Inequality in carbon intensity in EU-28: analysis based on club convergence.

This study examines the convergence properties of CO intensity in EU-28 countries, using panel data for the period 1990 to 2016. We use Phillips and Sul's (2007) approach to test for CO intensity convergence and identify convergence clubs. In addition to the EU-28 members, we analyze the EU-15, and the new EU members (EU-new) that joined after 2004, as distinct groups for the periods 1990-2016, 1990-2004, and 2005-2016.
