Balancing environmental and industry sustainability: A case study of the US gold mining industry 总被引:2,自引:0,他引:2
Bruce Finnie Jeffrey Stuart Linda Gibson Fern Zabriskie 《Journal of environmental management》2009,90(12):3690-3699
Mandatory insurance requirements and/or mitigation fees (royalties) for mining companies may help reduce environmental risk exposure for the federal government. Mining is examined since the Environmental Protection Agency (EPA) Toxic Release Inventory reveals that this sector produces more hazardous waste than any other industrial sector. Although uncommon, environmental expense can exceed hundreds of millions of dollars per development. Of particular concern is the potential for mines to become unfunded Superfund sites. Monte Carlo simulation of risk exposure is used to establish a plausible range of unfunded federal liabilities associated with cyanide-leach gold mining. A model is developed to assess these costs and their impact on both the federal budget and corporate profitability (i.e., industry sustainability), particularly if such costs are borne by offending firms. 相似文献

In the latter half of the 20th century, native pine woodlands in Scotland were restricted to small remnant areas within which there was little regeneration. These woodlands are important from a conservation perspective and are habitat for numerous species of conservation concern. Recent developments have seen a large increase in interest in woodland restoration and a dramatic increase in regeneration and woodland spread. The proximate factor enabling this regeneration is a reduction in grazing pressure from sheep and, particularly, deer. However, this has only been possible as a result of a complex interplay between ecological, political and socio-economic factors. We are currently seeing the decline of land management practices instituted 150-200 years ago, changes in land ownership patterns, cultural revival, and changes in societal perceptions of the Scottish landscape. These all feed into the current move to return large areas of the Scottish Highlands to tree cover. I emphasize the need to consider restoration in a multidisciplinary framework which accounts not just for the ecology involved but also the historical and cultural context. 相似文献

The actions performed by individuals, as consumers and citizens, have aggregate negative consequences for the environment.
The question asked in this paper is to what extent it is reasonable to hold individuals and institutions responsible for environmental
problems. A distinction is made between backward-looking and forward-looking responsibility. Previously, individuals were
not seen as being responsible for environmental problems, but an idea that is now sometimes implicitly or explicitly embraced
in the public debate on environmental problems is that individuals are appropriate targets for blame when they perform actions
that are harmful to the environment. This idea is criticized in this paper. It is argued that instead of blaming individuals
for performing actions that are not environmentally friendly we should ascribe forward-looking responsibility to individuals,
a notion that focuses more on capacity and resources than causation and blameworthiness. Furthermore, it is important to emphasize
that a great share of forward-looking responsibility should also be ascribed to institutional agents, primarily governments
and corporations. The urge to ascribe forward-looking responsibility to institutional agents is motivated by the efficiency
aim of responsibility distributions. Simply put, if responsibility is ascribed to governments and corporations there is a
better chance of creating a society in which the opportunities to act in an environmentally friendly way increase. 相似文献

The paper provides an overview of EIA system applications and assesses its effectiveness in Lithuania. A combination of archival research and quantitative/qualitative analysis was used to identify the main shortcomings of the EIA process in Lithuania: subjectivity in forecasting environmental effects, insufficient consideration of alternatives, politicisation of the process and incompetence of authorities involved. The research revealed that a thorough knowledge of EIA procedures and legal requirements may be a solution to these problems, especially when the stages related to forecasting the effects and evaluating the results are strictly reserved for recognized experts. The work concludes on the suggestions to involve in EIA process relevant authorities and to increase the competence of EIA practitioners. 相似文献
