Abstract
CO 2 emissions per capita (Emc) and CO 2 emissions intensity (Emint) are among the main metrics used to report emissions in environmental studies. The main aim of this note is to compare the evolution of Emc and Emint in the G19 countries. Comparing their varying trends is useful in benchmark analysis. Indeed, in our study of the G19 countries, we offer evidence that such metrics show different trends for the same group of countries both at the sample and the individual level. Using a growth curve modeling approach, we find that Emint has been decreasing in the G19 countries while Emc has been increasing, but at a slower pace. Further, countries with high initial Emint have achieved the greatest reduction in the period analyzed, whereas there is no evidence of such a change in the case of countries with high initial Emc. We also find that a country’s area affects its Emint growth, but not its Emc. Used together, Emint and Emc offer better insights into environmental performance as measured through these metrics.

Summary
The reduction of future CO2 emissions at a global level is one of the main goals of mitigating climate change effects. The two main metrics used are emissions per capita (Emc) and emissions intensity (Emint). The former represents the total country CO2 emissions per capita (in metric ton of CO2). The analysis of the convergence of CO2 Emint has received little attention among economists (Zhao et al, 2015), Emint as a metric for allocation of emissions mitigation has been advocated in different studies such as Rowlands (1997) and Winkler et al (2002). The G19 countries are Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, South Korea, Mexico, Russia, Saudi Arabia, South Africa, Turkey, United Kingdom, and United States. We condition the growth rates of emissions on the corresponding country areas
