Abstract The significance and importance of road freight transport in society are certainly unquestionable. As in most sectors of the economy, road freight transport has an impact on the environment. The EU seeks to eliminate, as far as possible, the negative environmental impacts of various sectors. For these reasons, several EU commitments have been made in the future to reduce emissions so that road haulage vehicles are also more environmentally friendly. Trucks that use alternative fuels, such as natural gas, are already in use today. The EU attaches importance to reducing CO2 production, and this contribution also pays particular attention to the production of CO2 vehicles using liquefied natural gas (LNG) fuel compared to vehicles using standard diesel. The results show that when operating vehicles using LNG, it is possible to achieve lower CO2 production and at the same time lower vehicle noise, which is an advantage when operating vehicles in cities.

In the past few years, tools have been developed based on different communication means with the purpose of achieving a safer, more efficient, and environment-friendly operation of vehicular flows in the transport systems. Some of the early means generally involved a very strong human participation. In the course of time and with the rapid progress made in electronics, telecommunications, and computer systems, such processes have become automated until generating a series of technologies that currently are incorporated into the single generic term of intelligent transportation systems (ITS). This research has multiple purposes. First, some characteristics of road freight transport in Mexico are presented. Then, with such characteristics under consideration, the ITS technologies with the largest potential for application to that transportation type are described. A vision of future implementation is shown. Finally, some conclusions are presented.

The 2030 Climate target plan of the European Commission (EC) establishes a greenhouse gases (GHG) emissions reduction target of at least 55% by 2030, compared to 1990. It highlights that all transport modes—road, rail, aviation and waterborne—will have to contribute to this aim. A smart combination of vehicle/vessel/aircraft efficiency improvements, as well as fuel mix changes, are among the measures that can reduce GHG emissions, reducing at the same time noise pollution and improving air quality. This research provides a comprehensive analysis of recent research and innovation in low-emission alternative energy for transport (excluding hydrogen) in selected European Union (EU)-funded projects. It considers the latest developments in the field, identifying relevant researched technologies by fuel type and their development phase. The results show that liquefied natural gas (LNG) refueling stations, followed by biofuels for road transport and alternative aviation fuels, are among the researched technologies with the highest investments. Methane-based fuels (e.g., compressed natural gas (CNG), LNG) have received the greatest attention concerning the number of projects and the level of funding. By contrast, liquefied petroleum gas (LPG) only has four ongoing projects. Alcohols, esters and ethers, and synthetic paraffinic and aromatic fuels (SPF) are in between. So far, road transport has the highest use of alternative fuels in the transport sector. Despite the financial support from the EU, advances have yet to materialize, suggesting that EU transport decarbonization policies should not consider a radical or sudden change, and therefore, transition periods are critical. It is also noteworthy that there is no silver bullet solution to decarbonization and thus the right use of the various alternative fuels available will be key.

The installed capacity of boiler units in Ukraine significantly exceeds the needs for consumers was shown. The remarking of boiler units to lower capacity is the one of the least capital-intensive ways to increase their technical, economic, environmental indicators and the extension of their resource. To achieve EU norms it is necessary to reduce emissions of NOx by 50–80 % for boilers of LCP with an capacity a rated thermal input of 50 MW or more, which operate on natural gas has been established. An increase the concentration of recirculation gases in blow air of more than 25 % of all exhaust gases significantly reduces the concentration of oxygen in the mixture of air and exhaust gases. It’s can cause to: deterioration of combustion, the removal of a torch into the convective part, a significant increase electricity consumption and increase the temperature of the exhaust gases. The using of CO2 or N2 gases for balancing natural gas to reduce NOx emissions is economically impractical. The using of ballasting technology, which based on mixing exhaust gases with natural gas, requires special burners, due to the range of burner power control must be limited. To reduce NOx is advisable to combine several measures simultaneously. The plan an action to implement EU environmental directives by existing boiler units operating on natural gas with an increase their technical and economic indicators has been developed. There is one of the possible ways to implement the EU ecological directives by boiler units in Ukraine, it’s transferring the load from existing LCP with a rated thermal input of 50 MW or more to less powerful ones. For remove combustion plants from the requirements of the EU Directive 2010/75/EU, it is necessary to remark part of the boilers for a new nominal capacity for the purpose of obtaining combustion plants a rated thermal input of less than 50 MW.

Priorities for a competitive and efficient EU transport system have been declared in the third White Paper published in 2011. The strategic priorities of European transport policy are integrated to other EU development priorities, including the European Green Deal, Territorial Agenda 2030. In December 2020 The European Commission presented “Sustainable and Smart Mobility Strategy – putting European transport on track for the future”. This document has outlined the European transport system’s path towards achieving objectives of a sustainable, smart and resilient mobility. The priorities of the European transport system focus on environmental issues, sustainability, development of high-speed railways, expansion of rail freight and passenger transport markets, development of multimodal transportation, technologies for a further electrification and automation in transport, digitalization, deployment of innovations. Road freight transport accounted for more than two thirds of freight traffic in 2019. For the EU member states bordered to Ukraine (Poland, Slovakia, Hungary, Romania), the share of road freight transport has been growing since 2011. These countries are mostly involved in the international road freight transportation. The average distance for which goods were carried by international road freight transport in EU was 581 km in 2018. For Poland, Hungary, Slovakia and Romania the average distance varied from 603 to 786 km. The countries that have joined the EU since 2004 accounted for 80 % of all cross-trade in the EU, which emphasized on the relative competitiveness of hauliers from these countries. Transport companies from Poland are the most active in freight transport between EU countries, in particular in cabotage. In 2020, the European Parliament adopted the Mobility Package I. However, some Members of EU countries, including Poland and Romania claimed against some statements of the Package, including the driver returns home and rules on cabotage operation.

Measures taken to handle the COVID-19 epidemic in the spring of 2020 have had a significant impact on European supply chains. In terms of freight transport, this has led to a decline and congestion in truck traffic due to different restrictions on the internal borders of the EU. As similar situations cannot be avoided in the future, it is worthy to form supply chains that are less affected by different epidemics. Similarly to the physical internet hubs, distribution hubs can be forward-looking, but only if it helps development of rail-road intermodal freight transport. The article describes the possibility of a rail-road freight transport system that allows the application of radically new solutions through a new container handling technology that can be used in the rail-road relationship. The extension of the idea at the EU level could result in a significant increase in the share of rail freight and a sizeable reduction of the negative impact of epidemics on the supply chains. Among other effects, the solution can have a significant impact on the IT development of rail freight transport. The solution can also have effect to the development of the network of rail-road intermodal trans-shipment points, their automation and ultimately the completion of Logistics 4.0.

Road freight transport contributes to a significant and growing share of greenhouse gas emissions. This study analyses the development of environmental practices and awareness of road freight hauliers and whether hauliers witness an interest from their shippers towards energy efficiency. Results of an original survey (N = 256) conducted in 2019 among Finnish hauliers are presented and compared with those from a similar survey completed in 2011 (N = 295). The results highlight the lack of improvement in hauliers’ environmental practices during a decade when ambitious climate goals were set. Even though hauliers share the view that emissions from road freight transport must be reduced in future, their environmental practices did not change much during the 2010s. The hauliers rarely perceive an interest from their shippers towards energy efficiency. The results show that hauliers should be supported and encouraged to pursue more environmentally aware practices. Shippers in the supply chain should be a driver, not an obstacle, to increasing road hauliers’ sustainability. There should be more communication between hauliers and supply chain actors, and environmental sustainability should gain more importance when selecting carriers.
