Which AWS service or feature should the company use to meet this requirement?

Explanations:

AWS Organizations is used for managing multiple AWS accounts in a single organization and does not directly provide environmental impact reports related to AWS usage.

IAM policy is used to manage access permissions for AWS resources and services. It does not provide reports or insights regarding environmental impacts of AWS usage.

The AWS Billing console includes tools and reports that can help users estimate the costs associated with their AWS services, and it also provides insights into the usage of services, which can be correlated to environmental impact assessments.

Amazon Simple Notification Service (SNS) is primarily a messaging service that allows sending notifications and does not provide any reports or insights on environmental impacts of AWS usage.
