Slovenia’s Public Transport: A Quick Guide

Navigating Slovenia without a car is not only feasible but also a rewarding experience, especially for the eco-conscious traveler. The country boasts a well-organized and efficient public transport network, primarily relying on trains and buses to connect its cities and towns.

Trains

• Slovenian Railways further clarifies these figures: a passenger train emits 0.0355 kg CO₂e/PKM compared to a personal car's 0.1669 kg CO₂e/PKM.
• Remarkably, rail transport accounts for only 0.4 percent of greenhouse gas emissions from transport, underscoring its efficiency.
