Architecture 2030 is calling on all architects, engineers, planners, and individuals involved in the building sector worldwide to design all new projects, renovations, landscapes, cityscapes, and infrastructure to be zero carbon starting now.
Prolonged heatwaves have been increasingly common in recent years, and cities are devising various strategies for combating the urban heat island effect. As Sydney experienced blistering summer temperatures of up to 50 degrees Celsius, the authorities have recently banned dark roofs on new homes and mandated lighter-coloured alternatives to reflect solar radiation. In Europe, Athens has taken the example of Miami and hired a Chief Heat Officer, tasked with finding coping strategies as the city confronts with heatwaves and wildfires that prompted a large number of residents to vacate the capital.
By some estimates, cities consume over two-thirds of the world’s energy, and account for more than 70% of global CO2 emissions: a figure sure to increase as the global migration from rural to urban areas continues. In the pursuit of exploring new models for how healthy cities could more effectively sustain these demands, Dutch design and research studio FABRICations has investigated how cities of the Netherlands can reduce carbon emissions through new design-led approaches.
The climate has changed, and we have been left grappling with the consequences: high temperatures, flooding, drought and much more. As the world shifts (or tries to shift) to ways to mitigate the crisis, the architecture and construction industry finds itself in a particularly important position whose choices can create real impact. Some of these choices can include innovative products that offer real solutions to complex problems, such as the cooling down of temperatures in highly dense cities.

The "Climate Emergency" continues to embody a renewed worldwide focus on tackling climate change. While there is no "one solution" to the multifaceted challenges brought about by this crisis, there is an onus on every citizen, in both a personal and professional capacity, to apply their skills and actions in addressing the profound pressures on the natural world.
For those involved in the design of buildings and cities, be they architects, urbanists, or citizens, there is a deep responsibility to be aware of, and design for, the impact of climate change. With 36% of global energy devoted to buildings and 8% of global emissions caused by cement alone, the architectural community is deeply entwined with the flows of materials, energy, and ideas that relate to climate change, both causes, and solutions.
A new report from the Intergovernmental Panel on Climate Change (IPCC) states that global warming of 1.5°C (2.7 °F) is essentially inevitable in coming decades. The question now is whether the world can prevent further, more destructive warming of 2°C (3.6°F), or, even worse, 3°C (5.4°F), which is what current policies put us on a trajectory to experience. Our economies can only put another 420 gigatons of greenhouse gas emissions into the atmosphere if we want a good chance of keeping a temperature increase to 1.5°C instead of 2°C. At our current pace, the world’s carbon budget will be used up before 2030. We need to phase out fossil-fuel use, build thousands of new clean power plants -- and swiftly move to power our homes, offices, schools, and transportation systems with clean energy.
According to data from CRED (Centre for Research on the Epidemiology of Disasters) and UNISDR (UN Office for Disaster Risk Reduction), in a report released in 2016, the number of disasters related to the climate change has duplicated in the last forty years. The need for temporary shelters for homeless people is, as well as an effect of the climate crisis, is also one of the consequences of the disorderly growth of cities, which leads to a significant part of the world population living in vulnerable conditions due to disasters.

Climatic conditions throughout the world are changing and with extreme temperatures and scarce resources becoming the norm, architectural materials and techniques are having to innovate to prepare for the future.
'Carbon to Rock' is an installation by IGNEOUS TECTONICS (Cristina Parreño and Sergio Araya) being presented in the 2021 Venice Biennale that highlights volcanic rock as a promising material in the global push to mitigate climate change.
The Intergovernmental Panel on Climate Change, the UN's body for assessing the science related to climate change, has recently published a comprehensive report documenting the extent of global warming. The paper provides new time estimates for crossing the 1.5 degrees Celsius threshold, urging immediate and large-scale action to reduce greenhouse gas emissions. Following the publication of the report, UK Architects Declare has issued a statement inviting decision makers to a dialogue on how to collectively address the climate crisis while at the same time calling for the design professionals to re-evaluate their practice to support meaningful change.
Recent extreme weather events and the acceleration of climate change, paired with decarbonization efforts that are not on track, make climate-related disruption unavoidable for urban environments, raising the issue of climate-risk adaptation. Moving past what can be done to prevent climate change, there is a strong imperative to develop strategies to prepare urban environments to cope with inevitable challenges such as sea-level rise, floods, water scarcity or extreme heat. The following discusses how cities can build resilience and adapt to undergoing and expected future climate threats.
When we think of migration, we think of movement. We think of the movement of people simply looking for greener pastures – a better life for themselves. But we also think of war, of conflict, of an unstable situation in a specific place forcing the hand of a location’s residents to seek safety elsewhere. Historically and into present day, war has been the reason for the increased presence of refugees. Instability in places such as Syria, Iraq, or the Central African Republic have caused millions to flee their homes. Lurking amongst this migration due to conflict, however, is the migration of people at mercy of the changing environmental conditions of the Earth – climate migration.
Recently, a series of cities and government entities worldwide have announced various plans to either fight climate change or combat its effects. From New York’s investment in carbon-capturing technologies to Miami’s Stormwater Masterplan, or EU’s target to reduce emissions by 55% by 2030, the issue begins to take centre stage in urban design and politics. The measures come at a time when the consequences of climate change are becoming more apparent in extreme weather events, and the scientific forecast is less than optimistic.
Earlier this month, the city of Miami released a draft version of its comprehensive plan to combat the effects of climate change. The so-called Stormwater Master Plan (SWMP) will be implemented to alleviate the threat of flooding throughout the city, improve the quality of water in Biscayne Bay, and fortify its coastline against stronger and more frequent storm surges over the next 40 years, at an overall cost estimate of $3.8 billion.
Throughout the world's cities, in the midst of current and projected crises-- environmental, health, economic, and otherwise--one question looms: How can we prepare our urban centers' most vulnerable sectors?
Current data paints a bleak picture of cities and the impact of climate change. With urban populations skyrocketing as people around the globe seek opportunities for a better life in the world's urban centers, cities have become gluttons for energy and other resources while simultaneously producing more emissions than ever before. On top of this, 3 out of 5 cities are at high risk for natural disasters.

In this week's reprint, Martin C. Pedersen talks with John Englander, author of Moving to Higher Ground: Rising Sea Level and the Path Forward, about the “unstoppable” sea-level rise. The article explores the importance of planning for this challenge right away. In fact, "we have some time, but not all the time in the world" states John Englander.
Across the globe, tall wood structures have begun transforming the world of skyscrapers and high-rise buildings, ushering in an important shift to an architectural practice that has traditionally been dominated by steel and concrete. Typically defined as wood-constructed buildings over 14 stories or 50 meters high, the past six years have seen over 44 tall wood buildings built or underway around the world. Notable examples include Michael Green Architecture and DLR Group’s T3 and Team V Architectuur’s upcoming 73 meter residential tower HAUT.
For this month, The Dirt and author Jared Green share with us a study about urban heat islands, exploring new approaches that have been designed to both reduce urban temperatures and help communities adapt to a hotter world, In three cities: New York City, Copenhagen, and Abu Dhabi.
The 17th Venice Architecture Biennale is currently unfolding, revealing a wide range of answers to the question "How will we live together". With 60 national pavilions, numerous contributions of invited architects from all around the world and several collateral events, this year's edition restates the Biennale's role as a platform for inquiry, exploration, and disruptive thinking in architecture. Curator Hashim Sarkis' original statement called upon architects "to imagine spaces in which we can generously live together." Recent circumstances have made the question even more relevant, prompting a holistic re-evaluation of how the world as a collective can face changes and challenges of an unprecedented scale from the disrupting role of technology, to inequality, mass migration and climate change. The following national contributions reflect on "how will we live together" amidst climate change, exploring ideas for a more sustainable future.
