Climate policies are orchestrated globally through the Conference of the Parties (COP) on climate (Copenhagen 2009, Durban 2011, Paris 2015). In Paris in 2015, the stakes were high: to negotiate a future binding international and universal agreement on the climate for the post-2020 period.The European Union has made commitments, notably in the context of the Europe 2020 Strategy and has adopted the Energy Climate Package (Common Energy Policy and the fight against climate change).The CLIMALL project is part of this dynamic and participates in popularizing these issues for a European awareness. The framework is of course on a smaller scale and has been conceived on the following premise: Europe's citizens have a leading role to play in the fight against climate change and the reduction of greenhouse gas emissions. greenhouse. To enable them to act, they must be brought to know and understand these issues; and especially the younger generations, citizens and European actors of tomorrow.The four youth organizations working on themes of sustainable development are based in territories more or less peripheral, rural, mountainous ... often more visibly impacted by the effects of climate change.

It is undoubtedly one of the first concrete projects of European cooperation formalized between professionals of the animation (formal and informal), of the formation or the education to the environment between 4 European countries. The realization of complementary educational tools on the issues, effects and means of action is a first concretisation of a strategic partnership for European youth which allowed to valorize local experiences and practices of mitigation or adaptation to climate change .Our desire is to put this project in a long-term perspective, hence the emphasis on its evolutionary dimension. It is also a question of disseminating the results (educational kit, participatory digital space in free access and open to all, serious game) and to accompany the dynamisation by the partners and the actors on the ground, through our actions of dissemination.The overall objective of CLIMALL is to participate in the European awareness of climate change. Beyond essential elements of knowledge and understanding, it helps young people to realize their role as eco-citizens, actors in their territory and decision-makers in the Europe of tomorrow ...
