Climate change

BLS aims to achieve net-zero emissions by 2050 at the latest
Climate change is one of the greatest challenges of our time. As a mobility provider, BLS is aware of its social role and responsibility and is therefore working to adapt to the unavoidable consequences of climate change, actively contribute to climate protection and gradually increase its energy efficiency.

Adapting to climate change

The implementation of measures to adapt to climate change is an essential part of the strategy to ensure the long-term functionality and safety of the rail network, including in an environment made increasingly challenging by climate change. The focus here is on structural measures for the infrastructure and changes to the protective forest.

Climate protection

BLS is continuously improving its climate and environmental footprint. This includes increasing energy efficiency and achieving net zero with the following milestones:

Net-zero scope 1 & 2 emissions in Switzerland by 2040 (in shipping by 2050)
Net-zero scope 1 & 2 emissions abroad by 2045
Net-zero scope 3 emissions by 2050

In 2025, BLS, in collaboration with its divisions and subsidiaries, developed the first version of the CO₂ reduction pathway for Scope 1 and 2 emissions, with the aim of setting interim targets and outlining the expected trends from the base year 2022 through to 2050. The current reduction pathway for BLS AG reflects the CO₂ reductions resulting from the planned measures.

Energy

Measures to increase energy efficiency and the use of renewable energies play a central role in the context of climate change. BLS is pursuing several measures in the area of energy: The modernised Bönigen workshop is based on a comprehensive energy strategy featuring a large-scale photovoltaic system and a sustainable seawater system; the system reduces CO₂ emissions by around 550 tonnes annually. In addition, BLS is exploring the potential for installing photovoltaic systems on buildings, noise barriers, open spaces and other surfaces, as well as converting heating systems to renewable energy sources.
