Sovereign debt investors typically applyexclusionary screeningas a primary ESG approach. Unlike corporate bond investors, sovereign debt investors have limited direct engagement opportunities with governments. Therefore, they often use exclusionary screening to filter out countries with poor ESG performance, such as those involved in human rights violations, corruption, or weak environmental policies.

For example, many sustainable bond funds exclude investments in countries with poor governance indicators (e.g., high corruption, low press freedom) or those that fail to meet international environmental agreements such as the Paris Agreement.
