“…To achieve these goals, Japan has reinforced its existing incentive schemes for renewables, including those outlined below. These actions align with Japan's objectives of achieving a low-carbon society and a net-zero society (Dou et al, 2018a(Dou et al, , 2018bFujii et al, 2016;Liang et al, 2016;Togawa et al, 2014Togawa et al, , 2016.…”

The net zero strategy has created a global competition for carbon finance innovation, with over 50 countries and regions aiming for carbon neutrality by 2050 or 2060. This paper provides a preliminary comparative study of carbon neutrality policy instruments in Japan, Singapore and Hong Kong SAR, China: three critical and distinct economies in the Asia-Pacific region. The study examines policies in six categories that support carbon neutrality and compares them based on political economy and market features. The findings reveal that Japan has a rather diverse policy matrix, while Singapore has made rapid progress in carbon finance in a controversial political economy. Hong Kong’s renewable energy policies use a multifaceted approach that emphasizes both carbon emission reduction and environmental quality improvement. Although Hong Kong aspires to become a centre for green finance, it currently lags behind Singapore in this area. The study sheds light on the development and implementation of emerging policies related to carbon neutrality in Asia-Pacific region.

“…Generally, a value of ESI in a range between 1 and 10 implies a system with potential for improvement and that the system is evolving to have better sustainability. A value higher than 10 indicates stagnation and a value lower than 1 implies that the system consumes more than it contributes [ 50 , 51 ]. Based on this index ORC offers an economic contribution in the medium term, where energy from wind offers a performance well above this range which implies that there is not much development or the presence of stagnation, on the other hand, methane, oil, and coal as a source of energy from oil offer a rather deplorable performance in this aspect and it could be considered that its use is not recommended in the long or medium term.…”

“…Liang et al used the number of input flow and the mixture ratio as variables and the emergy index of sustainability as a dependent variable to determine the influence of input flow changes on sustainability changes. He analyzed the importance of biomass production and utilization on the sustainability of hydrogen production systems using this method [68].…”

Two methods of natural ecosystem assessment—emergy analysis (EMA) and life cycle assessment (LCA)—are reviewed in this paper. Their advantages, disadvantages, and application areas are summarized, and the similarities and differences between these two evaluation methods are analyzed respectively. Their research progress is also sorted out. The study finds that EMA and LCA share common attributes in evaluation processes and research fields, but they focus on different aspects of macrocosms and microcosms. The assessment of system sustainability is valued by both EMA and LCA, but the former has unique advantages in natural system input analysis, and the latter is more convincing in assessing environmental loading capacity. If the system boundaries of the two methods are expanded, in other words, factors such as ecosystem services, labor, and infrastructure construction are integrated into the upstream of the target system, and environmental impact is further analyzed using LCA in the downstream of the system, the two approaches would complete each other. The quantified results would be more objective. Therefore, these two theories have the necessity of coupling development. After reviewing recent coupling application cases, the results show that LCA and EMA have commonality in the upstream of the target system (mainly in inventory database construction), while the environmental impact assessment methods are different in the downstream. So the overall coupling analysis method is not formed. The current paper gives rational suggestions on the coupling development of the two systems in terms of the aggregate emergy flow table, the indicator system construction and indicator evaluation methods. In addition, it is necessary to introduce sensitivity analysis and uncertainty analysis in order to improve the reliability of assessment results. At present, the research on the coupling development of the two theories is in rapid development stage, but there are still many problems that need further exploration.
