The process of steel production emits a large quantity of greenhouse gases, specifically carbon dioxide (CO2), and the reduction of such emissions is one of the main challenges for the industry in the 21st. Century. To quantify these emissions, the Worldsteel Association (association of the 170 large steel manufacturers of the world) published a methodology (CO2 Emission Data Collection) for calculation and comparison of CO2 emissions among its members. After that, in 2010, this methodology became an ISO (International Organization for Standardization) norm. Today, the calculation of the CO2 emissions in steel making companies follow the ISO 14404-1 for units with blast furnaces and the ISO 14404-2 for units with electric furnaces. In the last years, new technologies were and continue to be developed for the steel making sector aiming at energetic improvements and greenhouse gas reductions (mainly CO2) by the several processes involved in the production of steel. This work had the objective of producing a tool to calculate the CO2 emissions for the steel making sector. An Excel spreadsheet was developed to calculate the emission intensities of CO2 of a steel plant, the Usina Presidente Vargas, of the Companhia Siderúrgica Nacional (CSN). The spreadsheet furnishes results of CO2 emissions and energetic fluxes, and simulates the benefits that some of the new technologies can give to the company. The spreadsheet calculates the emissions in two ways: a) based on the carbon fluxes that enter the unit, and b) based on the emissions of each specific process within the unit (coking, sinterization, blast furnace, among others)

The importance of the capital market to Brazilian economic development, linked to the the fragility of a theoretical framework on the issue, case for developing this research. The agents operating in the capital market seek security and confidence for decision making on their investment in that sense we seek to address the concept and values of Corporate Governance to pay in the Brazilian capital market. The Corporate Governance, in its essence, is the system by which companies are directed and monitored, involving the relationship between shareholders and the board of companies, as well as a set of mechanisms and factors intended to minimize market failures. Seeking to confirm adherence to a more advanced system of corporate governance can result in a favorable financial performance, companies were investigated operating in the financial sector (intermediation, various services and insurance), listed by BM&FBOVESPA. The stock market ranks the corporate governance systems in three levels: Level 1 (rudimentary), Level 2 (intermediate) and New Market Level (advanced). To earn the impact of different levels of Corporate Governance for the outcome of the selected companies were calculated and analyzed accounting ratios of profitability, capital structure and liquidity from the Standardized Financial Statements (DFP), base year 2011, 2012 and 2013
