The EU is considering increasing the GHG emissions reduction target by 2020 from 20% to 30% by committing each member state to tighten up its emission reduction goals. According to the recent study such decision could cost some 2 365 million LTL to Lithuanian economy. Evaluation and comparison of CO₂ abatement costs incurred by the state implementing a variety of measures in different sectors allow choosing a most cost effective policy scenario. The paper focuses on CO₂ emissions related to energy use in buildings. First, this paper reviews the role of the Lithuanian building stock in overall GHG emissions. Then the paper examines the existing studies on the CO₂ mitigation potential and cost in buildings. Given the limitations of existing evaluation and lack of comprehensive modelling in the existing studies, this paper proposes a framework for examining the technology options aimed to inform policy making on the options to reduce CO₂ emissions in Lithuanian housing and service sectors.
