Does Increased Extraction of Natural Gas Reduce Carbon Emissions?

Without an international climate agreement, extraction of more natural gas could reduce emissions of CO₂ as more clean natural gas may drive out dirty coal and oil. Using a computable equilibrium model for the Western European electricity and natural gas markets, we examine whether increased extraction of natural gas in Norway reduces global emissions of CO₂. We find that both in the short run and in the long run total emissions are reduced if the additional quantity of natural gas is used in gas power production in Norway. If instead the additional quantity is exported directly, total emissions increase both in the short run and in the long run. However, if modest CO₂-taxes are imposed, increased extraction of natural gas will reduce CO₂ emissions also when the additional natural gas is exported directed.earlier version of this paper was presented at the 25th Annual IAEE International Conference in Aberdeen June 2002.     

Rethinking the costs related to global warming: A survey of the issues

One approach to the economic analysis of global warming seeks to balance the costs of damage from or adaptation to it with the costs of mitigating it. The costs of adaptation and damage have been estimated using techniques of environmental evaluation, but are subject to a wide margin of uncertainty. The costs of mitigation, principally by reducing the emissions of CO₂, have been estimated using different kinds of economic models, some of the results of which have suggested that very little abatement of carbon emissions is justified before the costs of abatement exceed the benefits of it in terms of foregone damage and adaptation costs. The paper analyses the extent to which this conclusion is a function of the modelling assumptions and techniques used, rather than likely practical outcomes, with regard to the models' treatment of unemployed resources, revenue recycling, prior distortions in the economy due to the tax system and possible dynamic effects from the introduction of a carbon-energy tax. It concludes that, with different and arguably more appropriate treatment of the above issues, especially when the secondary benefits of reducing CO₂ emissions are also taken into account, it is not clear that even substantial reductions in the use of fossil fuels will incur net costs, especially if there is the prospect of even moderate costs from global warming.

油气勘探投资项目评价指标的探讨

油气田勘探开发项目其技术经济特点不同于一般工业性项目，因其原油产量逐年递减，而收人也相对逐年减少，造成了项目单位成本逐年升高，利润指标逐年降低，文章就从油气田开发项目的一般生产规律和技术经济特点出发。初步研究了该类项目评价体系和基准值等相关问题，提出了初步的意见和建议，对决策工作能起到一定的作用。     

天然气甲烷值的计算方法及其标准化

天然气用作发动机燃料时，其抗爆性是一项重要指标。目前国外表示天然气抗爆性的方法甚多，但广泛应用的只有两个方法，即甲烷值(MN)法和辛烷值(MON)法。两者均以天然气的组成为计算依据，故相互间可建立换算的关联式。根据国内外的研究现状，提出了天然气甲烷值计算方法标准化的建议。
