In 2024, 67% of the population was connected to municipal wastewater treatment systems with secondary or tertiary treatment that cause minimal GHG emissions. Compared to the previous year, the share increased by almost 2 percentage points. Compared to 2017, the share increased by 5.4 percentage points.

By 2025, the implementation of energy efficiency (EE) and renewable energy measures (RES) in the public sector resulted in total annual energy savings of 365 GWh, and the total annaul CO₂ emissions reduction was 92 kt. Investment activity declined in 2025 due to the transition from one financial perspective to the other. In that year, energy savings amounted to 16.8 GWh and the CO₂ emissions reduction was 5.3 kt, which are the lowest levels recorded in the 2018–2025 period. No 2030 targets have been set for this indicator.

In 2024, 83.1% of all heat in district heating (DH) systems was produced in energy-efficient district heating systems, i.e. systems meeting at least one of the criteria defined in Article 50 of the Energy Efficiency Act (ZURE). Compared with 2023, this share decreased by 4.5 percentage points. The combined share of heat from renewable energy sources and waste heat amounted to 20.5% in 2024, which was 0.7 percentage points lower than in the previous year, but 4.8 percentage points higher than in 2016.

In 2025, the leverage of incentives in the public sector amounted to 32.9 euro cents of subsidy for 1 euro of investment, which was 21 euro cents less than in 2024. The decline was due to the projects supported by the Eco Fund under the calls for co-financing new investments in the construction of highly energy-efficient, nearly zero-energy buildings of general public interest. For these projects, the leverage of incentives was only 13.3 euro cents of subsidy for 1 euro of investment, while they accounted for as much as 73% of the total value of supported investments.

Final energy consumption in 2024 amounted to 4,594 ktoe and increased by 2.4% compared to the previous year. A decrease occurred only in households, by 1.6%; in all other sectors, final energy consumption increased: by less than one per cent in industry, by 2.8% in services, and the most, by 5.3%, in transport. Final energy consumption was 177 ktoe (- 3.7%) , or 3.7%, lower than the 2024 indicative target value from the National Energy and Climate Plan from 2020 (NECP 2024). The indicative annual target was thus achieved.
