{"abstract":"The EPA is announcing to the public the availability of estimated global warming potentials, as well as data and analysis submitted in support of them, for eight fluorinated heat transfer fluids. We are requesting comments on the estimated global warming potentials and the data and analysis supporting them. We are also requesting comment on the cited global warming potentials for 35 other fluorinated greenhouse gases and fluorinated heat transfer fluids for which we do not currently possess supporting data and analysis. The EPA is requesting comment on the global warming potentials of all 43 chemicals as we consider adding these global warming potentials to the Greenhouse Gas Reporting rule.","action":"Notice of data availability and request for comment.","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2013/04/05/2013-07977.html","cfr_references":[],"citation":"78 FR 20632","comment_url":null,"comments_close_on":"2013-05-06","correction_of":null,"corrections":[],"dates":"Comments must be received on or before May 6, 2013.","disposition_notes":null,"docket_ids":["EPA-HQ-OAR-2009-0927","FRL-9799-4"],"dockets":[],"document_number":"2013-07977","effective_on":null,"end_page":20637,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2013/04/05/2013-07977.xml","html_url":"https://www.federalregister.gov/documents/2013/04/05/2013-07977/mandatory-reporting-of-greenhouse-gases-notice-of-data-availability-regarding-global-warming","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2013-07977?publication_date=2013-04-05","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2013-04-05/2013-07977/mods.xml","not_received_for_publication":null,"page_length":6,"page_views":{"count":3099,"last_updated":"2026-04-17 22:15:06 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2013-04-05/pdf/2013-07977.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2013-07977.pdf?1365080300","publication_date":"2013-04-05","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2013/04/05/2013-07977.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Summary of Data Collected to Support Determination of Public Availability of Inputs to Emission Equations for which Reporting was Deferred to March 31, 2015","document_id":"EPA-HQ-OAR-2009-0927-0338"},{"title":"Summary of Public Comments and Responses for Greenhouse Gas Reporting Rule: Revisions to Reporting and Recordkeeping Requirements, and Proposed Confidentiality Determinations Under the Greenhouse Gas Reporting Program","document_id":"EPA-HQ-OAR-2009-0927-0337"},{"title":"Memo from L.
