Optimal Timing to Adopt an Environmental Policy in a Strategic Framework

In this paper, the problem of optimal timing, when to adopt an environmental policy in a strategic framework is considered. Using real options theory and some basic tools of game theory, we show that, under certain assumptions, a country behaving strategically should wait longer before adopting such a policy than if it behaves unstrategically or within a larger entity. Such a postponed decision is sub-optimal as regards to the environment protection.     

Can health feasibly be considered as part of the planning process in Scotland?

The planning system is significant because of its capacity to determine the quality of the built environment as well as the health, well-being and quality of life of the individuals and communities therein. Development planning is especially important because of the long-term impact of the decisions. This paper was developed in response to increasing recognition amongst HIA practitioners in Scotland of the importance of planning for health. It focuses on the relationship between the planning system in Scotland, specifically the Development Planning element of it, and population health and considers how the health impact assessment (HIA) approach can facilitate and support joint working with planners. In particular, consideration is given to the potential impact of the introduction of Strategic Environmental Assessment (SEA) on the linkages between health, HIA and planning.

环境伦理·生态文明·环境政策取向

环境伦理是一个伴随人类文明发展历程的社会主题。由于人类缺乏对生态文明、环境伦理、环境道德的合理吸纳,造成愈演愈烈的生态恶果。人类文明正处于历史转折点,必须对传统人类文明加以辩证之否定,融物质文明、精神文明、生态文明于一体,通过提供理性制度安排、调整利益分配格局来规范人类的道德伦理观念。

Climate Change Policy in European Countries and its effects on industry

In this paper we discuss the effects ofdifferent climate change policies onindustrial activity and on welfare. Wecompare the effects of carbon taxes andgrandfathered permits and the effects ofexemptions for energy-intensive industries.We survey first the insights from economictheory and from model experiments for theUS. Next we use a general equilibrium modelto assess the effect of different climatechange policies on industrial activity persector and per member country in the EU. Wepay particular attention to the effects ofpolicies where one EU member state exemptsits energy-intensive sectors from abatementefforts. The main findings are that, in theEU, the effects on industrial activity andthe welfare costs of tradable permits orcarbon taxes are small when no industrialsectors are exempted. When one membercountry exempts its energy intensivesector, this will reduce somewhat theimpact on its activity level but willgenerate an extra welfare cost for theEU.

Geological CO2 Storage as a Climate Change Mitigation Option

Carbon dioxide (CO₂₎ capture and storage is increasingly being considered as an important climate change mitigation option. This paper explores provisions for including geological CO₂ storage in climate policy. The storage capacity of Norway's Continental Shelf is alone sufficient to store a large share of European CO₂ emissions for many decades. If CO₂ is injected into oil reservoirs there is an additional benefit in terms of enhanced oil recovery. However, there are significant technical and economic challenges, including the large investment in infrastructure required, with related economies of scale properties. Thus CO₂ capture, transportation and storage projects are likely to be more economically attractive if developed on a large scale, which could mean involving two or more nations. An additional challenge is the risk of future leakages from storage sites, where the government must take on a major responsibility. In institutional and policy terms, important challenges are the unsettled status of geological CO₂ storage as a policy measure in the Kyoto Protocol, lack of relevant reporting and verification procedures, and lack of decisions on how the option should be linked to the flexibility mechanisms under the Kyoto Protocol. In terms of competitiveness with expected prices for CO₂ permits under Kyoto Protocol trading, the relatively high costs per tonne of CO₂ stored means that geological CO₂ storage is primarily of interest where enhanced oil recovery is possible. These shortcomings and uncertainties mean that companies and governments today only have weak incentives to venture into geological CO₂ storage.
