The City of Vienna launches a Europe-wide ideas competition for the Naschmarkt parking lot. The aim: to steer the deadlocked situation in a new direction. One reason for the deadlock is political. In February 2022, Rosa Schaberl reported on visualizations as a PR tool using the example of Naschmarkt Vienna.

Discussions about visualizations for the parking lot at Naschmarkt Vienna

The 12,000 square meter area next to Vienna’s Naschmarkt is still a dreary concrete surface – a parking lot and one of the largest heat islands in the city. The Austrian Social Democratic Party (SPÖ) wanted to build a market hall on this site, while the Greens wanted a park. An open competition was to be held in the fall of 2021, but currently only suggestions for use are still being sought from Viennese citizens.

In the run-up to the competition, there were numerous discussions about the visualizations that the SPÖ and the Greens had brought to the city. The architect Katharina Puxbaum was responsible for the Greens’ visualizations. “The Greens approached me in spring 2020. They had visions for the area, but were looking for professional expertise to present these initial ideas in such a way that they could be implemented,” she says in conversation. The visualizations could be seen everywhere in Vienna in 2021: in the daily newspapers, on posters outside and on social media. While the SPÖ won the Vienna elections in 2020 and included the market hall in its government program, the Greens tried to gather supporters for their idea and petition. Around 20,000 people are said to have signed it in the meantime.

SPÖ: “No realistic or even realizable designs.”

The SPÖ and the business group “Innovation, Urban Planning and Mobility”, which was led after the election, took a different approach to this project. They did not include any planners in the visual representations. In response to inquiries, they let us know: “The ‘renderings’ were created internally and were only intended to initiate a discussion about the redesign of the Naschmarkt parking lot. No architect was involved, as these were not realistic or even realizable designs.” This desired discourse was also initiated via the platform markthalle.wienwirdwow.at as a public participation process for the redesign of the Naschmarkt parking lot. “Due to the enormous interest”, as it says on the platform, the participation process was even extended over the summer in order to collect suggestions, wishes and ideas for the redesign of the Naschmarkt. This participation is still ongoing.

Presentation or propaganda

“Are visualizations a means of propaganda?” asked the Bernese daily newspaper “Der Bund” in an article worth reading entitled “The fantastic images that anticipate the future” at the beginning of 2021. In Vienna, some people would currently answer this question with a “yes” with regard to the plans for the Naschmarkt. But is it really that bad? After all, the City of Vienna’s floating gardens by Carla Lo Landschaftsarchitektur, which are now not only well received but extremely popular, are no different.

Before the municipal elections in 2015, the office was asked for a visualization: “Inspired by the floating gardens in Paris, we were asked to green the Kaiserbadschleuse on the Danube Canal. We found the idea interesting, the visualization was fun, but we couldn’t say whether it would actually be implemented,” says Lo in the interview, and indeed, the visualizations were heavily promoted during the election campaign. After the elections, however, the project went quiet. Some obstructive circumstances had to be clarified first. When the 2020 election campaign began, everything happened very quickly. Just three months after the start of construction, the floating gardens were a prestige project. The opening was staged with extra-large trees delivered for journalists.

In direct comparison

It is to be hoped that the redesign of Praterstrasse in Vienna’s second district by 3:0 Landschaftsarchitektur will not have to wait quite so long. One less lane, more space for cyclists and pedestrians and 80 newly planted trees will turn this connecting road into a green boulevard. The project was presented during the 2020 municipal election campaign with visualizations contrasting the current (traffic) situation. However, the fact that Praterstrasse became an election campaign project is more of a coincidence. The competition had already been won by 3:0 a year and a half ago. Corona delayed the project, so it was only presented in the fall of 2020. Nevertheless, these examples illustrate how landscape architecture visualizations are repeatedly used to gain votes for the respective parties. This is particularly noticeable when politicians are praised in the media for their projects, but the landscape architects can only be found in the credits of the renderings.

The impact of renderings

“The green ring on the plan simply has no meaning – even for people who can read plans. A closed cubature can also be captured in the floor plan, but a tree – in all its different forms and with all its qualities – is very difficult for many people,” says Daniel Zimmermann. He co-founded Büro 3:0 over 20 years ago and in this position has followed the development of presentation methods over the years.

For him, the advantages of visualizations are obvious: “Especially in participative processes, strong renderings can achieve a lot. After all, we want to communicate with people who can hardly read plans, if at all. We have also found that we can illustrate the temporal perspectives particularly well. Landscape architecture projects don’t simply end with a ‘handover of keys’. We can show everyone involved what our project will look like in five, ten or fifty years’ time.” This is an important aspect, especially when you consider that visualizations are always perfect, even confusingly similar to reality. The disappointment that the project does not yet look as presented when it opens can be avoided in this way.

Visualizations as “green washing”

“But visualizations are no longer just a presentation tool. We already develop mainly in 3D. For us, it provides quick creative feedback and we see the benefits in interdisciplinary projects. The step into the third dimension is particularly important in the street space, when you work hand in hand with existing buildings, traffic planners and climatologists. This allows us to see very quickly and clearly for everyone whether the various measures have a holistic effect.” Zimmermann also believes that you are never immune to becoming a PR pawn in an election campaign, especially when planning in public spaces.

However, he sees a bigger problem elsewhere: “I can no longer look at luxury real estate magazines. The ‘green washing’ that goes on in this scene via visualizations borders on fraud. Of course, as a landscape architect, I see these pictures and know that this façade cannot be planted in this form. That the plants won’t grow or that the tree can’t even stand there because of the underground parking garage. As a layman, all you can see is the beautiful green future living space that will never exist.”

Naschmarkt Vienna: back to the future

Of course, the visualizations of the park at Naschmarkt could also be used for “green washing”. This cannot be ascertained at the present time. What is certain, however, is that the visualizations are not only green and atmospherically beautiful, but also technically sound and with high design standards. “The concept, the pathways and the water features are intended to make people aware that they are standing right above the Wien River. The current parking lot is nothing more than a lid on this highly regulated river. However, the planting mounds would allow us to plant smaller trees and shrubs, creating a public park for all age groups, with opportunities to spend time without the pressure to consume.”

The professional approach to visualizations seems to be paying off. For example, a video by an opposition party claiming that this cover could not be greened has already disappeared from the internet. But even if the Greens are successful with their petition, the design will probably not be implemented in this form. A tendered competition is mandatory for a public project. It therefore remains to be seen what will happen at this site.

Possible labeling of visualizations

It is also unclear how visualizations themselves and their use in landscape architecture will develop in the future. The suggestion that visualizations – similar to advertisements – could be labeled as mandatory makes sense to all of the interviewees. In this case, the credits would be liable for the quality. In the meantime, city dwellers and media consumers will have to get used to the fact that visualizations can be both concrete proposals and populist “fake news”. But they are primarily one thing: valuable opportunities to present landscape architecture, sometimes even anticipating a green future.

Blockchain technology is often associated with cryptocurrencies such as Bitcoin, but has many more applications, particularly in the area of mobility. Blockchain is a decentralized database that records transactions transparently and tamper-proof. In mobility, this technology opens up new opportunities to optimize transport networks, prevent fraud and increase efficiency. Blockchain provides a secure platform for managing the data and transactions that occur daily in complex transportation systems.

Fun fact: According to a study by Deloitte, blockchain technologies in the transport sector could generate global savings of up to 30 billion US dollars by 2030.

Blockchain is based on several principles that make it particularly suitable for use in mobility.

Decentralization

Instead of a central database, information is stored in a network of nodes. This decentralization makes the system resistant to failures and manipulation.

Transparency

Every transaction is recorded in the blockchain and can be viewed by all network participants. This promotes trust and prevents fraud.

Security

Cryptographic encryption and consensus mechanisms make the blockchain virtually tamper-proof. This is particularly important for sensitive data such as ticketing information or payment details.

Smart contracts

Smart contracts are self-executing contracts that are executed automatically when certain conditions are met. They automate processes such as payments, bookings or insurance claims.

Practical example: A blockchain-based car sharing system could use smart contracts to only grant access to vehicles once payment has been confirmed.

Blockchain offers a wide range of applications that can make mobility safer, more efficient and more transparent.

Digital ticketing and payment processing

Blockchain enables a tamper-proof and transparent ticketing system for public transportation. Users can purchase their tickets digitally without having to rely on central providers.

Car sharing and ridesharing

Decentralized platforms could make carsharing and ridesharing services more efficient by enabling the booking, payment and handling of journeys directly between users.

Logistics and supply chains

In logistics, blockchain can be used to track the transportation of goods and prevent manipulation in the supply chain. Every movement of a delivery is recorded in the blockchain, which increases transparency.

Traffic management and parking systems

Blockchain can make traffic management systems more efficient by providing real-time data on traffic flows and parking options. Users could reserve and pay for parking spaces via decentralized platforms.

Practical example: a pilot project in Vienna is using blockchain to securely manage parking tickets and make the process more transparent.

The introduction of blockchain in mobility offers numerous advantages that benefit both users and operators.

Transparency and trust

Blockchain increases transparency by making all transactions publicly visible. This creates trust between users and providers and reduces fraudulent activities.

Fraud protection and security

Cryptographic encryption makes the blockchain secure against manipulation. This protects users from fraud and operators from financial losses.

Increased efficiency

Blockchain automates processes such as payments and bookings, saving time and costs. Smart contracts make it possible to minimize administrative tasks and speed up processes.

Data integrity

Data stored in the blockchain cannot be subsequently changed. This ensures that all information remains correct and trustworthy.

Expert opinion: According to a study by PwC, blockchain-based systems could reduce operating costs in the transportation sector by up to 15 %.

Despite its advantages, there are also challenges that need to be overcome when introducing blockchain in mobility.

Scalability

Blockchain technology reaches its limits with high transaction volumes. Cities with busy transportation systems need to ensure that the technology can be scaled.

Energy consumption

Blockchain systems, especially those with proof-of-work consensus mechanisms, consume significant amounts of energy. This is at odds with the sustainability goals of many cities.

Legal and regulatory issues

The introduction of blockchain in mobility requires a clear legal framework, particularly with regard to data protection, liability and contract law.

Acceptance by users and operators

The implementation of new technologies requires time and acceptance from users and operators. Transparent communication about the benefits and functionality of blockchain is crucial.

Expert opinion: According to a survey by Gartner, 40% of companies consider regulatory uncertainty to be the biggest obstacle to the introduction of blockchain.

Vienna: Blockchain for parking systems

In Vienna, blockchain is being used to digitize parking management. Users can reserve and pay for parking spaces and extend their parking times, all via a decentralized platform.

Seoul: blockchain for local public transport

In Seoul, the city is testing a blockchain-based platform for public transportation that makes ticketing and payment processing more secure and transparent.

Rotterdam: logistics with blockchain

Rotterdam is using blockchain to make logistics chains in the port more efficient. Every movement of containers is recorded in the blockchain, which increases transparency and prevents fraud.

The further development of blockchain technology will continue to revolutionize mobility in cities.

  1. Integration with IoT: IoT devices could be connected directly to the blockchain to capture and analyze traffic flows and vehicle data in real time.
  2. AI-powered analytics: AI could use blockchain data to analyze traffic flows and create predictive models for more efficient mobility
  3. Smart contracts for insurance: Insurance claims could be automated and processed faster by relying on blockchain-based smart contracts.
  4. Decentralized mobility platforms: Blockchain could serve as the basis for platforms that connect users* directly with providers* and eliminate the need for centralized intermediaries.

Future outlook: In Dubai, a blockchain system is being developed that integrates traffic management, insurance and ticketing into a single platform to make the city’s mobility more efficient and transparent.

Blockchain technology offers enormous opportunities to make mobility in cities safer, more efficient and more transparent. From digital ticketing and car sharing to logistics and traffic management – blockchain creates trust and optimizes urban processes. Despite the challenges, particularly in terms of scalability and legal issues, blockchain has the potential to fundamentally transform mobility and make cities smarter and more sustainable.

Concluding thought: Blockchain is more than just a technical trend – it is a transformative force that will shape the mobility of tomorrow. A future in which transportation systems are transparent, efficient and connected starts with blockchain technology.

COP27 – result and breakthrough

After an extension, the COP27 global climate conference in Sharm El-Sheikh ended in the early hours of November 20. There was one major breakthrough, but overall the outcome is rather disappointing. Read everything you need to know about the COP here.

The Sharm El-Sheikh climate agreement

It is now common for climate conferences to end in overtime. The often tough, complex negotiations took a little longer than planned this year too. In the morning hours of November 20, 2022, the time had come and the expected climate agreement was adopted by almost 200 countries.

The COP27 breakthrough

Expectations for COP27 were not too high, although the consequences of climate change, inflation and the war in Ukraine meant that the stakes were particularly high in 2022. Despite many doubts, a breakthrough was achieved: support for victims of climate change was officially agreed. These financial benefits, which are intended to remedy climate damage, are known as “loss and damage”. The best example of the need for such financial resources is the devastating floods in Pakistan. Climate justice is required here: those who are most responsible for the drastic consequences of climate change are obliged to make compensation payments to the countries that often emit little and are severely affected.

After a long struggle and a lot of pressure from the G77 group, which includes over 130 poorer countries, an agreement was reached. The EU played a leading role in this. However, it demanded that the financial burden of the climate damage fund should not fall solely on richer countries. Details on who pays how much are to be decided by COP28 in 2023.

By the way: You can find our article on expectations for COP27 here.

Fossil fuels

Last year’s COP26 in Glasgow focused on fossil fuels and coal in particular. For the first time, the reduction of dependence on coal was included in an international climate agreement. This year, there was a draft that called for all types of fossil fuels to be phased out. However, this was rejected.

And that’s not all: representatives of major oil and gas companies were present in large numbers at COP27. The exhibition area was partly dominated by companies whose goals were in stark contrast to the content of the COP27 negotiations. The Egyptian hosts even negotiated new gas contracts during the conference.

As a result, although the final document emphasizes that renewable energy should be promoted, it also contains references to “low-emission energy”. This refers, for example, to gas, which as a fossil fuel produces fewer emissions than coal. The vague term also provides loopholes for the use of other fossil fuels, whose emissions can be offset by mechanisms for carbon capture and storage.

1.5 degrees at the COP27

The famous goal of the Paris Climate Agreement from 2015 to limit global warming to 1.5 degrees can also be found in the COP27 final declaration from Sharm El-Sheikh. The text repeats the statements from the Glasgow Pact of 2021 to limit global warming. However, the agreement does not go any deeper than “The 1.5C target requires rapid, deep and sustained reductions in global greenhouse gas emissions reducing global net greenhouse gas emissions by 43% by 2030 relative to the 2019 level”.

Last year in Glasgow, it was decided to take a much more ambitious approach to climate protection measures in a mitigation program. Here, too, many rich countries resisted making commitments. They insisted on making climate protection measures optional and in line with national circumstances. Further discussions are to be held annually until 2026.

Financing

The Prime Minister of Barbados, Mia Mottley, gave an impressive speech in Sharm El-Sheikh. In it, she spoke of the loss of human life, livelihoods and dignity. Among other things, she proposed the “Bridgetown Agenda” to finally make progress in financing green, resilient investments. This agenda proposes reforming the international financing system. According to estimates by the International Energy Agency, 4 trillion US dollars will be needed every year until 2030. This is the only way to invest enough in renewable energies by 2030 to reach net zero by 2050.

International development banks such as the World Bank are called upon here to increase climate financing and make it more easily accessible. This was also recommended at the G20 summit taking place at the same time, at which Germany and the USA, among others, advocated a reform of the World Bank. However, the proposal was not included in the COP27 final declaration. It is to be discussed further at IMF and World Bank meetings in the spring.

Before the COP is after the COP

The next COP will take place in Dubai in the United Arab Emirates at the end of 2023. Countries should submit their adjusted Nationally Determined Contributions (NDCs) by then at the latest. The EU has also promised to develop details of the planned financial shield for climate damage by then and to publish a precise figure for the funds available. Under the leadership of a country whose economy is 30 percent oil-based, no official move away from fossil fuels is to be expected at the COP in 2023 either.

The disappointment surrounding COP27 is great. At the same time, however, there is a growing awareness that climate policy is also happening on many other stages. Civil society keeps a closer eye on the climate conference every year and is now demanding that governments keep their promises.

Despite all the negative news, there is still a glimmer of hope: 10 years ago, the world was still on course for global warming of 6 degrees. About five years ago it was 3 degrees. At present, we can expect 2.4 to 1.8 degrees of warming. This is still significantly more than 1.5 degrees, but the review also shows what is possible. Now we need to demonstrate with action what the implementation of climate conferences looks like.
