Greenhouse gas emissions (GHG) per unit of milk produced show a clear and favourable downward trend after 2013. The target value for 2022 (< 0.704 kg CO₂ eq per kg milk) was achieved. In beef production, the trend in emissions intensity after 2014 is favourable, but somewhat insufficiently intensive. It is not yet possible to comment on the achievement of the target, as the indicator, including the proposal for the target values for the period 2022–2030, was not proposed until 2023.

The daily mobility of the population is a fundamental indicator of the performance and development trends of the transport system, and it also indirectly reflects the impact of the transport system on the environment - the greater the use of sustainable travel modes, the lower the impact of the transport system on the environment. In 2021, a resident of Slovenia made an average of 2.2 trips per day, the length of the trip was 31 km on average (27 km in the EU) and it took approximately 52 minutes (80 minutes in the EU).

The estimated value of external transport costs in 2021 is approximately 2.4 billion euros, accounting for 4.6% of Slovenia's GDP. The majority (99%) of these costs are attributed to road traffic, while only 1% is attributed to rail traffic. Two-thirds of external costs arise from passenger traffic, with the remaining one-third from freight traffic. Notably, a third of the external costs of transport are associated with traffic accidents, followed by costs related to congestion (20%), climate change (18%), air pollution (16%), damage to habitats (7%), and noise (6%).

Total revenues from taxes/charges from road, rail and inland water transport in the EU28 amounted to EUR 370 billion in 2016. This is approximately 2.5% of EU28 GDP in 2016. Aviation and maritime revenues are calculated only for a set of selected airports and ports, so it is not possible to determine the share of these revenues in total aviation and maritime tax/charges revenues of transport in the EU28.

The intensity of final energy consumption as well as sectoral intensities in Slovenia have decreased over the period 2005-2022. Most in industry, least in transport. Comparison with the EU-27 shows that Slovenia is worse than the EU-27 average, but the gap has almost halved over the period 2005-2021, with contribution of all sectors except transport.
