The public passenger transport company LPP and the public energy company Energetika Ljubljana have significantly enhanced their contribution to an environmentally sustainable future in Ljubljana.
As part of the goals of the Mission 100 climate-neutral and smart cities by 2030, they converted the first bus from the existing LPP fleet running on compressed natural gas (CNG or methane) by replacing its original fuel with biomethane. This made the vehicle carbon neutral, which represents an important milestone on the path to the green transformation of urban passenger transport.
Biomethane is produced from biogas formed by organic waste and is thus renewable and chemically identical to natural gas. Using biomethane reduces the carbon footprint of urban buses by leveraging existing gas infrastructure without extra investment. This allows the current methane bus fleet to gradually switch to a cleaner energy source.

Ljubljana’s efforts don’t stop there. This year, the delivery of eight hydrogen buses, and next year as many as 25 electric buses are expected, bringing the city even closer to the goal of carbon neutrality.
This breakthrough is the result of a partnership between two public companies from the Public Holding Ljubljana, Energetika Ljubljana and LPP, which, through their development activities, significantly contribute to the implementation of commitments to reduce the carbon footprint in Ljubljana.
The city encourages residents and visitors to choose to travel by bus as often as possible, as every choice of public transport makes an important contribution to cleaner air and a better quality of life in Ljubljana.
