“…Refrigerant has become better in efficiency, with a lower environmental impact, but needs more improvement. The currently popular hydrofluorocarbon adopted for ozone layer protection has large global warming potential (GWP) [43,44]. Thus, new refrigerant is required that is more energy efficient and has a lower GWP.…”

In recent years, sustainable supply chain management has gained increasing attention, and greenhouse gas (GHG) emissions throughout supply chains have been identified as one of the most important sustainability issues. This paper presents an investigation of the problem of transshipment among distribution centers (DCs) in a cold supply chain to achieve sustainable inventory cross-filling. Although transshipment is an effective tool for supply chain pooling, the possibility of increased GHG emissions raises environmental concerns. This study establishes a sustainable cold-chain logistics model that considers GHG emissions from DC storage and transshipment trucks. The new sustainable cold-chain model also reflects laden status and cargo weights of trucks for accurate emission assessment. An optimization model is also developed to minimize both GHG emissions and costs in the cold chain. Numerical simulations are conducted for diverse problem cases to examine important problem characteristics. The result analysis identifies that inventory service levels and demand variability have a strong impact on GHG emissions in transshipment; small p-values in the statistical analysis verify the significance of this effect. The different effects of demand variability and service levels on each emission source are also analyzed. The results demonstrate that transshipment among DCs can effectively reduce both GHG emissions and costs in cold supply chains. This study provides useful models and tools to assess GHG emissions and optimize decisions for the design and operation of transshipment. The proposed models will enable the assessment of sustainable alternatives and achieve sustainability objectives effectively for cold supply chains.

“…The analysis of global warming potential quantifies the contribution of greenhouse gases to climate change, encompassing various activities such as energy consumption for maintaining optimal microclimatic conditions, energy use linked to resource consumption, and waste and emissions management from specific agricultural practices [192]. This metric plays a key role in conducting a comprehensive environmental assessment of indoor agricultural production [193].…”

“…This phenomenon is associated with the presence of halocarbons, which are compounds that break down ozone molecules and contribute to ozone layer depletion. The consequences include increased radiation, including ultraviolet radiation, reaching the Earth's surface, potentially leading to various climatic alterations with implications for ecosystems and human health [193].…”

Researchers and practitioners use life cycle assessment (LCA) as a powerful tool to thoroughly assess the environmental impact of protected agriculture. However, the literature in this field has shown heterogeneity, which is characterized by inconsistent methodologies and assumptions. Identifying prevailing trends and resolving existing limitations is necessary to generate robust results and guide future work. Here, we conduct a bibliometric and systematic review to explore how LCA applications have addressed protected agriculture. The bibliometric analysis unveils trends in scientific productivity, spanning temporal evolution and geographic distribution, while also identifying prominent research avenues. The systematic review traces the historical trajectory of agricultural LCA and scrutinizes methodological decisions across the standard LCA phases: (i) objective and scope, (ii) life cycle inventory, (iii) impact assessment, and (iv) interpretation. We summarize and discuss the reported environmentally friendly practices and provide a qualitative interpretation of the LCA findings. Moreover, we pinpoint key methodological challenges and propose research horizons. It is crucial to note that the environmental benefits of protected agriculture are context-dependent, with climate change emerging as a critical factor influencing crop yields and the system’s input and output resources. This impact is particularly pronounced in terms of water and energy consumption and carbon emissions. In regions with extreme climates, protected agriculture provides solutions for producers aiming to attain high yields of top-quality crops. The integration of circular bioeconomy strategies in this context allows mitigation of the environmental trade-offs identified by LCA.

“…However, upon release to the upper layers of the atmosphere, CFCs evolve chlorine radicals from C–Cl breakup under the impact of photocatalysis and lead to ozone transformation toward oxygen. CFCs have a high ozone-depleting potential (ODP), a parameter evaluated by the ratio of ozone loss after discharging a chemical to the same mass of trichlorofluoromethane (R11) (R11 ODP is referred to as 1.0) . For example, the ODPs of CFCl 3 , CCl 2 F 2 , CBrClF 2 , and CBrF 3 are 1, 1, 7.1, and 16, respectively.…”

The energy demand for traditional vapor-compressed technology for space cooling continues to soar year after year due to global warming and the increasing human population's need to improve living and working conditions. Thus, there is a growing demand for eco-friendly technologies that use sustainable or waste energy resources. This review discusses the properties of various refrigerants used for adsorption cooling applications followed by a brief discussion on the thermodynamic cycle. Next, sorbents traditionally used for cooling are reviewed to emphasize the need for advanced capture materials with superior properties to improve refrigerant sorption. The remainder of the review focus on studies using engineered nanoporous frameworks (ENFs) with various refrigerants for adsorption cooling applications. The effects of the various factors that play a role in ENF−refrigerant pair selection, including pore structure/ dimension/shape, morphology, open-metal sites, pore chemistry and possible presence of defects, are reviewed. Next, in-depth insights into the sorbent−refrigerant interaction, and pore filling mechanism gained through a combination of characterization techniques and computational modeling are discussed. Finally, we outline the challenges and opportunities related to using ENFs for adsorption cooling applications and provide our views on the future of this technology.
