The purpose of this paper is to explore and investigate the measurement of a carbon footprint and environmental program in supply chain management.

The study uses a case study methodology and employs the qualitative methods of interviews and document analysis to collect data on Hyundai Motors Co. (HMC) and its key first‐tier supplier, referred to here as Supplier A, in the Korean automobile industry.

The results of the study show that a key strategic action to implement carbon management is to identify and measure the carbon footprint of products and processes within the supply chain. A carbon footprint measurement framework and different levels of CO₂ adoption categories developed at HMC are presented. By monitoring and evaluating suppliers' CO₂ emissions performance, a focal company may avoid carbon‐related risk and retain competitiveness based on its supply chain.

Developing a carbon footprint measurement and evaluation program in the supply chain provides a track record to improve carbon and energy efficiency. This may lead companies to develop and exploit greater energy efficiency to tackle carbon emission challenges in the supply chain.

This paper provides academics and managers with a new approach to consider carbon management and green supply chain management.

Considering both the current opportunities of the Internet of things (IoT) and aviation, as well as the potential opportunities they may offer for the future, it is understood that they are among the important issues that need to be examined in the literature. This study aims to provide an idea by conducting bibliometric and visualization analyses of the current trends and development opportunities of IoT and aviation.

In this study, descriptive and bibliometric analyses within the framework of co-author, co-citation, bibliographic coupling, and keyword co-occurrence analysis were carried out for publications found to be published between 2007 and 2023 in the Web of Science (WoS) database related to IoT and aviation. VOSviewer (ver. 1.6.18) program and the Biblioshiny application were used to create bibliometric networks and provide visualization.

As a result of some descriptive and visualization analyses, the current trend of publications on IoT and aviation and future publication opportunities has been revealed. It has been understood that the subject of IoT and aviation is one of the subjects whose number of publications has increased in recent years and has not yet fully matured in terms of the number of publications and has the potential to make new publications.

In this study, bibliometric analysis of IoT and aviation, which could not be found examined before in the literature, and the creation of existing bibliometric networks by visualizing were carried out.
