The European School of Positive Impact and Responsibility (ESPOIR)

European School of Positive Impact and Responsibility (ESPOIR) is an original summer school of PSL dedicated to Sustainable Development Goals (SDGs). 
ESPOIR has received the support of the Erasmus+ Jean Monnet Programme.
The 2022 edition will occur in Paris from July 18 to 23.
The call for applications is open until May 6, 2022.


ESPOIR aims to expose motivated students to state-of-the-art learning and innovative activities to gain a better understanding of Sustainable Development issues and EU engagement; the summer school aims to help students design effective solutions to 21st century challenges. 
The summer school will offer a comprehensive training, entirely taught in English, in contact with high-level scientists.
The participants will be 25 selected students coming from different backgrounds. Participation does not require previous EU knowledge or experience; only a sincere curiosity about the SDGs. 


Access to safe drinking water and sanitation is recognized by the United Nations as a fundamental human right. It is one of the goals of sustainable development. The 2022 edition will be focused on SDG 6 (water and sanitation) and will address the following issues: Technical, environmental and political issues related to water.

The main causes of pollution of lakes, rivers and oceans will be presented (bacteria, micropollutants, endocrine disruptors, microplastics). The methods of water analysis and the current and future methods of water treatment will be discussed. These technical parts will be completed by a visit to a waste water treatment plant. A part of the week will also be dedicated to water policies in France and in the world.
The students will benefit from both interdisciplinary teaching combined with hands-on innovation workshops and policy dialogues. The summer school will be based on different teaching formats (conferences, visits etc.), all of which promote interactivity and the sharing of ideas.

Detailed forecast program

The summer school will take place in Central Paris, at the Pierre-Gilles de Gennes Institute, 6 rue Jean Calvin - 75005 Paris.

    ESPOIR Summer School objectives: 

    • To deliver knowledge on EU issues to students not usually exposed to these matters. 
    • To empower students coming from all backgrounds to become enlightened citizens and leaders of the coming European Green revolution 
    • To develop innovative and experimental pedagogy and have an emblematic recurring international event. 
      Our ambition is that students position themselves in key roles  in the coming “Decade of Action” for the SDGs as promoters of sustainable development. We believe that students are called to build a sustainable Europe in line with the stakes of the Green Deal and the SDGs.
