As China pursues carbon peak and carbon neutrality goals, the low-carbon economy and energy conservation have become essential components of high-quality economic development. Although agriculture plays a fundamental role in a country, the relationship between agricultural development, investment, and carbon emissions is often overlooked in existing research. This study aims to address this gap by examining the impact of financial investment in agriculture on carbon dioxide emissions and the underlying mechanisms driving this relationship. Employing panel data from mainland China's provinces between 2007 and 2020, the study also investigates the regional heterogeneity in the effect of agricultural investment on carbon dioxide emissions. Our findings reveal that increasing financial investment in agriculture effectively reduces carbon dioxide emissions, primarily through optimizing industrial structure and fostering technological innovation. Heterogeneity tests indicate that the inhibitory effect of agricultural investment on carbon dioxide emissions is more pronounced in eastern regions, provinces with a higher degree of marketization, and provinces with a substantial proportion of primary industry. These results provide a theoretical basis for leveraging agricultural financial investment to restrain carbon dioxide emissions and highlight the unique contributions of our study to the existing body of research. 相似文献

This study explores the impact of natural resource exploitation, trade openness, and economic growth on carbon emissions in a sample of oil-exporting nations for the period 1971–2014. To examine this relationship, we used the panel autoregressive distributed lag model and a set of econometric techniques accounting for cross-sectional dependence. Our results indicate that the exploitation of natural resources and trade openness have a long-term negative impact on environmental quality. Furthermore, our analysis confirms the validity of the Kuznets Environmental Curve for oil-exporting countries. An assessment of causality reveals a bidirectional link between natural resources, economic growth, and CO2 emissions, as well as a unidirectional link between trade openness and CO2 emissions. In the light of our findings, appropriate policies could include the imposition of more stringent regulations on the exploitation of natural resources, the application of taxes on carbon emissions, and the promotion of clean and renewable technologies. Greater international cooperation is also needed to address these environmental issues on a global scale. 相似文献

人类活动排放的大量温室气体已经造成多种不利影响,为缓解这些不利影响,已有多个国家提出了碳中和目标。碳中和评估与预测预估是实现碳中和目标的科学基础,准确估算碳排放量和碳去除量是进行碳中和评估的关键,可以帮助决策者制定减排和增汇政策。本文梳理了碳排放量和碳去除量的估算方法以及预测预估方法的原理和特点,以期为准确评估碳中和现状以及预测预估未来情景下实现碳中和目标的可能性和路径提供方法论参考。碳排放量的估算方法可以分为用于支撑碳交易市场的碳排放核算方法、面向消费侧碳排放的估算方法和基于因素分解法的碳排放计量方法三大类;前两类方法主要用于历史碳排放量的盘点,第三类方法可用于碳排放量的预估。陆地生态系统碳去除量估算方法可以分为统计模型法、机理模型法和遥感模型法三大类;第一类方法应用最早但估算结果较粗糙,第二类方法模型应用最多但估算结果存在较大的不确定性,第三类方法观测范围大但缺乏预测预估能力。近年来,模型分析法在碳中和评估和预测预估上得到越来越广泛的应用。 相似文献

The present study inspects the relationships between the carbon dioxide (CO2) emissions, real GDP, renewable and non-renewable energy consumption, as well as the service growth for top ten countries (TTC) in service activities. The empirical modeling used in the study involves the procedures of cointegration and tests of Granger causality to inspect the dynamic interaction between the variables during the period from 1980 to 2018. The results of the present study suggest that the variables are cross-sectionally dependent. In addition, the variables appear to be cointegrated based on several tests. The long-run outcomes revealed an inversed U-shaped form between emissions-GDP proving the validity of the environmental Kuznets curve assumption. The fully modified ordinary least squares and dynamic OLS estimates show that the non-renewable energy and economic growth contribute to the increase of CO2 emissions, while service value-added leads to decrease emissions. Furthermore, the renewable energy coefficient comes through as negative but insignificant for the selected panel. The TTC in service should stimulate the usage of renewable energy in various service events for following the path of sustainable development. Devising the investment plans associated with the use of renewable energies is quite essential for the advancement of the service sector leading to mitigating emissions portion. 相似文献

Sustainable growth and the reduction of environmental pressures are important priorities that are issues of concern for both developed and developing countries. However, while carbon emissions and ecological footprint are commonly used by researchers in the context of environmental deterioration, a broader and more extensive metric for ecological quality is considered necessary. From this perspective, the load capacity factor provides a more detailed sustainable environment appraisal by simultaneously considering biocapacity and ecological footprint. Limited studies have examined the determinants of load capacity factor (LCAP). This survey attempts to fill the gap, using the case of Japan. Employing the dynamic ARDL approaches, the present research investigates the effect of renewable energy usage, economic growth, economic complexity, financial development, and trade globalization on load capacity factor in Japan for the period between 1980 and 2017. The empirical evidence indicates that economic complexity, economic growth, and financial development adversely impact LCAP, whereas renewable energy usage and trade globalization positively affect LCAP. Hence, we recommend that it is essential for Japan to attain self-sufficiency in essential goods and minimize its reliance on the rest of the world. Furthermore, policymakers should capitalize on the benefits of trade globalization by adopting additional measures aimed at facilitating trade liberalization. 相似文献

有关清洁电力是否有效降低二氧化碳排放,有两种不同观点,本文分析了产生争议的原因,并基于机理分析,选取1998—2018年中国30个省份的相关数据,利用空间面板杜宾模型研究清洁电力发展对区域二氧化碳排放的影响。回归结果显示:(1)二氧化碳排放在省域之间具有显著的正向空间溢出效应。(2)清洁电力发展与二氧化碳排放之间呈倒U形关系并通过了一系列稳健性检验。(3)进一步地通过效应分解发现,清洁电力发展无论是直接效应还是间接效应,均需要达到一定的门槛值之后才会对区域二氧化碳排放产生促减效用。最后,通过中介效应模型检验发现,清洁电力发展带来的能源消费结构调整和能源利用效率改变是影响二氧化碳排放的作用机制。 相似文献

This study explores the impact of research and development (R&D) investment and financial development on environmental degradation measured by carbon emissions (CO2), and energy use along with some other variables in a panel of 12 Asian economies using balanced panel data from 1997 to 2020. The empirical estimates of and dynamic ordinary least squares reveal that spending, financial development, and globalization lower environmental degradation by reducing emissions. In contrast, economic growth, energy use, population, and industrialization increase environmental degradation (Model 1). Moreover, economic growth, R&D spending, financial development, environmental degradation, and industrialization have a positive direct effect on energy use, whereas population and globalization have an inverse relationship with energy use (Model 2). These empirical findings recommend that the management authorities of Asian economies need to develop thoughtful action plans to achieve a balance between economic growth, financial and industrial development, and the accomplishment of sustainable development goals by reducing carbon emissions and sustaining energy consumption. 相似文献

Complex relationships exist between programs to reduce carbon dioxide (CO2) from the electricity sector and programs to promote renewable electricity generation. Simulation modeling of three scenarios in the UK electricity sector are used to identify potential interactions between these programs. A strict CO2 cap can result in a renewable electricity requirement being easily met. Conversely, the renewables quota could be required under low natural gas prices to keep electricity suppliers from switching from coal to gas. Similarly, CO2 trading can reduce renewables deployment levels because purchased CO2 allowances replace renewables. Therefore, both programs are required to ensure CO2 and renewables goals. The planning implications for administrative procedures and renewables subsidies are also discussed. 相似文献

The objective of this paper is to compare the carbon emissions produced as a result of product consumption by the residents of an Irish city-region, that is Limerick City and its environs. The resulting carbon footprints are used to compare imports of food items, manufactured products and construction materials with domestic production as well as changes between 1996 and 2002. The total ecological footprints (EF) associated with product consumption are also calculated by aggregating the theoretical land required to sequester carbon emissions and the terrestrial land area appropriated for agricultural production and industrial activity. It is suggested that this approach be used to allocate producer or consumer responsibility for environmental impacts from trade. 相似文献

在全球碳中和的新形势下,欧盟委员会于2021年7月正式提出“碳边境调节机制”(CBAM)立法提案,并计划于2023年起实施。本文在总结立法提案关键要素的基础上,着重分析欧盟CBAM的合法性与合理性,研判可能对我国产生的潜在影响,并从国际国内层面提出对策建议。分析发现,欧盟采取“名义”碳市场的形式,初期将覆盖水泥、电力、化肥、钢铁和铝等5个行业,只核算产品生产过程的直接排放,暂不考虑间接排放,2023—2025年是过渡期,2026年开始正式实施。欧盟CBAM的合法性与合理性面临诸多挑战:不符合世界贸易组织国民待遇原则和最惠国待遇原则,但存在满足关税与贸易总协定例外条款的可能性;违反国际气候治理的共同但有区别的责任原则、公平原则和各自能力原则,也不符合公约关于国际贸易歧视或变相限制的条款;对解决碳泄漏问题和保护本土竞争力的作用有限;产品隐含碳核算和碳价确定是技术难点问题。影响评估发现,欧盟CBAM将使我国受影响部门的对欧出口总额降低11%~13%,出口成本增加1亿~3.05亿美元,其中约四分之三的成本将由钢铁行业承担,对贸易隐含碳的下降作用有待进一步考量;此外,欧盟CBAM将会影响多边国际... 相似文献

The aim of this article is to identify and estimate different inventories of emissions during construction activities. A unique approach for simulating construction materials and their stochastic embodied greenhouse gas (GHG) emissions is proposed. The % of carbon released by various equipment and materials with respect to construction activities was also measured to assess emissions inventory supported by construction project case example. Finding shows that the gross carbon emissions from construction materials was 5419.576 ton of CO2 whereas carbon emissions from sustainable construction materials was 752.383 ton of CO2. The findings of the study, which revealed a significant potential for an 86.19% reduction in carbon emissions by utilizing substitute substances in construction materials compared to conventional materials, have led to the proposal of important measures. These measures are crucial for identifying the primary sources of carbon emissions in construction activity and play a pivotal role in promoting sustainable construction practices and achieving green ratings for construction projects. The research will help sustainable construction & will pave the way for achieving an effective green rating for construction projects. 相似文献

全面系统地评估排污权交易和碳排放权交易的减污降碳协同效应,对于进一步发挥应对气候变化和大气污染治理的协同效应、推进全国统一生态环境市场建设具有重要意义。本文基于污染治理和政策管理的双重视角,采用多时点双重差分和倾向得分匹配,分别检验排污权交易和碳排放权交易的减污和降碳效应;并在此基础上,研究三种政策情景下(排污权交易、碳排放权交易以及组合政策)的协同减排效应差异。研究表明,从污染治理视角,排污权交易和碳排放权交易均显著降低了二氧化硫和二氧化碳排放量,实现了减污降碳的协同效应;从政策协同管理视角,在减少二氧化硫污染方面,组合政策比各类政策的单独实施更为有效;在降低二氧化碳排放方面,碳排放权交易比排污权交易和组合政策更为有效。因此,在推进气候变化应对和大气污染治理机制融合的进程中,应有所侧重地推进碳排放权交易和排污权交易组合使用。 相似文献

This paper presents a review of energy use in 22 selected countries of Asia and estimates the anthropogenic emission of sulphur dioxide (SO2) for the selected countries, both at national and disaggregated sub-country regional levels. The paper also makes a comparative assessment of the Asian countries in terms of SO2emission intensity (i.e. emission per GDP), emission per capita and emission density (i.e. emission per unit area). Total SO2emission in the region was estimated to be about 38 million tons in 1990. Five countries, China, India, South Korea, Japan and Thailand, accounted for over 91% of the regional SO2emission. Coal use had the dominant share (81%) of the total emission from the region. Among the economic sectors, industry contributed the largest share (49%) to the total emissions of the selected countries as a whole, followed by the power sector (30%). These findings suggest the need for mitigation strategies focussed on the industry and power sectors of the major emitting countries in Asia. 相似文献

Although numerous empirical studies have scrutinized the impact of technological innovation, renewable energy, and natural resources on carbon emissions (CCO2), there is a lack of empirical knowledge of consumption-based CCO2 emissions. This study examines the impacts of technological innovation, renewable energy, and natural resources factors on CCO2 emissions in China. In addition, the present work considers the role of the banking sector in environmental neutrality in China from 1990 to 2019. For this purpose, the sophisticated approach of “bootstrap autoregressive distributed lag (BARDL)” is applied to explore the association of the selected indicators on CCO2. The outcomes indicate that (i) economic growth and natural resources negatively impact environmental neutrality; (ii) environment-related technologies and renewable energy are crucial to promoting environmental neutrality; and (iii) banking sector in China has a positive association with CCO2 emissions. The findings of this work recommend using effective measures to mitigate ecological pollution by using green energy sources and strengthening the banking sector by offering environment-friendly investment loans. Likewise, strategies should be designed that reinforce sustainable development. 相似文献

Green credit policy is designed to address the global climate risk. However, few studies have investigated empirically whether green credit policy indeed reduces corporate carbon emission intensity. Based on firm-level data in China and a difference-in-differences model, this study explores how corporate carbon emission intensity evolves following the green credit policy. We find that, on the whole, the green credit can effectively reduce corporate carbon emission intensity, while the dynamic negative effect tends to alleviate after 2017. Specifically, green credit reduces corporate carbon emission intensity mainly through lowering investment carbon intensity and enhancing environmental supervision. However, the signaling mechanism of green credit does not significantly alleviate corporate carbon emission intensity. The green credit has a stronger reduction effect on corporate carbon emission intensity with third-party certification, non-state-owned ownership, and high financing constraint. We thereby suggest that innovations should be made to the standards and processes of green credit to ensure sustainability and stability. Quantitative and standardized corporate environmental information disclosure is essential for the low-carbon effect on green finance innovation. 相似文献
