BHATTACHARYA Khalisani Mahavidyalaya, Hooghly, W. B., India Kalyani University, Nadia, W. B., India In the evolution of carbon dioxide emission intensity, the role of energy intensity or carbonization index is mainly an empirical issue that cannot be resolved with certainty from the experience of a group of countries during a given period of time. The present empirical study reveals that CO<SUB>2</SUB> emission intensity cannot be evaluated unambiguously using either variation in carbon emission factor or energy intensity as the criterion. Different levels of CO<SUB>2</SUB> emission intensities in different regions result from different causes. These include large variation in explanatory factors in the data, the measure of economic output, and structural comparability. J. W.
