Community reduction

from Wikipedia, the free encyclopedia

The term community reduction (GR) or English Joint Implementation (JI) describes one of the flexible mechanisms for reducing pollutant emissions provided for in the Kyoto Protocol .

If a country is listed in Annex B of the Kyoto Protocol, it can acquire additional emission rights for its domestic pollutant producers by implementing emission-reducing measures in another Annex B country.

The resulting reduction in emissions due to such a foreign commitment is credited to the investor country alone. The basic idea here is that it is of secondary importance where an emission is reduced. The only thing that matters is that it is dismantled.

The Joint Implementation therefore enables emission reduction units (ERU ) to be transferred from one Annex B country to another. The total amount of emissions to which all Annex B countries are entitled will not be increased by the joint implementation.

The joint implementation often creates a win-win situation . The investor country receives the right to issue additional issues. Due to increasing marginal costs in the area of ​​pollutant reduction, an investment in emission-reducing measures in the host country is often cheaper than reducing emissions in your own country. The host country, on the other hand, earns from the sale of emission rights and also benefits from the technology transfer from the investor country.

If a country listed in Annex B invests in emission-reducing measures in a country that is not listed in this Annex, it will be allocated additional emission rights according to the Clean Development Mechanism .
