Last update: Sustainability Report 2021

Greenhouse gas emissions is a priority for the FS Italiane Group and all Group companies are involved in developing initiatives to this end.

In 2021, the Group’s CO2 emissions came to 2.06 million tonnes, just slightly under the 2020 total. The close connection between energy consumption and CO2 emissions is mirrored in the volumes and variations in the total and individual items. As a result, the pandemic also had a huge impact on greenhouse gas emissions in the past two years.

Other atmospheric emissions

The transport sector is also responsible for other emissions. Although the railway sector’s emissions are marginal compared to other environmental aspects, atmospheric emissions should in any case be monitored, also with regard to the environmental impact of the Group’s road transport services. Also in this case, nitrogen oxide and sulphur oxide emissions and particulates are mostly the result of combustion for road and rail passenger and freight transport, as well as shunting rolling stock. The FS Italiane group’s road transport companies are committing to upgrading the fleet, preferring more modern engines with significantly less harmful emissions.

Verification of greenhouse gas emission calculation method - ISO 14064-1:2018 certification

The FS Group has obtained certification under the ISO 14064-1:2018 standard, which attests to the quality of the quantification and calculation methodology of CO2 eq emissions for 2022 and the baseline year (2019).

FS Italiane, which is projected to achieve “Zero net emissions” by 2040, is acting fairly, accurately and transparently in its collection of data, calculation and reporting of greenhouse gas emissions. FS has surveyed the sources and types of emissions - mainly divided into direct emissions (such as those produced by its diesel trains, buses and ships) and indirect emissions (such as those resulting from the consumption of imported electricity for railway traction, materials and energy consumption in railway yards, employee commuting, and business travel).

The audit carried out by SGS Italy reaffirms the robustness of the decarbonisation process and the transparency of the Group’s sustainability goals.
