The Union Registry is an application that can be used with a standard web browser (such as Firefox, Internet Explorer or Chrome). It does not have to be downloaded and installed on your computer. It is an electronic directory in which the ownership of emission certificates is registered in accounts. For this purpose, emission certificates of different types can be transferred between accounts in the registry. It consists of two main sections, an EU ETS section and a Kyoto section. The emission certificates exist only in electronic form. The registry is explicitly a no-trading platform thus supply and demand are not traded here.
On the following pages you will find information about opening and managing an account, security and background information on the Union Registry and the different types of certificates.
