In the last decade (2012–2021), on average around 135,000 tons of hazardous waste was generated annually in Slovenia. This waste accounted for 1% to 3% of all generated waste in Slovenia. Since they contain substances harmful to the environment and health, they must be collected, recovered or disposed of separately from other waste.

In the last decade (2012–2021) each resident of Slovenia annually discards on average around 3.5 kg of hazardous municipal waste, of which the majority in waste electrical and electronic equipment (63%).

Electricity consumption in households is increasing, especially in the last two years, and in 2021 it amounted to 3,803 GWh. The share of households equipped with goods that require electricity for their operation is also increasing. For example dishwasher, tumble dryer, mobile phone, microwave oven, personal computer as well as heat pump and air conditioner.

In Slovenia, in 2020 the external costs estimate of electricity production ranges from 0.8 - 2.8 € c2000 / kWh. Despite growing environmental awareness, the price of electricity still does not reflect all external costs. Due to incorrect price signals, which are the result of the current situation on the electricity markets, energy sources in Slovenia remain suboptimally used.

Slovenia has a fairly high level of energy intensity that is decreasing, especially in the last few years. Average yearly decrease rate in the period 2005-2021 was 2.7 %. Compared to EU-27 Slovenia had 37 % higher intensity in 2020, being 11 % points lower than in 2005.

Air pollutant emissions have decreased in the period 2005−2020 to the levels that enable Slovenia achievement of its 2020 targets. But to reach 2030 targets additional decrease is needed. Reduction of emissions contributed to lower impact on ecosystems and human health, as emissions of pollutants that contribute to acidification, ozone precursors and particles, decreased by half compared to 2005.
