["Corporate Social Responsibility and Environmental Management, EarlyView. ", "\nABSTRACT\nHigh‐quality environmental disclosure is becoming a global baseline as jurisdictions align with International Sustainability Standards Board standards. Prior literature provides mixed evidence on whether regulatory pressure promotes environmental transparency or induces symbolic greenwashing. To address this ambiguity, we examine corporate environmental disclosure strategies in the context of China's Environmental Target Responsibility system, a target‐based governance regime that combines disciplinary pressure with promotional incentives for local officials. Using a Large Language Model (LLM)‐based Specific Environmental Disclosure Index (SEDI), we assess whether stronger city‐level environmental targets induce firms to provide more specific and verifiable disclosure. We find that higher targets are significantly associated with higher SEDI, particularly among key polluters, politically weaker firms, and those facing tighter financing constraints. The underlying mechanism is that firms use specific disclosure to maintain environmental legitimacy and gain access to government‐controlled resources. Overall, the study demonstrates how regulatory constraints and incentives jointly shape corporate disclosure strategy and highlights an information‐channel consequence of a target‐based governance regime.\n"]
