In 2022, emitting 4.8 billion metric tonnes of carbon dioxide (CO2), the United States ranked as the global second-biggest polluter. In order to address this, the US has set a specific target of reducing net carbon dioxide emissions by 50–52 % from the peak of 2006 by 2030. For this reason, identifying the most important elements that will help achieve the SDGs is of the utmost importance. This study looked at how the relationships between green energy transitions (ET), ecological innovation (EI), economic policy uncertainty (EPU), energy consumption (EU), economic growth (EG), and sectoral CO₂ emissions changed from 1982 to 2022. It used advanced Quantile-on-Quantile Regression (QQR) and Quantiles Granger Causality test (QGC). The result highlights a positive correlation between overall sectoral CO2 quantiles and ET quantiles. In the lowest to upper quantiles, EI and sectoral CO2 are slightly positive; however, in the 0.2–0.95 quantiles, the rising slope values demonstrate that EPU affects SCO2. In a similar vein, sectoral CO2 and energy consumption exhibited mixed results across quantiles, while the QQR slope values for sectoral CO2 and economic growth exhibited mixed results throughout quantiles as well. It is crucial to make investments in ET and ecological innovation in order to achieve the Sustainable Development Goals-7 by 2030. This will reduce EPU and ensure that all sectors have access to energy.

Currently, the mining sector is confronted with declining ore grades, volatile energy prices, and environmental pollution from massive carbon emissions. Due to the advantages of RE in terms of emission reduction and cost, some mining companies are actively exploring integrating RE in production to alleviate these challenges. At the same time, the integration of RE in mining sites also faces many obstacles. This paper highlights the importance of incorporating RE into mining projects through a comprehensive review of existing research and analyzes the opportunities and challenges from multiple perspectives. Finally, the conclusions summarize the gaps in existing work and provide appropriate recommendations. The paper aims to inform and provide implications for the transition to RE practices in the mining industry.

Improving energy efficiency in the Residential sector is an important component of the South African National Energy Efficiency Strategy (NEES). This study characterizes the electrical energy consumption of household energy services and appliances, across three income groups, to review the NEES targets in terms of (i) appliance efficiency targets and (ii) likely savings compared to a Reference case where no substantial appliance efficiency improvements are made from 2020 onwards. The results indicate that a significant expansion of the current appliance Minimum Energy Performance Standards (MEPS) is required to achieve the NEES targets and that significant improvement in the aggregate annual energy intensity of appliances is possible if the MEPS is matched to best in class appliances available. A MEPS programme expansion should include both stricter standards as well as an expansion of the basket of appliances affected by this regulation. In the Reference case electricity consumption grows from 46 TWh in 2015 to 66.2 TWh in 2040. A moderate improvement of the current MEPS to match products already available on the market reduces consumption of electricity across all households by 1.5 % (0.8 TWh) in 2030 relative to the Reference case. A more aggressive improvement of the current MEPS to match the best in class products available on the market, as well as an expansion of the basket of appliances, reduces consumption of electricity across all households by 4.4 % (2.4 TWh) and 10 % (6.7 TWh) in 2030 and 2040 respectively relative to the Reference case. The appliances that show the greatest potential for savings are televisions, fridges, chest freezers and ovens.

Renewable energy (RE) auctions have emerged as an essential strategy for countries who want to diversify their energy mix due to the climate change challenges. While earlier research predominantly establishes the fact that bidding positively influences RE capacity, they mostly fail to capture the mixed success that depends on the economic and corporate environment. This study aims to complement it by assessing the effects of RE auctions on the uptake of renewable energy in countries characterized by fluctuations in economic conditions or different business climates. This paper analyzes the factors in bid efficacy with a dataset of 98 countries from 2000 to 2020 through cluster analysis of the corporate climate quality index and DID analysis of sequential policy endogenously. The paper also shows that RE auctions are, on average, a successful policy instrument in growing the share of renewable energy capacity. However, their effectiveness strongly correlates with the context of the country. For countries with stable corporate environments, the average treatment effect is stronger, while for those experiencing financial or structural unpredictability, the issue of RE auctions should be better twiddled. These close results emphasize the need for the elaboration of specific policies concerning auctions that would take into consideration the features of a particular country's economy and legislation. Therefore, to sum it up, RE auctions are a possible instrument for augmenting the worldwide RE generation capacity. However, their potential is not enormous, and the effects are not equitable among all countries. The government should use outcome data to understand the conditions necessary for the long-term success of RE auctions.

The increasing effects of climate change have prompted the initiation of various programs aimed at achieving carbon neutrality and environmental sustainability. Tourism, through activities such as air travel and hotel stay, significantly contributes to global warming. This study examines the relationship between carbon emissions and tourism in China, using data from 1990 to 2022, and applies the Autoregressive Distributed Lag (ARDL) approach to estimate both long-run and short-run coefficients. The results indicate that tourism exacerbates the challenges China faces in achieving carbon neutrality, with long-term carbon emissions being positively correlated with the number of travelers, fossil fuel energy consumption, economic growth, financial development, gross fixed capital formation, and population growth. However, a negative correlation is observed between carbon emissions and the use of renewable energy. These findings are further validated through Fully Modified Ordinary Least Squares (FMOLS), Dynamic Ordinary Least Squares (DOLS), and Canonical Cointegration Regression (CCR) techniques. The study suggests that enhancing the use of renewable energy is crucial for developing sustainable tourism practices and aiding China in its efforts to reach carbon neutrality.

Tourism is a trillion-dollar industry, and sustainable development is a core issue in tourism development in the recent era. Sustainable tourism covers development's social, cultural, economic, and environmental aspects. Tourism development is essential for developed and developing economies because it has a multiplier effect. Tourism showed the potential to attain all 17 Sustainable Development Goals (SDGs). Therefore, this study explores the socioeconomic factors of promoting sustainable tourism in the high, upper-middle, low-middle-, and low-income counties. This study will also explore the effect of sustainable tourism on the economy, energy, and environment. A novel worldwide tourism index is developed, incorporating factors such as domestic tourism consumption, government spending on individuals, capital investment, tourist revenue, and tourism activity. It creates an infrastructure index using multiple indicators like access to clean fuels and technologies for cooking, access to electricity, drinking water, and essential sanitation services. The proposed period for the selected variable will be 1990–2022. therefore, we conducted second-generational unit root and cointegration tests due to the chances of cross-sectional dependence and slope heterogeneity. The regression analysis shows the impact of selected indicators on global tourism using a two-step difference GMM. The regression analysis shows the effect of selected indicators on clean energy, inclusive growth and environment using a two-step difference GMM. The increase in inclusive growth was reported due to increased FDI inflow, Trade openness, financial development, and global tourism in all income groups (upper-middle and low). The decrease in inclusiveness resulted from increased inflation (all panels). The increase in inclusive growth was found to be a 1 % increase in Global tourism growth, FDI, financial development, and infrastructure index. The increase in the global inclusive growth was 0.522 %, 0.4 %, 0.016 %, 0.097 % and 4.287 % for a 1 % increase in Global tourism, trade openness, financial development index, foreign direct investment and infrastructure index., respectively. It is beneficial to encourage financial development in tourism to receive the economic advantages of tourism. Tourism is linked to the generation of foreign currency, enhancing a country's financial stability. Therefore, governments should increase investment in tourism, i.e. transportation, restaurants, and hotels. Ensuring an enabling environment for tourism-related businesses is recommended by eliminating unnecessary regulations and providing credit to small businesses. It is also recommended that tourism-related tax revenue be invested in infrastructural development. The governments should ensure a peaceful environment and quality of institutions. The availability of cultural resources and ICT can also attract tourists.

The persistent disparity between urban and rural incomes in China poses a critical challenge to alleviating energy poverty in rural areas. This study investigates how the income gap between urban and rural regions exacerbates rural energy poverty, focusing on the period from 2005 to 2023, utilizing data from 30 provinces. By employing a two-way fixed-effects model and asymmetry analysis, the research reveals that an increase in the urban-rural income disparity significantly intensifies rural energy poverty. Notably, at higher income quantiles, the gap's effect on energy poverty is more pronounced, while at lower quantiles, its impact is less severe. Financial development, rather than alleviating the situation, is positively associated with rural energy poverty, highlighting an unintended consequence of unequal access to financial services. The results further show that rural regions with limited financial inclusion experience a deepening of energy poverty, with financial service accessibility benefiting wealthier demographics more than the impoverished rural population. These findings imply that targeted policies promoting equitable financial access, narrowing income disparities, and integrating energy poverty reduction strategies are essential to achieving China's Rural Revitalization Strategy.

Technological innovation through various pathways is crucial for achieving carbon neutrality and peak carbon emissions. The Innovative City Pilot (ICP) initiative, a key effort to promote national innovation, has garnered increasing attention. However, most studies have not examined the effects of ICP on carbon emissions through diverse digital technologies. Using city-level data from 2000 to 2022, we constructed a staggered difference-in-differences (DID) model to analyze changes in carbon emissions before and after the ICP period in both ICP and non-ICP areas. The carbon emission reduction pathway of the ICP influences various forms of digital technology, which then empower local green product innovation, market-oriented innovation, and industrial innovation. The impact of ICP emission reduction through digital technology is more significant in western, first- and second-tier, sub-provincial, populous, and coastal cities. In conclusion, policymakers should tailor policies according to the action pathways of digital technology and specific city characteristics. We outline the specific pathways of green product innovation, market-oriented innovation, and industrial innovation enabled by digital technologies and provide policy recommendations for the sustainable development of China.

The Central African Economic and Monetary Community (CEMAC) is at a pivotal juncture in its energy development, facing significant challenges such as increasing emissions and an unreliable energy supply that hampers economic progress. This study assesses the potential for integrating diverse renewable energy (RE) sources into the CEMAC grid, specifically focusing on river hydro, dam hydropower, onshore wind, and solar photovoltaics. Using the EnergyPlan tool, we conduct a dynamic one-year simulation to model energy dispatch on monthly and hourly scales. The modelling result indicates that achieving a 100 % electricity access in the CEMAC region by 2030 will require an annual electricity demand of 8.59 TWh. If this demand is fully met by natural gas (1143 MW), it will result in about 3.75 Mt of carbon emissions. The result shows that by implementing a mix of these renewable technologies in the proposed integrated grid system, the CEMAC region could reduce its carbon emissions by up to 48.7 % relative to using a single RE source in the grid, with annual renewable electricity production of 4.19 TWh/year. Also, by maximising the RE potential from each CEMAC region, there is 49 % RE integration in the proposed integrated grid, with the highest RE share from hydro. This study quantitatively shows that the proposed synchronized regional grid incorporating these renewable sources could enhance electricity reliability and further reduce emissions in the CEMAC region. This research also highlights the transformative potential of RE in achieving sustainable and cost-effective energy solutions for CEMAC, setting a roadmap towards a resilient energy future by 2050.

This study assesses the potential for integrating diverse renewable energy (RE) sources into the CEMAC grid, specifically focusing on river hydro, dam hydropower, onshore wind, and solar photovoltaics. Using the EnergyPlan tool, we conduct a dynamic one-year simulation to model energy dispatch on monthly and hourly scales. The modelling result indicates that achieving a 100 % electricity access in the CEMAC region by 2030 will require an annual electricity demand of 8.59 TWh. If this demand is fully met by natural gas (1143 MW), it will result in about 3.75 Mt of carbon emissions.

The synergistic development of digital transformation and carbon neutrality is a key path to global sustainable development. This study utilized the Broadband China pilot policy and a multi-period Difference-in-Differences (DID) design to comprehensively evaluate the impact of digital infrastructure on carbon neutrality using panel data from 291 prefecture-level cities in China from 2008 to 2021. The results indicate that regional digital infrastructure contributed to carbon neutralization innovation, carbon-intensive industry innovation, and carbon-emission efficiency in the pilot areas. This held true after analyzing the results with propensity score matching, coarsened exact matching, robust estimators, and instrumental variable regression. Specifically, the results of the mediation effect model indicate that digital infrastructure promotes the process of carbon neutrality through several mechanisms, including promoting the rationalization of industrial structure, promoting digital economic development, and inducing innovation in digital technology. In addition, cities with better economic development, lower resource dependence, and weaker environmental constraints have a greater carbon neutrality dividend effect from regional digital infrastructure. These findings indicate a need to optimize policies to unleash the dividends of digital infrastructure in carbon neutrality, which can drive technological, structural, and efficiency changes through digital empowerment. In addition, cities with heterogeneous endowments need to develop targeted measures.
