This paper proposes a non-radial Malmquist CO2 emission performance index (NMCPI) for measuring dynamic changes in … total-factor CO2 emission performance over time. This index enables the consideration of non-radial slacks in the … conventional Malmquist CO2 emission index (MCPI). The NMCPI is calculated based on a non-radial directional distance function …
