Stewardship (Option A) is a core regulatory theme in ESG investing, focusing on how investors influence corporate behavior through active ownership (voting, engagement, and dialogue). Regulatory frameworks such as the UK Stewardship Code, Japan Stewardship Code, and EU Sustainable Finance Disclosure Regulation (SFDR) emphasize investor stewardship responsibilities.

Scenario analysis (Option B) is used for risk assessment, particularly in climate stress testing (e.g., TCFD recommendations), but is not the primary focus of ESG regulations.

Green bond issuance (Option C) is regulated under ICMA Green Bond Principles and EU Green Bond Standards, but ESG investing regulations are broader than just bond issuance.
