Estimating price elasticity of demand for mineral commodities used in Lithium-ion batteries in the face of surging demand

The accelerating adoption of clean energy technologies is driving demand for certain mineral commodities like lithium, essential for electric vehicle batteries. Understanding the influence of the energy transition on each market requires examining their supply and demand price elasticities. However, there have only been a limited number of studies that have estimated mineral demand price elasticities in emerging technologies. We empirically estimate the price elasticity demand (PEDs) for mineral commodities used in lithium-ion battery cathodes and anodes—cobalt, graphite, lithium, manganese, and nickel. We also test whether the price elasticities of these mineral commodities have changed due to any structural changes in recent years, given the recent expansion in the sales of electric vehicles. Using Two Stage Least Squared (2SLS) econometric techniques, we find that demand has become less elastic for lithium (-0.11), cobalt (-0.45), nickel (-0.09), and manganese (-0.04) after structural breaks in 2020, 2013, 2009, and 2014, respectively. In contrast, demand for natural amorphous graphite (-0.36), and natural flake graphite (-0.58) remains relatively stable over the time period assessed.

Clean energy synergy with electric vehicles: Insights into carbon footprint

This study empirically examines the impact of Electric Vehicles (EVs) and clean energy adoption on carbon footprints. With growing concerns over climate change and the need to reduce greenhouse gas emissions, the transition to electric vehicles and clean energy sources has gained significant attention as potential solutions. This research investigates the relationship between the adoption of EVs and clean energy technologies and their subsequent effect on carbon footprints. The study applied the Generalised Method Moments (GMM) on the data sourced from the International Energy Agency (IEA) and the World Development Indicators (WDI) for the period 2011–2021 covering 27 countries. The findings reveal a strong correlation between the adoption of EVs and reductions in carbon footprints. It shows that a 1 % increase in renewable electricity output would result in a 0.5 % decline in carbon footprints. This implies that, as EV sales increase, the overall carbon emissions from the transportation sector decrease, primarily due to the lower emissions associated with electric vehicles compared to conventional internal combustion engine vehicles. Additionally, the study finds that the integration of clean energy sources into the electricity grid further contributes to carbon footprint reductions. The use of renewable energy in charging EVs minimizes the indirect emissions associated with electricity generation. The research concludes that the widespread adoption of EVs and clean energy sources has the potential to significantly reduce carbon footprints and mitigate the impact of climate change. However, it emphasizes the importance of continued technological advancements, increased availability of charging infrastructure, and supportive government policies to accelerate the transition towards a low-carbon transportation and energy system. Therefore, the study highlights the need for collaborative efforts among governments, industry stakeholders, and individuals to foster sustainable practices and achieve a more environmentally friendly future.

Environmental and Economic Clustering of Indonesian Provinces: Insights from K-Means Analysis

Indonesia's archipelago presents a distinctive opportunity for targeted sustainable development due to its complex interplay of economic advancement and environmental challenges. To better understand this dynamic and identify potential areas for focused intervention, this study applied K-means clustering to 2022 data on the Air Quality Index (AQI), electricity consumption, and Gross Regional Domestic Product (GRDP). The analysis aimed to delineate the provinces into three distinct clusters, providing a clearer picture of the varying levels of economic development and environmental impact across the nation's diverse islands. Each cluster reflects specific environmental and economic dynamics, suggesting tailored policy interventions. The results show that for provinces in Cluster 1, which exhibit moderate environmental quality and lower economic activity, the introduction of sustainable agricultural enhancements, eco-tourism, and renewable energy initiatives is recommended. Cluster 2, marked by higher economic outputs and moderate environmental conditions, would benefit from the implementation of smart urban planning, stricter environmental controls, and the adoption of clean technologies. Finally, Cluster 3, which includes highly urbanized areas with robust economic growth, requires expanded green infrastructure, improved sustainable urban practices, and enhanced public transportation systems. These recommendations aim to foster balanced economic growth while preserving environmental integrity across Indonesia’s diverse landscapes.

Can foreign demand shocks reduce the pollution emission intensity? Evidence from exporters in China

This paper investigates the impact of foreign demand shocks on emission intensity using data from Chinese manufacturing exporters. We construct a Bartik instrument for changes in foreign demand by incorporating firms' initial specialization patterns and the portion of foreign demand changes independent of fluctuations in China's exports. We observe a significantly negative effect of increased foreign demand shocks on SO2 emission intensity (emission intensity effect), yet the overall impact on firms' SO2 emissions is minimal and statistically insignificant. Our decomposition reveals that although positive foreign demand shocks lead to increased SO2 emissions through output growth (scale effect), this effect is largely counteracted by the negative emission intensity effect. Further analysis shows that the emission intensity effect can be attributed to firms' adoption of cleaner technologies and the reallocation of product sales towards those with lower emission intensities.

An assessment of the carbon emissions of China's ICT system from the demand and supply perspectives

Previous research has predominantly examined China's Information and Communication Technology (ICT) industry's carbon emissions through the lens of technological progress, overlooking impacts from both demand and supply perspectives. We employ a subsystem input-output model to analyze the total emissions of China's ICT industry from 2002 to 2020, decomposing them into direct, intra-sectoral, feedback, and spillover components from both perspectives. Our findings reveal that between 2002 and 2020, demand-driven emissions increased by 205.1 %, while supply-driven emissions surged by 496.4 %. From both demand and supply perspectives, the spillover component emerged as the dominant contributor from 2002 to 2020, particularly in 2020, accounting for more than 99 % of the total emissions. From a demand-driven perspective, we identify ICT manufacturing as the primary emissions source, contributing to over 66 % of the total emissions during the period and triggering significant spillover emissions in the power and heavy manufacturing sectors. Conversely, the supply-driven approach highlights ICT services as the major emitter, accounting for over 70 % of the total emissions between 2002 and 2020, with notable spillover effects observed in the transport sector. We highlight the significance of shaping consumption behaviors related to ICT manufacturing products and improving emissions efficiency in electricity and heavy manufacturing, both crucial intermediate inputs in ICT production, from a demand perspective. From a supply perspective, promoting the adoption of clean technologies among downstream users of ICT services could aid China's emissions mitigation efforts in the digital era.

Opportunities and Challenges Associated with the Uptake of Residential Clean Fuel Usage.

Almost 3 billion people worldwide use solid fuel for cooking and heating. This review examines (i) household energy practices and infrastructures and their influence on fuel usage in different contexts; (ii) barriers in adoption of household clean energy technologies and uses in diverse settings and population groups and (iii) potential air pollution exposure reduction in homes through using processed fuel. Population health burden from solid fuel combustion-derived particulate air pollution has been estimated in several low- and middle-income countries. However, such studies have not been carried out in high income countries (e.g., UK). Irrespective of the region, fuel prices are the most dominant factor influencing the choice of fuel. Laboratory studies suggest processed fuel - pellets and briquettes - reduce particulate matter emissions by 70-80% and can be a promising alternative. Adoption of clean fuels for domestic energy needs facilitates progress towards five of the UN Sustainable Development Goals (SDGs). There is evidence that a variety of factors, including cost savings, encourage and hinder such uptake. These factors include price fluctuations, expenses, and the usage of clean fuels. Due to their distinct development scenarios, more expansive policy frameworks, and political economies of energy, these determinants are localized in character and differ significantly amongst economies. Therefore, in order to create innovative plans for the adoption of clean fuel use, strategies centred on local settings must be developed while keeping broad socio-technical and socio-economic issues in mind. Solid fuel processing - pelletization and briquetting - have the potential to reach Liquefied Petroleum Gas (LPG)-like emissions, and could be a potential strategy to mitigate exposure to household air pollution.

Ultra-stable hollow nanotube conjugated microporous polymer incorporating fluorenyl moieties for Co-capture of PM and CO2

Conjugated microporous polymers have a highly delocalized π-π conjugated porous skeleton connected by covalent bonds, which can combine their excellent stability with high adsorption, in order to be applied to the study of co-capture of harmful particulate matter (PM) and carbon dioxide (CO2) under high temperature and high humidity conditions. In this paper, fluorene-based coupled conjugated microporous polymers (D-CMPs) with functionalized hollow nanotubes and abundant microporous structures were proposed. Through mechanism exploration and molecular electrostatic potential (MESP) calculation, the capture efficiency, adsorption capacity and selectivity of PM and CO2 in the waste gas stream of carbon-based combustion were analyzed. The results indicate that D-CMPs, with their rigid carbon-based π-conjugated framework, exhibit excellent tolerance under prolonged high-humidity conditions, with a capture efficiency exceeding 99.87% for PM0.3 and exceeding 99.99% for PM2.5. Meanwhile, based on its chemical/thermal stability, it can realize the recycling of adsorption-regeneration. On this basis, the "slip effect" induced by the open three-dimensional hierarchical porous structure of D-CMPs significantly enhances airflow dispersion and improves gas throughput (with a minimal permeation resistance of only 15 Pa). At a pressure of 1 bar and a temperature of 273.15 K, D-CMP-2 exhibited a CO2 adsorption capacity of up to 2.69 mmol g−1. The fitting results of three isothermal adsorption models demonstrate that D-CMPs exhibit an outstanding equilibrium selectivity towards CO2. Therefore, prior to the widespread adoption of low-carbon and clean energy technologies, porous solid materials exhibiting excellent structural stability, equilibrium selectivity, environmental tolerance, and high adsorption capacity emerge as optimal candidates for the treatment of industrial waste gases.

Net-zero energy transition in ASEAN countries: The evolutionary model brings novel perspectives to the cooperative mechanism of climate governance

In an era marked by escalating climate change, the fragile ecological balance faces increasing strain. Whilst significant knowledge exists regarding the accumulation of carbon emission within the Association of Southeast Asian Nations, little is known about when and how countries could reach net-zero emission goal as agreed in Paris Agreement. For this purpose, our study examines the primary driving factors of carbon emission from 1990 to 2020 across the ten countries using the Logarithmic Mean Divisia Index model. We leverage the random forest model to explore the net-zero scenarios and the Autoregressive Integrated Moving Average approach to identify the evolutionary trajectories of carbon emission trends. Our findings underscore the imperative need for expediting decarbonization efforts, emphasizing the urgency for widespread adoption of clean technologies and substantial investment in green initiatives. Countries at similar stages of progress might establish a cooperation mechanism of clean energy base construction, energy storage allocation and policy formulation. These insights can help us better estimate future demand of clean energy, explore strategies for decarbonization, and inform historical commonalities of carbon emission growth.

Policy Analysis on Clean Cooking in Malawi: Case of Improved Cookstoves

Transition from cooking with traditional biomass to clean cooking is a persistent challenge in Malawi. The underlying technologies in clean cooking are improved cookstove. Improved cook stoves are designed to reduce fuel consumption per meal and to curb smoke emissions experienced in traditional three-stone cookstove. However, promotion adoption and utilisation of clean cooking requires coordinated policy and regulatory framework. This study analysed the Malawi policy regulatory framework on clean cooking by benchmarking with relevant literature. The following policy gaps were identified: (i) the lack of clear cookstove rating by Malawi Bureau of Standards; (ii) uncomplimentary policies and regulations in the energy and forestry sectors on clean cooking fuels and technologies; (iii) the lack of empirical data on adoption and utilisation of clean cooking technologies and fuels in Malawi; (iv) predicaments in adopting and using international standards for testing cookstoves; and (v) the value chain of improved cookstoves and other forms of clean cooking fuels and technologies that is not adequately analysed. Coordinated development and harmonious implementation of clean cooking regulations in the key sectors of energy and forestry can promote adoption and utilisation of clean cooking methods and technologies in Malawi.

Resources, innovation, globalization, and green growth: The BRICS financial development strategy

Resources, innovation, globalization, and green growth are interconnected pillars that shape societies and economies. By effectively managing resources, fostering innovation, embracing globalization, and embracing green growth, countries can achieve sustainable development, economic prosperity, and a better future for future generations. In this paper, we examine the nexus of natural resources, innovation, globalization, and green growth in BRICS countries from 1990 to 2021 in light of financial development's role in promoting green growth. We use dynamic system panel data estimations and robust random effect GLS regression for long-run estimates. BRICS countries experience green growth due to natural resources, globalization, financial development, and research and development. There is a negative relationship between globalization and green growth in the BRICS countries. Policymakers need to consider the policy implications discussed in this document to ensure a greener and more sustainable future for the BRICS countries. To mitigate the negative impacts of globalization on green growth, BRICS countries should enhance their environmental regulations. Stricter standards can help control pollution, promote sustainable resource management, and encourage the adoption of clean technologies. The BRICS countries should prioritize sustainable trade practices by integrating environmental considerations into trade agreements and policies. This could include promoting eco-labeling, supporting eco-friendly supply chains, and reducing trade barriers for environmentally friendly products.

Techno-economic Analysis of a Solid Fuel Testing Facility for Thermal Power Plants in Peninsular Malaysia: A Monte Carlo Approach

Coal-fired thermal power plants in Peninsular Malaysia are expected to remain operational for at least another 20 years, highlighting the need for clean coal technology adoption. The introduction of new coal types necessitates the verification of their technical viability prior to adoption into power plants, which is addressed by the proposed Solid Fuel Testing Facility (SFTF) system. Hence, this study developed a Monte Carlo-based model to examine the economic factors influencing the profitability of the SFTF system as a solid fuel pre-qualification assessment tool. Three critical factors have been identified as contributors to the SFTF system's economic viability uncertainty: the Test Number, Power Purchase Agreements (PPA) Reduction, and Test Cost. In terms of Net Present Value (NPV) valuation, the Test Number has the highest sensitivity. The projected increase in coal demand necessitating the inclusion of a broader spectrum of new coal variants in power plant operations. As a result, the possibility of an expanded Test Number for the SFTF system exists until the PPA's tenure expires. Therefore, the possibility of favourable NPV outcomes remains prominent throughout the term of the PPA. In contrast, the PPA Reduction has the lowest susceptibility to NPV sensitivity. This demonstrates the SFTF system's ability to navigate policy shifts related to PPA tenure reductions, albeit within a range of 3 to 4 years of reduction. It is suggested that a broader range of parameters be considered in order to gain a more holistic understanding of the economic viability of the proposed SFTF system.

PRICES, POLITICS AND PERSUASION: THE CASE OF POLLUTION CONTROL AND CLEAN TECHNOLOGY ADOPTION

This paper presents three simple models to study how prices, politics and persuasion may each play a role in environmental policy-making. Our conclusions are twofold. First, in the absence of increasing returns, requiring the polluting industry to purchase pollution permits can internalize the negative externality of pollution, and the optimal price of pollution permits should increase with the disutility of pollution. Second, with increasing returns in the industry using clean technologies, it is welfare enhancing to complement the pollution permits policy with a tax-funded subsidy to the clean industry, or with a tax-funded public campaign to persuade consumers to move away from pollution-generating goods.
