Total GHG emissions in the ETS sector recorded an annual decrease for the sixth year in a row. In 2023, they decreased by almost 6% and reached the lowest value in the observed period. The decrease is mainly a result of much lower GHG emissions across all groups, the most in manufacturing industries and construction group. At the EU level, a legally binding target of reducing GHG emissions by 62% by 2030 compared to the 2005 level has been adopted for the ETS sector, which is a common target for the EU and is not further differentiated by member states.

In 2022, taking into account only the production of energy from RES in Slovenia, Slovenia achieved a 22.9% share of RES in gross final energy consumption. To achieve a binding 25% national target share of RES under the Directive 2009/28/EC, Slovenia purchased the missing production from RES. In 2023, the share of RES in gross final energy consumption was 25.1%, which is 5.3 percentage points more than in 2005. The increase in the share of RES in 2023 is the result of an increase in the use of RES in the electricity production sector.

In 2022, greenhouse gas (GHG) emissions from sources according to the Regulation (EU) 2018/842 increased by 3.2% compared to the previous year, but in 2023 they decreased by 4.4% and were 7% below the annual target set by Regulation, thus achieving the indicative annual value. The 2030 target set by the National Energy and Climate Plan from 2020 (NECP 2020) is more ambitious and in 2023 the indicative annual value set by the NECP 2020 was not achieved, lagging behind by 0.5 percentage points.

In the period 1992–2023 nitrogen surplus in Slovenian agriculture decreased. Trend analysis for this period shows that gross nitrogen surplus decreased on average by 1.4 kg N/ha per year or by 54%, and the net surplus by 1.2 kg N/ha per year or by 85%. The lower surplus was mainly due to a 43% increase in nitrogen removal by crops and a 6% decrease in nitrogen input per hectare of utilized agricultural area. A lower excess of nitrogen indicates better nitrogen management in agriculture and consequently a reduction in emissions of nitrogen compounds into the environment.

The frequency of agricultural drought in Slovenia has been increasing in recent decades. Since year 2000, natural disaster due to drought was declared seven times in Slovenia, the most severe of which occurred in 2003, 2012, 2013, 2017 and 2022. Drought keeps occurring with increasing intensity and in areas and seasons where there have not been problems in the past. An additional risk for drought damage in agriculture present rapidly developing droughts in summer (so-called "flash droughts"), which occur during heat waves.
