This guide presents recommendations for Green Public Procurement (GPP) criteria to be applied on a voluntary basis in order to reduce the carbon footprint of building projects implemented by means of public funds under the Act on Public Procurement and Concession Contracts. Particular focus is placed on lifecycle thinking, which should be applied starting from the planning stage of buildings with calculations of the building lifecycle carbon footprint.

Besides the suitability requirements for tenderers and cost estimates, the criteria include the assessment of energy, material and innovation aspects. Specific criteria relating to these categories have been drawn up for the procurement of design services, procurement of materials and equipment, procurement of building works, Design & Build projects and Design, Build & Operate contracts. The criteria are supplemented by detailed instructions based on standards which enable the environmental assessors involved in the projects to make comparable calculations
