    越来越多的科学文献强调需要推进当前的环境风险评估(ERA)方法和相关的监管框架,以更好地解决农药使用对生物多样性和生态系统的景观规模和长期影响。此外,需要更多的协作和综合方法来实现可持续发展目标。欧洲食品安全局(EFSA)越来越多地采用“一个健康”方法来支持向更安全的过渡,更健康、更可持续的食物。为此,EFSA委托制定行动路线图,以建立下一代欧洲伙伴关系,基于系统的环境风险评估(PERA)。这里,我们总结了2022年PERA路线图中报告的主要结论和建议。这个路线图强调了数据的碎片化,管理部门的知识和专业知识导致流程欠佳,并阻碍了更好地保护环境所需的综合ERA方法的实施。为了推进ERA,我们重新审视了当前ERA范式的基本假设;化学品风险通常是通过逐项物质隔离评估和管理的,现实的最坏情况和分层方法。我们建议优化使用农药作为试点领域的大量信息和专业知识。建议尽快采取以系统为基础的办法,即在当前的监管框架内,以激发朝着生态和社会相关性的系统层面构建的ERA的逐步过渡。有形的基于系统和综合步骤是可用的。例如,农药前瞻性和回顾性ERA的现有数据来源丰富,可用于现实基准现有和新的ERA方法。为了实现这些目标,必须加强科学学科和监管部门利益相关者之间的合作。
    A growing body of scientific literature stresses the need to advance current environmental risk assessment (ERA) methodologies and associated regulatory frameworks to better address the landscape-scale and long-term impact of pesticide use on biodiversity and the ecosystem. Moreover, more collaborative and integrative approaches are needed to meet sustainability goals. The One Health approach is increasingly applied by the European Food Safety Authority (EFSA) to support the transition towards safer, healthier and more sustainable food. To this end, EFSA commissioned the development of a roadmap for action to establish a European Partnership for next-generation, systems-based Environmental Risk Assessment (PERA). Here, we summarise the main conclusions and recommendations reported in the 2022 PERA Roadmap. This roadmap highlights that fragmentation of data, knowledge and expertise across regulatory sectors results in suboptimal processes and hinders the implementation of integrative ERA approaches needed to better protect the environment. To advance ERA, we revisited the underlying assumptions of the current ERA paradigm; that chemical risks are generally assessed and managed in isolation with a substance-by-substance, realistic worst-case and tiered approach. We suggest optimising the use of the vast amount of information and expertise available with pesticides as a pilot area. It is recommended to as soon as possible adopt a systems-based approach, i.e. within the current regulatory framework, to spark a step-wise transition towards an ERA framed at a system level of ecological and societal relevance. Tangible systems-based and integrative steps are available. For instance, the rich sources of existing data for prospective and retrospective ERA of pesticides could be used to reality-benchmark existing and new ERA methods. To achieve these goals, collaboration among stakeholders across scientific disciplines and regulatory sectors must be strengthened.

    一方面,经济,特别是发展中的,需要成长。另一方面,气候变化是全球最紧迫的问题,各国应采取必要的措施。如此复杂的任务需要新的理论和经验模型来捕捉这种复杂性并提供新的见解。我们的研究使用了新开发的理论框架,该框架涉及可再生能源消费(REC)和全要素生产率(TFP)以及传统的二氧化碳排放因素。与传统模型相比,它为决策者提供了边界信息,例如环境库兹涅茨曲线(EKC),仅限于收入和人口。还采用了先进的面板时间序列方法,解决小组数据问题,同时不仅产生汇集的结果,而且产生针对特定国家的结果。本研究考虑了20个可再生能源国家吸引力指数(RECAI)国家。结果表明,REC,TFP,和出口减少了二氧化碳排放量,弹性分别为0.3、0.4和0.3。相反,收入和进口增加了排放量,弹性分别为0.8和0.3。此外,我们表明,RECAI国家通常受到全球和区域因素的影响。此外,我们发现,冲击可以造成因素水平的永久变化,但只能造成其增长率的暂时变化。调查结果的主要政策含义是,当局应采取措施促进全要素生产率和REC。这些因素主要是由技术进步驱动的,创新,和效率增益。因此,它们可以同时减少排放,同时促进长期绿色经济增长,这在一定程度上解决了上述复杂性。
    On the one hand, economies, particularly developing ones, need to grow. On the other hand, climate change is the most pressing issue globally, and nations should take the necessary measures. Such a complex task requires new theoretical and empirical models to capture this complexity and provide new insights. Our study uses a newly developed theoretical framework that involves renewable energy consumption (REC) and total factor productivity (TFP) alongside traditional factors of CO2 emissions. It provides policymakers with border information compared to traditional models, such as the Environmental Kuznets Curve (EKC), being limited to income and population. Advanced panel time series methods are also employed, addressing panel data issues while producing not only pooled but also country-specific results. 20 Renewable Energy Country Attractiveness Index (RECAI) nations are considered in this study. The results show that REC, TFP, and exports reduce CO2 emissions with elasticities of 0.3, 0.4, and 0.3, respectively. Oppositely, income and imports increase emissions with elasticities of 0.8 and 0.3. Additionally, we show that RECAI countries are commonly affected by global and regional factors. Moreover, we find that shocks can create permanent changes in the levels of the factors but only temporary changes in their growth rates. The main policy implication of the findings is that authorities should implement measures boosting TFP and REC. These factors are driven mainly by technological progress, innovation, and efficiency gains. Thus, they can simultaneously reduce emissions while promoting long-run green economic growth, which addresses the complexity mentioned above to some extent.

    对城市固体塑料垃圾(MSPW)管理进行全面分析,同时强调全球沿海城市的塑料污染严重程度,以缓解自然界中不断增加的塑料垃圾足迹。因此,决策者对MSPW流量控制的众多管理解决方案的说服可以通过区域一级的冥想系统策略来满足。为了预测专注于系统政策的解决方案,从2023年到2040年,已经开发并模拟了基于代理的系统动力学(ASD)模型,同时考虑了孟加拉国库尔纳市MSPW管理的重要针织参数。基线模拟结果表明,到2040年,人均塑料废物产生量将从2023年的8.92公斤增加到11.6公斤。最终,18年内,塑料垃圾的填埋量已累计达7万吨。此外,河流排放量从2023年的512吨增加到2040年的834吨。因此,到2040年,塑料废物足迹指数(PWFI)值将上升到24。此外,缺乏技术举措导致不可回收塑料废物的对数上升至1.35*1000=1350吨。最后,具有基线因素的两个连续政策情景,例如河流流量控制,增加塑料垃圾的收集和分离,扩大回收业务,并模拟了当地可实现的塑料转化技术。因此,策略2,转化率为69%,80%的源分离,MSPW减少50%的河流排放,从可持续发展的角度来看,从2023年到2040年,最低的PWFI范围为3.97至1.07,人均MSPW产生为7.63至10千克。
    A comprehensive analysis of municipal solid plastic waste (MSPW) management while emphasizing plastic pollution severity in coastal cities around the world is mandatory to alleviate the augmenting plastic waste footprint in nature. Thus, decision-makers\' persuasion for numerous management solutions of MSPW flow-control can be met through meditative systematic strategies at the regional level. To forecast solutions focused on systematic policies, an agent-based system dynamics (ASD) model has been developed and simulated from 2023 to 2040 while considering significant knit parameters for MSPW management of Khulna City in Bangladesh. Baseline simulation results show that per-capita plastic waste generation will increase to 11.6 kg by 2040 from 8.92 kg in 2023. Eventually, the landfilled quantity of plastic waste has accumulated to 70,000 tons within 18 years. Moreover, the riverine discharge has increased to 834 tons in 2040 from a baseline quantity of 512 tons in 2023. So the plastic waste footprint index (PWFI) value rises to 24 by 2040. Furthermore, the absence of technological initiatives is responsible for the logarithmic rise of non-recyclable plastic waste to 1.35*1000=1350 tons. Finally, two consecutive policy scenarios with baseline factors such as controlled riverine discharge, increased collection and separation of plastic waste, expansion of recycle business, and locally achievable plastic conversion technologies have been simulated. Therefore, policy 2, with 69% conversion, 80% source separation, and 50% riverine discharge reduction of MSPW, has been found adequate from a sustainability perspective with the lowest PWFI ranges of 3.97 to 1.07 alongside a per-capita MSPW generation of 7.63 to 10 kg from 2023 till 2040.

    在绿色经济转型持续推进的背景下,积极追求碳减排和尽早实现碳中和目标已成为促进高质量经济发展的重要组成部分。不仅有助于构建人类命运共同体,但这对实现人类文明的可持续发展也至关重要。一个动态演化博弈模型,其中包括政府之间的互动,企业,和公众,构建了在节能减排补贴背景下,三方行为对绿色经济发展的内在影响机制。结果表明,激励和惩罚机制是协调系统成员利益的有效工具。在机制内,公众对奖励表现出更高的敏感性,而企业对罚款表现出更大的反应。因此,政府可以通过激励公众充当第三方调查和监督机构来影响企业的行为。同时,政府可以采取激励和惩罚相结合的机制,鼓励企业加快绿色技术创新。
    In the context of the continued advancement of the green economy transition, the proactive pursuit of carbon emissions reduction and the early attainment of carbon neutrality goals have emerged as essential components in promoting high-quality economic development. Not only does it contribute to the creation of a community of human destiny, but it is also vital to the realization of sustainable development for human civilization. A dynamic evolutionary game model, which encompasses the interactions among government, enterprises, and the public, was constructed to examine the inherent impact mechanisms of the behavior of three players on the development of a green economy under the context of energy saving and emission reduction subsidies. The results showed that the incentive and punishment mechanisms served as effective tools for harmonizing the interests of system members. Within the mechanisms, the public demonstrated a higher sensitivity to rewards, while enterprises exhibited greater responsiveness to fines. Consequently, the government could influence the behavior of enterprises by incentivizing the public to serve as a third-party inquiry and oversight body. Simultaneously, the government could encourage enterprises to expedite green technology innovation by employing a combination of incentive and punishment mechanisms.

    预期寿命可以反映气候政策的健康益处和实施成本。然而,文献中很少有研究量化预期寿命与气候政策之间的关系。在本文中,我们试图通过研究预期寿命与中国全国排放交易计划(CNETS)的关系来缩小研究差距。为了实现这一研究目标,采用可计算一般均衡(CGE)模型来模拟经济系统的运行和减排的政策冲击。CGE模型结果表明,预期寿命因GDP而延长,但因排放而缩短,GDP对预期寿命的影响大于排放影响。气候政策对预期寿命有双重影响,因为它既减轻了排放的负面影响,也减轻了GDP对寿命的积极影响;它对预期寿命的净影响是积极的。预期寿命对GDP有积极影响,这种影响受到气候政策的缓和;具体地说,气候政策加强了预期寿命对GDP的积极影响。在气候政策实施期间,预期寿命对碳排放的影响最小;换句话说,它对减排的影响最小。这些发现意味着气候政策和预期寿命是相辅相成的;政府可以实施气候政策来延长寿命或延长预期寿命,以促进政策实施。
    Life expectancy can reflect both health benefit and implementation cost of climate policy. Nevertheless, little research has quantified the relation between life expectancy and climate policy in literature. In this paper, we attempt to narrow the research gap by studying how life expectancy is related to the Chinese nationwide emission trading scheme (CNETS). To achieve this research target, a Computable General Equilibrium (CGE) model is employed to simulate the operation of the economic system and the policy shock from emission abatement. The CGE model results show that life expectancy is prolonged by GDP but shortened by emissions, and the GDP impact on life expectancy is larger than the emission impact. Climate policy has dual effects on life expectancy because it relieves both negative emission impacts and positive GDP impacts on lifespan; its net effect on life expectancy is positive. Life expectancy positively impacts GDP, and this impact is moderated by climate policy; specifically, climate policy reinforces the positive impact of life expectancy on GDP. Life expectancy minimally affects carbon emissions during climate policy implementation; in other words, it has minimal impacts on emission abatement. These findings imply that climate policy and life expectancy complement each other; the government could implement climate policy to increase lifespan or prolong life expectancy to facilitate policy implementation.

    Traditional industries and industrialization have led to widespread environmental pollution and ecosystem degradation in major river basins globally. Strategies centered on ecological restoration and ecological economy are emerging as essential tools for effective environmental governance. This study aims to investigate how a multifaceted framework for land ecological consolidation, with various developmental goals, can effectively support ecological restoration and sustainability. Through quantitative analysis and in-depth interviews, we investigated the case of Yangtze riverside chemical industrial park in Changzhou. This park pursues ecological and economic sustainability through chemical industry transformation, ecological restoration and protection, ecological management, and ecological industry development. The results show that this practice established a multi-objective action framework rooted in urban renewal, land consolidation, ecological restoration, industrial transformation, and rural revitalization. Through multiplanning integration, integrated implementation and full-cycle profit distribution, the aim of ecological protection has been initially achieved, offering a crucial guarantee for sustainable development. A total of 96.47 ha ecological space expanded, which can generate ecological product worth CNY 7.283 billion, alongside a net economic benefit of CNY 978 million over three decades. The top-down ecological responsibilities, coupled with local developmental demands, have stimulated collaborations within a bottom-up endogenous network comprising government, enterprises, and residents.

    作为湖泊的主要供应来源,入湖河流的水质直接决定着湖泊的水安全和可持续发展。人类活动是河流入湖水质变化的直接原因,土地利用强度是人类活动在地表的直接表现。尽管在研究湖泊土地利用变化与水质之间的关系方面取得了重大进展,还缺乏探索多尺度土地利用强度与水质关系的研究,特别是在不同污染源地区的比较研究中。为了解决这个问题,本研究以滇中3个湖泊为例,采用Pearson相关分析和土地利用强度指数法,探讨不同时空尺度和不同污染源区河流水质与土地利用强度的响应关系。结果表明,土地利用强度与水质总体呈正相关,但在不同尺度和不同污染源区,土地利用强度与不同水质指标的响应关系存在显著差异。与非城市地区相比,土地利用强度对城市水质的影响更为显著。与雨季相比,cDNA之间的相关性,TP,在旱季,NH3-N值和土地利用强度更强,而COD之间的相关性,TN,旱季土地利用强度较弱。当在不同的尺度上观看时,不同的水质指标具有不同的尺度效应,但总的来说,规模越大,相关性越强。因此,在湖泊水环境治理工作中,有必要从多个尺度和角度综合考虑,采取更适合区域水污染防治的措施。
    As the main supply source of lakes, the water quality of the rivers entering the lakes directly determines the water safety and sustainable development of the lakes. Human activities are the direct cause of changes in the water quality of rivers entering lakes, and land use intensity is the direct manifestation of human activities on the land surface. Although significant progress has been made in studying the relationship between land use changes and water quality in lakes, there is still a lack of research on exploring the relationship between land use intensity and water quality at multiple scales, especially in comparative studies of different pollution source areas. To address this problem, this study used Pearson\'s correlation analysis and land use intensity index method to explore the response relationship between river water quality and land use intensity at different spatial and temporal scales and different pollution source areas using three lakes in central Yunnan as examples. The results showed that land use intensity was generally positively correlated with water quality, but the response relationship between land use intensity and different water quality indicators was significantly different at different scales and for different pollution source areas. Compared to non-urban areas, the impact of land use intensity on water quality is more significant in urban areas. Compared to the rainy season, the correlation between CODNa, TP, and NH3-N values and land use intensity is stronger during the dry season, while the correlation between COD, TN, and land use intensity is weaker during the dry season. When viewed at different scales, different water quality indicators have different scale effects, but overall, the larger the scale, the stronger the correlation. Therefore, in the work of lake water environmental governance, it is necessary to consider comprehensively from multiple scales and perspectives and adopt measures that are more suitable for regional water pollution prevention and control.

    中国实施了一系列旨在促进企业绿色创新发展的环保政策,减轻环境污染的不利影响。然而,环境政策的频繁修订和出台也增加了企业对环境不确定性的认知。这项研究,基于上层理论,利用2011-2021年中国上市公司的数据,通过文本分析构建企业感知环境不确定性指数,并实证检验其对绿色创新的影响及其潜在机制和边界效应。结果表明,首先,企业感知的环境不确定性对绿色创新有显著的抑制作用。第二,机理分析发现,企业感知环境不确定性对绿色创新的抑制作用主要表现在两个方面:降低企业信息的透明度和减少研发投入。第三,调节效应发现,政府补贴可以减轻感知环境不确定性对企业绿色创新的抑制影响。换句话说,较高的政府补贴对应的感知环境不确定性对企业绿色创新的抑制作用降低。此外,异质性分析表明,这种抑制作用在非国有企业中更为明显,小企业,和非重污染行业的企业。这项研究对企业在感知到的环境不确定性中利用绿色创新的机会具有巨大的现实意义。促进逐步绿色发展,最终促进企业经济效益和环境效益的协调增长。
    China has implemented a series of environmental policies aimed at promoting green and innovative development by enterprises, to mitigate the adverse effects of environmental pollution. However, the frequent revision and introduction of environmental policies have also increased enterprises\' perception of environmental uncertainty. This study, based on the upper echelon theory, uses data from listed companies in China from 2011 to 2021 to construct an index of perceived environmental uncertainty of firms through textual analysis and empirically examines its impact on green innovation and its potential mechanisms and boundary effects. The results show that, first, perceived environmental uncertainty of firms has a noteworthy inhibiting impact on green innovation. Second, mechanism analysis reveals that perceived environmental uncertainty of firms inhibits green innovation mainly in two ways: reducing the level of transparency in corporate information and reducing R&D investment. Third, the moderating effect finds that government subsidies can mitigate the inhibitory impact of perceived environmental uncertainty on green innovation among firms. In other words, higher government subsidies correspond to a reduced inhibitory effect of perceived environmental uncertainty on green innovation among firms. In addition, heterogeneity analysis shows that this inhibition is more obvious in non-state-owned enterprises, small enterprises, and enterprises in non-heavy pollution industries. This study holds immense practical significance for enterprises in harnessing the opportunities of green innovation amidst perceived environmental uncertainty, facilitating progressive green development, and ultimately fostering the harmonized growth of economic and environmental benefits for enterprises.
