This study analyses the climate implications of deep renovation and energy supply decarbonisation in Estonia. The study estimates the greenhouse gas mitigation potential of renovating the entire Estonian residential building stock by 2050, as outlined in the national long-term renovation strategy.

The findings of this study indicate that the complete implementation of decarbonisation strategies could reduce annual greenhouse gas emissions from the existing residential stock by up to 95% compared to 2020. The embodied emissions from the renovation measures are minor compared to the energy savings gained. In the Estonian context, the overall success of building decarbonisation is closely tied to the carbon intensity of grid electricity. If the current fuel mix in electricity and district heating production persists, comprehensive renovation may paradoxically result in higher emissions than the baseline.
