A new summit dedicated to concrete action

A global summit, Climate Chance aims to become a regular event for all non-state actors involved in the fight against climate change..

The initiators

" The COP21 was a success and a major step in the commitment by States to fight against climate change. It is a global challenge that calls for local action. Major cities, towns and all civil society carry solutions for concrete, ambitious and real action.
A global summit, Climate Chance aims to become a regular event for all non-state actors involved in the fight against climate change.

Local authorities, associations, trade unions, scientific organisations and citizens are invited to this meeting, which should enable a picture to be drawn of the state of action worldwide, exchanges to take place to explore in depth the successes and difficulties, to promote the pooling of experience and innovations, and to highlight the opportunities that arise from this resolute fight against climate change.

Welcomed at the initiative of Nantes, the first edition of Climate Chance will take place from 26 to 28 September at La Cité, the Nantes Congress Centre. This major event should bring together several thousand participants from all over the world.

European Green Capital in 2013, President of Eurocities, the network of 130 major European metropolitan areas, climate spokesman for the Cités et Gouvenement locaux unis (CGLU) network, Nantes is a recognised city for the ecology and energy transition. Building on the Nantes urban area, this world summit will enable actors to experiment concrete dialogue between local civil society and representatives of international civil society.

Lastly, following the World Summit on Climate & Territories in Lyon last year, and a few weeks before the Habitat III summit in Quito, and the COP22 in Marrakesh, this summit will be the chance to deliver new common messages from non-state actors, without which we will be unable to stabilise global warming."

The Climate Chance summit

On a number of occasions, 2015 shone the spotlight on the strength of the commitment made by non-state actors in the fight against climate change.


As the year drew to a close, the Paris Agreement secured at the COP21 provided a solid platform to mobilise the international community and the full spectrum of actors. This agreement, unprecedented in scale, places work by non-state actors at the forefront of climate solutions, and bolsters efforts to encourage their involvement to meet the targets for the 2015-2020 period. It also paves the way for all these actors to play a role in re-evaluating the contribution made by nation states by 2018.


Growing influence for non-state actors.


The determination of non-state actors to contribute to the effort is a reality, and their mobilisation represents a formidable potential for greenhouse gas reduction. Regional strategies and the involvement of the business world and civil society are how efforts to attenuate climate change and adapt really gain traction. The quality of this involvement relies on their ability to work together, to cooperate and pool their talents, strategies and resources by developing synergies between different groups of actors. It has become increasingly clear since the Paris Agreement, that the Action Agenda is the road map to securing their involvement.


Who are the non-state actors?
