Following the Grenelle Forum in 2007, a greater stress is laid on stakeholder involvement in the NBS (2011-20). There has been an effort to include stakeholders across various levels of government as well as civil society and the private sector, upstream in the formulation of the strategy and downstream through voluntary subscription and commitment to the NBS. All stakeholders (legal entities) are invited to subscribe to promote and publicise the NBS. Each subscriber is invited to make a commitment to action within 18 months and present an action plan which must involve significant, supplementary, measurable and scalable action.
