In this paper, six developing countries with possible domestic ETS are analysed: Brazil, China, India, Kazakhstan, Mexico, and South Korea. Brazil has set up a stock exchange for voluntary carbon units which may precede a domestic trading scheme. China has made concrete steps towards the creation of regional ETS in various cities and provinces. Newer announcements even envisage the creation of a national system by 2015. However, these plans are still in early stages, and differ widely in their institutional designs.
