Consumers are conscious of increasing online purchases and demand sustainable consumption friendly actions. Although there is increasing interest in this topic, the research status, development, and structure of consumer behavior and sustainability in e-commerce research is scarce. This study aims to analyze the intellectual, conceptual, and social knowledge of consumer behavior and sustainability in e-commerce research to generate new understandings. Data from 104 articles were collected from the Scopus database, and a bibliometric analysis was conducted. Results revealed a close relationship between the topic and city logistics, big data analysis, customer engagement, circular economy, online services, and omnichannel retail, showing the different research approaches and the transversal themes related to the topic. This study contributes to the sustainability academic research by identifying trends and suggesting future research topics.

Global Research Trends in Consumer Behavior and Sustainability in E-Commerce: A Bibliometric Analysis of the Knowledge Structure

This study aims to present a bibliometric analysis and literature review and to identify publications, main topics, and trends in recent years about the sustainability of logistics operations in e-commerce environments. For this, we considered 99 documents from Scopus published in 2021 and 2022 that address logistics, e-commerce, and sustainability. The bibliometric analysis shows that authors from Italy and India stand out for generating the largest number of publications, and correspondingly, institutional affiliations from these countries present the largest scientific production. It is established that journals such as Sustainability, International Journal of Logistics Research and Applications, and Sustainable Cities and Society lead both in the number of published articles and the number of articles with the highest citations. Within the main topics are the sustainability of e-commerce logistics, last-mile logistics and delivery logistics, urban and city logistics, environmental impact, urban transport, packing and packaging, traffic and congestion, supply chains, the effects of the COVID-19 pandemic, China and cross-border e-commerce, vehicle routing, optimization methods, and decision-making techniques in operations for cost and energy efficiency. Similarly, this study identifies the main research trends related to multiple dimensions of sustainability; technological developments including electric vehicles and specialized software; crowdshipping; operation modes such as collection and delivery points, parcel lockers, and micro-depots; and policymaking.

Sustainable Logistics for E-Commerce: A Literature Review and Bibliometric Analysis

Industries nowadays face difficulties due to different environmental policies for the well-being of society and competitive scenarios. Similar categorized products always give tough competition to each other as those are substitutable in nature and this study deals with a single type of substitutable product. The effectiveness of a variable production system under emissions control policies is observed for this type of product. Carbon tax, cap-and-trade policy, and green technology are used to make the variable production system emission-controlled. A dual-channel policy is utilized to find the most profitable managerial decisions. This is a fully emission-controlled variable production system covered by green technology investment. Every stage of the variable production system i.e., setup, production, and holding of products emit less carbon than the projected carbon cap. This helps to receive the subsidy from the government. That means an emission-controlled variable production system with dual-channel for substitutable products is established under green technology. The classical optimization procedure helps to find the global optimum solution of the cycle time, green technology, the selling price of products, and the production rate. Numerical study proves that the proposed system provides 8.76% more profit than the traditional production system. Finally, a sensitivity analysis is carried out for the managerial implications of cost parameters on the optimal total profit. • A green flexible production system is studied with reworking. • Manufacturers invest on green technology for less carbon emission from the system. • Manufacturers produce substitutable products and sell them by dual-channel policy. • Less amount of emission from system ensures more subsidy from government.

Effect of green investment to reduce carbon emissions in an imperfect production system

A Vendor-Managed Inventory Model for Imperfect Production Process Using Sustainability Investment and Energy Consumption Under Different Carbon Policies

Many nations have created ecological policies and regulations to prevent industries from emitting excessive amounts of carbon emissions into the environment. While significant progress has been achieved in the direction of sustainable growth, many nations still rely on nonrenewable energy sources. This study explores the viability of investing in green technology to achieve the optimal decisions (lot sizes, lead time, and green investment amount) in a two-echelon supply chain system by considering human error with two carbon emission strategies: carbon taxes and limited carbon emissions. It entails the inspection of every shipped lot by the buyer to identify defective products that could have resulted from the vendor’s production process. We show a constrained non-linear program and design a calculus-optimization technique to solve it. The methodology used in this research is the quantitative method, which is based on the principles of operations research, and the models are built on mathematically oriented inventory theory. The results imply that an outsized ecological carbon footprint can be reduced without compromising customer service by designing optimal inventory strategies. The findings also confirm that green investment is the greatest economical method for reducing carbon emissions and system costs.

Sustainable Supply Chain System for Defective Products with Different Carbon Emission Strategies

Most of the consumers relied heavily on e-commerce for products and services for the past few years due to the recent COVID-19 pandemic. This kind of an unexpected behaviour among the consumer society has taken every industry by surprise so that many industries have begun operating online and offline businesses to ensure future competitiveness. Firms introducing online sales are deplorably facing many challenges in terms of logistics and delivery processes, such as short lead times, flexible delivery, capacity of warehouse, and the production process for controlling carbon emissions. Keeping these challenges in mind, a sustainable dual-channel vendor-buyer supply chain model has considered for a controllable emission under fuzzy demand and energy consumption. The model deals with limitation on warehouse floor-space area, and the warehouse divides into two stages such as one for satisfying online orders and the other for satisfying offline orders. The demand rate and energy consumptions are treated as the trapezoidal fuzzy number, and we use the signed distance method to defuzzify the fuzzy joint expected total cost. The objective focuses on obtaining a trade-off between cost and emissions, thereby determining the optimal production-distribution strategy and a proper sustainable plan for handling both online and offline orders. The aforesaid scenario is mathematically formulated in the form of constrained non-linear programme (NLP) and derive a Lagrangean multiplier method to solve it. An iterative solution algorithm is designed, and for better illustration of the developed theory, numerical analysis is carried out followed by a wide discussion on the sensitivity analysis for various parameters. Our results indicate that the optimal solutions of the sustainable fuzzy model slightly fluctuate from the solutions of the sustainable crisp model. According to results, considering the uncertainty in the system is a crucial factor to achieve the economic and environmental sustainability of the production sector. The research reveals that the practitioners should be careful in accounting flexibility in the input factors demand and energy to tackle the uncertainties that always fit the real situation.
