Carbon optimization in Azure now includes new capabilities to improve visibility into cloud emissions data. Enhancements include expanded API limits, extended role-based access, and new filtering options for better analysis.
New API version with expanded limits: The latest API version (2025-04-01) removes the previous 5,000-item limit, allowing users to retrieve emissions data at scale for a more comprehensive analysis. Carbon Service - REST API
Subscription Reader role access: Users with Subscription Reader role now have default access to carbon optimization, enabling more stakeholders to view emissions data. Access overview
Emissions by Resource type: Emissions reporting now categorizes data by resource type (e.g., Virtual Machines, Azure Data Explorer) instead of by service, providing deeper insights for optimization. View and analyze emission data and insights
New resource type and location filters: Users can now filter emissions data by resource type and location, making it easier to focus on specific areas for sustainability improvements. View and analyze emission data and insights
These enhancements are available in carbon optimization through the Azure portal and API.
