International cooperation to support climate change mitigation and sustainable development
This paper analyses the flexible instruments Joint Implementation (JI) and Clean Development Mechanism (CDM) with regard to achieving CO2 emission reduction targets in a sustainable way. In a first step, an optimising energy and material flow model is used to elaborate emission reduction strategies for Germany. The same methodology is then applied to Indonesia in order to determine the emission baseline for this country, which is an indispensable requirement for the evaluation of project-based flexible instruments. Then, models for Germany, Russia and Indonesia are linked using a decomposition algorithm with the aim to elaborate emission reduction strategies for Germany, including JI and CDM projects. The results show substantial potential to limit emission reduction costs by multilateral cooperation. The most favourable types of cooperation project for the considered countries are CO2 sequestration and power plant projects. Finally, an approach to how to include the criterion of sustainable development is described.
