On the persistence of shocks to global CO2 emissions: a historical data perspective (0 to 2014)

Anthropogenic emissions of carbon dioxide (CO 2 ) are the most important greenhouse gas. However, until now, no research has investigated the persistence of global CO 2 emissions over a very long period of time. This work aims to fill this gap by examining the persistence of shocks to global CO 2 em...

Description
Summary:Anthropogenic emissions of carbon dioxide (CO 2 ) are the most important greenhouse gas. However, until now, no research has investigated the persistence of global CO 2 emissions over a very long period of time. This work aims to fill this gap by examining the persistence of shocks to global CO 2 emissions with a dataset of more than 2000 years. To this end, the study applies a battery of unit root tests by considering sharp and smooth structural shifts as well as the frequency domain properties of the series. Lee-Strazicich method results reveal that sharp break dates relate to the influenza pandemic of 1557 and the invention of the steam engine in 1712, and these historical events led to changes in the trend function of CO 2 emissions. The findings of the Fourier Lagrange Multiplier and Fourier wavelet unit root tests illustrate that global CO 2 emissions contain a unit root and do not exhibit mean-reverting behavior, thus external shocks have permanent effects on CO 2 emissions. The results suggest that a reduction in global CO 2 emissions is possible if effective environmental and energy policies established in international meetings such as Rio Conference, Kyoto Protocol Paris Agreement, and the United Nations Sustainable Development Summit are properly implemented.
