Joint Implementation

The concept of Joint Implementation (JI ) or English Joint Implementation ( JI) called any of the decisions provided for in the Kyoto Protocol's flexible mechanisms for the reduction of pollutant emissions.

If a State is listed in Annex B of the Kyoto Protocol, it may acquire through implementation of pollution control measures in another Annex B country additional emission rights for its domestic producers of pollutants.

The resulting emission reductions due to such foreign commitments is solely credited to the investor country. The basic idea is that it is secondary, where an emission is reduced. The decisive factor is that it is broken down.

The Joint Implementation thus allows a transfer of reduction certificates ( emission reduction units, ERUs ) from an Annex B country to another. The total amount of all Annex B countries are entitled emissions is not increased by the Joint Implementation.

Often created by the Joint Implementation is a win -win situation. The investor country will have the right to be allowed to make additional emissions. Due to increasing marginal costs of emission reductions, an investment in emission reduction measures in the host country here is often cheaper than a reduction of emissions in their own country. The host country, however, earns the sale of emission rights and is also benefiting from technology transfer from the investor country.

Invests in a country listed in Annex B emission reduction measure in a country which is not listed in this Annex, it additional emission rights under the Clean Development Mechanism are allocated.
