摘要

这项研究量化了欧盟可再生能源指令(RED)对葡萄牙运输部门采用生物燃料的影响。为此,本研究使用带有两个互补计量经济学规范的矢量误差修正模型,分析了监管工具与市场动态之间的相互作用。第一个规范通过评估先进生物燃料证书(TdB)的发放如何响应农业和能源市场价格,抓住了证书市场的行政层面。第二个规范侧重于生物燃料的物理合并,并检查化石燃料库存、总储量和低碳燃料融入能源结构之间的关系。方差分解表明,柴油是影响TdB发行的主要因素(19.14%),其次是乙醇(12.75%)和馏分油(4.51%)。农产品价格的影响较小,但在不断扩大(大豆:2.94%,棕榈:4.44%,油菜籽:3.51%)。低碳燃料的纳入主要取决于化石燃料库存,特别是汽油(11.59%)和馏分油(7.28%)。这项研究为农产品价格、化石燃料和监管机制之间的相互作用提供了新的证据,突出了RED措施如何应对市场波动,并有助于应对能源转型的更广泛挑战。

Biofuel adoption in the transport sector: The impact of renewable energy policies
This study quantifies the impact of the European Union’s Renewable Energy Directive (RED) on the adoption of biofuels in Portugal’s transportation sector. To this end, the study analyzes the interaction between regulatory instruments and market dynamics using a vector error correction model with two complementary econometric specifications. The first specification captures the administrative dimension of the certificate market by assessing how the issuance of advanced biofuel certificates (TdB) respond to agricultural and energy market prices. The second specification focuses on the physical incorporation of biofuels and examines the relationships among fossil fuel stocks, TdB, and the integration of low-carbon fuels into the energy mix.
Variance decomposition shows that diesel is the main factor influencing TdB issuance (19.14%), followed by ethanol (12.75%) and distillates (4.51%). Agricultural commodity prices have a smaller but growing impact (soy: 2.94%, palm: 4.44%, rapeseed: 3.51%). The incorporation of low-carbon fuels remains primarily determined by fossil fuel inventories, especially gasoline (11.59%) and distillates (7.28%).
This study provides new evidence on the interaction between agricultural commodities prices, fossil fuels, and regulatory mechanisms, highlighting how RED measures respond to market fluctuations and contribute to the broader challenges of the energy transition.
