Although electricity and heat generation increased by 30% between 1990 and 2021, CO2 emissions decreased by 31.5%, mainly due to the increase in generation efficiency, as well as to the increase in RES and nuclear generation. SO2 emissions decreased by almost 99%, mainly due to the installation of desulphurisation, the increase in generation efficiency and share of RES and nuclear generation.

Water protection areas (WPA) cover 17.4% of Slovenia's territory. The land use structure in water protection areas is dominated by forest (62.1 %), followed by grassland (13.5 %) and arable land (10.5 %). The amount of built-up land in the water protection areas is increasing, while a decrease in arable land and an increase in the share of organically farmed land indicate positive changes in the direction of extensification of land use.

Since 2012, the installed capacity of the systems for the production of electricity from RES has increased by 47.3%. More than half of this increase, 24.7%, was achieved in the last three years. The indicator is currently on a trajectory of achieving the indicative targets until 2030 set in the National Energy and Climate Plan (NECP).

According to the first estimates for 2022, GHG emissions per unit of electricity produced amounted to 208 gCO₂/kWh. In the period 1992–2022, the intensity of GHG emissions decreased by 52.8%. Compared to the EU-27 average, it was in Slovenia in 2022 17.1% lower.

Although a quarter of the newly registered personal cars in Slovenia are electric or hybrid, their share among all personal vehicles is only around 3%. This is due to the fact that households rarely decide to purchase new cars, resulting in a high average age of cars over 10 years, and it will take a long time for our vehicle fleet to become less energy-intensive. Slovenia ranks in the bottom quarter of European countries by the share of first registrations of new personal electric vehicles.
