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.

A new study published in Science argues that governments should adopt three integrated energy demand goals by 2035, warning that climate policy will fall short unless it focuses not only on how energy is produced, but also on how it is used.

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.

As global population aging advances and countries face shrinking workforces, a new study focusing on China by IIASA researchers and colleagues from Nanjing University reveals how economic growth can persist despite these changes in age structures.

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.

On 12 March, a group of interns from the German Agency for International Cooperation (GIZ) visited IIASA to learn about its research activities and interact with its scientists.

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.

The EU agri-food system is increasingly threatened by climate change while accounting for roughly one-third of the EU’s greenhouse gas emissions. A new report by the European Scientific Advisory Board on Climate Change, with contributions from IIASA researchers, warns that current policies are insufficient to address rising climate risks and meet EU climate targets.

Elisa Calliari, a Senior Research Scholar in the Systemic Risk and Resilience Research Group of the IIASA Advancing Systems Analysis Program, has been awarded a prestigious European Research Council (ERC) Starting Grant for a new project investigating how climate change reshapes the habitability of places and how societies respond.

IIASA recently welcomed Distinguished Visiting Fellow Éliane Ubalijoro, CEO of the Center for International Forestry Research and World Agroforestry (CIFOR-ICRAF), for a lecture on the importance of gender and social inclusion in forest and landscape governance and an interdisciplinary discussion on equity and sustainability.

Hands-on mini project- ‘My Future City’ for brainstorming a safer school street for children

Climate change reshapes lives, but not always the way headlines suggest. In this podcast, Roman Hoffmann joined Judith Kohlenberger to explore why most climate‑affected people stay close to home, and what that means for policy and preparedness.
