Joint Implementation (JI)

Joint Implementation (JI) refers to emission reduction projects that are carried out in developed countries or transition countries. The emission reduction certificates generated are tradable.  

Unlike the Clean Development Mechanism, Joint Implementation (JI) projects are carried out in other developed countries or in transition countries (with a reduction target) under the Kyoto Protocol (Article 6). Certificates from JI projects are called Emission Reduction Units (ERUs).

Emission reductions can be achieved by converting Assigned Amount Units (AAUs) from the host countries into ERUs, which are then transferred to the investing country. But the total emissions of the countries concerned do not change (unlike the CDM, it is a zero-sum operation, in which additional certificates are generated).

Switzerland does not host any JI projects. Therefore, it does not issue ERUs.

The Supervisory Committee oversees JI projects. Overall, the control procedures are less strict than for CDMs. Joint implementation projects should also result in the transfer of modern technologies to host countries.
