The Tool for Reflecting on the Real Impact of Transport

Comprehensive Assessment of the Environmental Impact of Transport
CarbonTrack360 is a tool (web application) developed by Ineco to analyse and compare the environmental impact of air and rail transport in Spain from a full life cycle perspective. Unlike other approaches that only consider emissions during operation, this methodology includes key phases such as construction, maintenance, and (in the future) renovation and dismantling.
In high-speed rail, 95% of emissions are generated during construction, whereas in air transport, 97% occur during operation.

A vision of the Spanish network
In the last three decades, Spain has undergone an impressive process of modernising its transport infrastructure. The inauguration of strategic airport terminals, together with the development of high-speed rail, has consolidated a modern network that began its transformation with the construction of the motorway network that started in the 1980s. Understanding its impact from a broad perspective is essential for designing effective strategies towards a truly sustainable transport future.
This analysis focuses on the GHG emissions specifically generated by mainland air transport and high-speed rail, leaving aside other modes of transport and activity segments to obtain more precise and comparable results.


Rigour for a realistic analysis
CarbonTrack360 has served as a valuable framework for reflection, enabling the extraction of meaningful insights into the climate impact of various modes of transportation.
It has been shown that air transport concentrates the majority of its emissions during the operational phase, while high-speed rail, despite operating with 100% renewable energy since 2019 and having almost zero emissions in operation, presents a high impact during its construction.
Furthermore, the climate efficiency of the train depends on achieving a sufficient accumulated demand over time, and thresholds have been identified to determine when this mode of transport becomes more environmentally efficient in terms of emissions.
