What’s In a Name? Paris Agreement's Legal Form Explained in 7 Questions

The document clarifies that the outcome of the Paris climate talks will likely be a 'package' of instruments with varying legal forms, including a core legal agreement, UNFCCC decisions, and potential political declarations. It emphasizes that the legal force of the agreement is determined by its specific content and prescriptive language rather than its name (e.g., treaty, protocol, or accord). The text further explains that the agreement can contain a mix of binding and non-binding provisions and that the domestic ratification processes of participating countries will vary according to their own legal systems.

• The outcome of COP21 is expected to be a 'package' comprising multiple instruments of different legal forms, including a core legal agreement, decisions of the Conference of the Parties to the UNFCCC, and possible political declarations.
• The legal force of the Paris agreement is determined by its content and the use of precise, prescriptive language—such as obligations for policies, results, or procedures—rather than the specific name given to the document.
• International agreements, including the Paris outcome, can legally function as agreements even if they contain a combination of binding and non-binding provisions.
• Under international law, a treaty is broadly defined as a binding agreement between countries, though the United States has a stricter domestic definition requiring the 'advice and consent' of the U.S. Senate for certain subtypes of binding agreements.
• The process for joining the agreement is handled through individual domestic legal systems, with countries confirming completion by depositing an 'instrument of ratification, acceptance or approval.'
