This paper re-examines the environmental Kuznets curve (EKC) for CO2 emissions. In order to adhere to the EKC story, CO2 emissions are taken in absolute rather than in per capita terms. We employ both parametric and semi-parametric methods. Our dataset includes 142 countries for the period 1971-2007.The robustness of cross-country analysis is checked first by focusing on a subsample which excludes potential outliers, and then by looking both at the world as a whole and at country patterns. Our findings confirm the importance of robustness exercises, supporting the idea that the evidence in favour of a CO2-EKC, if any, is a statistical artefact.

Abstract
This paper re-examines the environmental Kuznets curve (EKC) for CO2 emissions. In order to adhere to the EKC story, CO2 emissions are taken in absolute rather than in per capita terms. We employ both parametric and semi-parametric methods. Our dataset includes 142 countries for the period 1971-2007.The robustness of cross-country analysis is checked first by focusing on a subsample which excludes potential outliers, and then by looking both at the world as a whole and at country patterns. Our findings confirm the importance of robustness exercises, supporting the idea that the evidence in favour of a CO2-EKC, if any, is a statistical artefact.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
