Businesses nowadays are pressured to operate in a more sustainable way and consider economic as well as environmental and social logics behind their business practices in order to create value for their stakeholders. In consequence, a sustainable business model has been implemented in both goods and service industries and offers a framework for system level innovation for sustainability though the whole supply chain management (Bocken & Short, 2015; Hogevold, Svensson & Padin, 2015).In the transportation industry, the focus on sustainability and new business models is also increasing (Dekker et al, 2012). This industry has by far one of the most negative environmental impacts and road transportation is the biggest concern of all transport modes (Jaegler and Condran, 2014). Trucks are remaining to dominate in the long-haulage deliveries in many countries hence understanding sustainable business models in this industry is important both for practice and academia. Also, with the customer pressure, global political agenda and changing systems, the companies should consider addressing sustainability challenges combining different business actors and stakeholders in joint value-adding offerings (Seuring Hahn & Gold, 2013).With the present focus of high-end heavy-vehicle manufacturers to provide sustainable solutions to their customers the question arises: what do they mean by this? The purpose of this study is to explore new business models and interactions in transport network, focusing on trucking industry (specifically on long-haulage) with the focus on emerging sustainability issues. Since long-haulage trucks are the big part of transportation system, the focus is on truck manufacturers, dealers and truck buyers. The empirical base for this study is multiple case study of main truck manufacturers and their downstream network in Sweden and Australia. The research question of this study is: what is a sustainable business model in long-haulage transport supply chains? What are the main components in the business model that can be called sustainable? The study is designed as a qualitative study with the goal to collect the data through personal interviews (Myers, 2009).This paper consists of theoretical discussion on sustainable business models with the focus on the industrial networks. The theoretical lens chosen is social network theory and stakeholder theory. The methods section includes the description of the study performed. The empirical part consists of data extracted from the interviews with three heavy-vehicle manufacturers, dealers and transport customers. The analysis part and conclusions explain the model for sustainable business model in long-haulage transport supply chains. The paper is finalized with managerialand theoretical contributions and directions for future research.
