measuring efficiency levels and productivity changes mainly deal with the economic considerations. Several models have proposed … environmental efficiency and productivity change measures. However, they do not satisfy the first and second laws of thermodynamics … which govern all production processes. This thesis proposes an analytical framework which accommodates the efficiency and …
