    Abstract: The excessive growth of water hyacinth is a common environmental problem in tropical regions. The use of water hyacinth to remove nutrients from bodies of water and to produce biogas is a technically feasible way of controlling water hyacinth, but its environmental and economic performance are not well understood. This study collected data from an experimental biogas plant to develop a lifecycle analysis and a cost benefit analysis for the control of water hyacinth in Dianchi Lake, a eutrophic lake in China. A comparison was made between the proposed project and the current approach at Dianchi Lake of disposing of water hyacinth via collection and landfill. The results revealed that the proposed project is economically feasible with a desirable energy gain. The results also showed that the project is not financially feasible but, compared to the current landfill practice, the government would be able to spend less on controlling water hyacinth if they implemented the proposed project. The removal of water hyacinth to produce biogas can also contribute to water quality improvement and GHG emission reduction; however, these values depend on the scale of processing undertaken by the biogas plant. Since both the current approach and the proposed project can remove nutrients from bodies of water, the additional value resulting from the proposed project of an improvement in water quality only becomes possible when the processing scale of the biogas plant is greater than the amount of water hyacinth disposed of by landfill. The proposed project can avoid methane emissions when the processing scale is greater than the amount of water hyacinth currently disposed of via landfill. The internalization of GHG emission reduction alone is not sufficient to make the project financially feasible and therefore other sources of compensation are needed in order to promote the production of biogas from water hyacinth. The proposed project could be a potential microeconomic option, which could respond to China’s macro water pollution control policies, renewable energy development, and energy saving and emissions reduction. However, institutional arrangements are required to coordinate these diverse policies when they are applied to the proposed project.

  2. By: Wenli Cheng; Dingsheng Zhang; CEMA, Central University of Finance and Economics
    Abstract: This paper presents three simple models to study how prices, politics and persuasion may each play a role in environmental policymaking. Our conclusions are twofold. First, in the absence of increasing returns, requiring the polluting industry to purchase pollution permits can internalize the negative externality of pollution, and the optimal price of pollution permits should increase with the disutility of pollution. Second, with increasing returns in the industry using clean technologies, it is welfare enhancing to complement the pollution permits policy with a tax-funded subsidy to the clean industry, or with a tax-funded public campaign to persuade consumers to move away from the pollution generating goods.
    Keywords: pollution permits, increasing returns; advertising

  3. By: Smita Shingrup
    Abstract: Environmental sustainability is not simply a matter of compliance or risk management. People are concerned about the environment and marketers have to begun to modify their practices in an attempt to attract consumer’s new concern. Marketers are increasingly recognizing that the many competitive advantages and business opportunities to be gained from Eco Sustainability and Green Marketing. Key words: Ecolabels, Green Marketing
