Sustainability rating schemes has come to be used extensively since it´s arrival to Sweden during the 21th century. Today, the number of sustainability certifications increases for projects in the construction industry while only a few projects has been certified in the civil engineering industry. The reasons of the interesting development has been studied by investigating how the construction industry clients in the public sector should be able to claim use of sustainability rating schemes without infracting the Swedish public procurement act.
The study has been conducted by literature- and interview research. Interviews were conducted with various stakeholders in the industry. The purpose was to obtain an unambiguous opinion of how clients should require use of sustainability rating schemes in public procurements. The study also discussed how stakeholders monitor and evaluate their work.

The overall conclusions from this study is:

• More pilot projects must be implemented to find out how to achieve maximum benefit with sustainability rating schemes.
• The industry wants more clear and measurable requirements.
• Not to be contrary to the Swedish public procurement act, clients can phrase functional requirements based on the manual of the sustainability rating scheme they wish to use.
• The clients should not worry about appeals, since appealed procurements because of sustainability requirements is rare. It is important to have clearly phrased requirements where the choice of sustainability rating scheme, specified criteria and level is clarified.
• By the new EU-directives comes an update of the Swedish procurement act, which will enforce in 2016 with the intention of making it easier to set requirements for sustainability rating schemes.
