Unlike Clean Development Mechanisms, Joint Implementation (JI) projects are carried out in other developed countries or in transition countries (Annex 1, with reduction targets) 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. As a result, the total emissions of the countries concerned do not change (it is a zero-sum operation, unlike the CDMs, where 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.
