Recital 16

(16)A number of Member States have public procurement policies in place which require contracting authorities to procure energy efficient products. A number of Member States also have put in place incentives for energy efficient products. The criteria for products to be eligible for public procurement or incentives can substantially differ from one Member State to another. To refer to performance classes as levels for particular products, as set out in delegated acts under this Directive, may reduce fragmentation of public procurement and incentives and facilitate the uptake of efficient products.
