Developed enhanced carbon emissions reporting for AWS Billing Data Export within the awslabs/cid-framework repository, focusing on detailed Scope 1, 2, and 3 metrics. Leveraged CloudFormation and data engineering skills to update the aggregation YAML, introducing new fields and refining the default query and schema for improved ESG reporting accuracy. The work centered on precise data modeling and YAML configuration, enabling more granular sustainability metrics and supporting future extensibility. By committing these changes, the developer addressed the need for comprehensive carbon tracking, ensuring that exported billing data now includes units and values for each emissions scope, thereby increasing data completeness.
