In May 2019, the Intergovernmental Panel on Climate Change (IPCC) adopted the 2019 Refinement of the 2006 IPCC Guidelines for National Greenhouse Gas Inventories. The 2006 IPCC Guidelines are currently used by many parties to the United Nations Framework Convention on Climate Change (UNFCCC) for preparation and reporting of their national greenhouse gas (GHG) inventories. The 2019 Refinement includes updates or new guidance for seven industrial processes that emit fluorinated greenhouse gases (GHGs). The guidance for electronics manufacturing was updated to include new guidance on tracking gas consumption and on apportioning gas consumption to different process types, updated and new Tier 2 methods that account for the size of manufactured wafers in semiconductor manufacturing, a new Tier 3b method for estimating emissions by developing facility-specific emission factors at the stack level, new guidance on adapting Tier 2 methods to account for technological changes, updated guidance on accounting for the use of emissions control equipment, new guidance for the sub-sector microelectromechanical systems (MEMS), and updates to the default emission factors for Tier 1 and Tier 2 methods, including an expanded list of input gases, by-products, and fluorinated liquids. This presentation will provide an overview of these updates.
