Research on the Relationship between CO2 Emissions, Road Transport, Economic Growth and Energy Consumption on the Example of the Visegrad Group Countries

Abstract

This study examines the cointegration and short- and long-run causal relationships between economic growth and CO2 emissions, fuel consumption and the amount of freight transported by road transport in the Visegrad Group countries between 1990 and 2019. The autoregressive distributed lag (ARDL) bound testing methodology was used to develop the results for each tested dependent variable. The results confirmed a long-run cointegration between economic growth and fuel consumption by road transport in the Czech Republic and Slovakia. In addition, a long-run relationship between economic growth and freight volume and CO2 emissions by transport was demonstrated for Slovakia. For Poland, there was only a long-run relationship between energy consumption by road freight transport and CO2 emissions. In the short run, relationships were shown between the volume of freight transported by the road freight transport sector and CO2 emissions for Hungary and Poland. Short-run relationships between economic growth and the volume of freight transported in Poland, the Czech Republic and Hungary are also interesting observations. The obtained results expand the information resources needed to make decisions on the direction of change in road transport. Additionally, the results can be used to prepare a proper environmental policy for road freight transport within the framework of the European Green Deal.
