构建我国水污染税制的设想

在市场经济条件下,必须更多地运用税收手段促进水资源保护和水污染治理,开征水污染税很有必要。我国制定水污染税应遵循:“污染者付费”、“专税专用”的原则。     

环境管制目标与管制手段分析

环境管制目标具有双重性。影响该目标实现的因素有信息的完备程度与管制制度的完善及管制机构的健全。我国目前环境管制的主要手段是排污收费制度,这一制度对于环境管制目标偏离程度较大,对效率损害较严重。为此应从改革现行的排污收费制度,加强管制制度、管制机构的建设以及建立信息披露机制入手,来改进我国环境管制工作,以实现可持续发展目标。

刍议建立和完善公众参与陆源污染防治机制

面对日益严重的海洋环境状况,学界、政府、企业与公民必须重新审视政府主导型的海洋管理模式,需要从根本上改变对公众参与海洋保护的态度,为其提供参与的途径和程序,如果没有程序性的法律规定,那么实体权利义务规定就只能是一纸空文。建立和完善公众参与陆源污染防治机制应从以下几方面着手:完善陆源污染防治法律制度,保障公众参与机制畅通,调动企业防治陆源污染的积极性,加强对公众海洋环保意识的教育和管理。     

Time-related changes in cardiac ct images of rabbits died from four kinds of execution

Objective To explore the feasibility and appropriate parameters for estimating postmortem interval (PMI) through time-related CT imaging into dynamically monitoring the cardiac changes of rabbits died from four kinds of execution. Methods The experimental rabbits were executed with four disposals of air embolism, strangulation, drowning and hemorrhagic shock. The dead rabbits were observed of their hearts with CT scanning every 6 hours within 120h from the death moment, having the obtained time-different CT images and mean CT values examined. With the cardiac average CT values of rabbits died from discrepant execution, four relevant regression equations were established against the elapsing time (i.e. PMI). Results The CT images of post-death cardiac tissue of rabbits died from one of four executions did change regularly with the PMI elongating, showing consistent with the autopsy verification. The binomial regressive equations were established between the post-death cardiac average CT value and PMI from four executions, demonstrating statistically significant (P<0.05). Conclusion The postmortem cardiac CT imaging into PMI analysis, plus the relating regression equation, provides a new objective visual quantitative approach and reference for forensic medicine to infer the time of death. © 2021, Editorial Office of Forensic Science and Technology.

Rethinking the Porter Hypothesis: The Underappreciated Importance of Value Appropriation and Pollution Intensity

The impact of environmental regulation on the competitiveness of firms and industries remains a hot topic. Since the formulation of the Porter hypothesis, scholars from different research areas have tried to confirm or deny it. However, despite a vast literature engaging this debate, it remains unclear whether and under what conditions the hypothesis could be considered valid. We believe that this is due to the need to consider some additional factors. The aim of this review is to propose additional and significant themes, namely value appropriation and pollution intensity, to be considered when examining the impact of environmental regulation on the innovation and profitability of firms. Results show that the validity of the Porter hypothesis cannot be proved in any condition, but at the same time, there are additional factors that have a relevant influence on that construct, which can lead to a validation or rejection of the hypothesis.     

The Science–Policy Nexus in Collaborative Governance: Use of Science in Ecosystem Recovery Planning

Across many social–ecological systems, policy makers and scholars increasingly call for science to inform policy. The science–policy interface becomes especially complex as collaborative approaches include multiple stakeholders working together across jurisdictions. Unfortunately little is known about how much and how science is used in collaborative governance for social–ecological systems. This exploratory study examines instrumental, conceptual, and symbolic use of science in a science‐rich collaborative planning case in the Puget Sound, USA. It also examines the influence of science, relative to other factors, in collaborative planning, and what factors affect it. Results from a survey and document analysis indicate the prevalence of conceptual use of science, with relatively little symbolic use. Some factors promoting conceptual and instrumental use discourage symbolic use. Overall, while science is seen as influential in this science‐rich context, its influence is balanced by local stakeholder preferences and contextual information.     

Historical review of Taiwan＇s environmental legislative adjustment and its implications under international agreements

After 1960s, the economic developmental explosion in Taiwan had brought serious environmental degradations including the air and water pollution, waste disposal, as well as wildlife problems. Since then, Taiwanese has begun environmental protection movements striving for ＂environmental rights＂. In addition, international environmental agreements have grown with great speed in the past decades. Although Taiwan never signed or joined any international environmental agreements or organizations, the development of international environmental laws still deeply affect Taiwan environmental regulations. Under this global trend, Taiwan has to cooperate with international community and to obey international environmental agreements. Thus Taiwan had passed numerous environmental laws including ＂Air Pollution Control Act,＂ ＂Water Pollution Control Act,＂ ＂Noise Control Act,＂ ＂Waste Management Act,＂ ＂Toxic Chemicals Management Act,＂ ＂Wildlife Protection Act,＂ and ＂Nuisance Dispute Resolution Act.＂ Thus the article will examine Taiwan＇s environmental administration, regulations as well as the implication under international agreements.     

Best Available Techniques (BAT) and Coal-fired Power Stations: Can the Energy Gap be Plugged Without Increasing Emissions?

At present, there is much anxiety regarding the security ofenergy supplies; for example, the UK and other European Statesare set to become increasingly dependant upon imports of naturalgas from states with which political relations are often strained.These uncertainties are felt acutely by the electricity generatingsector, which is facing major challenges regarding the choiceof fuel mix in the years ahead. Nuclear energy may provide analternative; however, in the UK, progress in replacing the firstgeneration reactors is exceedingly slow. A number of operatorsare looking to coal as a means of plugging the energy gap. However,in the light of ever more stringent legal controls on emissions,this step cannot be taken without the adoption of sophisticatedpollution abatement technology. This article examines the rolewhich legal concepts such as Best Available Techniques (BAT)must play in bringing about these changes.     

The Role of French Environmental Associations in Civil Liability for Environmental Harm: Courtesy of Erika

Last January, the Tribunal Correctionnel de Paris, in its decisionconcerning the Erika oil spill, clearly recognised the rightof environmental associations to claim compensation for damagedone to the environment per se. Taking the judgment as a startingpoint, this article gives a brief insight into the French regimeof civil liability for environmental harm, with a special focuson the role, as provided in the regime and further developedin the case-law, of French environmental associations. The latterare formally recognised, under certain conditions, as "guardians"of the collective interest to environmental protection. As aresult, they are entitled to bring civil party petitions beforecriminal courts in case of -largely defined- "environmentalcrimes". These procedural rights have been broadly interpretedby (criminal, as well as civil) courts and effectively usedby associations to ensure that the "polluter pays" and thatcivil damages reflect, to the extent possible, the reality ofenvironmental harm, while serving the interests of general prevention.
