Resumen de Driving factors of GHG emissions in EU transport activity
Lidia Andrés Delgado, Emilio Padilla
This research identifies the driving factors of greenhouse gas emissions in transport activity in the EU-28 and the contribution of each of them to its changes during the period 1990–2014. The analysis is based on the STIRPAT model, which is broadened to investigate in depth the impact on transport emissions of changes in the transport activity and in the whole economy. In short, the study takes into account the population, economic activity, transport volume, transport energy intensity and structural composition of transport activity in terms of transport modes' share and of energy sources' mix. Using panel data econometric techniques, the significance of each factor and the impact of its change on emissions are identified. A better knowledge of the key driving forces is crucial for implementing policies focused on successfully reducing emissions in transport activity. The results allow a preliminary assessment of the potential effectiveness of the 2011 Transport White Paper measures aimed at cutting transport emissions.
