Special Issue Information

Dear Colleagues,

It is pivotal to achieve net zero CO2 emissions by the middle of this century if we want to limit global temperature rise within 1.5 ℃ compared to pre-industrial levels. Following the declaration of carbon neutrality by many countries, the transition to more sustainable energy, such as the agreement on phasing out the use of coal-fired power (in COP 26), is key to achieving global carbon neutrality. More than 138 countries, including countries such as the US, China, Japan, India, and South Korea, as well as all Member States of the EU, have declared or supported carbon neutrality, and companies such as Apple and Google are also declaring carbon neutrality or participating in the RE100 campaign. The energy sector accounts for about three-quarters of global greenhouse gas emissions, and thus, accelerating energy transition and continuous innovation are required. In such a situation, all initiatives that a government takes to reduce carbon emissions in the energy sector will play a very important role. In particular, the mid-to long-term policy direction should be well established at this early stage. In this Special Issue, any kind of theoretical and empirical study that deals with government policies (as well as firms’ strategies) to mitigate carbon emissions in the energy sector would be welcomed.

The steelmaking industry is responsible for 7% of global CO2 emissions, making decarbonization a significant challenge. This review provides a comprehensive analysis of current steel-production processes, assessing their environmental impact in terms of CO2 emissions at a global level. Limitations of the current pathways are outlined by using objective criteria and a detailed review of the relevant literature. Decarbonization strategies are rigorously evaluated across various scenarios, emphasizing technology feasibility. Focusing on three pivotal areas—scrap utilization, hydrogen integration, and electricity consumption—in-depth assessments are provided, backed by notable contributions from both industrial and scientific fields. The intricate interplay of technical, economic, and regulatory considerations substantially affects CO2 emissions, particularly considering the EU Emissions Trading System. Leading steel producers have established challenging targets for achieving carbon neutrality, requiring a thorough evaluation of industry practices. This paper emphasizes tactics to be employed within short-, medium-, and long-term periods. This article explores two distinct case studies: One involves a hot rolling mill that utilizes advanced energy techniques and uses H2 for the reheating furnace, resulting in a reduction of 229 kt CO2-eq per year. The second case examines DRI production incorporating H2 and achieves over 90% CO2 reduction per ton of DRI. Full article

Advanced metering infrastructure (AMI) is becoming increasingly popular as an efficient means of energy demand management. By collecting energy data through AMI, it is possible to provide users with information that can induce them to change their behavior. To ensure that AMI continues to expand and to encourage the use of energy data, it is important to increase consumer participation and analyze their preferred service attributes. This study utilized a choice experiment to analyze consumer preferences for and acceptance of smart energy services based on AMI data. The results of a mixed logit model estimation show that consumers prefer the electricity information service for individual households and the social safety-net service among convergence services. A scenario analysis confirms that monetary compensation to offset any additional charges is important to maintain the level of consumer acceptance. These empirical findings offer insights for policymakers and companies seeking to develop policies and similar services. Full article

China has adopted a gradualism principle in establishing its carbon emission trading system from the regional pilot markets to a national one. In view of the huge market potential and large differences across China, this paper applies the cointegration test and VECM (Vector Error Correction Model) to investigate the long-run trends and the price dynamics of regional pilot markets. The results show that the prices of the regional pilot markets form three long-run trends exhibit mean-reversion patterns. The launch of the national market marks the different performance of regional pilot markets. After the launch of the national market, the number of long-run trends reduces from three to one and the severity of the mean-reversion patterns is eased, indicating the efficiency improvement in China’s carbon market from a fragmented toward a unified market. The policy implication is that China should further develop its national market by incorporating the regional markets into the national one and encouraging more market participants for market transaction.
