This background document seeks to support the Senegal Workshop on the Implementation of Biodiversity and Chemicals and Waste Multilateral Environmental Agreements (MEAs). The document has two substantive sections. First, it will highlight options and opportunities for action identified in the past in the field of cooperation and synergies in the implementation of MEAs at the national level (section II). Second, it will provide an introduction to the Kunming-Montreal Global Biodiversity Framework and the Global Framework on Chemicals—For a Planet Free of Harm from Chemicals and Waste and outline preliminary consideration of key entry points for mutually supportive action in the context of the implementation of both frameworks (section III). The annexes comprise a table illustrating the cross-mapping of MEA goals and targets with the Global Biodiversity Framework (Annex I) and a table illustrating key areas and targets of the Global Biodiversity Framework where chemicals and waste management can significantly contribute to implementation.
