Resource-based　companies　are　key　players　in　reducing　carbon　emissions　and　play　a　central　role　in　achieving　China＇s　dual-carbon　goal.　Establishing　and　improving　an　objective　carbon　information　disclosure　mechanism　for　companies　and　evaluating　the　quality　of　carbon　information　disclosure　in　a　scientific　and　reasonable　manner　have　significant　reference　value　for　rationally　shaping　the　way　to　realize　carbon　peak　and　carbon　neutrality.　In　view　of　this,　this　paper　develops　an　evaluation　index　system　based　on　four　dimensions　based　on　the　corporate　social　responsibility　reports　of　listed　companies　from　2018　to　2022.　After　excluding　firms　with　a　high　degree　of　greenwashing,　the　combined　weighting-TOPSIS　method　was　used　to　evaluate　the　carbon　disclosure　quality　of　companies.　The　research　results　show　that,　although　the　quality　of　carbon　disclosure　of　resource-based　companies　has　indeed　improved　since　the　2020　dual-carbon　goal　was　proposed,　there　are　differences　in　the　quality　of　carbon　disclosure　of　companies　between　different　subsectors　and　regions,　and　relevant　policy　recommendations　are　proposed.
