Oliver Fricko

Biography

Oliver Fricko joined IIASA in 2012. He is a Senior Research Scholar in the Integrated Assessment and Climate Change (IACC) Research Group of the Energy, Climate, and Environment Program.

He is one of the core developers of the Model for Energy Supply Strategy Alternatives and their General Environmental Impact (MESSAGEix) framework and the lead global modeler of IACC, maintaining and developing the IIASA Integrated Assessment Model (IAM), MESSAGEix-GLOBIOM.
He is involved in numerous multi-model inter-comparison studies which span a broad set of themes centered around assessing global climate mitigation strategies. Some of the most noteworthy projects include:

- Shared Socioeconomic Pathways (SSPs): A set of scenarios covering five different socioeconomic narratives to span varying degrees of global challenges to climate adaptation and mitigation.
- Energy Modeling Forum: EMF-30 which concerned itself with the assessment of short-lived climate forcers on near-term temperature developments, and EMF-33 with the main focused on assessing the role of bioenergy and its impact on land-use in low-temperature scenarios.
- ADVANCE: Developing the next generation of IAMs, exploring climate change mitigation pathways in the context of the Paris Agreement.
- Linking Climate and Development Policies – Leveraging International Networks and Knowledge Sharing (CD-LINKS): Exploration of national and global climate mitigation scenarios to understand their linkage to the Sustainable Development Goals (SDGs).
- Exploring National and Global Actions to reduce Greenhouse gas Emissions (ENGAGE): Policy assessment and development at the global and national level to avoid climate change aimed at maximizing co-benefits and minimizing trade-offs.
- Enabling and Leveraging Climate Actions Towards Net-zero Emissions (ELEVATE): Enhancing the understanding of the Nationally Determined Contributions (NDCs) and the current policies to achieve global net-zero mid-century.

He also acts as a technical advisor to numerous other projects, for example the Network for Greening the Financial System (NGFS) and NAVIGATE. These project scenario contributions were developed based on either scenarios or workflows which Fricko has developed, requiring extensions to suit the specific project needs. Hence his guidance on the usage and adaptation of existing workflows and scenarios helps to ensure that these are used correctly and efficiently. Most recently, he has coordinated the work of more than 30 researchers at IIASA, integrating their contributions and coordinating the development of the scenarios which IIASA contributes to the ScenarioMIP process.

As part of his work, Fricko co-authored over 50 publications and due to the breadth of research and contributions to the diverse research projects, those have been cited close to 10,000 times and with an H-index of 35. He was acknowledged as a Highly Cited Researcher by Clarivate for six subsequent years, from 2020 to 2025.

Fricko developed and maintains the soft linkage between MESSAGEix and the IIASA Global Biosphere Management Model (GLOBIOM) and is currently integrating information on non-CO2 greenhouse gas and pollutant emissions from the Greenhouse Gas and Air Pollution Interactions and Synergies (GAINS) model into MESSAGEix. He developed an approach for incorporating national policies into the global energy model, for example, Nationally Determined Contributions (NDCs) or the net-zero targets and has enhanced the modeling framework to account for energy system wide water requirements.

In addition to the modeling and scenario development work, Fricko has collaborated with various institutions to facilitate capacity development at the national level. For example, he collaborated with several institutions from India such as the National Institution for Transforming India (NITI-Aayog) and TERI-University. Recently, he coordinated and partly implemented IIASA-related work within the Strategic Partnerships for the Implementation of the Paris Agreement (SPIPA)-India project, which aims to support EU-India collaboration on the development of modeling capacities to improve the quality of modeling tools and integrated modeling analysis frameworks developed by modeling teams in India. This was followed by a second project as part of the European Union Climate Dialogues, which deepened the collaboration with Indian Institutions, developing strategies across different sectors to reach the net-zero target of India.
