Biofuel Adoption in Portugal's Transportation Sector: New Insights into Renewable Energy Policies

Strategic Insights -

Researchers at the University of Coimbra have published a new study on the impact of the European Union's Renewable Energy Directive (RED) on the adoption of biofuels in Portugal's transportation sector. The investigation employed a vector error correction model with two complementary econometric specifications to analyze the interaction between regulatory instruments and market dynamics. The study found that diesel is the main factor influencing the issuance of advanced biofuel certificates, followed by ethanol and distillates.

Key Takeaways:

  • The study analyzed the impact of the European Union's Renewable Energy Directive (RED) on the adoption of biofuels in Portugal's transportation sector.
  • The researchers employed a vector error correction model with two complementary econometric specifications to investigate the interaction between regulatory instruments and market dynamics.
  • The study found that diesel is the main factor influencing the issuance of advanced biofuel certificates, with a 19.14% impact, followed by ethanol (12.75%) and distillates (4.51%).
  • Agricultural commodity prices have a smaller but growing impact on the issuance of advanced biofuel certificates, with soy (2.94%), palm (4.44%), and rapeseed (3.51%) being major contributors.
  • The incorporation of low-carbon fuels remains primarily determined by fossil fuel inventories, especially gasoline (11.59%) and distillates (7.28%).
  • The research concluded that this study provides new evidence on the interaction between agricultural commodities prices, fossil fuels, and regulatory mechanisms.
  • The study highlights how RED measures respond to market fluctuations and contribute to the broader challenges of the energy transition.
  • The research was financially supported by Fundacao para a Ciencia e a Tecnologia (FCT).
  • The study has been peer-reviewed and published in Sustainable Energy Technologies and Assessments.
