能源政策取决于正确使用方法来指导全球变暖和气候变化等重大能源问题。环境数据分析就是经常用于制定环境政策的方法之一，环境政策与各种能源问题密切相关。不幸的是，将DEA应用于环境政策是不够的，经常误导政策制定者和其他涉及能源问题的个人。本研究为在编制环境评估时使用DEA提供了三条准则。首先，重要的是编写原始公式和双重公式，以确认在DEA评估中是否充分利用了有关所有生产要素（即投入、理想产出和不理想产出）的信息。其次，DEA在径向和非径向测量中具有模型变化。为了避免实证研究中存在的方法论偏差，我们有必要通过不同的模型来研究环境问题。最后，环境影响评估需要纳入自然和管理处置性的概念。自然可弃性表明企业负向适应对不期望产出的监管变化。相反，管理层的可处置性表明企业积极适应监管变化，因为企业认为监管变化是一个新的商业机会。
Energy policy depends on a proper use of methodology in guiding a large energy issue such as the global warming and climate change. DEA is one of such methodologies that are often used for preparing environmental policy, which is closely linked to various energy issues. Unfortunately, the use of DEA applied to environmental policy is insufficient, often misguiding policy makers and other individuals who are involved in energy issues. This study provides three guidelines for a use of DEA in preparing environmental assessment. First, it is important to prepare both primal and dual formulations to confirm whether information regarding all production factors (i.e., inputs, desirable and undesirable outputs) is fully utilized in DEA assessment. Second, DEA has model variations in radial and non-radial measurements. It is necessary for us to examine environmental issues by different models in order to avoid a methodological bias existing in those empirical studies. Finally, DEA environmental assessment needs to incorporate the concept of natural and managerial disposability. The natural disposability indicates that a firm negatively adapts a regulation change on undesirable outputs. In contrast, the managerial disposability indicates that a firm positively adapts the regulation change because the firm considers the regulation change as a new business opportunity.
