Non-metallic mineral resources, albeit very important to meet the needs of the Brazilian population and for exportation, are ill-favored by governments and ignored by the public. Most of this mining is performed by small-scale companies and informal operations that cause extensive and widespread environmental damages. In addition to examining the current state of the industry and its environmental impacts, this paper outlines a series of initiatives for improving (environmental) performance. The suggestions made include improved coordination among public entities responsible for the control of the mining sector; the undertaking of environmental management and reclamation initiatives; research and diffusion of mining and environmental technology; the development and implementation of appropriate licensing procedures for small-scale mines; and the reviewing of environmental impact evaluation and enforcement procedures, and improved regional planning. It is concluded, however, that the proposals will only become a reality if the necessary political actions are taken, and are supported by adequate financing and technical assistance.  相似文献

Mexico ranks among the 11 major producer countries of minerals worldwide; its open pit and underground systems are 500 years old. This paper presents an overview of the Mexican mining industry from technological development, historical and economic perspectives. The efforts made by mining companies to address issues of environmental management and sustainable development expressed in national and international frameworks, as well as the Mexican environmental regulatory framework for the mining sector, are analyzed. Since, among others, life cycle assessment (LCA) has been recognized as a key topic to promote sustainable development in the Latin American and Caribbean region, this paper also examines the application of LCA in mining. Two life cycle approaches are presented: a national life cycle inventory for base metals, and an integral life cycle model for the management of mining processes.  相似文献

This article reports on a stakeholder engagement process to develop the International Guidelines on Mercury Management in Small-Scale Gold Mining. Commissioned by the United Nations Global Mercury Project, the purpose of the guidelines is to assist policymakers, practitioners, researchers, miners and the public in developing strategies for reducing mercury use, eliminating major pollution point sources and reducing risks. The guidelines are proposed with the view of supporting miners and their communities by promoting safer, more efficient practices that improve environmental and human health. The paper discusses challenges in addressing mercury issues and technical measures in the guidelines. The paper also highlights the need for interactive engagement in communities to discuss and adapt the guidelines as appropriate, in order to create technology transfer strategies, regulatory measures and strategic priorities that are suitable to the local context.  相似文献

Although small-scale mining provides a wealth of socioeconomic benefits to the rural inhabitants of developing countries, there is often total disregard for the environment industry-wide. This paper focuses upon some of the key environmental issues in the Indian small-scale mining industry. The geo-environmental factors constraining the mining of the Himalayan limestone, magnetite, phosphate, and polymetallic sulphur ore deposits are discussed, and the environmental impacts of small-scale operations working prospective deposits are detailed. The paper further examines the schematics of the Environmental Management Plan (EMP) adopted for small-scale mines in India. It is concluded, however, that widespread environmental improvement can only be achieved industry-wide if additional mining cooperatives are formed, and the Indian Government, through their Department of Environment, oversees the implementation of effective mitigation practices for small scale-mines, particularly at the university level.  相似文献

中、小型企业缺乏有关企业社会责任活动的参与。尽管单独的中、小型企业对环境的影响不大,但中、小型企业集合起来对环境的影响还是很明显的。企业所有者-管理者的管理方式和道德观念会影响到企业的决策。因此,会对企业的环境行为有直接的影响。虽然,倡导利用环境保护建立企业竞争优势,但许多企业的实施成本是不可能转移给消费者的。本文简要的综述了有关文献后,报告了对这一问题的探索性调查,结果表明无论小企业的管理者怎样表达出对环境问题的关心,都不能转化为较好的废弃物管理。  相似文献

The mining industry plays an important role in the local economy in many islands of the Cyclades, contributing significantly to overall growth. However, it has simultaneously caused many environmental problems and has had adverse impacts upon other important economic activities, such as tourism. As a result, questions have been raised as to whether mining should be allowed to continue. This paper assesses the mining operations of the Cyclades, examining the corporate environmental management of mining companies and the process of granting permission for mining operations. Specifically, the regulatory and environmental problems of mining operations are assessed, and the process of obtaining a ‘social licence to operate’ is explored. A number of recommendations are made in order to overcome regulatory inefficiencies and promote corporate environmental management in the mining sector of the Cyclades.  相似文献

Understanding the material purchase value of wastes and emissions and related processing costs is the essential contribution of an Environmental Management Accounting methodology proposed by a United Nations expert working group organised through the Division for Sustainable Development (UNDSD). Tracing costs and benefits according to this UNDSD methodology, considered as a “reflexive” modernization strategy in this article, sheds new light on cleaner production initiatives for corporate sustainability. Information on the first category of costs, waste and emission treatment, is generally the most accurate. Information on the second category, prevention and environmental management costs, is more difficult to determine because this category overlaps with, or is confused with, the first category of costs. Data for the two novel and innovative cost categories of the material purchase value of waste and emissions and related processing costs are even harder to obtain. Frequently, the costs are either hidden in overhead accounts or are not recorded because they are not required in conventional accounting systems. The outcome is that companies, even though they may profess otherwise, have very little knowledge about their full environmental costs, cost saving opportunities, or how best to achieve cleaner production initiatives to promote corporate sustainability. A more systematic application of the UNDSD EMA methodology would provide a better record of costs and act as a catalyst in promoting cleaner production processes. This application inevitably requires “reflexive institutions” including “reflexive corporations”, that is, corporations with the capacity to examine the side effects of their operations as modernization rebounds upon them.  相似文献

Why should organizations and accountants care about environmental issues? Environmental performance and disclosure pressures from the supply chain, finance providers, regulatory agencies, and other stakeholders result in ever-increasing environment-related costs for organizations, but there is also an increasing recognition of the potential monetary benefits of improved environmental performance. There is also growing consensus that traditional accounting practices do not adequately provide the information required for environmental management and the strategic decisions related to it.Environmental Management Accounting (EMA) has been promoted by the Working Group on EMA of the United Nations Division for Sustainable Development UN DSD EMA WG and the publications commissioned by it [UNDESA/DSD, 2001. United Nations Division for Sustainable Development. Environmental Management Accounting, Procedures and Principles. United Nations Publications, New York/Geneva, http://www.un.org/esa/sustdev/sdissues/technology/estema1.htm; UNDESA/DSD, 2002. United Nations Division for Sustainable Development. Environmental Management Accounting: Policies and Linkages. United Nations Publications, New York/Geneva, http://www.un.org/esa/sustdev/sdissues/technology/estema1.htm]. Recently, IFAC has published a guidance document on EMA [International Federation of Accountants (IFAC), 2005. International Guidance Document of EMA. IFAC, New York, http://www.ifac.org] that will further promote its application among accountants.This special issue of the Journal of Cleaner Production on EMA focuses on this methodological background as well as upon experiences from case studies from Australia, Austria, Argentina, Canada, Japan and Lithuania.  相似文献
