| Summary/Abstract |
Recently, the progress of reaching carbon emission peaks and achieving carbon neutrality has had significant impacts on the global economy. The overall societal efforts on carbon emission reduction from various industries will likely be strengthened, thanks to the advantages enterprises could gain in digital technologies through a structural upgrade in the energy systems. Based on China's provincial panel data from 2011 to 2019, this paper constructs a spatial panel Durbin model and a mediating effect model to investigate the mechanism and influence of the digital economy on carbon emission reduction. The results show that (1) the development of the digital economy has a significant spatial spillover effect on carbon emission reduction; (2) the digital economy influences carbon emission reduction both directly and indirectly. This means that the carbon emission reduction can be affected indirectly by the digital economy through the transformation of energy structure; (3) the carbon emission reduction effect of the digital economy exhibits regional heterogeneity, it is more prominent in eastern regions than in other areas. The above findings provide substantial empirical evidence to policymakers on how to best promote the development of the digital economy and intensify the coordination of China’s digital infrastructure in regional environmental governance.

The long-term forecasting of energy supply and demand is an extremely important topic of fundamental research in Taiwan due to Taiwan's lack of natural resources, dependence on energy imports, and the nation's pursuit of sustainable development. In this article, we provide an overview of energy supply and demand in Taiwan, and a summary of the historical evolution and current status of its energy policies, as background to a description of the preparation and application of a Long-range Energy Alternatives Planning System (LEAP) model of Taiwan's energy sector. The Taiwan LEAP model is used to compare future energy demand and supply patterns, as well as greenhouse gas emissions, for several alternative scenarios of energy policy and energy sector evolution. Results of scenarios featuring "business-as-usual" policies, aggressive energy-efficiency improvement policies, and on-schedule retirement of Taiwan's three existing nuclear plants are provided and compared, along with sensitivity cases exploring the impacts of lower economic growth assumptions. A concluding section provides an interpretation of the implications of model results for future energy and climate policies in Taiwan.

| Summary/Abstract |
While the popularity of emission trading schemes (ETS) has exceeded that of carbon taxes, ETS is not applicable to all countries. This paper investigates the increasing block carbon tax (IBCT), which is a modified carbon tax based on the increasing block tariffs theory. The IBCT considers the size bias in emission reduction, and this paper discusses whether it is suitable for small Asia-Pacific countries (SAPCs). Both theoretical analysis and numerical simulation were used to compare the impacts of IBCT and flat carbon tax (FCT) on the emission reduction behavior of manufacturers in both purely competitive and co-opetitive market environments. This study demonstrates that the IBCT is better than the prevailing FCT, and the results indicate that this could be a better choice for SAPCs. The implementation of the IBCT policy in SAPCs can protect domestic manufacturers and decrease the risk of carbon leakage. The IBCT promotes low-carbon production when the manufacturers expand their scale, which can lead to a win-win situation for social welfare and environmental development. We suggest that the IBCT should be implemented in high-carbon industries; its formulation needs more market details than FCT. Besides the policy, the development of reduction technologies also cannot be ignored.

| Summary/Abstract |
Following the announcement of the China's 2020 national target for the reduction of the intensity of carbon dioxide emissions per unit of GDP by 40-45% compared with 2005 levels, Chinese provincial governments prepared to restructure provincial energy policy and plan their contribution to realizing the State reduction target.
Focusing on Fujian and Anhui provinces as case studies, this paper reviews two contrasting policies as a means for meeting the national reduction target. That of the coastal province of Fujian proposes to do so largely through the development of nuclear power, whilst the coal-rich province of Anhui proposes to do so through its energy consumption rate rising at a lower rate than that of the rise in GDP. In both cases renewable energy makes up a small proportion of their proposed 2020 energy structures. The conclusion discusses in depth concerns about nuclear power policy, energy efficiency, energy consumption strategy and problems in developing renewable energy.

| Summary/Abstract |
The transportation sector has significantly contributed to greenhouse gas and air pollutant emissions. Based on the Kaya constant equation and the LMDI decomposition model, A synergistic reduction effect model of transportation tailpipe Environmental negative externalities emissions is constructed to adopt the inter-provincial panel data of China from 2005 to 2019. The synergistic reduction emission impact and indirect drivers between air pollution and carbon emission are analyzed. The results show that the drivers of the synergistic impact are mainly energy efficiency and industrial structure. Significant synergistic emission reduction effects exist in eastern China, western China, medium-sized transportation markets, and less developed tourism regions. Further, increasing environmental regulation can improve the synergistic reduction impact of the transportation sector's air pollutants and carbon emissions. This paper provides theoretical support for winning the battle of pollution prevention and control and achieving the "dual carbon" goal in the new era.
