The outcome of COP21 clearly recognised the efforts of all non-party stakeholders, including civil society to address and respond to climate change. The EESC has advocated for civil society and citizens at global, national and subnational levels to be fully involved in the development, review and, above all, implementation of the COP21 Agreement. This opinion will be an opportunity to address the issue of climate governance in the context of implementation of the Paris Agreement and to identify the mechanisms and measures for civil society to be involved.
