From 2018 to 2020, the IWF is co-organized by a new partnership governance composed of Météo et Climat, EcoAct and IWC2.


I look forward to seeing you at the 16th edition of the IWF, to be held from May 25 to 28, 2019 on the Place of Paris City Hall.
This edition will focus on the necessary evolution of the behaviors at a large scale: citizens but also governments, communities, companies, …. including the education system and NGOs that can play an important role in the dynamics of these changes.
I hope to see you soon to act for climate in everyday life.

Jean Jouzel, President of Météo et Climat, climatologist and former member of the IPCC Bureau (Organization co-Nobel Peace Prize in 2007).

The important thing today is to create a link between various publics, from the citizen to the collective, for a greater mobilization against climate issues!
In the context of reducing emissions and adapting to climate change, it is necessary that we ALL change our behaviors. For the first time, this theme will be common to the FIM 2019 General Public and Professional programs. On this occasion, the weather presenters from all over the world will affirm their role as “Climate Communicators” and will share their actions.

Christian Vannier, founder and director of the IWF, president of IW2C.

In order to act quickly and effectively, we need all the stakeholders -the involved actors- to be gathered and mobilized! This is why we wanted to create a participatory operation, a kind of coalition gathering the different communities committed to the IWF’s missions and French/international reputation. Experts, scientists, weather reporters, associations/NGOs, decision-makers and CEOs are getting involved together to work along with citizens and to act for climate… for a better everyday life!

Sylvianne Villaudière, General Coordinator of the IWF, vice-president of EcoAct.
