Aside from a sudden drop in the early 1990s, emissions from the buildings sector have continued to steadily decrease, with emissions in 2019 56% lower than 1990 levels. 1.5°C pathways require a drop both in emissions and emissions intensity, with direct CO₂ emissions needing to fall by 12-38% below 2019 levels by 2030.
Electricity’s share of final energy in the buildings sector should increase from 27% in 2019 to 40-48% by 2030 and rise to 61-69% by 2050. Depending on which pathway is followed, the sector could decarbonise as early as 2038, or as late as 2050.
Czechia’s decarbonisation goals require a phasing out of gas and coal boilers, with heating being switched to low-emission sources such as heat pumps. This needs to be combined with improved energy efficiency through retrofitting poorly insulated buildings. Residential buildings account for 77% of emissions in the buildings sector, and the Czech government has set a target of renovating 1.4% of residential buildings annually (an annual target of 1.4% has also been applied to non-residential buildings).
