Key words: business, ecology, emails, sustainability, modern technologies. This project will aim at business correspondence among companies that want to be ecological and help the environment. The companies will create their logos catalogues and web pages and start doing business with each other as well as communicate about other matters, important for a sustainable development and environmental protection. The key to success in the modern world is the use of technologies, so we will try to include different types of communicative means and applications. The students will also practice their English language skills and learn new vocabulary and formal language.
