Résumé
This study examines the (non)-stationary properties of the per capita carbon dioxide emissions of 29 selected OECD countries plus Brazil, China, India and South Africa over the period 1960–2014. Following a sequential testing procedure, we analyze the historical path of the variable regarding the possible presence of abrupt ruptures and then carry out appropriate unit root tests. The results show that the CO2 emissions per capita are better characterised by a random walk for all the different countries. Furthermore, the break dates and the growth rate were estimated as well for each country under study. Finally, we decompose the carbon emissions into a secular (or trend) component and a cyclical component, and propose a chronology of cycles in growth rates.
