The CDM program encourages countries that possess effective technology for reducing greenhouse gas emissions to assist other countries (generally developing countries) in developing clean industries, through such means as funding and technology transfers. The reduced emissions that result are credited to the donor country and count toward its own greenhouse gas reduction targets, or may be traded. Thus both donor and recipient benefit.
方案中鼓勵具備高效能減放溫室氣體排量技術的國家，透過資金及技術轉移等方式，去協助另一個國家（通常是開發中國家）發展潔能事業，因此減少的溫室氣體排放量則列入其「減量積分」中，是個利人利己的事。
