    Abstract: The requirement of social distancing during the COVID‐19 pandemic has presented significant challenges for high‐rise buildings, which heavily rely on elevators for vertical transportation. In particular, the need for social distancing has reduced elevator capacity typically by at least two‐thirds or as much as over of the normal amount. This reduction is a serious concern, as reduced elevator capacities cause large queues to build up in lobbies, which makes social distancing difficult and results in large wait times. The objective of this study is to safely manage the elevator queues by proposing simple, technology‐free interventions that drastically reduce the waiting time and length of lobby queues. We use mathematical modeling, epidemiological expertise, and simulation to design and evaluate our interventions. The key idea is to explicitly or implicitly group passengers that are going to the same floor into the same elevator as much as possible. In the Cohorting intervention, we attempt to find passengers going to the same floor as the first person in the queue. In the Queue Splitting intervention, we create a different queue for different groups of floors. Based on simulation and analytical findings, Cohorting and Queue Splitting can significantly reduce queue length and wait time, while also maintaining safety from viral transmission in otherwise crowded elevators, building lobbies, and entrances. These interventions are generally accessible for many buildings since they do not require programming the elevators, and rely on only using signage and/or a queue manager to guide passengers.

    Abstract: We conduct a multidisciplinary systematic literature review on climate neutrality in the supply chain. While carbon neutrality has gained prominence, our study argues that achieving carbon neutrality alone is not enough to address climate change effectively, as non-CO 2 greenhouse gases (GHG) are potent contributors to global warming. Design/methodology/approach We used multiple databases, including EBSCO, ProQuest, Science Direct, Emerald and Google Scholar, to identify articles related to climate neutrality in the context of non-CO 2 gases. A total of 71 articles in environmental science, climate change, energy systems, agriculture and logistics are reviewed to provide insights into the climate neutrality of supply chains. Findings We find that, in addition to CO 2 , other GHG such as methane, nitrous oxide, ozone and fluorinated gases also significantly contribute to climate change. Our literature review identified several key pillars for achieving net-zero GHG emissions, including end-use efficiency and electrification, clean electricity supply, clean fuel supply, “GHG capture, storage and utilization,” enhanced land sinks, reduced non-CO 2 emissions and improved feed and manure management. Originality/value We contribute to the literature on climate neutrality of supply chains by emphasizing the significance of non-CO 2 GHG along with CO 2 and highlighting the need for a comprehensive approach to climate neutrality in addressing climate change. This study advances the understanding of climate neutrality of supply chains and contributes to the discourse on effective climate change mitigation strategies. It provides clear future research directions.

    Abstract: COVID‐19 has disrupted the lives of millions of people worldwide. Migrants in developing economies have been among the most affected. This vulnerable population faces a threat to their livelihood and way of life. Hence, there is an urgent need to understand the impact of the pandemic on their lives to be able to tackle subsequent waves of the pandemic or similar future exogenous shocks. Purpose We delve into the economic and social disruptions caused by the COVID‐19 pandemic on the employment, sources of income, and lives of different categories of migrant labourers in the Indian state of Kerala. Methods and approach Using the livelihood portfolio theory, we dissect this impact in relation to a wide range of issues. This was corroborated by in‐depth semi‐structured interviews with three categories of respondents. The interview data was analysed by using the directed qualitative content analysis method. We created themes from the data and juxtaposed them with the livelihood portfolio theory in addressing the research objectives. Findings Results highlight the impact on livelihood, lifestyles, migration prospects, and gender aspects. First, households dependent on international migrants were more severely affected than those with family members who were internal migrants. Second, a considerable lifestyle change (more reliance on a plant‐based diet) and borrowing patterns (more reliance on informal money lending) was reported. Third, opinions on future migration prospects were pessimistic, and a trend towards reverse migration was noted. We also captured resilience measures for each of the themes. Policy implications We find that blanket responses to mitigate migrants' hardships could be counterproductive. Policy‐makers ought to implement tailor‐made policies keeping in mind the migrants' classification and socioeconomic demographics. Further, we recommend specific measures to address challenges that women face, to ease their workload and mitigate the loss of income. Specific measures aimed at initiating attitudinal change such as creating mental health awareness, curbing misinformation, and providing counselling services could also add immense value in tackling the pandemic.
