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.
The African Human Capital Data Sheet 2026: Past Trends, Skills, and Future Pathways presents new evidence on population trends by level of education, skills, and demographic transitions across the African continent.
Tropical forests are one of the planet's most important carbon sinks – often also called "the lungs of the Earth". But their future in a high-CO₂ world remains uncertain. IIASA researchers contributed to a new study, which suggests even small understory trees in the Amazon may initially buffer climate change more strongly. Their long-term capacity to store carbon could, however, be restricted by nutrient availability, highlighting the vulnerability of these ecosystems under future climate conditions.
Within the framework of the International Vienna Energy and Climate Forum (IVECF) 2026, CircEUlar researchers Volker Krey (IIASA), Alessio Mastrucci (IIASA), Adriana Gomez Sanabria (IIASA), and Dominik Wiedenhofer (BOKU) convened a high-level Deep Dive session titled “Integrated green industrialisation strategies across the energy, material and climate nexus to achieve climate and development goals” on 10 April. The session brought together representatives from policy, industry, finance, international organisations, and research.
A high-level delegation led by Senator Hon. Jonathan Reid, Barbados' Minister of Innovation, Industry, Science, and Technology, visited Schloss Laxenburg for a bilateral exchange with IIASA Director General Hans Joachim (John) Schellnhuber on applied systems science and its potential to inform transformative policy.
IIASA is pleased to announce that Susie Kitchens will join the Institute as Science Diplomacy Director and Head of Communications and External Relations in May 2026. In this senior leadership role, she will guide IIASA’s global engagement strategy, expand international partnerships, and enhance the Institute’s visibility and impact at the science-policy-society interface.
IIASA had the honor of welcoming H.E. Mr. Dong Baotong, Vice Minister of China’s Ministry of Ecology and Environment (MEE) and Administrator of the National Nuclear Safety Administration (NNSA), to Schloss Laxenburg on Wednesday, 15 April 2026. The visit marked the first time a Vice Minister of MEE visited IIASA, highlighting the importance of science-based dialogue in addressing global environmental challenges.
Earlier this week, IIASA welcomed a delegation from the Organization for Security and Co-operation in Europe (OSCE) to Schloss Laxenburg for a high-level exchange on advancing collaboration at the intersection of science, policy, and emerging technologies.
Rising living costs, energy insecurity, widening inequality, and escalating climate impacts are fueling discussions on fairness and justice in climate policy. Yet, assumptions in global emission scenarios that determine who benefits and who bears the costs are often only made implicitly. A new IIASA-led study addresses this gap by offering a practical way to assess and design emission scenarios that explicitly account for distributive justice.
A new IIASA-led study finds that expanding street green space can reduce urban heat stress in cities worldwide, but even ambitious greening efforts are unlikely to offset a significant share of the additional heat expected under climate change. Instead, the research shows that street greenery should be part of a broader portfolio of urban adaptation measures.
IIASA researchers have been working with the Climate and Clean Air Coalition (CCAC), Stellenbosch University, and the African Centre for Clean Air, to provide financial and technical support to Uganda, through its National Environment Management Authority (NEMA), to develop the Uganda Sector Strategy for Organic Waste Management.
New insights from four NATURANCE Innovation Labs show how risk transfer and nature-based solutions can work hand in hand to address escalating climate risks. From flood resilience in the UK and Italy to wildfire and urban heat challenges across Europe, the brief highlights practical opportunities to scale NbS where they are needed most.
On Tuesday, 17 March 2026, IIASA had the privilege of hosting Austrian Federal President Alexander Van der Bellen at Schloss Laxenburg for a program focused on exchange, conversation, and engagement with the Institute’s research community. Austria is IIASA’s host country and one of its founding members, with its membership dating back to 1973.
The Horizon Europe project CHOICE hosted an online webinar presenting two interactive simulation environments designed to make food-system and climate modelling more accessible to stakeholders, policymakers, and non-expert users. The session featured live demonstrations and hands-on exercises exploring how behavioral change, dietary shifts, food waste reduction, and land-use decisions can shape sustainability outcomes.
During a recent visit to Brazil, IIASA Director General, Hans Joachim (John) Schellnhuber, and Deputy Director General, Karen Lips, met with representatives from government agencies, research institutes, universities, and NGOs to explore opportunities for collaboration on some of the world’s most pressing sustainability challenges.
Two new studies published in leading scientific journals conclude that stabilizing long-term climate risks will require sustained net-negative carbon dioxide (CO₂) emissions for centuries. Approaching the problem from distinct perspectives – legal and technological feasibility on the one hand, and economic optimization under uncertainty on the other – the research converges on a consistent message: reaching net zero is not enough.
