The rules of Level One largely undertake to improve methods of disclosure to the market and to disperse their shares among the largest number of shareholders possible. Thus, the main practices required to join are: (i) maintenance of a free-float of at least 25 percent of the capital; (ii) public offerings have to use mechanisms to favor capital dispersion; (iii) improvement in quarterly reports, including the disclosure of consolidated financial statements and special audit revision; (iv) monthly disclosure of trades involving equities issued by the company on the part of the controlling shareholders;  and (v) disclosure of an annual calendar of corporate events.

Sustainability
CESP, aware of its responsibility to sustainability, has sought to align itself with the effort to contribute to the advancement of sustainable practices and has incorporated into its work schedule activities in tune with this subject. To undertake sustainable actions that contribute ultimately to the effort to assure the right to a life in harmony with nature for present and future generations, CESP has developed several environmental projects. Preservation actions are implemented in partnership with the scientific community in order to promote the exchange of information with agencies and research institutes in Brazil and abroad.

After the release of the second inventory of greenhouse gases in June 2009, recording the emission of 9,700 tonnes of carbon equivalent (tCO2) for the year of 2008, it was created a plan with a goal to reduce by 10 percent the greenhouse gases emissions of the year 2011 in comparison with 2008 emissions. The company also studies the inclusion of activities in the carbon market through the approval of clean development mechanism projects (CDM) of the Kyoto treaty and/or voluntary market.
