企业内部碳交易市场探析

随着气候变化问题的加剧,企业逐渐认识到将气候变化问题上升到企业战略高度的重要性.在企业的生产运营过程中有效减少温室气体排放量,关系到企业的可持续发展.但目前企业自主减排的动力不足,这不仅需要外部激励,更需要企业具有内生性动力.而只有依靠企业运行机制的修整和改良才能在根本上激励企业减排的自发性.企业内部碳交易市场的构建就能起到这个作用——它将市场机制引入企业,基于“总量管制和排放交易”理念,建立企业内部碳交易市场,在企业内部各部门之间进行温室气体排放权的重新分配和交易.它具体包括三个互为联系的子市场,即碳信用市场、碳项目市场和现碳交易市场,各子市场的良好运作也需要三重保障,即减排基金的合理构建、产权的明晰和监督机制的完善.通过构建内部碳交易市场,实现温室气体排放权在企业内部的市场化运作,提高温室气体排放权的利用效率,从而减少企业的温室气体排放量,降低企业的生产运营成本,保障企业抓住气候变化带来的战略机遇,规避风险,实现可持续发展.     

海河流域水污染成因与多层次治理结构的制度选择

海河流域是我国经济相对发达地区,但也是水环境污染十分严重地区,水污染的有效治理对区域内资源节约型和环境友好型社会建设具有重要意义。本文在分析海河流域水污染现状及成因的基础上,指出单纯依赖以排污权交易为主的市场化手段进行治污的局限性。最终,分别提出针对省(市)级政府、地市级政府和企业三个层面应该采取的多层次水污染治理结构的制度选择。     

市场失灵、非市场价值与农地非农化过度性损失

农地资源不仅具有经济生产功能,还具有大气调节、涵养水源、保持土壤成分、休闲娱乐等多种生态功能,而在非农化过程中这些功能在市场中没有以价格的形式体现出来,没有包含在农地的现实价值中。因而,有必要对农地的非市场功能进行详尽的分类及价值估算。同时,将由于市场失灵而没能包含到农地总价值中的生态环境等非市场价值纳入到成本效益决策中,来减少市场失灵所造成的农地非农化的效率损失。通过对农地非市场功能的具体分类及量化,测算我国不同经济区域因市场失灵导致的农地非农化过度损失,结果显示,代表东、中、西部地区的江苏、湖北和甘肃省的农地非农化过度损失Ⅰ分别为31.58%、38.13%和43.85%,这为我国农地非农化的行为调控及相应公共政策措施的制订和实施提供了理论依据。     

The Dual Model for Tourism Resource Productivity Improvement

For natural resource science, resource productivity studying is an important subject. But researches on tourism resource productivity are limited. The most significant influencing factor on tourism resource productivity is the potential market scale of tourist locations, and second most important influencing factor is the resource endowment. Regional urban population is significantly correlated with region tourist numbers, being the decisive factor of region potential tour market scale. In tourism development, the dual model should be adopted: on one hand to enhance tour spot attractiveness, on the other hand to cultivate the potential market by improving urbanization level and other means. In the situation of tourism development fever spreading, the dual model for improving tourism productivity helps to avoid the "Great Leap Forward" which means that too rapid tourism construction divorces from actual market demand.     

Defending the scientific integrity of conservation‐policy processes

Government agencies faced with politically controversial decisions often discount or ignore scientific information, whether from agency staff or nongovernmental scientists. Recent developments in scientific integrity (the ability to perform, use, communicate, and publish science free from censorship or political interference) in Canada, Australia, and the United States demonstrate a similar trajectory. A perceived increase in scientific‐integrity abuses provokes concerted pressure by the scientific community, leading to efforts to improve scientific‐integrity protections under a new administration. However, protections are often inconsistently applied and are at risk of reversal under administrations publicly hostile to evidence‐based policy. We compared recent challenges to scientific integrity to determine what aspects of scientific input into conservation policy are most at risk of political distortion and what can be done to strengthen safeguards against such abuses. To ensure the integrity of outbound communications from government scientists to the public, we suggest governments strengthen scientific integrity policies, include scientists’ right to speak freely in collective‐bargaining agreements, guarantee public access to scientific information, and strengthen agency culture supporting scientific integrity. To ensure the transparency and integrity with which information from nongovernmental scientists (e.g., submitted comments or formal policy reviews) informs the policy process, we suggest governments broaden the scope of independent reviews, ensure greater diversity of expert input and transparency regarding conflicts of interest, require a substantive response to input from agencies, and engage proactively with scientific societies. For their part, scientists and scientific societies have a responsibility to engage with the public to affirm that science is a crucial resource for developing evidence‐based policy and regulations in the public interest.     

THE FLOOD HAZARD AND DYNAMICS OF THE URBAN RESIDENTIAL LAND MARKET1

ABSTRACT: Literature on the flood hazard/residential land market relationship is full of contradictory findings, many of which are counter-intuitive to the belief that flooding has a negative impact on house prices. This research advances a conceptual framework through which these relationships might be re-examined. Based on the expected utility model, the theoretical framework integrates the economic notion of capitalization with spatial and temporal characteristics of the flood hazard. Four communities with different flood regimes are used to test the effect of flooding on the residential real estate market. Results show that, (1) there is an identifiable relationship between characteristics of the flood hazard and changes in house values; (2) the length of the recovery period is dependent on characteristics and expectations of flooding, attributes of the real estate market, and availability of capital to fuel recovery; and (3) dynamics of the urban market and spatial extent of the flood hazard influence these relationships. Further research is now necessary to examine these findings under different spatial, temporal, hydrological, and socio-economic conditions.     

The case for free market environmentalism

Environmental Ethics is the ethics of how we humans are to relate to each other about the environment we live in. The best way to adjust inevitable differences among us in this respect is by private property. Each person takes the best care of what he owns, and ownership entails the free market, which enables people to make mutually advantageous trades with those who might use it even better. Public regulation, by contrast, becomes management in the interests of the regulators, or of special interests, such as lovers of rare species-not the people they're supposed to be serving.
