A new energy decomposition method, called the Log-Mean Divisia Index Method I (LMDI I), is presented. It has the desirable properties of perfect decomposition and consistency in aggregation. Perfect decomposition ensures that the decomposition results obtained do not contain a residual term....

This paper introduces a new method to estimate and decompose sources of carbon dioxide emissions using the input–output model. This method uses what we call the ‘mean rate-of-change index’ for weights of the decomposed terms. In this journal, Ang et al. asserted that logarithmic mean...

This paper presents a non-radial directional distance function approach to modeling energy and CO2emission performance in electricity generation from the production efficiency point of view. We first define and construct the environmental production technologies for the countries with and...

Many differences can be found among the existing accounting systems for tracking economy-wide energy efficiency trends. There is a need for greater uniformity in the design and application of such systems but a formal study does not exist. This paper seeks to fill some of the gaps. It begins by...

Energy-related CO2 emissions embodied in international trade have been widely studied by researchers using the environmental input-output analysis framework. It is well known that both sector aggregation and spatial aggregation affect the results obtained in such studies. With regard to the...

We present five performance indicators for electricity generation for 129 countries using the 2005 data. These indicators, measured at the national level, are the aggregate CO2 intensity of electricity production, the efficiencies of coal, oil and gas generation and the share of electricity...
