Company carbon disclosures are a fundamental piece of information for assessing firms’ environmental impact, and many policy actions are associated with them. Responding to a rising demand for transparency and regulatory requirements, firms disclose information on their greenhouse-gas (GHG) emissions and voluntarily engage with external assurance of the reported data. However, the possible existence of systematic differences in reported emissions with respect to their assurance status is under-explored. This study investigates the causal effect of external assurance on carbon disclosures in a sample of European companies. Findings suggest that, on average, non-assuring firms under-report their direct GHG emissions by a share similar to the largest annual emissions reduction in the EU, compared to the assured reports of their peers. Instead, assurance’s effect is much weaker in indirect emissions. These results demonstrate that third-party assurance could provide more prudent estimates of corporate GHG emissions which are important for all stakeholders, including companies, investors and policymakers, to mitigate climate change.
公司碳信息披露是评估公司环境影响的基本信息,许多政策行动都与之相关。为响应日益增长的透明度需求和监管要求,企业披露其温室气体(GHG)排放信息,并自愿参与报告数据的外部保证。但是,报告的排放量与它们的保证状况之间是否可能存在系统性差异,尚未得到充分探讨。本研究以欧洲公司为样本,探讨外部保证对碳披露的因果效应。研究结果表明,平均而言,与同行的有保证的报告相比,无保证的公司少报其直接温室气体排放量的比例与欧盟最大的年度减排量相似。相反,保险对间接排放的影响要弱得多。这些结果表明,第三方担保可以提供更谨慎的企业温室气体排放估计,这对包括公司、投资者和政策制定者在内的所有利益相关者都很重要,有助于减缓气候变化。

Fintech plays an instrumental role in advancing global ESG objectives, leveraging a more inclusive, transparent, and accountable financial system. Our paper explores the occurrence of dynamic linkages between Fintech and ESG across various dimensions, examining how the strength of their interconnectedness drives the energy transition towards clean technology. Using daily data from 31st May 2018 to 1st August 2024, we apply a time-varying parameter robust Granger causality method coupled with quantile technique to provide the first attempt in the literature on the dynamic causal patterns between the strength of Fintech-ESG connection and Cleantech energy transition risk (CETR). We find asymmetry in the connectedness across different quantiles, with Fintech sectors acting primarily as shock transmitters, while most ESG indexes are receivers. The 2022 Russia-Ukraine conflict reduces the connectedness between Fintech and ESG, with minimal effects on spillover direction. Our results show a heterogeneous response to shocks in developed markets, while developing ones tend to react more homogeneously. Additionally, we find strong evidence of a time-varying causal relationship between Fintech-ESG connectedness and CETR, with the conflict exacerbating asymmetry, especially at the lower quantile. Recent trends suggest a modest resurgence in this connection, signalling a re-emergence of the Fintech-ESG connection influence on CETR. The impact of extreme events tends to taper-off over time, suggesting that the prolonged conflict-driven market environment may have stabilized sufficiently to restore Fintech's role in promoting ESG initiatives, thereby supporting the ongoing transition to clean technology.
金融科技在推进全球ESG目标、推动建立更加包容、透明和负责任的金融体系方面发挥着重要作用。我们的论文探讨了金融科技和ESG之间在各个维度上的动态联系,研究了它们相互联系的强度如何推动能源向清洁技术的过渡。利用2018年5月31日至2024年8月1日的日常数据,我们采用时变参数鲁棒格兰杰因果关系方法结合分位数技术,首次在文献中尝试了金融科技- esg连接强度与清洁技术能源转型风险(CETR)之间的动态因果关系模式。我们发现不同分位数之间的连通性不对称,金融科技行业主要充当冲击发射器,而大多数ESG指数都是接收器。2022年俄罗斯-乌克兰冲突降低了金融科技与ESG之间的联系,对溢出方向的影响微乎其微。我们的研究结果显示,发达市场对冲击的反应各不相同,而发展中市场的反应往往更为均匀。此外,我们发现强有力的证据表明,金融科技- esg连通性与ccr之间存在时变因果关系,这种冲突加剧了不对称性,尤其是在较低的分位数。最近的趋势表明,这一联系略有复苏,标志着金融科技- esg联系对ctr的影响再次出现。随着时间的推移,极端事件的影响往往会逐渐减弱,这表明长期冲突驱动的市场环境可能已经足够稳定,可以恢复金融科技在促进ESG倡议方面的作用,从而支持正在进行的向清洁技术的过渡。

This paper first distinguishes green innovation into substantive innovation (GI) and strategic innovation (SI). It then employs evolutionary game and panel econometric models to examine firms' green innovation choices under varying intensities of carbon emission regulation, as well as the moderating role of green finance support. The results show that carbon regulation mitigates the insufficient incentive problem for green innovation. However, different levels of regulatory intensity induce firms to adopt distinct green innovation strategies. Using the comprehensive carbon price (TCP) as a proxy for regulation intensity, we identify an inverted U-shaped relationship between TCP and GI. When the TCP is below the critical value of 19.08 yuan/ton, an increase in carbon price effectively promotes GI, whereas beyond this threshold, further increases significantly inhibit GI. In contrast, TCP exhibits a significant positive linear relationship with SI, indicating that for each one-yuan increase in carbon price raises strategic green innovations by approximately 0.76 %. Green finance support alleviates the cost and risk pressures imposed by carbon emission regulation, raising the threshold to 20.56 yuan/ton and playing a significant moderating role. Moreover, heterogeneity analysis reveals that the inverted U-shaped relationship between TCP and GI varies across firms: the threshold shifts rightward for large-scale firms and those facing intense industry competition, but leftward for heavily polluting firms. These findings provide policy implications for optimizing carbon regulation and green finance mechanisms, and for addressing firms' overemphasis on the quantity rather than quality of green innovation.
本文首先将绿色创新分为实质性创新(GI)和战略性创新(SI)。运用演化博弈模型和面板计量经济模型考察了不同碳排放监管强度下企业的绿色创新选择,以及绿色金融支持的调节作用。研究结果表明,碳调控缓解了绿色创新激励不足的问题。然而,不同的监管强度会促使企业采取不同的绿色创新策略。利用综合碳价格(TCP)作为监管强度的代表,我们发现TCP与GI之间存在倒u型关系。当TCP低于19.08元/吨临界值时,碳价的上涨有效促进了GI,而超过该临界值后,进一步上涨则显著抑制GI。相比之下,TCP与SI表现出显著的正线性关系,表明碳价格每增加1元,战略绿色创新就会增加约0.76%。绿色金融支持缓解了碳排放监管带来的成本和风险压力,将碳排放监管门槛提高到20.56元/吨,起到了显著的调节作用。此外,异质性分析表明,TCP和GI之间的倒u型关系在不同企业之间存在差异:大型企业和面临激烈行业竞争的企业的阈值向右移动,而重污染企业的阈值向左移动。这些发现为优化碳监管和绿色金融机制,以及解决企业过度强调绿色创新的数量而不是质量的问题提供了政策启示。

Hydrogen is likely to play an important role in achieving China's carbon neutrality target which is crucial for coping with the global climate change. Given that different regions of China are heterogeneous in terms of resources and demand, this study developed a provincial-level China energy system optimization model that considers ultra-high voltage (UHV) electricity transmission and hydrogen pipeline transmission among provinces. With the model, we evaluated the optimal deployment of hydrogen in China under two paths to be carbon-neutral: a relatively loose path for the 2 °C Global Temperature Target and a relatively tight path for the 1.5 °C Global Temperature Target. This study found that the tight path indicates a faster substitution of blue and green hydrogen for gray hydrogen, which is associated with the relocation of hydrogen production from coal-rich provinces to renewable-rich ones. Compared with the loose path, the tight path would require approximately 100 %–120 % higher annual investment in China from 2025 to 2035. This study also revealed that both the paths would increase the inter-provincial carbon emission transfer from developed to less-developed provinces. A policy implication is that China should consider implementing carbon accounting at the demand side, which would be vital for an equitable regional development.
氢可能在实现中国碳中和目标方面发挥重要作用,这对应对全球气候变化至关重要。针对中国不同地区在资源和需求上的异质性,本研究建立了考虑省际特高压输电和管道输氢的中国省级能源系统优化模型。利用该模型,我们评估了中国在两种碳中和路径下的最佳氢部署:相对宽松的2°C全球温度目标路径和相对紧凑的1.5°C全球温度目标路径。该研究发现,紧密路径表明蓝色和绿色氢更快地取代灰色氢,这与氢气生产从煤炭丰富的省份转移到可再生能源丰富的省份有关。与宽松路径相比,从2025年到2035年,紧缩路径将要求中国每年的投资增加约100% - 120%。研究还发现,这两种路径都增加了发达省份向欠发达省份的省际碳排放转移。一个政策暗示是,中国应该考虑在需求侧实施碳核算,这对公平的区域发展至关重要。

Does residential electricity demand respond to prices? Using a large, high-frequency smart meter dataset from Denmark combined with hourly prices, we estimate the short-run, hourly price elasticity of electricity demand at the household level. Although most households show no significant responsiveness to price signals, we find that nearly one third reduce their consumption significantly when prices rise. On average, a one Danish krone increase in electricity prices leads to a 2.6% decrease in demand. By linking smart meter data to administrative records, we further examine how price responsiveness varies across socio-demographic groups. We find that the price sensitivity is higher among households with higher educational attainment and overall electricity consumption, but lower among those aged 35 to 54.
居民用电需求对电价有反应吗?使用丹麦的大型高频智能电表数据集,结合小时价格,我们估计了家庭层面电力需求的短期小时价格弹性。尽管大多数家庭对价格信号没有明显的反应,但我们发现,当价格上涨时,近三分之一的家庭显著减少了消费。平均而言,每增加一个丹麦克朗的电价就会导致需求下降2.6%。通过将智能电表数据与管理记录联系起来,我们进一步研究了不同社会人口群体对价格的反应如何变化。我们发现,受教育程度和整体用电量较高的家庭对价格的敏感度较高,而年龄在35至54岁之间的家庭对价格的敏感度较低。

This study investigates the impact of the U.S. climate policy uncertainty (CPU) on the green innovation output of firms, with a particular focus on Chinese A-share listed companies from 2009 to 2020. The findings reveal that the U.S. CPU can act as a catalyst for enhancing green innovation among Chinese firms. The heterogeneity analysis reveals that the U.S. CPU significantly influences green innovation in state-owned firms and heavy-polluting firms, firms with ownership by more institutional investors, and firms that are either in a growth or in a decline phase. Further mechanism analysis indicates that the increasing U.S. CPU enhances firms' green innovation outcomes via three channels: mitigating corporate financial distress risk, increasing government subsidies, and altering the competitive landscape. In addition, firms' climate risk exposure amplifies the effect of CPU, whereas proactive government climate policies tend to weaken it. Our research findings provide substantial insights for investors and governmental agencies in comprehending the effects of cross-border spillover from climate policies on firm innovation.
本研究考察了美国气候政策不确定性(CPU)对企业绿色创新产出的影响,并以2009 - 2020年中国a股上市公司为研究对象。研究结果表明,美国中央处理器可以作为促进中国企业绿色创新的催化剂。异质性分析表明,美国中央资本对国有企业和重污染企业、机构投资者持股较多的企业以及处于成长期和衰退期的企业的绿色创新具有显著影响。进一步的机制分析表明,美国CPU的增加通过缓解企业财务困境风险、增加政府补贴和改变竞争格局三个渠道提高了企业的绿色创新成果。此外,企业的气候风险暴露放大了CPU的效应,而积极的政府气候政策往往会削弱CPU的效应。我们的研究结果为投资者和政府机构理解气候政策跨境溢出对企业创新的影响提供了重要见解。

The theory of storage in a power system with stochastic demand 具有随机需求的电力系统的存储理论

Electric power systems are increasingly turning to energy storage systems to balance supply and demand. But how much storage is required? What is the optimal volume of storage in a power system and on what does it depend? In addition, what form of hedge contracts do storage facilities require? We answer these questions in the special case in which the uncertainty in the power system involves successive draws of an independent, identically-distributed random variable. We characterise the conditions for the optimal operation of, and investment in, storage and show how these conditions can be understood graphically using price-duration curves. We also characterise the optimal hedge contracts for storage units.
电力系统越来越多地转向储能系统来平衡供需。但是需要多大的存储空间呢?电力系统的最佳存储容量是多少?它取决于什么?此外,仓储设施需要哪种形式的对冲合约?我们在电力系统的不确定性涉及一个独立的、同分布的随机变量的连续抽取的特殊情况下回答这些问题。我们描述了存储的最佳运行和投资条件,并展示了如何使用价格-持续时间曲线以图形方式理解这些条件。我们还描述了存储单元的最佳对冲合约。

Countries can rely upon decarbonization policies that stimulate the green transition of energy systems to combat global warming. However, such policies can provide financial opportunities to local firms as they lead to changes in the performance of the national energy system. Using a sample composed of 5936 nonfinancial listed firms operating in 42 developing countries over the period 2015–2024, our study investigates how the decarbonization strategies of local authorities affect corporate financial performance. Panel regressions reveal that a more diversified network of energy suppliers contributes to an increase in the financial performance of firms from Southeast Asia and Latin America. Strengthening the decarbonization regulations and the political commitment to energy transition policies leads to high corporate performance in the region of Sub-Saharan Africa. Estimates also pointed out that listed firms from Middle East and North Africa can financially benefit from investments in energy system infrastructure. Interestingly, the mechanisms that could explain the positive effects of such decarbonization policies include reducing operational costs and enhancing firms' capacity to repay their debts.
各国可以依靠刺激能源系统绿色转型的脱碳政策来应对全球变暖。然而,这些政策可以为当地公司提供财政机会,因为它们导致国家能源系统业绩的变化。本文以2015-2024年间在42个发展中国家运营的5936家非金融类上市公司为样本,考察了地方政府的脱碳策略对企业财务绩效的影响。面板回归显示,更多元化的能源供应商网络有助于东南亚和拉丁美洲公司财务绩效的提高。加强脱碳法规和对能源转型政策的政治承诺将导致撒哈拉以南非洲地区的高企业绩效。估计还指出,中东和北非的上市公司可以从能源系统基础设施的投资中获得财务收益。有趣的是,可以解释这种脱碳政策的积极影响的机制包括降低运营成本和提高企业偿还债务的能力。
