Evidence on CO2 emissions and business cycles

Abstract: CO2 emissions and GDP are positively correlated over the business cycle. Most climate change researchers would agree with the preceding intuitive statement despite the absence of a study that formally analyzes the relationship between emissions and GDP at business cyclefrequencies. The current paper attempts to address this gap in the literature by providing a simple, rigorous and consistent analysis of the relationship in a comprehensive cross country panel. To this end, I decompose the aggregate emissions and GDP series into their growth and cyclical components using the HP filter and focus on the cyclical components. Four robustfacts emerge from this analysis: i) Emissions are procyclical and cyclically more volatile than GDP in a typical country; ii) Cyclical volatility of emissions is negatively correlated with GDP per capita across countries; iii) Procyclicality of emissions is positively correlated with GDP per capita across countries; and iv) The composition of GDP is crucial for the business cycle properties of emissions but the relationship is complex. I undertake and report an extensive set of robustness checks which corroborate these findings. Finally, I propose some preliminarythoughts on the mechanisms that may be generating the data with these properties.
