We estimate the impacts of the Climate Change Levy (CCL) on manufacturing plants using panel data from the UK production census. Our identification strategy builds on the comparison of outcomes between plants subject to the CCL and plants that were granted an 80% discount on the levy after joining a Climate Change Agreement (CCA). Exploiting exogenous variation in eligibility for CCA participation, we find that the CCL had a strong negative impact on energy intensity and electricity use. We cannot reject the hypothesis that the tax had no detrimental effects on economic performance and on plant exit.

We use an innovative methodology to measure management practices in over 300 manufacturing firms in the UK. We then match this management data to production and energy usage information for establishments owned by these firms. We find that establishments in better managed firms are significantly less energy intensive. They use less energy per unit of output, and also in relation to other factor inputs. This is quantitatively substantial: going from the 25th to the 75th percentile of management practices is associated with a 17.4% reduction in energy intensity. This negative relationship is robust to a variety of controls for industry, location, technology and other factor inputs. Better managed firms are also significantly more productive. One interpretation of these results is that well m...
