In recent years, energy taxes have increased mainly due to higher excise duties and taxes. The share of tax in the price of energy in industry has reached the same level as in the price paid by households. In Slovenia, taxes on transport fuels and electricity were below the EU-27 average, while taxes on natural gas in industry and households were above that average, exceeded only by Austria, Italy, Denmark and Sweden. 

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) comprise approximately 17% of the territory of Slovenia. Going by land use in these areas, forest (61.1%) prevails, followed by grassland (13.6%) and arable fields (10.9%). Ecologically farmed land represents only 1.7% of total WPAs and 6.04% of agricultural land on WPAs, with grassland representing the largest share at 79.6%.

In 2019, Slovenia's ecological footprint amounted to 5.23 gha per inhabitant, which places our country below the European Union average (5.42 gha per inhabitant). Carbon footprint contributes 56% of the ecological footprint, so it should receive comparatively more attention. A significant share of the ecological footprint is also represented by forest products (23.1%). According to the categories of consumption, housing and personal transport contribute the most to the ecological footprint in Slovenia. Goods is the category with the least contribution to the ecological footprint.

In 2021, the energy reduction in the energy efficiency obligation scheme (energy amounted to 610.4 GWh. A bigger share of the savings, 57%, was achieved through the implementation of energy efficiency (EE) and renewable energy source (RES) measures within the Eco Fund programs. The annual target value was exceeded by a third. For 2022, according to preliminary data, the achieved energy savings are estimated at 700.8 GWh, which is 15% more than the previous year and 53% above the target value.
