Global warming and climate change are realities clearly established by scientists. It is mainly due to greenhouse gas emissions related to human activities. One of the main sources of greenhouse gas emissions is transportation. Thus, the first part of this Erasmus+ project will consist of an analysis of the problem. We'll do some statistics of the temperature and rainfall in the different countries over many years. We'll do experiments about greenhouse effect and measure greenhouse gas emissions. We'll also make the pupils understand how to compensate these emissions.
