Modern trends in sustainable transport: challenges and opportunities

December 17, 2024
Although cities occupy only 3% of the Earth's land, they are home to about 3.5 billion people, or half of the world's population, which leads to them accouting for 95% of the carbon dioxide emissions from the transport sector. As the number of city residents continues to grow, so do air pollution levels, traffic congestion, and, subsequently, more wasted money and time, harm to public health, and damage to the environment. Experts unanimously agree: these problems can be addressed by developing sustainable transport.

Sustainable transport, which is celebrated globally on November 26, is a mode of movement or its organization that has a smaller environmental impact, reduces traffic jams, and contributes to improving quality of life as well as public health.

Sustainable mobility includes walking, cycling, scooter riding, public transport, as well as eco-friendly cars, transit-oriented traffic reduction, the use of shared transport, and the development of efficient and environmentally friendly urban transport systems, which not only save city space but also encourage a healthier lifestyle.

According to Professor Dr. Olegas Prentkovskis, Dean of the Faculty of Transport Engineering at VILNIUS TECH, in the long term, sustainable transport is extremely valuable. For example, traditional transport emits about 25% of all greenhouse gases, whereas sustainable transport emits almost none or significantly less.

"Moreover, it is economically promising, helps create new jobs, positively contributes to sustainable national and international development, and social justice—for example, public transport and non-motorized vehicles become accessible to everyone, regardless of economic, social, or physical differences," shares the Dean of the Faculty of Transport Engineering at VILNIUS TECH.

Changing travel habits is necessary

One of the best examples of sustainable transport is public transport, which is one of the most sustainable, eco-friendly, and efficient modes of transportation. According to Darius Snieska, Regional Manager of UAB “SCANIA Lithuania,” the more people use such services, the more benefit the entire transport infrastructure gains.

Loreta Levulyte-Staskeviciene, head of JUDU, agrees and states that public transport allows cities to be built where air quality improves, noise is reduced, and mobility becomes more convenient, all of which contribute to the higher quality of life. However, to ensure better urban mobility, it is essential to change travel habits.

"This is a huge challenge, for which more buses and trolleybuses are not enough. An effective transport system is created holistically—integrating different transport modes, routes, city planning, and social as well as environmental factors," explains JUDU Director Loreta Levulyte-Staskeviciene. "By 2030, we aim to balance mobility in the capital so that more than 70% of trips within the city will be sustainable—without a car, which means that residents and visitors will choose public transport, micro-mobility, and walking as an alternative."

Public awareness is crucial

According to Darius Snieska, the transport sector is also facing the task of adapting to new market conditions, customer needs, and technologies—alternative fuels are emerging, car-sharing companies are competing with private clients, longer distances are often covered by airplanes, and alternative transport modes are becoming more popular.

Moreover, transport must meet many sustainability requirements—it should be comfortable for the client, quiet, maneuverable, made from recycled materials, easy to maintain and repair, and cause as little environmental pollution as possible, especially in places where people gather.
While vehicles are becoming more efficient and environmentally friendly, new technologies come with additional costs that must be covered by the end consumer.

"Often, the initial investment in new transport technologies is higher, but over their lifetime, they become a much more efficient and financially advantageous alternative to current technologies. It's hard for clients to accept this, as they usually only see the upfront investment, so it's important to educate the market. We must also remember that automation and AI technologies will offer possibilities that current transport cannot. Currently, flexible vehicle service and repair prevention algorithms help cars run longer without unscheduled repairs, which means maintenance cost reduction," says Darius Snieska, Regional Manager of UAB “SCANIA Lithuania.”

It is clear that in order to achieve sustainable changes, it is very important to increase public awareness, change their attitudes, and habits.

"The emergence of alternative energy sources is a very welcome phenomenon, however, even the most eco-friendly car can still cause traffic jams, which swallow a lot of time, and that time comes at a price. The key is not just ecology—transport must be used appropriately," emphasizes Darius Snieska.

From biological bridges to living facades: how civil engineers are reshaping cities
Modern buildings are no longer made of concrete and steel alone. Biology, artificial intelligence, and sustainable technologies are becoming an integral part of construction, transforming the way cities are designed and built. As technology advances and environmental awareness grows, civil engineers are developing innovative materials and construction methods that are more sustainable, durable, and environmentally responsible. One of these innovators is Assoc. Prof. Dr. Ronaldas Jakubovskis, a researcher at the Faculty of Civil Engineering at VILNIUS TECH, whose work is helping shape the future of urban environments. Turning Research into Real-World Structures Assoc. Prof. Dr. Ronaldas Jakubovskis serves as a Senior Researcher at the Laboratory of Innovative Building Structures, where his work focuses on developing advanced structural solutions through experimental testing, laboratory research, and numerical modelling. However, innovation rarely begins with a completely new idea. According to Dr. Jakubovskis, much of the research process is dedicated to analysing existing materials and construction technologies to understand how they can be improved. [caption id="attachment_88679" align="alignnone" width="2560"] Ronaldas Jakubovskis[/caption] „The most rewarding moment is when years of laboratory research become a real structure that can be built and experienced in a natural environment,“ he says. Although he works in academia, Dr. Jakubovskis sees himself primarily as a civil engineer supporting other civil engineers. While structural designers and project managers oversee the overall design of buildings and infrastructure – determining layouts, dimensions, and cost-effective construction solutions – researchers provide the specialised expertise needed to develop new materials and solve complex engineering challenges. „Practising engineers often don't have enough time to investigate highly specialised solutions or explore entirely new materials – that's where we come in. Sometimes we analyse complex structural behaviour through numerical modelling, and sometimes we investigate how emerging materials can be applied in construction. In my opinion, research engineers don't quite fit the traditional stereotype of scientists wearing white lab coats or solving abstract equations all day. Our work is highly practical—we often design, manufacture, and physically test new structural systems ourselves.“ Engineering That Leaves a Visible Legacy Among the projects he is most proud of is the Biological Bridge installed at the Kairėnai Botanical Garden, as well as the Living Concrete wall currently being developed for the rooftop of the Lithuanian National Drama Theatre. Both projects demonstrate how engineering can merge sustainability, science, and architectural design. „These projects represent the culmination of years of laboratory work and numerical modelling. They are demonstration structures that show what is possible when innovative materials meet advanced engineering. I also value their aesthetic qualities. Designing complex organic forms allows you to feel a little like a sculptor creating a work of art.“ Looking ahead, Dr. Jakubovskis believes his greatest achievements are still to come. His long-term vision is to create buildings with façades intentionally designed to be colonised by living organisms, allowing them to interact naturally with their environment while providing ecological and functional benefits. [caption id="attachment_88005" align="alignnone" width="2560"] Ronaldas Jakubovskis[/caption] „We are currently developing larger demonstration projects, seeking research funding, and expanding international collaborations. I believe that within the next five years, we'll be able to stand in front of one of these buildings and say: this is a significant achievement.“ A Profession That Will Still Matter in 100 Years For Dr. Jakubovskis, choosing civil engineering was an easy decision. Since childhood, he enjoyed watching buildings rise from the ground and observing construction sites and heavy machinery. „You don't need extraordinary dreams to become a civil engineer. If you want to build, you become an engineer. It's not like travelling to space or conducting research in Antarctica.“ What motivates him most is the opportunity to create structures that remain valuable for decades – or even centuries. „Every civil engineer feels proud when driving past a bridge or building they helped design, and they will always point it out to everyone in the car,“ he says with a smile. His own career began in structural design after completing his third year of university. He later pursued doctoral studies focusing on the cracking behaviour and deformation of reinforced concrete structures before returning to industry. Eventually, an invitation to rejoin VILNIUS TECH brought him back to academia. „I came back, and today I'm doing exactly what I truly enjoy.“ Advice for Future Engineers As both a researcher and lecturer at the Faculty of Civil Engineering, Dr. Jakubovskis emphasises that a university education is essential for anyone pursuing a career in civil engineering. „It would be extremely difficult to master this profession through self-study alone. Should you begin with theoretical mechanics, mechanics of materials, or structural mechanics? University programmes are carefully designed so that knowledge develops step by step, preparing graduates to become highly qualified professionals.“ He also offers practical advice to prospective students: „Don't be afraid of mechanics, physics, or mathematics. Every semester, identify a few key subjects, understand them thoroughly, and make sure you truly master them. Once those foundations are in place, everything else builds naturally.“ Industry Investing in Future Engineers Preparing the next generation of civil engineers is a shared responsibility between universities and industry. As digitalisation, artificial intelligence, and emerging technologies continue to reshape construction, employers increasingly recognise the importance of investing in future talent. The Faculty of Civil Engineering at VILNIUS TECH enjoys long-standing partnerships with the Lithuanian Builders Association (LSA) and the Lithuanian Association of Civil Engineers (LSIS), both of which actively support education and professional development. The Faculty's industry partners – including Hanner, Gilesta, and Alvora – offer scholarships to first-year Civil Engineering students, helping talented young people begin their studies. Other partners, such as Naresta, PST Group, HSC Baltic, and numerous construction companies, contribute by delivering guest lectures, presenting real-life projects, and inviting students to construction sites, where they gain first-hand experience of modern engineering practice. These close collaborations ensure that VILNIUS TECH programmes remain aligned with industry needs while providing students with practical knowledge, professional skills, and valuable connections long before graduation.
