Advancing Science Communication in an Era of Complex Risk (24 March 2026)
IDEaS recently welcomed Prof. Lisa Palmer, a Journalist in Residence from the International Institute for Applied Systems Analysis (IIASA), for a seminar on “Science Communication in an Age of Complex Risk.”
The session explored a key challenge facing science today: evidence alone does not necessarily lead to action. The seminar highlighted evolving approaches to science communication, including the role of narratives, risk framing, and engagement strategies in bridging the gap between research and societal impact.
A central theme of the discussion was the need to build communities of practice that strengthen communication capabilities across disciplines. Participants reflected on how researchers and journalists can better collaborate to reach broader audiences and enhance the visibility and relevance of scientific work.
The visit sparked ideas for future collaboration between WU and IIASA, reinforcing the importance of effective science communication in addressing complex global challenges.
WU Launches New Course on AI and Environmental Sustainability
March 2026 – The WU Vienna University of Economics and Business has introduced a new bachelor-level seminar, “AI and Environmental Sustainability,” within the Responsible Management of Information Systems (RMIS) specialization.
Offered for the first time in Spring 2026 by IDEaS’ Dr. Zakeri, the course examines the environmental impacts of artificial intelligence, from resource demands of data centres to broader system-wide effects on sustainability. Students critically assess both the risks and opportunities of AI, linking real-world applications to environmental indicators and the United Nations Sustainable Development Goals (SDGs).

Dr. Zakeri delivers a talk on Environmental Impact of DIgitalisation as part of Future Foundations Talk Series (10 November 2025)
The first Future Foundations talk, held on 10 November 2025 in cooperation with WU Vienna University of Economics and Business, focused on the 5th Rule for the Digital World: “Do not destroy life and nature for technical progress.”

Assessing innovation in the nascent value chains of climate-mitigating technologies (August 29, 2025). Kavita Surana co-authored a paper in Environmental Research Letters analyzing nearly 13,000 early-stage investments in over 3,600 North American climate-tech firms between 2006 and 2021. The paper conceptualizes nascent value chains in 14 climate-tech sectors, finding that only 15% of firms develop end products, while the rest support through components, manufacturing, optimization, and business services. Three patterns of innovation emerge—maturing, ongoing, and emerging—with implications for policy design that supports full value chain development rather than only end products.
Impact of energy prices on the decarbonisation of the EU’s building sector [Oct 2024]
The dramatic increase in end-use energy prices in the EU in 2022-2023 has intensified the debate on how these prices may or may not contribute to the decarbonization of the building sector. Dr. Zakeri and a group of researchers from Technical University Vienna (TU Wien) have investigated this question using data-intensive, model-based simulations of all EU Member States’ building sector in 2020-2050. The results underscore that while stringent regulatory measures can achieve significant energy savings and reduce greenhouse gas emissions, they also limit the responsiveness to price signals and as such the impact of prices on the choice of technology.

How can we store hydrogen affordably at a large scale? [Sep 2024]
(Green) hydrogen is considered to be one of the enablers of net-zero energy transitions. As such, many world regions such as the EU have rolled out policies and incentives to scale up hydrogen projects. However, hydrogen storage remains a challenge, especially for long periods (e.g., from summer to winter) and at a large scale. Behnam Zakeri and a group of international researchers explored a new solution for storing hydrogen in lakes and water reservoirs. They estimated potential sites for this new storage solution globally including the cost of storage. The work is published in Nature Communication, including the open access to the accompanying global dataset. More information can be found here: https://www.nature.com/articles/s41467-024-52237-1
