Reducing carbon emissions in a core system
UBM and Microsoft shift computational tasks in CO2-reduced times
This whitepaper discusses the first enterprise-scale implementation of carbon-aware computing, a collaboration between UBS and Microsoft under the Green Software Foundation (GSF) umbrella. Using the GSF Software Carbon Intensity (SCI) specification and carbon-aware-sdk tooling, the partners implemented a time-shifting strategy for UBS's risk platform, running workloads during periods of lower carbon intensity in the grid. This approach is projected to prevent multiple metric tons of CO2eq from entering the atmosphere annually.

Foundational basic Patterns
Combine small activities into composite activities
Let workers perform as many steps as possible for single cases
If capacity is insufficient, consider increasing the available number of resources
Move activities to more appropriate places
Offer a green alternative with the same outcome, utilizing different steps, resources, or partners, while retaining the previous existing process
Performance-based task assignment
Allocate tasks based on past performance: execution time and success
Allocate task based on past feedback or quality metrics
Allocate task based on collaborative experience: handover time, interactions, diversity
Distribute tasks by interdepartmental interactions to enable or restrict involvement
