Climate change and various pollutants have been influencing our societies and economies. Recently, many individuals, firms and public entities (e.g., the United Nations) are interested in environmental protection (e.g., reduction of CO2 emission). This study discusses a use of DEA (Data...

This study compares among fossil fuel power plants in PJM and California ISO by their unified (operational and environmental) performance. DEA (Data Envelopment Analysis) is used as a methodology. For comparative analysis, DEA incorporates strategic concepts such as natural and managerial...

This study discusses a new use of window analysis for DEA environmental assessment in a time horizon where DEA stands for Data Envelopment Analysis. The data sets on environmental protection are often structured by time series. In applying DEA to environmental assessment, it is necessary for us...

This study proposes a use of Data Envelopment Analysis (DEA) to measure Returns to Scale (RTS) of US coal-fired power plants. The power plants produce not only desirable outputs (e.g., electricity) but also undesirable outputs (e.g., CO2 and NOx) as a result of their plant operations. Therefore,...

Environmental assessment recently becomes a major policy issue in the world. This study discusses how to apply Data Envelopment Analysis (DEA) for environmental assessment. An important feature of the DEA environmental assessment is that it needs to classify outputs into desirable (good) and...

Environmental assessment recently becomes a major policy issue all over the world. This study discusses how to use Data Environment Analysis (DEA) for environmental assessment for planning corporate strategy and international competitiveness. An important feature of DEA environmental assessment...

This study proposes a use of Data Envelopment Analysis (DEA) for environmental assessment. All radial and non-radial models are discussed under natural and managerial disposability. The natural disposability implies corporate strategy by which a firm attempts to decrease an input vector to...

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...
