One of the most widespread renewable energy sources in Brazil is ethanol, from sugarcane, therefore, the sugar and alcohol sector is expanding, with positive impacts for the economy of the country. Sugar cane was introduced in Brazil as a crop during its colonization, for the production of sugar, and put the country in the global scenario. The expansion of this crop occurred in the seventies, to reduce the reliance in fossil energy sources and to stimulate the development of the agricultural activity. Thus, the federal government has promoted the sugar cane crop and the production of ethanol as a fuel. However, it is important to minimize possible impacts that the crop may cause to the environment. Sugar cane has expanded in the frontiers of the mesoregion of Triângulo Mineiro and Alto Paranaíba-MG, and, in this perspective, the agroindustrial complex known as Companhia Energética Vale do São Simão Ltda., with the Mill located in the county of Santa Vitória, Minas Gerais, was adopted to evaluate the environmental impacts caused by the sugarcane in the area of influence of the mill. The mill has a polygonal area corresponding to 53,525.20 hectares, and for its establishment a Study and Report of Environmental Impacts (EIA/RIMA) was presented, as required as an environment protection instrument by the Environment National Policy (Law nº 6.938/81), and detailed by the Resolution CONAMA nº 01/1986. These studies pointed that native vegetation fragments in the Area of Influence of the Mill, before its implantation, corresponded to approximately 20.7% of the area. Therefore, this study evaluated the impacts of the installation of Usina Vale do São Simão, between 2007 and 2012, determining its reflex on the environmental regularization of the farms, and the vegetation fragments existing in the area, in the recovery and recomposition of areas defined as Legal Reserve and Permanent Preservation. Previous studies of the area were analyzed, soil use and occupation was mapped for the years 2007 and 2012, and the areas of permanent preservation and native vegetation fragments were marked. In general, there was a decline in native vegetation coverage in the period, although it cannot be stated that such reduction was a direct effect of the milling activity. Therefore, the legal requirement of preserving such areas was not capable of bringing the positive effects of protection and recovery as demanded by the Law, highlighting that the current legislation was not enough to protect such areas.

The work is to demonstrate the scope of modern-day major regulatory provisions and the policies implemented to adoption of biofuels in the national energy matrix. The adoption of biofuels as an alternative to fossil fuels, is based on the realization of the fundamental right to an ecologically balanced environment mitigating hazards and environmental hazards arising from a postmodern society. However, the change in the Brazilian energy matrix observe the precepts of certain environmental principles to essentially environmental preservation The proposed Environmental rule of law is founded on the realization of the right (duty) key to an ecologically balanced environment for sustainable development. Thus, it is up to the State, in addition to considering the dangers and risks fruits of government decisions, present the possible instruments to mitigate the irreversible environmental damage to the environment. The management of environmental risks present in the ideals of an Environmental rule of law, plays an important role in the preservation and economic development, using, therefore, of acautelatórios legal instruments, such as environmental licensing and the ecological-economic zoning, measures adopted in the light of the principles of precaution and preservation. The adoption of research in the environmental field, improvement and development of environmental technology, building a system to observe ecological changes, imposition of environmental policy objectives to be achieved in the medium and long term and systematization of organizations plan a protection policy environmental, are essential measures to control possible environmental risks and damage guided by the aforementioned environmental principles. Thus, it will be used the inductive method of approach, starting from the analysis of the new perspective of Environmental rule of law and the implementation of biofuels in the context of a post-modern society, marked by uncertainty and the risk of damage, from the study of the principles of caution, maintaining and cautionary measures in mitigating the hazards and potential risks.
