May 2019, Paris

International Symposium
“Climate: Changing lifestyle and behaviors, a top priority, from citizen … to collective”.

This international conference took place on 28 May 2019 in the suits of the Paris City Hall (4th) and brought together scientists and climate experts, socio-economic actors, elected officials and institutional leaders, representatives of the academic world, students and weather presenters from some thirty countries.

To respect the objectives of the Paris Agreement, it is essential to build a collective reflection associating climate sciences and social sciences that will lead to the necessary change of behaviors to reduce our greenhouse gas emissions and adapt. This evolution must be undertaken not only by citizens but also by governments, communities and businesses, …. without excluding the education system and NGOs, which can play a key role.
