Questions related to Sustainable Transport
As part of the green transformation of maritime transport, should maritime sailing transport be restored due to the high carbon intensity of large transport ships?
100 large internal combustion transport ships emit as much CO2 as a million internal combustion cars. Transport ships are already being built that are equipped with alternative, lower- or zero-emission energy sources and modern sails, in addition to high-emission internal combustion power. Unfortunately, power supply based solely or mainly on such emission-free energy sources such as solar energy based on installed photovoltaic panels is currently used only on small ships, catamarans, boats, etc. On large transport ships, both passenger and cargo ships, this type of power supply can be a supplementary power supply to provide the ship with electricity used in some of the on-board equipment. Besides, technologies are being developed to power transport ships with low-carbon biofuels, nuclear or hydrogen power. However, regardless of the type of power supply used to generate electricity and/or energy to power the engines that drive the ship's turbines, it is almost always also possible to use modern sailing structures, which will be an additional source of energy based on the most traditional source of energy that enables the movement of sea vessels, which is wind energy. In addition, modern sails can also be covered with photovoltaic panels, so they can also significantly increase the area on which the said panels are installed and thus will also be a source of electricity.
In view of the above, I address the following question to the esteemed community of scientists and researchers:
As part of the green transformation of maritime transport, should maritime sailing transport be restored in view of the high carbon intensity of large transport ships?
Should maritime sailing transport be restored due to the high carbon intensity of large transport ships?

Is 12 years to switch the entire automotive sector to electromobility a long or short time, considering both the currently available green technologies and eco-innovations in electromobility, hydrogen-powered vehicles, zero-emission production of hydrogen and other e-fuels, development of zero-emission energy sources, high recycling rates of electric vehicles, etc.?
Is it possible to shift the whole of motorisation in Europe to electromobility by 2035, i.e. to implement the European Union's plan under which, after 2035, no new combustion-engine cars will be registered and put into service, and only zero-emission vehicles, i.e. electric and hydrogen vehicles, will be registered?
By 2035, will there be a significant drop in the price and increase in the uptake of e-fuels, i.e. synthetic fuels produced from water or hydrogen extracted from the air in a production process powered by renewable and emission-free energy sources?
The green transformation of the automotive industry is one of the key components of the green transformation of the economy, with the aim of building a sustainable, zero-emission, green closed loop economy as quickly and efficiently as possible. A key objective of the green economy transition is to slow down and possibly halt accelerating global warming and reduce the scale of the global climate catastrophe, which, according to long-term climate change models, could already occur by the end of this 21st century. The green transformation of motoring is primarily about the development of electromobility and hydrogen-powered vehicles through the application of available green technologies and eco-innovations in the development of electromobility, hydrogen-powered vehicles, zero-emission production of hydrogen and other e-fuels, the development of zero-emission energy sources, a high level of recycling of electric vehicles, and the activation of this process through the increase of government subsidy programmes within the framework of green finance, the introduction of tax credits to mobilise business for green investment projects, the introduction of new pro-climate and pro-environmental regulations, etc. In order to activate pro-environmental business processes and to activate operators to join the green transformation of the economy, specific calendars for the said green transformation processes of the economy are enacted, including the pro-climate and pro-environmental transformation of the car, rail, river, sea and air transport sectors. In many countries of the world, the rail transport sector is already 100 per cent or mostly converted to electromobility. Other segments of transport are mostly dominated by vehicles, ships, aircraft powered by internal combustion engines that burn high-emission fossil fuels. So there is still a lot of work to be done on the green transformation of the various transport sectors. In March 2023, the European Union Parliament adopted a plan to restrict the purchase of internal combustion cars after 2035 as an important motivating factor for the development of electromobility, i.e. the development of emission-free motoring. An evaluation of the development of electromobility in the European Union and an assessment of the feasibility of this plan is to be carried out in three years' time. The following exception was added to earlier drafts of this regulation: synthetic fuels produced from, for example, water or hydrogen extracted from the air on the basis of zero-emission production of these fuels, i.e. by using electricity generated from renewable and zero-emission energy sources in the hydrogen production process. Such solutions for the production of e-fuels and their use in powering motor vehicles will be permitted in the European Union after 2035. In the government-controlled meanstream media in the country where I operate, there has been the usual misinformation about the European Union's climate policy. Under the current plan, it will not be possible to register a car with an internal combustion engine powered by petroleum refining derivatives. Well, the possibility of buying and registering cars with combustion engines will not necessarily be prevented after 2035, because it will not be economically viable to buy a new car with such an engine after the restrictions have been introduced. According to current forecasts of electromobility development, it will not be economical to buy an internal combustion car after 2035, because after 2035 these types of vehicles will be the most expensive due to additional punitive charges that will be imposed by the state on car companies that still want to produce these types of internal combustion vehicles. There will be no restrictions or limitations for the purchase of vehicles powered by e-fuels, i.e. synthetic fuels whose combustion process will be emission-free. Technologies for the production of e-fuels based on water, hydrogen drawn from the atmosphere, the process of producing these e-fuels using electricity from large-scale renewable and emission-free energy sources already exist, but are expensive for the time being. But as there is still more than a decade to go until 2035, so there is enough time to adequately refine these technologies and make them widespread so that they become much cheaper. A rapid decline in the price of these new green e-fuel technologies over the next few years is possible. In the past, an analogous process has occurred for other green technologies. For example, the cost of photovoltaic technologies has fallen by almost 99 per cent in the three decades to 2019. In addition, the scale of restrictions on driving in certain public places, mainly in city centres for internal combustion vehicles, will increase in the coming years. Already, more and more cities are closing their city centres to combustion cars, starting with restrictions on this issue for cars powered by diesel and manufactured many years ago, as such cars are the most polluting and emit toxic chemicals, toxic especially to children.
In view of the above, I address the following question to the Honourable Community of scientists and researchers:
By 2035, will there be a significant decrease in the price and increase in the uptake of e-fuel technologies, i.e. synthetic fuels produced from water or hydrogen extracted from the air in a production process powered by renewable and emission-free energy sources?
Is it possible to switch the whole of European motorisation to electromobility by 2035, i.e. to realise the European Union's plan under which, after 2035, no new cars with combustion engines will be registered and put into service, and only zero-emission vehicles, i.e. electric and hydrogen vehicles, will be registered?
Is 12 years a long or short time to convert the whole of the automotive sector to electromobility, given both the green technologies and eco-innovations currently available in electromobility, hydrogen-powered vehicles, zero-emission production of hydrogen and other e-fuels, development of zero-emission energy sources, high recycling rates for electric vehicles, etc.?

The focus is on on investigating the social, economic, and environmental impacts of implementing sustainable transportation policies and initiatives. This includes studying the effects of promoting and encouraging sustainable transportation modes on various aspects of society, the economy, and the environment. It involves assessing factors such as changes in travel behavior, accessibility, air quality, greenhouse gas emissions, economic productivity, public health, and overall quality of life. By examining the holistic impacts of sustainable transportation measures, policymakers and researchers can better understand the potential benefits and trade-offs associated with sustainable transportation and make informed decisions to support long-term sustainability goals
When will large passenger drones powered by hydrogen engines and controlled by artificial intelligence be developed, mass produced and available to the public?
As part of the rapid technological progress that is taking place, new technological solutions, innovations and patents are being developed for use in various sectors of the economy and are improving manufacturing, production and service processes. On the other hand, due to the progressing process of global warming, the growing scale of natural resources consumption, the necessity to accelerate the processes of achieving the goals of sustainable development, the processes of green transformation of the economy, achieving the goals of environmental and climate policy, increasing the scale of protection of the planet's biosphere, biodiversity and climate, the demand for new eco-innovations and green technologies is growing. In the situation of combining new information technologies and Industry 4.0 with eco-innovations and green technologies, new opportunities arise for the application of new integrated, complex technological solutions and for increasing the effectiveness of the implementation of sustainable development goals and carrying out processes of green transformation of the economy, including the green transformation of the energy sector. The green transformation of the energy sector is mainly implemented through the development of renewable and emission-free energy sources. In addition, as part of the implementation of the plan to create a zero-carbon economy, it is also necessary to carry out a green transformation of the transport sector and this in all transport segments, i.e. land, water and air transport. As part of the green transformation of the air transport sector, new technological solutions are being developed to enable the use of engines to power aircraft based on solar energy or generated by burning hydrogen in oxygen. The future of powering large transport, passenger and space aircraft is hydrogen power. On the other hand, increasingly large drones are also being built, which are currently powered by electric motors that draw on electricity stored in batteries that need to be recharged. However, this may change in the future. With the combination of new technologies already being developed and tested in aviation, it will be possible to build, for example, large personal drones powered by hydrogen engines and controlled by artificial intelligence, so that they can be flown using autonomous automatic control, i.e. autopilot. In a hydrogen-powered situation, these would also be fully zero-emission, pro-climate and pro-environmental aircraft that could fly at low altitudes. This would greatly facilitate local transport over non-long distances, both passenger and freight. Such improvements in local air transport would be particularly important in areas where there are no airports, where there is no well-developed second-hand network and where, at the same time, people live in settlements far from large cities, in remote villages and small towns and in areas of strict nature conservation without the possibility of using vehicles with combustion engines.
In view of the above, I address the following question to the esteemed community of scientists and researchers:
When will large personal drones powered by hydrogen engines and controlled by artificial intelligence be developed, mass produced and available to citizens?

Will the current energy crisis accelerate the pro-environmental transformation of tourism and increase the scale of development of green, sustainable tourism?
Rising fossil fuel prices, energy prices are increasing interest in the development of renewable energy sources, increasing pressure to increase energy independence and diversification of energy sources, the application of new energy technologies in economic activities, eco-innovations that generate savings in the consumption of fossil fuels, switching to more energy-efficient means of transport, to electromobiles. In this way, the current energy crisis may perpetuate trends already underway, which are an offshoot of the long-term developing climate crisis. The pro-environmental trends of scaling up the implementation of sustainable development goals, the implementation of eco-innovations and green energy technologies into economic processes, which have been developing as important elements of the green economy, counteracting the progressive process of global warming and the worsening climate crisis are now being exacerbated by the developing energy crisis. The growing pro-environmental and pro-climate awareness of citizens may also force a change in the business models of tourism companies, which will increasingly enrich their tourism service offers with sustainability, pro-environmental, pro-climate, environmental protection issues, including, among others, through the use of emission-free energy sources, electromobility vehicles, etc. The effect of such pro-environmental processes may also be to add issues of sustainability, pro-environmental action, climate protection and planetary biosphere protection to the missions of tourism companies. The effect of such paradigm shifts and business models may be to change the standards of the means of transport used in tourism, increase the use of zero-emission transport and thus accelerate the pro-environmental transformation of tourism. Perhaps the consolidation of such processes in the years to come will increase the scale of development of green, sustainable tourism.
In view of the above, I address the following research question to the esteemed community of researchers and scientists:
Will rising fossil fuel, energy prices cause a change in the standards of the means of transport used in tourism, increase the scale of use of zero-emission transport and thus accelerate the pro-environmental transformation of tourism and increase the scale of development of green, sustainable tourism?
Will the current energy crisis perpetuate already developing trends of sustainable tourism development and increase the scale of pro-climate awareness among citizens?
Will the current energy crisis accelerate the pro-environmental transformation of tourism and increase the scale of green, sustainable tourism development?

When will the green transformation include avionics? When will hydrogen-oxygen-fueled aircraft be developed? When will emission-free aviation based on hydrogen-oxygen jet technology be developed? When will passenger and cargo planes powered by hydrogen-oxygen jet engines be built?
Since space shuttles, which were already built several decades ago, flew to the planet's orbit and were powered by hydrogen-oxygen fuel, it should be technically possible to build passenger and cargo planes powered by hydrogen-oxygen jet engines.
With the urgent transition to a zero-carbon economy, there is growing pressure to extend the green transition to avionics as well, i.e. to build zero-emission, zero-greenhouse-gas-emitting aircraft, and hydrogen-oxygen jet engines are such a solution. In the future, as part of the zero-carbon economy, such technological solutions should become widespread, and thus the green transformation should also include the aviation sector. The question then arises, when will this happen? When will avionics also be pro-environmentally transformed as part of the pro-environmental transformation of the economy and reduction of CO2 emissions into the atmosphere?
Is it possible to build passenger and cargo aircraft powered by hydrogen-oxygen jet engines?
Is it possible to build transcontinental space passenger aircraft powered by hydrogen-oxygen jet engines?
Is it possible to also build small jet passenger and cargo aircraft powered by hydrogen-oxygen engines?
Will avionics also be pro-environmentally transformed as part of a pro-environmental transformation of the economy and reduction of CO2 emissions into the atmosphere?
When will the green transformation also include avionics?
When will emission-free aviation be established?

I am currently working on my research topic on “Safe Urban Mobility”. I mean by “Safe” which ensures no transmission the infections during transport journeys in the time of the pandemic (Covid-19), especially with the poor mobility choices.
After searching the literature, I got a few studies pointing to the topic.
You can view and discuss your perceptions on this topic.
I welcome all opinions.

Kindly answer in the light of next 5 years or so.
Intelligent transportation systems provide many advantages as part of our daily lives. One of the most common applications of these current and increasingly widespread systems in our cities is intelligent junction control. The scope of the intelligent junction control concept which includes different approaches and algorithms, is quite wide. It is known that it needs realistic and objective technical knowledge to guide decision makers correctly. In this sense, what do you think the definition of intelligent intersection should include? Is a high-cost intersection control system with a lot of equipment always necessary? Or are the lower cost solutions that enable multi-plan control by only increasing the number of control programs? What should be the threshold or the transition point for the preference? Is it sufficient to make only cost-benefit analysis? To what extent should social benefits be taken into account for feasibility analysis? Sharing your views on this issue can be beneficial to many researchers and interested parties and can contribute to the spread of sustainable transportation (traffic management) systems.
Dear Colleagues,
The planning, design, and management of a transportation system require the nature and extent of the relationships between transport and the environment to be understood and quantified. Further, the strategies and actions needed to alleviate the different externalities linked to the transport of people and goods must be defined. Within this context, the “universe of transport” is changing at a speed never seen before, driven by impetuous technological development and affected by continuous changes in users’ needs, behaviors, and expectations.
New emerging mobility paradigms are becoming both a business opportunity and a social opportunity, as well as a strategy to increase the sustainability of the transportation system (e.g., shared mobility, Mobility As A Service). The availability of a huge quantity of data (big data) has given rise to different transport system modeling and simulation approaches. Moreover, the rapid and wide market penetration of several information sources and of Intelligent Transportation Systems/infrastructures is changing the usual travel and driving behaviors (e.g., ATIS, ADAS, real-time intersection synchronization). Finally, the new automotive and communication technologies will change the traditional way of “moving” in a road network (e.g., electric/hybrid vehicles, connected vehicles V2V or V2I, automated vehicles, autonomous vehicles).
The overall objective of this Special Issue of Sustainability is to collect original and innovative contributions focused on modeling and simulation methodologies/tools supporting the design and management of a greener, safer, and more equitable transportation system.
Theoretical and applicative contributions may include, but are not limited to, the following areas:
- Connected and automated vehicles (solutions, market penetration, and real impacts on transport systems);
- Real-time vehicle management (technologies, methodologies, issues, solutions, and perspectives);
- Driving assistance technologies (issues, solutions, and perspectives);
- V2V and V2I communication (issues, solutions, and perspectives);
- Alternative fuel vehicles (solutions, market penetration, and environmental impact);
- Optimization of transportation systems;
- Simulation of transportation systems;
- Vehicle routing and route planning;
- Travel demand modeling and management;
- Real-time network optimization;
- Real-time public services optimization,
- Real-time signals setting design or traffic control;
- Mobility as a service,
- Shared mobility,
- Intelligent information systems,
- Smart city logistics,
- Energy consumption modeling and simulation of innovative powertrains.

Dear researchers,
I am looking for information how Oslo is financing the development of sustainable city transport (any reports, strategies?) Moreover how urban transport is changing in terms of green mobility (qualitative and quantitative data). I will be grateful for your contribution
I am interested in examples of how the data revolution is already being used to drive more sustainable cities as well as ideas of new ways to leverage the data revolution for more sustainable and equitable cities. One of the main contributions of the data revolution id the creation of new data. My question is intended to ask - how such new alternative data could better inform approaches to solving the major sustainability challenges facing cities e.g. building energy inefficiency, inequitable access to waste, transport, housing, and other critical services by the poor, and excessive un-sustainable consumption by the rich. Do researchers have good examples of how alternative data from social media and data exhaust has been used to inform sustainability challenges? Thanks.
What are the main concerns/issues for the small- and medium-sized cities in planning and implementation of ELECTRIC bike-sharing & car-sharing stations from both spatial (location of a station) and power source points of view?
How does Sustainable transport link with Breaking new ground?
It is significant focus on the electrification of transport. Car-makers roll out a number of new models with battery range similar to Tesla.
Even planes are assumed be electric in few years on shorter routes.
On the other hand hydrogen is again focused as a storage medium for excess renewable energy production and possible use in transportation.
There are concerns about the environmental impact and many raise the question: "how-green-are-electric-cars?" An example is found in the link below.
What could be the development and final solution for the segments: Cars, trucks, buses, marine and air transport?
Do you foresee any breakthrough of alternatives?
I am interested in topic on Low-Carobon Future and in that regard I would like to know more on green and sustainable transport.
I looking for elements of BRT that support sustainable transport leading to sustainable city in terms of improving the environment/climate change.
Postman is one who moves door-to-door and delivers mail (written communication) and small packets. Postman usually moves on foot or a bicycle (environmental friendly modes) considering the nature of movements associated with delivery of mail. However, the roles of postman is slowly changing over the period, during last decade or so, especially post development of communication facilities such as e-mail and resultant decline of hard copy mail. Today postman not only delivers mail (that for which there is an essential requirement of a hard copy) that is mostly flowing between individuals and business / government establishments but is also handling delivery of e-commerce goods and resultant collection of money (as part of cash-on-delivery). The origin of postman being post + man may over a period be replaced by courier or any other word considering the changing roles of the person termed postman. In this light ‘postman’ and ‘postmen’ may become obsolete words. The modes postmen use constitute active travel modes and are part of the overall sustainable transport modes which are gaining greater attention currently.
Therefore, can ‘postman’ and ‘postmen’ have a new avatar or meaning based on the modes postmen used or are using even today?
That is, the words ‘postman’ and ‘postmen’ can represent transport planners associated with the planning of modes used by postmen. This allows societies to remember, postmen who have served our communication needs for the past century plus, for longer duration in future. The reasons for which are the two words can be expanded as illustrated below.
POSTMEN - Planner(s) Of Sustainable Transport Modes caring Environmental Needs
POSTMAN - Planner(s) Of Sustainable Transport Modes And Networks
I'm working on sustainable transport and its components. That is why I'm looking for methods that can be used to rank communication quality, its accessibility, range and surroundings (the look of the stops, land use and path quality on the way to the stop) when it comes to public transport system.
I need it for my literature review for planning strategies in implementing non-motorization as a sustainable transport? I only have one and is published way back 1995 by the Florida Department of Transportation.
Sustainable transport achievement bears on integration of modes. but the fragmentation of limited capacity modes in developing countries threatens urban transport sustainability. am thinking of possible, and economical (for the developing countries) frameworks for achieving transport sustainability through integration of modes.
Economic growth in metropolitan urban areas in developing countries is resulting in increasing demands from companies for goods and services. In fact, Governmental regulations aim decreasing mainly traffic congestion, although many others problems have emerged. Are these regulations enough? Which regulations are the most relevant/necessary in freight distribution system?
