By 2020, the implementation of energy efficiency (EE) and renewable energy source (RES) measures in the public sector resulted in a cumulative energy savings of 228 GWh, and the cumulative CO₂ emissions reduction was 56 kt. The values of both indicators lagged behind the annual target values by 26% and 12%, respectively. The 2020 targets were thus not achieved, which is largely due to the insufficient intensity of investments in the period 2015–2017.

In 2020, CO₂ intensity in the commercial and institutional sector increased further compared to the previous year, to 33 t CO₂/million EUR1995, and lagged 0.7 percentage points behind the annual target value. The 2020 target was thus not achieved which is due to a 3.8% reduction in value added caused by the implementation of measures for preventing the spread of the SARS-CoV-2 virus. In comparison to 2010, the intensity was 55% lower.

In 2020, specific CO₂ emissions in the residential sector amounted to 9.2 kg CO₂ eq/m² or 3% more than the previous year and were 0.4 percentage points below the annual target,. The 2020 target was thus not achieved. The increase was mainly due to the increase of CO₂ emissions from the use of fuels in this sector by almost 4%. The increase was caused on one hand by the colder year, and on the other hand by the coronavirus pandemic and the implementation of measures for preventing the spread of the SARS-CoV-2 virus.
