Economic growth increases greenhouse gas (GHG) emissions in EU road freight. Improving transport energy efficiency reduces emissions and partially offsets growth impacts, especially with green policies.
Area of Science:
- Environmental Science
- Transport Economics
- Climate Policy
Background:
- Road freight transport is a significant source of greenhouse gas (GHG) emissions in the European Union.
- The interplay between economic growth, transport energy efficiency, and emissions in freight transport, considering country-specific factors, is not fully understood.
Purpose of the Study:
- To empirically investigate the direct and indirect relationships between economic growth, transport energy-use performance, and GHG emissions in the EU road freight sector.
- To analyze cross-country heterogeneity in environmental conditions and climate policies affecting these relationships.
Main Methods:
- Utilized panel data for 24 EU countries from 1990-2021.
- Applied Dynamic Common Correlated Effects (DCCE) models, clustering, and mediation analysis.
- Accounted for cross-country heterogeneity and transmission mechanisms.
Main Results:
- Economic growth was found to significantly increase GHG emissions.
- Enhanced transport energy-use performance led to emission reductions, particularly in countries with lower environmental advancement.
- Improved energy performance partially mediated the impact of economic growth on emissions.
- The growth-emission link was weaker in countries with advanced green transport policies, indicating partial decoupling.
Conclusions:
- Economic growth alone is insufficient for emission reduction in road freight.
- Decarbonization requires a dual approach: technological advancements and robust policies (e.g., environmental taxation, fleet modernization) to boost energy efficiency and lower emission intensity.
