In 2022, according to currently available data, the amount was further reduced to EUR 1.1 million.

GHG emissions in industry decreased slightly in 2021 compared to the previous year. Since 2009, there has been no noticeable trend of decreasing GHG emissions in this sector.

GHG emissions in the ETS subsector of industry sector decreased for the third year in a row and were 4.2% lower than the previous year. GHG emissions in the non-ETS subsector of the industry sector increased by 5.5% in 2021 compared to the previous year.

The performance of EU countries in the field of eco-innovations is monitored by a composite index that includes 12 indicators from five thematic areas. Slovenia is ranked as an average eco-innovation performer. The values of the indicator are gradually improving and show the progress of the eco-innovation index, but they still remain below the EU average. The target value for Slovenia has not been set.
