Galvanizing the Groundswell of Climate Actions welcomes the opportunity to share our views on opportunities to further enhance the effective engagement of non-Party stakeholders. The wide spectrum of non-Party stakeholders play a number of important roles in the UNFCCC process and addressing climate change more broadly. Encouraging effective participation by non-Party stakeholders will support implementation of the Paris Agreement. This submission has two sections. The first is a brief overview of the importance of non-Party stakeholder engagement. The second looks at specific opportunities for enhanced engagement to strengthen the implementation of the provisions of decision 1/CP.21.
