Globalization’s effects on South Asia’s carbon emissions, 1996–2019: a multidimensional panel data perspective via FGLS

Researchers and policymakers hold diverse opinions about the impact of globalization on environmental degradation. Over the past three decades, increased economic, social, and political interconnections have fueled this debate. However, prior studies have largely overlooked these facets of globalization concerning environmental implications, particularly carbon emissions in developing countries. We contribute to this discourse by examining how various aspects of globalization (economic, social, and political) and two specific measures, de facto and de jure trade, influenced carbon emissions in four selected South Asian countries from 1996 to 2019. The results obtained through feasible generalized least squares (FGLS) reveal that economic globalization increases carbon emissions while social and political globalization reduces them. These results further confirm that, in South Asia, the pollution haven hypothesis is associated only with economic globalization. In contrast, social and political globalization support the world polity theory, indicating potential for positive change. The results also show that both de facto and de jure measures of disaggregated globalization equally influence carbon emissions, suggesting a significant impact from policy interventions. For future environmental sustainability, the governments of these nations should intensify their efforts to strengthen social and political globalization. Meanwhile, the adverse effects of economic globalization can be mitigated by reducing reliance on fossil fuels and providing financial assistance to businesses to encourage the use of renewable energy and modern technology in production.

Regression Analysis of the Impact of Foreign Direct Investments, Adjusted Net Savings, and Environmental Tax Revenues on the Consumption of Renewable Energy Sources in EU Countries

It is very important for EU countries to achieve energy independence. But this is actually impossible without a high level of use or consumption of renewable energy (RE) sources. Important parameters affecting the consumption of RE sources are as follows: foreign direct investments (FDI), adjusted net savings (ANS), and environmental tax revenues. In the presented work, the likely impact of the above indicators on the level of use of RE sources was estimated using a second-order regression equation. As a result, it was established that the growth of the adjusted net savings indicator and an increase in environmental tax revenues (ETR) have a positive effect on the level of use of RE sources. With significant FDI, the level of ANS does not have a very obvious effect on the growth of the level of use of RE sources. An increase in the level of ANS allows for an increase in ETR, which in turn contributes to an increase in the level of consumption of RE sources. It was also established that an increase in the level of ANS contributes to a more complete realization of the potential of FDI for the development of RE. It has been empirically established that a consistently high consumption of renewable energy sources is actually possible in the countries with a high level of adjusted net savings, high environmental tax revenues, and active attraction of foreign direct investments.

However, efficient processing technology, mineral recovery and recycling technology, as well as the use of renewable energy in the mining industry, digital sensors and monitoring, and geographic information technology (GIS) have shown great benefits in reducing environmental impact and increasing resource use efficiency. In addition, appropriate policies and regulations, human resource skills enhancement, community awareness and acceptance, as well as mineral resource diversification and local community empowerment are also important factors in mineral resource conservation.

Environmental Impacts of Household Solar Energy Use Adoption in Murang’a County, Kenya

Although Kenya enjoys an abundant of sunshine throughout the year, most households in counties like Murang’a still use non-renewable sources of energy for their energy needs. Globally, households account for approximately 40% of energy consumption per annum with most needs being heating, air conditioning, cooling and lighting. Environmental management is now a global goal with over 197 nations endorsing a framework that promotes positive environmental impact through renewable energy and reduced C02 emissions during COP21 in Paris. This research mainly focused on positive environmental impacts of solar energy use adoption within households in Murang’a County, Kenya. Guided by the transition theory, the research applied anticipated transitions to discuss different aspects of solar energy use adoption in the county and the impact they have on the environment. This qualitative and quantitative study sought to explore perspectives of various households on solar energy use and how the adoption has positively impacted the environment. The data used for the study was collected from 384 randomly selected households in four constituencies in Murang’a County. The findings of the study established low adoption rates of households’ solar energy use and a direct correlation of adoption levels with the awareness levels for most of the study population. Moreover, the study confirmed the hypothesis that solar energy use adoption in households positively influenced environment through management strategies and improved livelihoods. Furthermore, policy measures to support training as well as financial support would go a long way in increasing uptake of solar energy use in households in Murang’a County thus positively influencing the environment through management strategies such as renewable energy use

How Clean Can We Get? Technological Change and Renewable Energy Use in Mexico, A General Equilibrium Perspective

This study explores the impact of technological change and renewable energy adoption on Mexico's economy using a Computable General Equilibrium (CGE) model. As global concerns about climate change intensify, reducing carbon emissions has become a priority, but traditional CGE models often predict significant economic costs associated with fossil fuel restrictions. In this analysis, we modify the conventional CGE framework to incorporate increasing returns to scale and endogenously modeled technological change, reflecting the real-world diffusion of renewable energy technologies in developing countries like Mexico. By accounting for these factors, our model demonstrates that a combined policy of carbon taxation and renewable energy subsidies can achieve significant CO2 reductions without negatively impacting economic welfare. However, while the environmental benefits—such as reduced emissions of particulates, SO2, and NOx—are substantial, the overall welfare gains remain modest, and the policy's success depends on effective government implementation and potential trade impacts. These findings offer valuable insights for policymakers in Mexico and other developing nations seeking to balance economic growth with environmental sustainability through strategic carbon emission reduction policies.

Proposal for zero energy housing designs in Jordan

BackgroundAchieving zero-energy targets in residential buildings is challenging due to improper energy design and the selection of energy-related systems. Moreover, the absence of benchmarks for zero-energy residential buildings, along with the scarcity of studies tailored to diverse climates and building characteristics, highlights the urgent need for further research. This study aimed to address these gaps by designing zero-energy buildings to suit diverse climate zones in Jordan, acting as benchmarks to enhance energy efficiency and promote renewable energy use in the residential sector.MethodsEnergy simulation tools were employed to design and verify zero-energy systems. The energy use intensity (EUI) results from the IDA ICE tool were compared with the reported targets and OpenStudio tool outcomes, ensuring that deviations among the proposed designs within the same climate zone consistently remained within acceptable limits, averaging 2, 1, and 1 kWh/m2 year in 1B (very hot dry), 2B (hot dry), and 3B (warm dry), respectively. Additionally, an economic evaluation was conducted by comparing the cost estimates of a Jordanian code-compliant house and the most acceptable proposed zero-energy design.ResultsThe proposed designs exhibited average EUI values of 64.4, 64, and 60 kWh/m2 in diverse climate zones. Outperforming typical Jordanian houses by 56%, 55%, and 60% in 1B, 2B, and 3B, respectively, these designs surpassed national and international benchmarks by at least 35%. Notably, the proposed zero-energy designs achieved substantial cost savings of 1938 USD, equivalent to 11 USD per square meter, throughout the construction phase.ConclusionsConsidering Jordan’s ambitious energy strategy for 2030 and the significant energy consumption in the residential sector, the proposed zero-energy building designs play a crucial role in advancing the national transition towards zero-energy buildings. This study provides valuable insights by presenting precise designs, benchmarks, and a comprehensive guide tailored to Jordan’s distinctive building and climate characteristics with potential applications beyond its immediate context.

Ultra-short-term global horizontal irradiance forecasting based on a novel and hybrid GRU-TCN model

The need for energy is increasing globally due to a several factors, including population growth and economic development. Achieving this energy demand in the face of global warming and the depletion of fossil fuels requires the use of renewable energy. Photovoltaic energy is one of the renewable energy sources that is widely used in many nations across the world. Photovoltaic (PV) energy integration into the grid has significant benefits for the environment and economy, but at high penetration levels, its intermittent nature makes system stability difficult to maintain. Accurate ultra-short-term global horizontal irradiance forecasting is necessary in order to guarantee the most optimal use of photovoltaic power production sources. For GHI forecasting, a novel GRU-TCN-based model is proposed in this paper. It is composed of two neural networks: a temporal convolutional network and a gated recurrent unit. After extracting the temporal features from time-series solar irradiance data using GRU, the spatial features are obtained from the correlation matrix of different meteorological variables of the target and its neighbor position using TCN. Univariate and multivariate GRU-TCN models have been used for GHI ultra short-term forecasting. This paper compares the univariate and multivariate GRU-TCN models with TCN, LSTM, and GRU models based on three evaluation metrics in order to investigate how different combinations of variables affect the accuracy of the GRU-TCN models for one-step forecasting. The findings indicate the adoption of a univariate model using historical data of GHI is suitable to obtain reliable forecasting with 23.02 (W/m2) in MAE as opposed to the best multivariate model that achieved 25.67 (W/m2) in MAE. According to the results, the proposed model outperforms the other models assessed and offers a practical alternative for ultra-short-term GHI forecasting.

Financial inclusion and environmental pollution in sub-Saharan Africa: moderating effects of economic growth and renewable energy

A thriving literature exists about the role of financial inclusion in socio-economic development. Nevertheless, the environmental effects of financial inclusion are largely unknown in the literature, especially in sub-Saharan African countries. Therefore, this study explores the association between financial inclusion and CO2 emissions utilizing data from 23 sub-Saharan Africa for the period 2004–2019. Based on different estimation methods such as dynamic ordinary least squares (DOLS), fully modified ordinary least squares (FMOLS), canonical correlation regression (CCR), and an instrumental variable generalized-method of moment (IV-GMM), the results show that financial inclusion is responsible for a substantial increase in CO2 emissions. In addition, financial inclusion moderates economic growth, resulting in higher CO2 emissions. Alternatively, financial inclusion moderates renewable energy use to lower CO2 emissions. The outcomes also verify the presence of the Environmental Kuznets Curve hypothesis (EKC). This study proposes uniting financial inclusion and environmental policies as a strategy for reducing CO2 emissions in sub-Saharan Africa.

How effective is the carbon pricing implementation in ASEAN Member States to reduce regional emissions

Abstract At the Conference of the Parties of the UNFCCC (COP 27), the ASEAN Member States (AMS) reaffirmed their commitment to the Paris Agreement by pledging to achieve net zero or carbon neutrality targets by 2050. According to the 7th ASEAN Energy Outlook (AEO7) study, ASEAN’s GHG emission will rise 3.7-fold to 6,704 MtCO2-eq in 2050 from 1,815 Mt in 2020. This will require all AMS to scale up their efforts to reach their greenhouse gas (GHG) emission target, and one of them is by introducing carbon pricing to smoothen the transition by encouraging more renewable energy use. Currently, some AMS have already introduced or proposed carbon pricing. Singapore has introduced carbon tax implementation since 2019. Indonesia has been stepping up its commitment to enforce both carbon tax and emission trading system (ETS) by introducing numerous supporting policies. Malaysia, Thailand, and Vietnam are anticipating launching ETS as their latest climate action plan. A question on how effective carbon pricing implementation to reduce regional emission may come up and this paper shed lights to answer this question through expert interviews and literature reviews. The findings indicate that carbon pricing may reduce emissions, especially from power generation and manufacturing industry, and support the transition to a low-carbon economy, helping the region reach carbon neutrality or net zero targets by 2050.

Advancements and challenges of industrial‐level acidic CO2 electrolysis

AbstractThe use of green renewable energy to convert carbon dioxide (CO2) into valuable chemicals and fuels through CO2 electrolysis technology (also known as electrochemical CO2 reduction reaction, eCO2RR) is an advantageous technology, which could greatly aid the global carbon‐neutral goal. Although progress has been made in alkaline/neutral media, low carbon conversion efficiency to target products, carbonate/bicarbonate salt precipitation, and blockage of electrode holes caused by CO2 are not conducive to industrial applications. Acidic media could address these issues; however, in these conditions, there are other challenges that need to be addressed, such as hydrogen evolution, poor tolerance of electrocatalysts, and electrolysers. This review discusses recent advances in industrial‐level acidic CO2 electrolysis, including reaction mechanisms, electrocatalysts, and device design, aiming to promote its commercialization. In addition, a comprehensive evaluation strategy of an acidic eCO2RR system is proposed, and perspectives are provided based on related discussion.

The development of automatic plant watering devices has become a major focus in increasing efficiency and effectiveness in plant cultivation. In this context, automatic plant watering devices that use electrical energy sources from solar panels have shown great potential in saving energy and reducing environmental impacts. This tool is designed to replace manual work in watering plants, both in hydroponic systems and sprinkler systems. In hydroponic systems, automatic plant watering devices use soil moisture sensors to detect soil moisture and send commands to the water pump to water periodically. This allows hydroponic plants to receive nutrients continuously and maintain air humidity with automatic fogging. Meanwhile, in sprinkler systems, automatic plant watering devices use solar panels as a source of electrical energy. These solar panels generate electrical energy that is used to power the water pump and sprinkler, thus watering plants automatically without the need for human intervention. The advantages of using solar panel in automatic plant watering devices include the use of renewable energy, easy maintenance, and no greenhouse gas emissions. However, this tool also has disadvantages, such as dependence on sunlight intensity. Thus, the development of automatic plant watering devices using solar panel can help increase plant productivity, save energy, and reduce environmental impacts. This tool can also be integrated with various types of plant cultivation systems, thus providing many benefits in the development of modern agricultural technology.

Sourcing renewable energy components: building resilient supply chains, reducing dependence on foreign suppliers, and enhancing energy security

The transition to renewable energy is essential for mitigating climate change and ensuring long-term energy security. As global demand for renewable energy technologies grows, establishing resilient supply chains becomes crucial. This paper examines strategies to build robust supply chains, reduce reliance on foreign suppliers, and enhance energy security. A major challenge in renewable energy is the dependence on a limited number of international suppliers, which risks supply disruptions due to geopolitical tensions, trade restrictions, or natural disasters. Diversifying suppliers can mitigate these risks by encouraging alternative suppliers and fostering competition (Smith, 2020). Local manufacturing is another critical strategy, promoting supply chain resilience, economic growth, and job creation. Countries like the United States and Germany have incentivized local manufacturing of solar panels and wind turbine components (Jones, 2021), ensuring a steady supply of parts and aligning with broader industrial policies. Maintaining strategic reserves of critical materials, such as rare earth elements and lithium, is essential for buffering against supply disruptions and price volatility, ensuring continuous production of renewable energy technologies (Brown, 2019). Strategic planning and investment in reserves are vital for a comprehensive energy security strategy. Technological innovation enhances supply chain resilience. Advances in materials science, manufacturing processes, and recycling technologies can reduce dependence on scarce materials and improve renewable energy system efficiency. Developing alternative materials for battery storage, for example, can reduce reliance on lithium and cobalt sourced from unstable regions (White, 2022). Public-private partnerships (PPPs) are crucial for advancing the renewable energy sector. By leveraging both sectors' strengths, PPPs can accelerate technology deployment, improve infrastructure, and foster innovation. Successful examples include government-private collaborations on offshore wind farms and smart grid technologies (Green & Associates, 2021). Favorable trade policies facilitate the global exchange of renewable energy technologies and components. Reducing tariffs, streamlining customs, and fostering international cooperation can enhance supply chain efficiency and reliability (Lee, 2020). This study advocates for trade agreements tailored to the renewable energy sector's needs. Integrated energy systems and smart grid technologies optimize renewable energy use and distribution. Advanced monitoring and control systems improve grid stability, reduce energy waste, and enhance renewable source integration (Adams, 2019). Investment in smart grid infrastructure is crucial for a resilient energy strategy. Robust policy frameworks are necessary to support these initiatives. Governments must enact policies providing clear guidance, incentives, and support for resilient renewable energy supply chains, including ambitious renewable energy targets, financial incentives for R&D, and regulatory stability (Martinez, 2021).
