The resource constraints and other political barriers are the reasons for this delay. Therefore, the proposed energy efficiency laws and by-laws are fully in accordance with the EU requirements, due to the fact that development of the energy efficiency sector is mainly driven by fulfilment of the obligation that Bosnia and Herzegovina undertakes by ratification and signing of various international treaties such as Energy Community Treaty and Energy Charter Treaty. Both on the state and entity levels a lot of activities were done in order to develop energy efficiency framework that will promote EE, raise awareness in this area and attract foreign and domestic investors to invest in EE projects.
