Environmental damage caused by economic and institutional activities are a recurring concern in debates on the subject. Innovation has a key role so that countries may react against environmental challenges and, at the same time, enhance opportunities for new stimuli. The aim of this article is identify scientific and technologic specific areas that foster the environmental technologic development during the 1990s, 2000s and 2010s, in the countries that constitute BRICS and G7 groups. To achieve this aim, the methodological application involves the construction of Matrices of Interaction through the environmental patents. The objective of using this technique is to identify which science and technology foster environmental technology development. Futhermore, the representation of the matrices in graphics allow differentiate characteristics of mature and immature National Systems of Innovation. The results shows the influence of treaties and international environmental protocols that contributed to increase the production of environmental technologies, especially after the year 1990. Furthermore, developing countries, such as China, have similarities between the scientific and technological asymmetries as well as developed countries.
