This project has been created as a subproject of an Erasmus+ project . It’s a partnership of secondary schools from 6 countries: Spain, Hungary, Czech Republic, Portugal, Italy and Belgium. The project is divided into 6 paths: 1. Analysis of the problem of climate change and its anthropic relationship (based on scientific evidence) in a general and introductory way. 2. The energy sector, 3. Pollution and waste mismanagement, 4. The mass production of food to satisfy unhealthy nutritional needs. 5. The loss of biodiversity on the planet. 6. "Sustainable cities and communities" Each path consists of two sections: • A 1st section in which the problems of the sector are identified and how it affects us locally and globally. • The 2nd section is called “Students in action!” KEYWORDS: Climate change – sustainable development – green skills
