May 2019, Paris

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

This international Symposium will be held on May 28, 2019 in the Paris City Hall (4th) and will bring together scientists and climate experts, socio-economic actors, elected officials and institutional leaders, representatives of the academic community, students and media.

Changing lifestyle and behaviors… a collective challenge

The Paris Agreement calls for reducing global warming to less than 2°C above versus the pre-industrial levels, if possible 1.5 ° C. However, the commitments agreed by all the Parties lead us towards a trajectory of temperature rise higher than 3 ° C by 2100. This will generate an increase of climate extremes, heat waves, hurricanes submerging habitat and population, raising of the sea level … and many other consequences.
To respect the objectives of this Agreement, it is imperative to build a collective reflection combining climate sciences and social sciences that will lead to the necessary change of behaviors to reduce our greenhouse gas emissions and adapt.
