Abstract
The strategic case for treating environmental, social, and governance (ESG) risks as credit relevant is now widely accepted, yet the operational mechanics of embedding these risks into everyday corporate lending remain poorly understood, particularly within emerging banking markets. This study examines how ESG considerations are incorporated across the corporate lending cycle of second tier banks in Kazakhstan and identifies where practical breakdowns occur. Using process mapping, gap analysis, and structured benchmarking against six international banks, and drawing on regulatory guidance, supervisory reports, and institutional disclosures as evidence, the analysis traces ESG integration through each stage, from origination and due diligence to credit assessment, transaction structuring, and post disbursement monitoring. The central finding is that Kazakhstan's implementation gap is operational rather than strategic: banks recognize ESG as financially material and have built governance structures to support it, yet sustainability signals weaken as they move deeper into the credit process. ESG shapes screening and due diligence and informs expert judgment, but it rarely reaches internal rating models, pricing, covenant design, or portfolio steering. Two interdependent constraints, methodological inconsistency and uneven borrower disclosure, explain much of this attenuation. International practice suggests that the appropriate remedy is not a parallel ESG framework but the strengthening of existing credit infrastructure. The paper contributes a stage specific diagnostic of ESG attenuation and a proportionate, phased integration framework calibrated to an emerging market banking sector, offering supervisors and lenders a pathway toward more consistent, forward looking credit underwriting.
