Abstract
This study explores the links between ICTs, transport, and CO2 emissions. Despite the harmful consequences of transport activity on the environmental quality, there is less scientific attention accorded to this major issue. In this regard, we explore the possibility of reducing environmental damages through the association of new technologies with freight transport activities (i.e. inland, rail, and air). The empirical technique based on 43 countries between 2002 and 2014 employs the 2-step system Generalized Method of Moments (GMM). Overall, the results are very ambitious confirming the ability of ICT in dampening pollution once it's well adapted in the transportation sector. First, the telephone and mobile phones are the most efficient technologies in terms of environmental sustainability when used in the rail and the inland transport sector, while the internet is best utilized in the air transport sector. Second, the telephone plays the role of an accelerator when interacting with intermodality to better improve the environment. Public policies and their implications are considered in the study.
Highlights
Transport systems actively contribute to the socio-economic development of countries
This study examined the interactive association relating ICTs to freight transport to influence CO2 emissions over the period 2002–2014
ICT refers to the internet, mobile phones, and telephone penetration levels, while freight transport is approximated in terms of rail, inland, and air freight transport
Summary
Transport systems actively contribute to the socio-economic development of countries. Despite relevant efforts made in other sectors of the economy, pollution has increased for the transport sector, and its eventual reduction appears prohibitively expensive because the system and the global economy as a whole is highly dependent on fossil fuel consumption and associated infrastructures (Uddin, 2012; Santos, 2017; Chatti et al, 2019). Both governments and transport companies have attempted to profit from some innovative solutions to dampen energy consumption, and reduce the environmental degradation associated with their activities
