Cemig included in Brazil’s new Carbon Efficiency Index

Cemig (Companhia Energética de Minas Gerais), a listed company with securities traded on the stock exchanges of São Paulo, New York and Madrid, as part of its commitment to best corporate governance practices, hereby informs its stockholders and the market in general as follows:

Cemig has been included in the Brazilian ICO2 Carbon Efficiency Index.

This new stock index, created by the São Paulo stock, Commodities and Futures Exchange (BM&FBovespa), is an indicator to Brazilian and international capital markets of the commitment and alignment that Brazil and its listed companies have in relation to the most up-to-date positions and debate on climate change.

The ICO2 index is made up of the shares of those companies that are in the portfolio of the IBrX-50 index and have subscribed to this initiative, weighted by the greenhouse gas emissions of each of the companies.

Cemig has increased its participation in the IbrX-50 index from 1.196% to 2.275%; and its participation in the portfolio of the ICO2 index, for this year of 2010-2011, is 53.8% of the total of all electricity sector shares that are included in the ICO2.

Cemig’s very significant position in the ICO2 index reflects its commitment to taking action to minimize greenhouse gas emissions — highlighting its generation of electricity from renewable sources.
