertheless, realization of hybrid-electric demands rigorous environmental impact analysis, given substantial investments, time, research required technology development. This study offers comprehensive life cycle inventory spanning years 2030, 2040, 2050 both conventional configurations. Our datasets are meticulously constructed through...
The aeronautics sector has been regarded as an important contributor to environmental problems, due aircraft fuel consumption and combustion emissions. Little is known about the other parts of value chain, in particular manufacturing. complexity systems lack public data have prevented analysis disaggregated contributions chain key problems - that could provide valuable insight reduce impacts. We addressed this knowledge gap by developing a new mapping method quantify burden manufacturing...
Hybrid-electric aircraft are often perceived as a potential solution to decarbonize short-haul flights and enhance aviation sustainability. However, making hybrid-electric reality should be backed by robust environmental impact analysis because the necessary technology development is investment, time, research-heavy. In this study, we thus developed total of 45 prospective life cycle inventories (LCI) for conventional hybrid electric configurations technologies 2030, 2040, 2050. The LCI...
Increasing demand for air transport has compelled airports to control resource consumption. The circular economy concept can help, although its systematic implementation and potential benefits are still unclear. Here, we propose a framework tackle this challenge. First, categorize the activities airports. Then define 17 indicators gauge use covering solid waste management, energy consumption, shared means of transport, water quality Finally, quantified compared "reference points", which...
