The Policy Instrument Database provides a structured overview of policy measures supporting renewable fuels and bioenergy across Europe. It brings together information on regulations, incentives, support schemes, strategies, and other policy instruments at European and national levels, helping stakeholders better understand the evolving policy landscape. The database is designed to support policymakers, researchers, industry actors, and project developers in identifying relevant policy frameworks, comparing approaches across countries, and tracking developments that influence the deployment of renewable fuels and bioenergy solutions.
