More and more the corporations are being charged for Environmental Sustainability performance, especially in developed markets and this indicator is essential for reaching the global warning control targets .Today Brazil has a significant share of the global food trade and has a leading hole taking into consideration the alert for climate changes and food security issues that are becoming relevant due to global population growth. Bringing even more focus on this subject, the country has one of the largest biodiversity of the planet and holds the greatest share of the Amazon, the largest rainforest in the world and responsible for part of the global climate balance, while the agroindustry is responsible for the consumption of more than 70 percent of Brazilian water resources, occupies around 21 percent of the national territory and accounts for 74 percent of the country s greenhouse gas emissions. In this context, rooted in Resource Based- View and Institutional Theory, a model was constructed for the purpose of analyzing the impact of organizational factors (dynamic capacities) and the institutional environment (society, regulation, and competition) on environmental sustainability strategies and how these strategies impact export performance of Brazilian agricultural companies. In the literature there are few empirical studies focused on analyzing the relationships between these constructs and none of them within the scope of the Brazilian agroindustry, besides that, an additional contribution was sought when analyzing how the level of maturity in environmental sustainability of the countries influences the relation between the sustainability strategies and export performance. For the model s test, a data survey was conducted with managers of 143 exporting companies from the Brazilian agroindustry, through an online questionnaire and the Structural Equation Modeling (PLS-SEM) was used to estimate parameters. The empirical results corroborate some of the hypotheses presented, revealing the significance of the main relationship of the study (sustainability strategies and export performance) and distinguishes between the organizational factors and the external environment that most impact on the adoption of these strategies, besides to present the leadership engagement in the sustainability as the main internal factor of the adoption of this type of strategy, as well as the perceived pressure of foreign society and competition as the main external factors. However, the main theoretical contribution of the study is derived from the analysis of the moderation factor. The results show that the relationship between environmental sustainability strategies and export performance was more significant in the group of companies that export to countries with a greater maturity in the area of environmental sustainability, than in the group of companies that export to least mature countries in this theme.
