This paper examines convergence clubs for per capita CO2 emissions among 28 European countries intwo main activity sectors (Industry and Manufacturing) between 1970 and 2018, with a focus on theenergy sector. The method used is the Phillips-Sul log t-test using two ordering criteria to run the algorithmfor the panel countries. The first one is using the last observation and the second one uses thesample average. The results of analyses of data strongly support the existence of convergence clubs,indicating that five groups of European countries are converging to distinct steady states for theaggregate CO2 emissions. We also find evidence of convergence clubs for industry sectors whilemanufacturing sector shows clubs convergence only when we use the first criterion while in the secondcase, we find only a single steady state.
