Circular City Actions Framework – Bringing the Circular Economy to Every City

Current patterns of production and consumption, in particular in the global North, cannot be transferred to the rising world population, in particular in the global South, without severe environmental and societal consequences and economic risks.  The “Green Economy” is intended to “contribute to eradicating poverty as ...

Construction and real estate have been central to the debates on sustainable development. Where the dominant definition of sustainability in the built environment focuses on the environmental dimension, the UN Sustainable Development Goals (SDGs) offer new opportunities for the building sector to expand its focus.  Gre ...

Over the last two decades, the global re/insurance sector has experienced an increasing number of major natural catastrophes, such as winter storms, forest fires, severe heat waves and heavy flooding.  Countries around the world are suffering the effects of climate change, which contribute to more frequent and extreme ...

Climate change is a highly contentious topic that has led to such labels such as “alarmists” and “deniers”.  While the former urge immediate and drastic action to stop global climate change, the latter deny many of the key claims made by scientists about climate change.  Among other, less extreme groups, are the “skept ...

The Vienna Tree Protection Act is considered one of the factors that makes Vienna the “most liveable city” in the world.  While Vienna has a highly effective and strictly enforced tree protection ordinance, the rest of Austria vehemently resists such strict nature conservation measures.  Regulations to protect trees an ...

The global climate is constantly changing and global warming is progressing faster than the best models can cope with.  Assessing the future impact of influencing factors requires hundreds of years of simulations as we move further and further away from the reference points (see “Climate models can't explain what's hap ...

Flooding is increasing due to climate change, urbanization and land-use changes.  Nature-based solutions (NBS) are commonly used as innovative and sustainable methods of flood risk management.  In addition to reducing flood risk, NBS also offer economic and ecological benefits for society and the environment.  However, ...

Mass mobilization driven by the pain and suffering of global climate shocks is expected to be the only way humanity can save itself from the climate crisis we have created.  As the social impacts of climate shocks increase in both frequency and severity, they will trigger an “AnthroShift” in which personal and economic ...

Global climate is constantly changing and global warming is moving faster than the best models can handle.  Assessing the future impact of influencing factors requires hundreds of years of simulations while we are moving further and further away from our reference points.   “We are asking a lot of the models” because m ...

While skepticism is crucial to scientific inquiry and research, the precautionary principle is ambiguous about the distinction between risk and uncertainty.  One challenge for proponents of the precautionary principle is to clarify when evidence that a harmful event could occur is sufficient to consider it a real possi ...

This time, Trump's rejection of global climate efforts could mean a more profound blow as it comes into effect sooner and at a time when the new president has more far-right allies overseas and at home. Promptly after taking office on January 20, President Donald Trump issued an executive order that the US will on ...

Climate change denial rejects, disputes or opposes the scientific consensus on climate change.  Climate change denial includes unfounded doubts about the extent of human-induced climate change, its impact on nature and human society, and the potential for human action to adapt to global warming.  Climate change denial ...

This large-scale survey on the climate anxiety of children and young people globally looks at their attitudes to climate change and its relationship with the perceived government response. It surveyed 10,000 young people aged 16 to 25 in ten countries with 1,000 young people in each. More than half – 56% – said that “h ...

Environmental risks present the greatest deterioration in the findings of the Global Risks Perception Survey 2024-2025, which captures insights from over 900 experts worldwide.  Extreme weather events are anticipated to become even more of a concern, with this risk ranked #1 in the 10-year risk list.  Biodiversity loss ...
