The CESBA initiative policy paper establishes the policy position of CESBA regarding EU policy developments on sustainable building. The incentive to draw up the paper has been a process launched by the European Commission within the frame of the Europe2020 strategy: The Commission aims at developing a Europe-wide approach to assess the environmental performance of buildings. The CESBA initiative policy paper welcomes this process and highlights the need for a harmonized approach due to the diversity of local issues in Europe. CESBA stresses that it is ready and willing to share its knowledge with all stakeholders.
