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.

The total annual final energy savings due to the implementation of energy efficiency (EE) and renewable energy source (RES) measures in the residential sector amounted to 1,319 GWh in 2025, and the total annual CO₂ emissions reduction was 306 kt. Compared to the previous year, annual energy savings decreased by 39%, while the reduction in CO₂ emissions fell by as much as 45%. Lower values were only achieved in the period before 2019.

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.

From 2012 to 2024, the installed capacity of the systems for the production of electricity from RES has increased by 78,5%. More than three quarters of that increase, 77,2%, was achieved in the last five years. The indicator is currently on a trajectory of achieving the annual indicative values until 2030 set in the National Energy and Climate Plan from 2024 (NECP 2024).

Final energy consumption in buildings amounted to 1,475 ktoe in 2024 and was 2% above the annual indicative value, which was therefore not achieved. Compared to the previous year, it remained at approximately the same level, and compared to 2005, it decreased by 23%. Greenhouse gas GHG emissions in buildings amounted to 1,100 kt CO₂ eq in 2024, thus the annual indicative value was also not achieved.
