Cities on the road to climate neutrality

Climate-neutral by 2035. The goals that once sounded ambitious now seem like urgent necessities in view of global heat records and insufficient progress. But the road to climate neutrality remains rocky and complex. Our first issue of the year is therefore dedicated to the key questions: How can cities achieve this change? Which technologies and strategies will actually lead to the necessary savings? And fundamentally – is the goal of climate neutrality in itself sufficient or do we need more ambitious visions?

Climate neutrality – also a question of willpower

In this issue, we talk to experts and take a look at cities such as Feldheim and Wuppertal as well as institutions such as the University of Göttingen, which have already achieved impressive results. Their knowledge provides valuable insights into how climate neutrality can be achieved and, above all, maintained. From innovative energy systems and circular building approaches to new forms of green infrastructure that make urban spaces not only more climate-friendly but also more liveable – it is clear that the means for change exist if the will is there. The city of Hamburg proves that this will exists in some places: in a referendum, the people of Hamburg voted to bring forward the goal of climate neutrality from 2045 to 2040 and to stipulate binding annual CO₂ ceilings as well as transparency and social compatibility in the Climate Protection Act.

At the same time, however, political developments such as the debate about a possible overturning of the “combustion engine ban” make it clear that technical progress alone is not enough – social and political setbacks can quickly cost years gained in climate protection.

Willingness of society

And what about society’s willingness to support such radical changes? What about our will? What is required of us all to make the change a success? Climate neutrality goes far beyond technical issues; it also makes fundamental demands on our behavior, our priorities and our willingness to leave our comfort zones. The backward-looking debate surrounding the combustion engine shows how fragile the acceptance of comprehensive measures can be. This issue therefore takes a critical look at whether and how German cities can actually achieve this goal in the coming years – and what role urban planners, landscape architects and civil society have to play in this.

Change out of conviction

2026 could be the year in which we take the decisive step towards climate neutrality – or finally realize that ambitious promises alone are not enough. May the next few years show that change is possible if we shape it not only out of insight, but also out of conviction.

Cities today face major challenges when it comes to mobility. Private transport leads to traffic jams, air pollution and land consumption. Shared mobility offers a solution that relies on the shared use of vehicles and thus relieves both the environment and the roads. Digital platforms and apps allow people to use vehicles flexibly without having to own a car. These new mobility models are not only an environmentally friendly alternative, but also an important step towards a more sustainable and liveable city.

Fun fact: According to a study by McKinsey, shared mobility solutions could reduce the need for private cars in cities by up to 30% by 2030.

Shared mobility is based on a combination of several technologies that work together seamlessly to provide users with a simple and convenient experience.

Digital platforms

Digital platforms such as Uber, Lyft, Free Now and Share Now connect users and vehicles in real time. These platforms offer features such as booking, payment and route optimization that allow users to use a vehicle immediately and without much effort.

Internet of Things (IoT)

The IoT is an integral part of shared mobility. Vehicles are often equipped with GPS and sensors that report their location and status in real time. This data helps to optimize operations by providing information on availability, maintenance and routes.

Mobile apps

Mobile apps are the main tool through which users access shared mobility services. They enable the booking of rides, payment and provide access to information such as the location of the next available vehicle and estimated arrival times.

Practical example: In Amsterdam, the car-sharing company Share Now uses a platform that provides real-time information on available vehicles and allows users to unlock the cars via an app.

Shared mobility comprises various models that are tailored to the different needs of users.

Car sharing

Car sharing enables users to rent a car for short periods of time. Models such as station-based car sharing (e.g. Zipcar) and free-floating car sharing (e.g. Share Now) offer flexibility and reduce the need for private car ownership.

Bike sharing

Bike sharing systems offer an environmentally friendly alternative for short distances. Users can find and use bikes at special stations or via GPS using an app. This promotes healthy, emission-free mobility.

Ridesharing and ride-hailing

Ridesharing (e.g. BlaBlaCar) and ride-hailing (e.g. Uber) offer users the opportunity to share journeys or order a vehicle with a driver. This optimizes traffic flow and reduces environmental pollution.

Scooter sharing

Electric scooters, which can be rented via an app, have established themselves as a popular option for short journeys. They are space-saving and emission-free and complement other means of transportation in the urban environment.

Practical example: Lime offers scooter sharing in many cities around the world and is a practical solution for the so-called “last mile”, which is often difficult to cover with public transport.

Shared mobility offers numerous advantages that have a positive impact on cities, the environment and users.

Reduction of emissions

As fewer people own their own car, the number of vehicles on the roads is reduced. Shared mobility promotes the use of electric and low-emission vehicles and thus helps to reduce CO₂ emissions.

Less traffic and congestion

When people share vehicles, traffic is reduced. Fewer vehicles on the roads means less congestion, better air quality and an overall more pleasant urban environment.

Lower costs for users

Shared mobility is often cheaper than owning a car, as users only pay for what they actually use. Maintenance, insurance and other fixed costs are eliminated.

Flexible mobility

Shared mobility models offer users a flexible and convenient way to get around without having to worry about finding a parking space or vehicle maintenance.

Expert opinion: According to a study by Deloitte, 55% of millennials prefer shared mobility solutions to owning their own car as they offer flexibility and cost efficiency.

Despite its advantages, shared mobility faces various challenges that need to be overcome.

Infrastructure and space requirements

Shared mobility requires special parking spaces and parking areas for bicycles and scooters, which can lead to conflicts in public spaces. Cities need to provide space for these vehicles without interfering with pedestrian traffic.

Safety concerns

Scooters and bikes can pose a safety risk, especially in busy areas. Accidents and lack of helmet use are common problems that jeopardize the safety of users.

Legal and regulatory issues

The regulation of shared mobility services is complex and varies from city to city. Providers must adhere to local regulations, which can increase operating costs and limit availability.

User acceptance and habits

Although shared mobility offers many advantages, some people still prefer to own their own car. It takes time and education to increase the acceptance of shared mobility solutions.

Example: In San Francisco, the rapid growth of scooter sharing has led to problems with poorly parked scooters on sidewalks, resulting in complaints from citizens and the need for stricter regulations.

Amsterdam: Car sharing integration with public transport

In Amsterdam, car sharing providers work closely with public transport to offer integrated mobility solutions. Users can use car-sharing vehicles as a supplement to public transport and thus increase flexibility.

San Francisco: Scooter sharing

San Francisco has successfully integrated scooter sharing and introduced strict regulations to ensure that the vehicles are parked properly and the safety of users is guaranteed.

Copenhagen: Bikesharing

Copenhagen, known as a bike-friendly city, has developed a comprehensive bike-sharing program that is used by locals and tourists alike. This has reduced the use of cars in the city center.

The future of shared mobility will be shaped by the integration of new technologies and business models.

  1. Autonomous driving: Autonomous vehicles could make shared mobility even more efficient and safer as they are continuously available and can move autonomously.
  2. Artificial intelligence (AI): AI can help to better manage traffic flows and vehicle availability in order to maximize efficiency and adapt the service to the needs of users.
  3. Mobility as a Service (MaaS): MaaS platforms combine different modes of transportation in a single app that integrates all mobility services from public transport to car sharing and offers a seamless user experience.
  4. Sustainability and electric drives: The introduction of electric shared mobility vehicles will help reduce emissions and improve air quality in cities.

Future outlook: A pilot project in Helsinki is testing autonomous, electric car sharing vehicles that can be booked via a MaaS app and offer users a complete, sustainable mobility solution.

Shared mobility is fundamentally changing the way people travel in cities. Through the use of digital platforms and innovative business models, it offers a sustainable alternative to private car ownership and contributes to solving urban challenges. Despite the challenges, particularly in terms of infrastructure and user acceptance, it is clear that shared mobility has the potential to make urban mobility more efficient, environmentally friendly and flexible.

Concluding thought: Shared mobility is more than just a technology – it is a vision for sustainable mobility that conserves resources and creates quality of life. If cities and providers work together, shared mobility could become an essential part of urban life in the future.

If you take a closer look at the national arena in the Romanian capital Bucharest, you are instinctively reminded of a Bundesliga stadium. This is no coincidence, as the roots of the arena lie in Germany.

The Romanian national arena in Bucharest has German genes: the 55,000-seat soccer stadium was designed by Hamburg architects Gerkan, Marg & Partner (gmp), the structural design was carried out by the engineering firms Schlaich Bergermann & Partner from Stuttgart and Krebs und Kiefer from Karlsruhe, and the general contractor was the construction company Max Bögl from Sengenthal in the Upper Palatinate.

Although it is a soccer stadium, the building is named after a female discus thrower: Lia Manoliu won the gold medal at the 1968 Olympic Games in Mexico City. However, the stadium is now known exclusively as the “Arena Națională”, i.e. the “National Arena”. The new building was named after Lia Manoliu after its predecessor, the “Stadionul Național Lia Manoliu”, the old national stadium. It previously stood on the same site and was demolished in 2008.

Unlike the arena, it was a multi-purpose stadium. Its stands were not covered and the athletics facilities were located between the pitch and the stands. This meant that at the beginning of the millennium it no longer met the requirements for a venue for international soccer matches. In 2006, Max Bögl won the tender for the construction of the new national arena – which, however, had been planned quite differently at the time. However, the German company submitted an alternative project to the client, the city of Bucharest, which was much simpler and cheaper to build.

The National Arena bears unmistakable similarities to Frankfurt’s Waldstadion. This is no coincidence: the same team of general contractors, architects and engineers built the stadium on the Main between 2002 and 2005. The closable membrane roof in particular is almost a one-to-one replica of the construction in Frankfurt. As there, the roof is located in the large video cube above the pitch when folded up. It extends within 15 minutes when required. It then spans the area between the grandstand roofs. The stand roofs themselves are supported by a so-called pressure ring, which towers over the stadium like a crown. The ring rests on 40 steel pillars, which sit on the concrete construction of the grandstand ring.

The stands have two tiers. The architects designed the spectator area with seating shells in different shades of red, blue and yellow, the national colors of Romania. On the outside of the stadium, the verticality of the concrete columns supporting the stands defines the appearance of the building. The grassy embankment on which the arena stands is still a relic of the old national stadium. It mediates between the new building and the historic sports park that surrounds it. Large steps lead up the rampart. They make a visit to the National Arena a bit of a pilgrimage.
