Reza Maddahi
Dr.Reza Maddahi, PhD in Law
Reza Maddahi is an Iranian–Finnish legal scholar whose research focuses on international environmental law, climate change governance, and carbon capture and storage (CCS) regulation. He is a doctoral researcher at the University of Eastern Finland (UEF), where his dissertation examines the European Union’s legal regime governing carbon capture and storage, including interactions between the CCS Directive, the EU Emissions Trading System, and emerging industrial carbon management frameworks.
Maddahi’s work contributes to debates on subsurface governance, liability allocation, and the legal architecture required to support large-scale carbon management projects within the European Union. His publications explore mineralization-based CO₂ storage, its regulatory treatment under EU climate law, and the broader challenges of integrating novel carbon removal technologies into existing environmental legislation.
Early life and education
Maddahi completed his Bachelor of Laws (LL.B.) and Master of Laws (LL.M.) degrees in Iran, where he specialized in public international law. He later moved to Finland to pursue doctoral studies at the University of Eastern Finland. As part of his PhD, he has conducted research across European regulatory and policy institutions and participated in scholarly networks on climate change law and energy governance.
Academic career
Maddahi is a PhD researcher at the Center for Climate, Energy and Environmental Law (CCEEL) at UEF[1]. His academic work focuses on the legal dimensions of carbon capture, utilization, and storage (CCUS), with a particular emphasis on:
Regulatory fragmentation in the EU CCS framework
Liability and long-term stewardship in geological storage
The relationship between CCS and EU emissions trading
Subsurface governance and mineralization technologies
Risks and governance gaps in emerging carbon dioxide removal (CDR) methods
He has presented his research at international academic conferences, workshops on climate governance, and expert meetings related to EU climate and industrial policy.[2]
Research and publications
Maddahi’s peer-reviewed publications address the evolving legal structure of CCS and CO₂ mineralization within the European Union. His notable works include:
Carbon dioxide utilization and storage through mineralization under European Union law: a legal analysis of the EU CCS Directive and the EU Emissions Trading System, co-authored with Kim Talus[3]. This article examines the legal status of mineralization technologies and evaluates their alignment with existing EU climate legislation.
Articles and reports analyzing EU-wide liability frameworks, the potential for harmonized subsurface governance, and proposals for an “ENTSO-C”—a conceptual European network operator for carbon—designed to coordinate cross-border CO₂ transport and storage.
His scholarship frequently engages with interdisciplinary perspectives, incorporating geoscience, economics, and climate policy to illuminate the legal dimensions of carbon management.
Research interests
Maddahi’s primary research interests include:
International environmental law
EU climate and energy law
Subsurface and geological storage governance
Carbon capture, utilization, and storage (CCUS)
Carbon dioxide removal (CDR) and mineralization
Net-zero regulatory architectures
He is especially known for his analysis of the EU’s CCS Directive and its regulatory implications for emerging industrial carbon management systems.
Professional affiliations and activities
Maddahi is active within European research networks focused on climate law, industrial decarbonization, and energy transition policy. At UEF’s CCEEL, he collaborates with researchers working on climate governance, the EU Green Deal, and comparative climate regulation. He engages with policymakers, legal practitioners, and scientific experts in CCS and subsurface engineering through workshops and research projects.
