This dissertation aims to analyze and compare the determinants of environmental innovations generated by Brazilian companies, according to sectoral patterns of technological change, using data from the National Innovation Survey (Pintec) published by the National Institute of Geography and Statistics (IBGE). The research can be considered descriptive and applied. The methodology included bibliographical research on innovation, sectoral patterns of technical change; technological classifications and low carbon corporate strategies, highlighting the importance of environmental innovations for achieving their targets; the contribution of previous empirical studies on the determinants of environmental innovations; documentary research concerning the CNAE Classification and the Pintec 2014, both published by IBGE; content analysis to classify the economic activities of respondent companies of Pintec 2014, according to the sectoral patterns of technological change, as proposed by Pavitt; elaboration of a tabular plan aligned to the research questions for requesting data to IBGE; data collection; application of the logit econometric model to analyze and compare the determinants of environmental innovations by sectoral pattern; interpretation and discussion of results. The use of indicators from Pintec 2014 to analyze and compare the determinants of this type of innovation and the association of these indicators with the sectoral patterns proposed by Pavitt give the research an innovative character, since previous studies on environmental innovation did not explore this methodological approach. At the governmental level, the results generated (by sectoral pattern of technical change) will be relevant for the formulation of more consistent and well-structured public policies concerning environmental innovation.
