Therefore,whiletheconsolidationandharmonisationofthenumerousvoluntaryframeworks,standardsandguidance,suchusTaskForceonClimate-RelatedFinancialDisclosures(TCFD),theSustainabilityAccountingStandardsBoard(SASB),theGlobalReportingInitiative(GRI)andtheInternationalIntegratedReportingFramework(<IR>Framework),intoafewmandatoryandpotentiallymandatoryregulationsisapositivestep,thereiscontinuedsignificantdivergenceinreportingstandardsthatwillpotentiallyhaveanimpactonassurance.
