Setting the Stage for Climate Action Under the Montreal Protocol

This evaluation identifies the 12 papers that formed the scientific foundation for the Montreal Protocol parties to take bold steps to phase down HFCs via the Kigali Amendment. These thoroughly researched and clearly presented scientific papers, which were among those contributing to SAP presentations at Meetings of the Parties and were directly read and considered by treaty negotiators from party countries, made the link between HFCs and climate change apparent and persuaded skeptics and stakeholders to take action. All told, the coauthors of these dozen papers include about 40 scientists from 10 countries, reflecting the substantial degree of international attention to the problems posed by HFCs and scientific collaboration to address them.
