Headline: Systemic Interdependencies: Nature, Technology, Society

The coronavirus pandemic has created enormous social, economic and political challenges worldwide. The demand for immediate action often pushed climate policy ambitions into the background. Scientists from the University of Waterloo (Canada), together with Ortwin Renn from the IASS and Hans Joachim Schellnhuber of PIK have developed a new operational approach that provides guidance to decision-makers seeking to reconcile the demands of competing goals, including effective climate protection.

Plastic waste is considered one of the biggest environmental problems of our time. IASS researchers surveyed consumers in Germany about their use of plastic packaging. Their research reveals that fundamental changes in infrastructures and lifestyles, as well as cultural and economic transformation processes, are needed to make zero-waste shopping the norm.

Would humanity be helped by deploying technologies to modify solar radiation in such a way as to slow global warming, while also creating complex problems? A team of researchers with participation from the IASS has reviewed the current state of knowledge on solar radiation modification. The resulting study offers an overview of how geo-engineering interventions could affect efforts to achieve the SDGs.

The coronavirus pandemic has disrupted efforts to achieve the United Nations Sustainable Development Goals (SDGs) and in some cases stalled progress decades in the making. The pandemic has revealed social inequalities and widened the gulf between countries. In a new study published by the IASS a team of Alexander von Humboldt Climate Protection Fellows analyses the effects of the pandemic on climate mitigation and sustainable development in the Global South.

Summer is the ozone season: The harmful gas forms at ground-level on hot, sunny days. In recent years, however, the rise in ozone levels over the summer months has not been as pronounced in Germany as it was previously. According to a new study, this is primarily due to a reduction in nitrogen oxide emissions. This trend can be observed across Germany’s southwestern regions in particular, while Berlin lags behind.

Digitalisation can support transitions towards a more sustainable society if technologies and processes are designed in line with suitable criteria. This requires a systemic focus on the risks and benefits of digital technologies across the three dimensions of sustainable development: the environment, society, and the economy. This is the conclusion of a study prepared by a team of researchers at the Institute for Advanced Sustainability Studies (IASS) in Potsdam. Applying this precautionary approach to digitalisation requires the active involvement of developers, users, and regulators.

The precautionary principle aims to anticipate and prevent hazards to the environment and human health from arising. It plays an important role in environmental and consumer protection and in the regulation of domestic markets, for example in the approval of products and processes. The challenge of reconciling this principle with efforts to foster innovation is the subject of ongoing debate in European politics and business communities. Researchers at the IASS have now presented their findings to the European Commission.

Globalization, digitalization, sustainabilization – three major waves of transformation are unfolding around the world. The social upheaval caused by these transformation processes has given rise to populist movements that endanger social harmony and threaten democratic values. What rules and institutions can promote stability in the face of such systemic risks? A new study published by the IASS offers some surprising answers.

Systemic risks like climate change, cyber security and pandemics are characterised by high complexity, uncertainty, ambiguity, and effects beyond the system in which they originate. That’s why novel research approaches and regulatory measures are indispensable for the evaluation and management of these risks. An interdisciplinary team around IASS Scientific Director Ortwin Renn recently published a paper on this subject, which appears as the first article in a special issue of the journal “Risk Analysis” edited by Renn and IASS Research Group Leader Pia-Johanna Schweizer.

The international community's current plans to reduce greenhouse gas emissions do not go far enough to curb global warming. As a result, many governments are considering the use of so-called "negative emissions technologies" that would remove carbon dioxide from the atmosphere and sequester the captured emissions. A new study outlines some of the strategies available to open up the current debate around these emerging technologies with the aim of developing a responsible regulatory framework for their use.

The British House of Lords recently invited the Scientific Director of the Institute for Advanced Sustainability Studies (IASS) Professor Ortwin Renn to speak about national risk assessment at a public hearing of the Select Committee on Risk Assessment and Risk Planning. One of the main points Renn made to the British Parliament was that in tackling a national crisis, governments need to show that they are working in the interests of the common good.

How can digitalisation serve sustainable development? At the Digital Summit hosted by the Federal Ministry for Economic Affairs and Energy, Ortwin Renn presented a paper outlining concrete steps to improve the sustainability of the digital transition.

Faced with the challenges of digitalization and the climate crisis, many companies are keen to improve their sustainability. In a new study, researchers examine the potential uses of data analysis to strengthen corporate environmental management in the automotive industry. The study reveals that Big Data could enhance corporate environmental management in a variety of ways and that many of these opportunities are going untapped.

Climate change is gaining prominence as a political and public priority. But many ambitious climate action plans foresee the use of climate engineering technologies whose risks are insufficiently understood. In a new publication, IASS researchers describe how evolving modelling practices are trending towards “best-case” projections.

The threat posed by ozone to human health and vegetation continues to be a matter of concern for German politicians, scientists, and the general public. Participants in a workshop organised by the Institute for Advanced Sustainability Studies (IASS) and the German Environment Agency (UBA) analysed the current state of knowledge on ozone and identified areas where more action is required. The resulting publication contains a catalogue of recommendations for tackling the ozone problem.

The coronavirus pandemic has cast a spotlight on the vulnerability of global value chains. Sustainable value chains at the regional level could bring more stability to the post-pandemic world. A team of researchers at the Institute for Advanced Sustainability Studies (IASS) has developed a typology of climate win-win strategies that can be used to identify sustainable regional value chains.

Although there were early warnings of an exponentially growing pandemic, most policymakers around the world were unprepared and reluctant to act when Covid-19 first spread from China around the world. Since then the crisis has led to unprecedented restrictions and triggered the worst recession since the Second World War. In an article published in the Journal of Risk Research, Aengus Collins, Marie-Valentine Florin (both EPFL International Risk Governance Center) and IASS Scientific Director Ortwin Renn analyze the key factors and offer recommendations on how we can better prepare for future crises.

Supply chains collapse, companies are facing bankruptcy, and mass unemployment ensues. Covid-19 has triggered a global financial crisis and is forcing states to develop rescue packages on a scale not seen before. In addition, the crisis has called into question the US dollar's hegemony and could redefine the global monetary system. A team of researchers from the Institute for Advanced Sustainability Studies (IASS) has developed four scenarios that show how political decisions will shape the post-Corona world.

Today, more than ever, politicians rely on sound scientific advice to make decisions. The political issues that most need scientific input are those where the science itself is often complex and uncertain. A SAPEA working group under the leadership of Ortwin Renn has developed proposals for good scientific advice.

Eighteen people were recently awarded the Order of Merit of the federal state of Baden-Württemberg by Governor Winfried Kretschmann. Professor Ortwin Renn, Scientific Director at the Institute for Advanced Sustainability Studies (IASS) was among them. Renn was honoured for his outstanding contribution to the transfer of scientific insights into politics, public administration and management and his unstinting commitment to a just and sustainable economic and social order.

Populations are growing in disaster-prone areas around the world. The interaction of natural hazards with physical infrastructure in these regions can trigger devastating chain reactions, harming societies and their technical foundations. What can be done to address these challenges? A team at the Institute for Advanced Sustainability Studies (IASS) has developed a multi-level risk governance concept for natural disasters.

Digitalisation is changing how we live, but not only for the better: In addition to giving rise to new products, opportunities and services, it’s also having unintended side effects. The project “Digital Data as a Subject of Transdisciplinary Processes” (DiDaT) focuses on both the opportunities and the undesired consequences of digitalisation. It aims to identify and analyse side effects and make concrete proposals for coping with them. At an event to kick-start the project at the end of March, researchers and practitioners came together in Potsdam to define the main areas the project will focus on and outline potential solutions.

“Green growth” promises to foster sustainable development while promoting economic prosperity and advancing social justice. But how does this work in practice? The EU-funded research project “Green Growth and Win-Win Strategies for Sustainable Climate Action” (Green-Win) has studied a range of green growth strategies. Its research results include a new guide to green business models and policy recommendations to foster green growth and support small and medium-sized enterprises.

Cities are more vulnerable than rural areas to a host of risks. Natural hazards like earthquakes or social risks like vandalism and crime have a far greater impact there. Moreover, the infrastructure of our cities is increasingly networked, and while smart cities may offer more in terms of security and convenience, data protection often falls by the wayside. Since risks are frequently interconnected, we need to take an integrated approach to managing them. A concept for risk governance elaborated by IASS researchers in the International Journal of Disaster Risk Science reflects just such an approach.

IASS Director Ortwin Renn spoke about the current challenges of sustainability policy in an address to the Parliamentary Committee on Sustainable Development on 13 June.

How powerful is fear and what effect does it have on our society? These questions are at the heart of a recently published book by the environmental and technical sociologist Ortwin Renn. In “Zeit der Verunsicherung” (Anxious Times), the Scientific Director at the Institute for Advanced Sustainability Studies (IASS) probes the causes and effects, as well as the perception and handling of fears in our society.
