Carbon　peaking　and　carbon　neutrality　are　gaining　global　consensus,　and　carbon　reduction　in　aviation　is　necessary　and　urgent.　The　main　objective　of　this　research　paper　is　to　map　and　analyze　the　knowledge　graph　of　aviation　carbon　emissions　research　from　a　bibliometric　perspective.　Publications　related　to　aviation　carbon　emissions　indexed　by　Scopus　for　the　period　1992　to　2021　were　analyzed　primarily　using　CiteSpace　software.　This　paper　presents　a　bibliometric　analysis　of　current　research　progress　from　four　perspectives:　(1)　descriptive　analysis　of　publications,　involving　annual　distribution,　authors,　and　journals;　(2)　analysis　of　co-cited　authors　and　their　countries;　(3)　co-citation　analysis　of　cited　references;　and　(4)　co-occurrence　analysis　of　keywords.　A　series　of　domain　knowledge　maps　were　constructed　to　visualize　the　core　of　aviation　carbon　emissions　research　and　to　distill　the　research　perspectives　on　aviation　carbon　emissions　in　the　past　20　years.　The　latest　and　most　important　research　results　in　the　field　obtained　through　the　combing　provide　certain　references　for　the　research　and　development　of　aviation　carbon　emissions.
