“…The degree to which a C2C product’s designated attributes may be quantified by an LCA depends on the measurement’s percentage. In other words, how detailed can the attributes be stated, rather than merely conceptually [ 69 ]. However, if a future scenario has been decided upon, an LCA can be used to evaluate future technology.…”

Over the last several years, the number of concepts and technologies enabling the production of environmentally friendly products (including materials, consumables, and services) has expanded. One of these ways is cradle-to-cradle (C2C) certifiedTM. Life cycle assessment (LCA) technique is used to highlight the advantages of C2C and recycling as a method for reducing plastic pollution and fossil depletion by indicating the research limitations and gaps from an environmental perspective. Also, it estimates the resources requirements and focuses on sound products and processes. The C2C life cycle measurements for petroleum-based poly (ethylene terephthalate) (PET) bottles, with an emphasis on different end-of-life options for recycling, were taken for mainland China, in brief. It is considered that the product is manufactured through the extraction of crude oil into ethylene glycol and terephthalic acid. The CML analysis method was used in the LCIA for the selected midpoint impact categories. LCA of the product has shown a drastic aftermath in terms of environmental impacts and energy use. But the estimation of these consequences is always dependent on the system and boundary conditions that were evaluated throughout the study. The impacts that burden the environment are with the extraction of raw material, resin, and final product production. Minor influences occurred due to the waste recycling process. This suggests that waste degradation is the key process to reduce the environmental impacts of the production systems. Lowering a product’s environmental impact can be accomplished in a number of ways, including reducing the amount of materials used or choosing materials with a minimal environmental impact during manufacture processes.

“…Çevresel ayak izleri, bir ürün veya hizmetin çevresel etkisini tanımlamaktadır. Karbon ayak izi, su ayak izi, azot ayak izi ve enerji ayak izi göstergelerinin tümü çevresel ayak izi olarak adlandırılmaktadır (Karwacka vd., 2020;Matuštík & Kočí, 2021). Karbon ayak izi, iklim değişikliğine artan ilgiyle bağlantılı olarak 1960'larda ortaya çıkmış (Karwacka vd., 2020), bilimsel tanımı 2006 yılında yapılmış (Chen vd., 2021) ve son zamanlarda muazzam bir popülerlik kazanmıştır (Weidema vd., 2008).…”

The fact that greenhouse gas emissions have greatly increased over the years with rapid industrialization and that carbon dioxide has the highest rate among these gases has revealed that carbon footprint is not a fashionable concept but a reality. Carbon footprint is the total amount of carbon dioxide (CO2) emissions caused directly or indirectly by an activity or accumulated during the life cycle of a product, and this concept is used in many industries to determine carbon emissions. Logistics and transportation are among the sectors producing the most CO2 in the world. The aim of this study is to provide a conceptual framework for the structure, limits and development trend of the carbon footprint in logistics and transportation through a comprehensive and systematic literature review. Systematic literature studies are carried out by considering one or more databases, and in this study, articles in the Web of Science (WoS) database are used. Within the scope of the study, 373 articles were reached as a result of the first search from the WoS database, and as a result of the examination of the inclusion and exclusion criteria of this study, title, abstract and keywords, 24 studies were included in the sample. As a result of the studies examined, the subject of logistics and transportation carbon footprint has been studied since 2010, most of the studies have been published in developed countries, quantitative methods are preferred more in studies and mainly trying to calculate the carbon footprint by developing case studies, models or methods, since the subject is new and its costs are relatively high, the application part of the carbon footprint could not be fully formed in the sector, there is a limited number of studies on the carbon footprint of international logistics and transportation and the carbon footprint of sustainable logistics and transportation in developing countries, it has been found that there are no studies examining the social effects of logistics and transportation carbon footprints. This study will systematically give an idea about the current knowledge and findings produced in the research field and serve as a guide for future research.

“…WFA and LCA share a generic framework: setting goals and scope; accounting phase; impact assessment phase and interpretation [97]. WFA and LCA serve different goals, as life cycle assessment is a product-focused method, aiming to achieve sustainability of products, while water footprint assessment is a water management approach with a focus on the sustainability of water resources [97,98]. Water footprint assessment was developed with a focus on agricultural sectors and food production processes [79] at its early stage, then extended to industrial sectors, with currently focusing on agricultural and forestry-based production (such as paper, dairy and textile) and energy production (such as bioenergy and electricity) [99], whereas LCA had its starting point with a focus on industrial products and sectors.…”

“…The WFA community measures blue, green and grey water footprints, but LCA only includes the blue water footprint [97]. The LCA community argues that only net green water (the difference between cropland and natural vegetation) should be counted [98], but it would lead to net negative green water footprints, because evapotranspiration of natural vegetation might be larger than that of croplands [98].Thus, it is unusual to account for green water footprints in LCA. The other issue is with regard to grey water footprint accounting, as the LCA community argues that different indicators such as acidification, eutrophication or toxicity potential are better suited to measure water pollution [79].…”

Production and consumption activities deplete freshwater, generate water pollution and may further lead to water stress. The accurate measurement of water stress is a precondition for sustainable water management. This paper reviews the literature on physical water stress induced by blue and green water use and by water pollution. Specifically, we clarify several key concepts (i.e., water stress, scarcity, availability, withdrawal, consumption and the water footprint) for water stress evaluation, and review physical water stress indicators in terms of quantity and quality. Furthermore, we identify research gaps in physical water stress assessment, related to environmental flow requirements, return flows, outsourcing of water pollution and standardization of terminology and approaches. These research gaps can serve as venues for further research dealing with the evaluation and reduction of water stress.
