    The changes introduced by the current Forest Code (Law no 12.651/12) caused manydiscussions between the Brazilian society. The law imposes rules that will reduce the widthsof the marginal strips of Permanent Preservation Areas (PPAs) in areas under consolidateduse, and therefore the environmental protection function is in doubt. Thus, the present studyaims to quantify the PPAs, estimate and value the same carbon stocks before the impositionsof the current Forest Code. The study was conducted in three catchments of the Bandeirante-PR municipality and the methodology employed made use of geotechnology, orbital image,geographic information systems (GIS), carbon stocks data arranged in the literature andcarbon market values. The results confirm that three of the four maps produced have PPAsvalues lower than required in the old Forest Code (Law no 4.771/65). The current situation ofPPAs is present in similar numbers with the requirements in the 2012 Code, but withfragmented and discontinuous forests. The recovery model obtained the PPAs values closer tothe model of the old law. As for the carbon stocks of the PPAs, the current situation isMg.C.ano-17.944 (worth US$ 215.743) and the recovery model is 13.970 Mg.C.ano-1(worthUS$379.397). In a time analysis, the annual growth rate was 132 Mg.C (value US$ 3.584).We conclude that the current Forest Code reduces the areas for PPAs over the old code. Manyproperties of the study area will amnesty in the current legislation. After the forest recovery ofAPPs, carbon stocks in the PPAs can generate payments for environmental services tolandowners.
