Abstract
By how much and over what time-frame, should anthropogenic emissions of greenhouse gases be reduced to avert global climate change? Research to answer this question has been stronglypromoted within framework of Berlin Mandate. In recent year, two main, but rather different, approaches have been taken. They are:“Optimum Emission Trajectory” and the “Safe Emission Corridor”. From the view point of “Safe Emission Corridor”, this paper concludes the necessity of implementing major emission reduction policies before 2010. Also it strongly supports existing targets for developed countries to stabilize their emissions by the year 2000, make furtherreduction by 2010, and cooperate with developing countries to reduce their total emission thereafter.
