Mr. Seán Armstrong:

The way it would work and the way it works in other member states is by introduction on a declaration basis. This is the way it has happened in Denmark and some other member states. Initially, public sector buildings declare their embodied carbon performance. Then there will be some capacity building. It would possibly be required for public sector projects. Eventually, performance requirements would be introduced that buildings would have to achieve. One has to have the methodology and a project database and build the capacity in the system. Designers need to know how to use these tools. All manufacturers must have certificates for their products. That capacity has to be developed through voluntary certificates and procurement processes and then through regulatory disclosures and regulatory performance requirements.
