GHGs include: CO2, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride - the latter 3 are known
as fluorinated greenhouse gases.
But they haven't yet managed to create a surface that also repels the «wettest» fluids — those with very low surface tension, such

as covered entities.
If the Administrator determines, based on consideration of environmental effectiveness, cost effectiveness, administrative feasibility, extent of coverage of emissions, competitiveness and other relevant considerations consistent with the purposes of this title, that emissions of non-HFC
fluorinated gases can best be regulated by designating downstream emission sources
as covered entities with compliance obligations under section 722, the Administrator shall, after notice and comment rulemaking, change the definition of covered entity and the compliance obligations under section 722 with respect to non-HFC
fluorinated gases accordingly, consistent with the purposes of this title, and establish such other requirements
as are necessary to ensure compliance for such entities with the requirements of this title.
Companies in the industry have implemented a variety of emission reduction strategies, such
as optimizing (i.e., fine tuning) their production processes to use and emit fewer
fluorinated GHGs and switching to alternative input gases (for example, NF3), which are utilized more efficiently in the process, thereby emitting fewer
fluorinated GHGs into the exhaust stream.
