This study analyses the National Programme for Production and Use of Biodiesel launched by the Brazil Federal Government in 2005 as a public policy to generate sustainable employment and income within the context of development of new alternative sources of energy. It also verifies the impact of PNPB on occupation and income rate of farmers participating in the projects of production of biodiesel through field research carried out on 93 family farms participating in projects already implemented in the State of Goiás. The choice of producers was made at random from a list of all producers who had already gone through a complete cycle of production and stretched across 33 municipalities in the second half of 2007. The survey data was obtained through a closed-ended questionnaire which was designed to ascertain: 1) the increase of occupation and income regarding producers participating in the projects, 2) ways of including these farmers into the programme, 3) technical assistance offered to them (according to the guidelines of the programme) and 4) the evaluation of the programme by participating farmers. The SPSS software was used for processing and data analysis. The results show that most of the objectives of the programme, such as generation of occupation and income by family farming, are being achieved.
