Development of battery technology is making battery electric heavy duty trucks technically and commercially viable and several manufacturers have introduced battery electric trucks recently. However, the national and sectoral differences in freight transport operations affect the viability of electric trucks. The aim of this paper is to develop a methodology for estimating the potential of electric trucks and demonstrate the results in Switzerland and Finland. Commodity-level analysis of the continuous road freight survey data were carried out in both countries. As much as 71% of Swiss road freight transport tonne-kilometers may be electrified using battery electric trucks but Finland has very limited potential of 35%, due to the use of long and heavy truck-trailer combinations. Within both countries the electrification potential varies considerably between commodities, although in Finland more so than in Switzerland. Commodities which are constrained by payload volume rather than weight and are to large extent carried using medium duty or <26t rigid trucks trucks seem to provide high potential for electrification even with the current technology. Electric trucks increase the annual electricity consumption by only 1–3%, but truck charging is likely to have a large impact on local grids near logistics centres and rest stations along major roads. A spatial analysis by routing the trips reported in the datasets used in this study should be carried out. Future research should also include comparison between the alternate ways of electrifying road freight transport, i.e. batteries with charging, batteries with battery swapping and electrified road systems.
This paper reports on research undertaken to determine the baseline trends in logistics and supply chain management and associated environmental effects up to 2020. Factors affecting freight ...transport demand, truck fuel consumption and related CO
2 emissions are classified into six categories in relation to different levels of logistical decision-making. The projections are based on the results of seven focus group discussions and a large-scale Delphi survey. Three scenarios are constructed to assess CO
2 emission levels from road freight transport in 2020. The likely changes in the key logistics variables are discussed and the complexity of the problem is highlighted.
Nowadays, environmental concerns have significantly influenced business management and societal practices, leading to a strong focus on minimizing environmental damage and embracing sustainable ...development. This has prompted the adoption of greener supply chain practices and the transition towards a circular economy (CE). Companies are under pressure to incorporate green innovation practices, aiming for environmentally friendly and low-carbon development. This research aligns with the principles of the CE, an emerging economic model that emphasizes resource preservation and energy efficiency. CE is also recognized as a key driver for achieving sustainable development goals. However, the road freight transport sector, which is vital for goods transportation, faces challenges in becoming more sustainable due to its significant greenhouse gas emissions. This study analyzes the feasibility of achieving both environmental and financial sustainability in the road freight transport sector in Portugal. This piece of research aims to determine if combining these two concepts is practically viable and explores how transitioning to a circular economy can generate value and enhance environmental sustainability in the sector.
Drawing upon the interview results, existing literature, and principles of the circular economy, an analysis was conducted to understand the current obstacles faced by companies in the sector and explore potential solutions. The main findings indicate that implementing the circular economy in the sector requires better technological advancements to ensure the use of fully renewable energy sources and facilitate the reuse of materials in vehicles. Additionally, it is crucial for all stakeholders to participate actively, as the transition to a circular economy is a structural change that necessitates collective efforts from everyone involved.

The problem of how to coordinate a large fleet of trucks with a given itinerary to enable fuel-efficient platooning is considered. Platooning is a promising technology that enables trucks to save ...significant amounts of fuel by driving close together and thus reducing air drag. A setting is considered in which each truck in a fleet is provided with a start location, a destination, a departure time, and an arrival deadline from a higher planning level. Fuel-efficient plans should be computed. The plans consist of routes and speed profiles that allow trucks to arrive by their arrival deadlines. Hereby, trucks can meet on common parts of their routes and form platoons, resulting in decreased fuel consumption. We formulate a combinatorial optimization problem that combines plans involving only two vehicles. We show that this problem is difficult to solve for large problem instances. Hence, a heuristic algorithm is proposed. The resulting plans are further optimized using convex optimization techniques. The method is evaluated with Monte Carlo simulations in a realistic setting. We demonstrate that the proposed algorithm can compute plans for thousands of trucks and that significant fuel savings can be achieved.
•The Canadian Net-Zero Emissions Accountability Act dictates Canada's commitment to achieve net-zero emissions by 2050.•This work shows that the electrification of 5 % and 75 % of heavy-duty trucks ...can save up to 0.9 and 12.9 million tonnes GHG, respectively.•This study suggests that Ontario's peak demand in 2040 for 5 % and 75 % heavy-duty truck electrification scenarios can be up to 27.5GW and 30.4 GW, respectively.
In this work, the new energy demand and greenhouse gas emissions that would be associated with heavy truck electrification in Ontario is evaluated. A new equation is derived to calculate the pollution-producing electricity generation based on the breakdown of the Ontario generation mosaic. Using this as a basis, for 4 scenarios of 5 %, 25 %, 50 % and 75 % of heavy-duty truck electrification, the Marginal Emission Factor (MEF) is calculated. This evaluation suggests that Ontario's peak demand in 2040 for the least and the most heavy-duty truck electrification scenarios can be up to 27.5 GW and 30.4 GW, respectively, compared to a baseline of 26.8 GW when assuming no heavy truck electrification condition. It is also forecasted that if the extra demand for electric trucks is supplied by clean renewable resources, the GHG emission reduction for 2040 can be as high as 0.9 MT, 4.3 MT, 8.6 MT and 12.9 MT GHG, respectively.
Transport is one of the most important economic sectors in the world. It is a fundamental and important element of a country’s GDP. Gross Domestic Product (GDP) is considered one of the most ...important indicators of economic performance of a country. GDP can be compiled for both a country and a region. Changes in technology and economic structure of the production system of an area are the central issues of long-term economic growth according to the increase in the gross value added of a region. In this paper, the authors focus on finding out how the development of road freight transport performance affects the economy of a region. At the same time, they try to answer the question to what extent transport regulation can influence the economic development of an area. The research is mainly focused on EU policies aimed at regulating road freight transport.
Companies in 2023 have to face many challenges and will have to face many challenges in the future, according to the current predictions of renowned agencies and institutions. The pursuit of ...financial stability for profit-seeking entities is undoubtedly one of the most critical. Achieving this is influenced by a number of factors, including sustainability factors. In addition to the generally applicable principles, respecting and implementing the sub-aspects of sustainability also has certain specificities. These may be determined, for example, by the sectoral affiliation of the company. The sector chosen in the following text will be the transport sector. The stability of the performance of this sector will be examined in relation to selected sustainability factors. As transport is one of the largest polluters of the environment, transport performance is examined in the context of air emissions. The examination is carried out at EU Member State level in the timeframe 2011 and 2021, in relation to the EU strategy for achieving the Sustainable Development Goals (SDGs).

The purpose of this paper is to elaborate the transport geography of electric and autonomous vehicles for road freight transport and establish a research agenda by identifying many unresolved issues ...already beginning to emerge. While regulatory approval for full coverage on all roads remains some years away, autonomous vehicles are already operating intermodal-style main hauls on major highways, interchanging at highway junctions with the first and last mile performed by regular trucks. Meanwhile, electric trucks capable of medium distances on a single charge are now entering the market. The two technologies of electric propulsion and autonomy are mutually reinforcing, particularly from the network perspective, and purpose-built electric autonomous vehicles (EAVs) are starting to enter commercial service.
This paper utilises an analytical framework of intermodal transport to map against the emerging geography of EAVs and determine how our knowledge of the features, challenges, business models and policy implications of intermodal transport can help decision makers plan for a better development of the emerging EAV network. The paper provides recommendations for policymakers dealing with arising challenges and identifies a list of research questions regarding this rapidly evolving new form of transport.
