During recent years, an increased attention has been given by industries and governments from industrialized as well as developing countries to reduce greenhouse gas (GHG) emissions through the clean development mechanism (CDM). As China has increasing demands on bioenergy and Sweden has good practices and competence in developing and utilizing bioenergy technologies, this paper studies the resulting consequence if implementing Swedish bioenergy technologies in China. The potential CO2 emission reduction from each technology in China is studied. A few priority areas for future CDM projects selection by using Swedish technologies are recommended.
