The impact of disposability characteristics on carbon efficiency from a potential emissions reduction perspective

Carbon emission efficiency is the key to measuring the overall level of carbon emissions. Carbon emissions in actual production activities are uncertain, and the measurement results are biased from the perspective of direct carbon emissions. Based on the perspective of implied emission reduction potential, this study differentiates the carbon emission efficiency and emission reduction potential of different disposability, under the semi -disposability hypothesis, the interval number E-DEA model of the undesirable output is proposed. Then a new production possibility set is constructed to solve the overlapping problem of interval planning. Finally, the proposed method is applied to measure the emission reduction potential of 30 provinces in China. The results indicate that the weak disposability hypothesis always underestimates the emission reduction potential. The strong disposability hypothesis always overestimates the emission reduction potential. While the semi -disposability hypothesis can evaluate the emission reduction potential more scientifically and reasonably, tak-ing into account the influence of different technical characteristics or the managerial capacity of decision -makers.
