Screening and categorization of projects is one of the key requirements of the Social and Environmental Standards (SES). 

In this regard, the objectives of UNDP's Social and Environmental Screening Procedure (SESP) are to:

• Integrate the SES Programming Principles in order to maximize social and environmental opportunities and benefits and strengthen social and environmental sustainability; 

• Identify potential social and environmental risks and their significance; 

• Determine the project's risk category (Low, Moderate, Substantial, High); and, 

• Determine the level of social and environmental assessment and management required to address potential risks and impacts.
