Introduction Petrobras is a company committed to Sustainable Development. When it interacts with the environment and uses its natural resources, the company is aware that it should render accounts to society on the impact of its operations on the biosphere, and contribute towards a better quality of life for the population. Accordingly, the company has enormous socio-environmental responsibility and invests in programs that not only defend environmental preservation but also encourage the development of ecological awareness within the communities. Over the past three years, Petrobras has invested around R$ 5.2 billion in the environmental security of its facilities and more than R$ 18 million in projects with environmental sponsorship, such as the Tamar, Humpback Whale and Manatee projects, for example. With its fiftieth anniversary in October 2003, the company launched the Programa Petrobras Ambiental. The Program, with projects chosen through a public selection process, considers investing R$ 40 million for the first two years. Water, understood as both fresh and saltwater bodies and their biodiversity, was chosen as the theme for Petrobras Environmental Program’s first public selection edition.
