A revolution in the energy sector is crucial for achieving environmental sustainability since almost three-fourth of global carbon dioxide emissions is generated from the energy sector. It is believed that combustion of unclean energy resources is the major contributor to the multifaceted environmental adversities experienced across the globe. Thus, the development of clean energy technologies, to elevate their shares in the global energy mix, is deemed necessary to reinstate environmental well-being worldwide. Against this background, this study aims to explore the symmetric and asymmetric impacts of public research and development investments for nuclear and renewable energy development and economic growth on carbon dioxide emissions in the context of Japan over the 1974–2017 period. As opposed to the conventional approaches, this study contributes to the literature by specifically scrutinizing the environmental effects associated with public investments in clean energy development projects; whereas the majority of the preceding studies have either considered the environmental impacts associated with the overall research and development investments in the energy sector or that made by firms in general. However, evaluating the effects of such investments for clean energy development is more appropriate for policy-making purposes. The results from both the symmetric and asymmetric analyses reveal that higher public investments in clean energy research and development-oriented projects help to curb carbon dioxide emissions in Japan. Besides, such investments for nuclear energy development are evidenced to be relatively more effective in facilitating the nation's carbon emission-abating agenda. In contrast, economic growth in Japan is evidenced to trigger higher carbon dioxide emissions. In line with these key findings, this study offers several policy-level suggestions in respect of undergoing clean energy transition and achieving environmental sustainability in Japan.

Moderating Role

Background: Air pollution is one of the major threats to human health and well-being. This study aimed to explore the effect of renewable energy consumption and carbon dioxide emissions on tuberculosis (TB) incidences. It further investigates the moderating role of urbanization on the relationship between underlying factors and TB. Methods: The data of 183 countries over the period 2000 to 2014 were collected and a two-step system GMM technique was utilized to reduce the endogeneity issue. Additionally, we divided the sample into two sub-panels based on country risk for more robust estimates. Results: Carbon dioxide emissions increase the incidences of TB while renewable energy consumption could restrict these cases. On the other hand, urbanization is positively associated with TB in high-risk. System-GMM estimates also indicated that urbanization further strengthens the positive association between CO2 emissions and tuberculosis. Conclusion: Climate-friendly energy technologies, surveillance, and adequate city planning can act as effective mechanisms to improve public health.

In this paper, we modeled the effects of income, agricultural innovation, energy utilization, and biocapacity on Carbon dioxide (CO2) emissions. We tested the validity of the environmental Kuznets curve (EKC) hypothesis for Nigeria from 1981 to 2014. We applied the novel dynamic autoregressive distributed lag (ARDL) simulations to develop conceptual tools for policy formulation. The empirical results confirmed the EKC hypothesis and found that agricultural innovation and energy utilization have an escalation effect on CO2 emissions whereas income and biocapacity have long-run emission-reduction effects. The causality results found agricultural innovation attributable to CO2 emissions and observed that income drives energy demand. Income, biocapacity, and energy utilization are found to predict changes in CO2 emissions. These results are validated by the innovation accounting techniques—wherein 22.79% of agricultural innovation corresponds to 49.43% CO2 emissions—5.95% of biocapacity has 35.78% attributable CO2 emissions—and 1.61% of energy spurs CO2 emissions by 16.27%. The policy implication for this study is that energy efficiency, clean energy utilization and sustainable ecosystem recovery and management are the surest ways to combat climate change and its impacts.

The 14th Five-Year Plan is the first five-year period in which China begins a new journey to build a modern socialist country in an all-round way, and also the first five-year period after China set a goal of achieving carbon neutrality by 2060. In this important historical context, the energy development of China during the 14th Five-Year Plan period will be of great historical transformation significance. As a crucial factor, the trend of energy development during the 14th Five-Year will have a direct impact on the medium and long-term economic and social development, as well as on our confidence in achieving the goal of carbon neutrality. The improvement of standardization is conducive to promoting China’s energy demand and economic growth, and it plays an important role in peaking carbon dioxide emissions and reaching the goal of carbon neutrality in the future.

AbstractWind power and electric vehicles can help reduce carbon dioxide emissions and improve air quality. However, these technologies rely on rare metals whose extraction requires large amounts of energy and water and are high in carbon emissions. Here we consider the sustainability of both technologies and the impacts of rare earth elements co-extraction. We use a global dynamic material flow-stock model and several scenarios for rare earth elements demand and supply. Cumulative carbon dioxide equivalent emissions associated with rare earth metals oversupply was between 5.5 and 6.4 times the emissions associated with dysprosium and neodymium production when dysprosium demand was increased. Carbon dioxide equivalent emissions associated with metals extraction and production were equivalent to between 10% and 29% of carbon dioxide emissions reduction through electric vehicle use. Targeting metal rich deposits and increased material efficiency and recycling reduced carbon dioxide emissions by 78%, 39% and 35%, and combined by 90%. Our findings highlight the role of resource efficiency and recycling in enhancing clean energy technologies.

The Impact

In January 2008 the Governor of Hawaii announced the Hawaii Clean Energy Initiative; an initiative that aims to have at least 70 percent of Hawaii’s power come from clean energy by 2030 [4]. In July 2009, the Hawaii Department of Accounting and General Services awarded NORESCO, an energy service company, a $33.9M contract to improve the energy efficiency of 10 government buildings. The avoided utility cost of the energy and water savings from the improvements is the project funding mechanism. The energy savings realized by the project will reduce carbon dioxide emissions associated with utility power generation. However, as renewable energy becomes a larger portion of the utility generation profile through the Hawaii Clean Energy Initiative, the carbon dioxide emissions reductions from specific energy efficiency measures may erode over time. This work presents a method of analysis to quantify the carbon dioxide emissions reduction over the life of a project generated by energy efficiency upgrades that accounts for both the impact of policy initiatives and climate change using DOE-2/eQUEST. The analysis is based on the fact that HVAC energy usage will vary with climate changes and that carbon dioxide emission reductions will vary with both energy savings and the corresponding utility’s power generation portfolio. The energy savings related to HVAC system energy efficiency improvements are calculated over the life of a 20 year performance contract using a calibrated DOE-2/eQUEST model of an existing building that utilizes weather data adjusted to match the predictions of the Intergovernmental Panel on Climate Change. The carbon dioxide emissions reductions are calculated using the energy savings results and a projection of the implementation of the Hawaii Clean Energy Initiative. The emissions reductions are compared with other analysis methods and discussed to establish more refined expectations of the impact of energy efficiency projects in context with climate changes and policy initiatives.
