Barriers for Business to Engage in Carbon Trading Through the Indonesian Carbon Exchange: An Analytical Hierarchy Process Approach

/in /by

This study investigates the barriers faced by businesses in participating in carbon trading through the Indonesia Carbon Exchange (IDXCarbon). Although Indonesia has committed to reduce greenhouse gas emissions by 31.89% with national efforts and 43.20% with international assistance, participation in IDXCarbon is still limited. Using the Analytical Hierarchy Process (AHP) method, this study identifies and ranks barriers based on expert evaluation in four main criteria:  Impact on Risk Management and Uncertainty; Impact on Business Operation and Strategy; Impact on Financial and Profitability, and Impact on Regulatory Compliance and Stakeholder Engagement. The main barriers identified were Concern Over Loss of Sustained Revenue; Lack of Company Understanding and Capability; Additional Explicit Costs; Bureaucratic Complexity; Low Level of Transparency; and Limited Trading Volume. The results of this study are expected to guide policymakers and business leaders in improving their effectiveness and participation in carbon trading, thereby contributing to Indonesia’s ambitious emissions reduction targets.

Bibiliometric Analysis of The Literature on Organizational Readiness: Mapping and Direction

/in /by

The COVID-19 pandemic is mostly responsible for the decline in business financial performance. It is believed that the company’s survival is contingent upon the organization’s readiness to integrate digital technology at the operational and strategic levels. Despite the abundance of literature in this field, there has been no empirical research to characterize previous studies or provide guidance for future studies that have a significant impact. Therefore, we have designed this investigation to fill this gap. The bibliometric analysis method employed in the research involves the initial step of conducting a search of the Scopus-indexed journal database using the title, abstract, and keywords “organizational readiness”, “readiness to change”, “digital maturity” or “digital capability”. We selected a total of 3528 articles from a pool of 93,307 by applying filters based on specific topics and time periods. Following this, we compiled the meta data using the Publish and Perish (PoP) program and generated research trend visualizations using Vosviewer. The research findings indicate that Parida, V., a Swedish writer, is the most productive. However, we discovered that the authors who published the most impactful articles were not necessarily the most prolific authors or countries. Following the COVID-19 pandemic, research on organizational readiness that can assist small and medium-sized businesses in gaining a competitive advantage and enhancing their value could be the next area of investigation.
