IIASA is pleased to announce the winners of the 2025 Young Scientists Summer Program (YSSP) Awards in recognition of outstanding research conducted during the program.

Each year, the YSSP Awards honor participants who have demonstrated exceptional creativity, scientific rigor, and relevance in addressing pressing global challenges. This year, two prestigious awards were once again granted: the Mikhalevich Award and the Levien Award. Additionally, four participants received honorable mentions for their excellent contributions.

IIASA Program: Energy, Climate and Environment (ECE)
Program Director: Keywan Riahi

The Levien Award was granted to Parisa Javadi, a third-year PhD candidate in Civil and Environmental Engineering at the University of Virginia. She is passionate about modeling varying climate mitigation pathways to understand the regional removal potential as well as the environmental, social, and economic implications of different CDR approaches. She won the award for her research titled The Role of Land and Ocean-Based Geochemical CO2 Removal Pathways in Climate Mitigation.

The YSSP Awards highlight IIASA’s commitment to fostering interdisciplinary research and nurturing the next generation of system thinkers. Each winner has made significant contributions to advancing knowledge and addressing real-world challenges in climate change, economics, and sustainability.

“The YSSP Awards honor the exceptional talent and bold innovation of young researchers who are confronting some of the world’s most pressing and complex challenges,” says IIASA Capacity Development and Training Dean, Fabian Wagner. “This year’s awardees have not only advanced scientific knowledge, but have also shown how interdisciplinary collaboration can translate insight into real-world impact. We are proud to support their ongoing efforts to help shape solutions to critical global issues.”

The award winners will receive an award stipend to return to IIASA for a period of up to three months, within 36 months after accepting the award, to continue their YSSP research.

Full fossil fuel phase-out by 2050 would require up to 80% more electricity generation

New research by an international team of scientists finds that fully phasing out fossil fuels worldwide by 2050 would require global electricity generation to expand by roughly 60 to 80% beyond the levels projected in conventional 1.5°C climate pathways. The study also shows that eliminating fossil fuels could significantly reduce dependence on CO2 removal technologies and underground carbon storage.
