This chapter investigates the patterns of emission efficiency growth of 23 manufacturing sectors in 12 European countries with a focus on five emissions (CO2, NOx, NMVOC, SOx and CO). Emission efficiency growth is expected to be triggered by an improvement in the efficiency of frontier countries through the diffusion of better technologies to laggard countries. This effect is likely to differ according to the distance from the frontier country. Finally, the role of productivity patterns (total factor productivity) and energy price dynamics is assessed. Results based on the European NAMEA (National Accounting Matrix including Environmental Accounts) further merged with sector accounts highlight significant spillovers from leaders in emission efficiency and a general tendency to converge for laggard countries and sectors (except for NMVOC emission efficiency). Energy prices induce substantial improvements in emission efficiency, with the effect being generally stronger for sectors and countries farther away from the emission efficiency frontier. Finally, total factor productivity (TFP) is strongly correlated with emission efficiency, while the distance from TFP frontier significantly harms emission efficiency growth.
