ELI has been a market leader in the production of foreign language materials for over 30 years. Its supplementary material, class magazines, as well as language courses and complementary publications for Kindergarten, Elementary and Secondary Schools, and University, have created a world famous brand and a name that guarantees quality and reliability. This is an important ethical choice and means that we make an investment not only in terms of the quality of our books for those that choose and use our books, but also in terms of the environment that surrounds all of us. This is a small gesture that has a strong significance for us. The FSC brand certifies that the origin of the paper used for the production of our books is controlled at source and that the forests used are not destroyed but managed carefully.
