Green　finance　and　investment　in　renewable　energy　(RE)　sources　are　two　of　the　most　important　climate　change　strategies　that　might　have　a　long-term　impact.　Micro-　and　macro-level　data　from　2010　to　2021　in　China　used　to　gain　a　new　analysis　of　the　impact　of　green　finance,　inflationary　pressures,　and　geopolitical　risk　in　improving　sustainability.　Regression　estimation　methods　were　used　to　tackle　this　while　considering　direct　and　indirect　associations　between　the　parameter　estimates.　According　to　recent　research,　environmental　taxes,　such　as　those　on　carbon　emissions,　have　been　shown　to　have　a　large　and　favorable　effect　on　profitability　in　RES.　The　volatility　of　oil　prices　and　geopolitical　risk,　on　the　other　hand,　has　a　negative　influence　on　the　investment　pattern　for　sustainable　energy　sources　in　China.　The　research　also　shows　that　green　rules　have　a　significant　role　in　reducing　the　impact　of　green　finance　on　RE　production.　Green　companies　in　China　should　be　pushed　so　that　RE　investments　are　regarded　as　a　long-term　strategy,　according　to　the　conclusions　of　the　research.　The　study＇s　theoretically,　and　empirically　conclusions　have　supplied　policymakers　and　environmentalists　with　useful　information　for　developing　and　implementing　environmental　initiatives　with　long-term　financial　benefits.　©　2022　Elsevier　Ltd
