"Joint Implementation" is the methodology to reduce the Greenhouse Gas (GHG) emission as stipulated in the United Nations Framework Convention on Climate Change (Note-below). When the Parties jointly implement the management measures to reduce GHG emission, it enables the distribution of the credits (the volume of GHG reduction) among the relevant Parties.

The Joint Implementation is extremely effective in reducing and limiting the global GHG emission inclusive of the developing country Parties, mainly in the fields listed below:

(1) The cost-effective reduction of GHG emission
(2) The promotion of environmental technology transfer

At the first session of the Conference of the Parties (COP1) held in March and April of last year, it was resolved to establish a pilot phase for "Activities Implemented Jointly (AIJ)" which would be open to the participation of developing country Parties on a voluntary basis.

(Note)

The United Nations Framework Convention on Climate Change was adopted at the Rio Summit (UNCED: United Nations Conference on Environment and Development) held in June, 1992, for the purpose of stabilizing atmospheric concentration of greenhouse gas. The Convention calls for the principles of (1) common but differentiated responsibilities of the Parties, (2) consideration to the national situation of developing country Parties and others, and (3) immediate and effective implementation of preventive policies and measures, and enacts the obligations, mainly to the developed country Parties, to implement preventive policies and measures for reducing and limiting the greenhouse gas.
