This study explores the links between ICTs, transport, and CO 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.
本研究探讨了信息通信技术、交通运输与一氧化碳排放之间的联系。尽管运输活动对环境质量有有害影响,但这一重大问题在科学上受到的关注较少。在这方面,我们探讨了通过将新技术与货运活动(即内陆运输、铁路运输和航空运输)相结合来减少环境破坏的可能性。基于2002年至2014年期间43个国家的数据,实证技术采用了两步系统广义矩估计法(GMM)。总体而言,结果非常令人振奋,证实了信息通信技术一旦在运输部门得到良好应用,就有能力抑制污染。首先,就环境可持续性而言,电话和移动电话在铁路和内陆运输部门使用时是最有效的技术,而互联网在航空运输部门得到了最佳利用。其次,电话在与多式联运相互作用时起到了加速器的作用,从而更好地改善环境。本研究还考虑了公共政策及其影响。
