Summary

Greece’s Law 3908/2011 provides investment incentives that emphasise environmental protection, energy efficiency, and green innovation. Companies must meet strict eligibility, reporting, and implementation obligations, with audits verifying progress. Failure to deliver milestones or environmental benefits can trigger repayment or sanctions. Although new laws have updated the scheme, Law 3908/2011 continues to govern legacy-supported investments and forms part of Greece’s broader green industrial policy.

What’s Required

Law 3908/2011 establishes Greece’s modern investment incentives framework, including substantial support for green, low-carbon, energy-efficient, and environmentally upgrading projects.

The law provides:

  • Grants, tax exemptions, leasing subsidies, and wage subsidies to support eligible investments.

  • Priority incentives for environmental protection, circular economy, renewable energy, energy efficiency, low-carbon manufacturing, and innovation.

  • Requirements for investors to submit feasibility studies, environmental documentation, and financial plans.

  • Mandatory compliance with EU state-aid regulations and national verification procedures.

  • Monitoring obligations to ensure that funded projects deliver the promised economic, environmental, and energy-efficiency outcomes.

Important Deadlines

  • Law in force since 2011, with multiple amendments and investment “cycles”.

  • Approved projects must meet implementation milestones typically within 2–5 years.

  • Ongoing updates via subsequent investment laws (e.g., Law 4399/2016 and Law 4887/2022) retain and expand green-investment principles.

Current Status

Although replaced by newer incentives laws, Law 3908/2011 still governs legacy approved projects and remains an important reference for Greece’s green-investment regulatory evolution. Environmental performance remains a central criterion in all successor frameworks.

Penalties

  • Repayment of grants or subsidies for non-implementation or false declarations.

  • Withdrawal of project approval for major deviations from environmental or financial obligations.

  • Administrative fines and exclusion from future incentives.

Examples of Known Violations

  • Cases where companies failed to complete projects on time and were required to repay financial aid.

  • Audit findings on insufficient environmental performance relative to commitments.
