To improve user experience and streamline carbon emissions calculations in Microsoft Sustainability Manager, we propose organizing Calculation Models and Calculation Profiles by categories or emissions sources. This enhancement will make it significantly easier for users to locate the appropriate calculations they need for specific scenarios. By categorizing and grouping calculations based on emissions sources, industries, or other relevant criteria, users can quickly identify the right calculation for their sustainability assessments, saving time and effort.

Moreover, we could introduce a "Favorites" feature, allowing users to mark and save frequently used calculations for quick access. With this feature, users could easily bookmark the calculations they rely on most, reducing the need to search for them repeatedly. This personalized organization would further optimize workflow efficiency and empower users to work with their preferred calculations effortlessly.
