As a government-owned company, SBB is aware of its responsibility in tackling climate change and relies on renewable energies.
The company intends to reduce its greenhouse gas emissions from fuels, combustibles and coolants by 50% net by 2030 compared to base year 2018 and by 92% net by 2040. This reduction is an economically viable aim for SBB because of the generally higher efficiency and lower energy prices of renewable energies compared to fossil fuels.
SBB trains already draw 90% of their energy from hydropower. The remaining 10% is nuclear power. By 2025, all rail power is to come from renewable sources. In addition to ensuring guarantees of origin for renewable energy supplies, which is standard practice in the industry, SBB will also physically generate electricity to ensure the remaining 10% can be sourced from its own facilities or at least from facilities under contract.
