It shows the Calculate CO2 action on sustainability journal lines, emission factor file uploads, calculation explanations, warnings and regeneration. Delivered as a public preview in the first release, English officially supported. [Watch on YouTube](https://www.youtube.com/watch?v=JBGuaqk5nXk) · Microsoft Dynamics 365 Business Central (YouTube) · 2025-04-01 · 17:24 · tier official · reviewed (checked by Opus) ## Overview The video explains how Copilot helps calculate emissions in the sustainability journal. Most emissions, such as hotel stays, do not come with ready totals. Copilot matches journal lines to emission factors from uploaded Excel files, or from public information when no file matches, and then calculates the total. The demo covers preparing factor files, reviewing matched factors and sources, reading the calculation explanation for each line, handling warnings about missing data, and editing a line description and regenerating. It closes with availability, language support and the roadmap. The presenter says the copilot is expected in 26.1 or 26.2 as a public preview, with general availability as a later goal. ## Key points - The Calculate CO2 action calculates total emissions, can update emission factors if configured, and adds source information for auditing. - Emission factors already in the system appear as automated suggestions without calling the LLM. Only missing factors are sent to the LLM. - Emission factor files are Excel files organized by columns. Cut them down to only the necessary information for performance, and mark obsolete files so they can be removed. - If uploaded files have no match, Copilot falls back to public information and shows the source as public information. - Line descriptions need to be specific, for example 'large motorbike' rather than 'motorbike'. You can edit the description on the suggestion page and click regenerate. - Each calculation has an explanation showing the formula and values used. Formulas differ by type, such as distance for cars, nights for hotels and calculated distance for flights. - In the first release it is a public preview with official support for English only, expected in 26.1 or 26.2. The presenter says other languages may still work. ## Chapters - [0:00](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=0s) Introduction and challenges with sustainability emissions - [2:24](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=144s) Copilot workflow and emission factor calculation process - [5:28](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=328s) Preparing and managing emission factor files - [8:42](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=522s) Demo with matched emission factors and sources - [11:17](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=677s) Calculation explanations and verification workflow - [13:26](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=806s) Handling warnings and improving descriptions with regeneration - [15:26](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=926s) Availability, language support and future roadmap ## Features | Feature | Status | At | Evidence | |---|---|---|---| | Calculate CO2 copilot action | preview, demoed | [1:26](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=86s) | "in this first release it will be delivered as a public preview as all our copilot features" ([15:47](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=947s)) | | Emission factor file uploads | preview, demoed | [6:07](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=367s) | "in this first release it will be delivered as a public preview as all our copilot features" ([15:47](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=947s)) | | Automated emission factor suggestions | preview, demoed | [3:15](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=195s) | "in this first release it will be delivered as a public preview as all our copilot features" ([15:47](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=947s)) | | Contextual warnings for missing data | preview, demoed | [4:00](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=240s) | "in this first release it will be delivered as a public preview as all our copilot features" ([15:47](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=947s)) | | Public information fallback | preview, demoed | [4:13](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=253s) | "in this first release it will be delivered as a public preview as all our copilot features" ([15:47](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=947s)) | | Description refinement and regeneration | preview, demoed | [14:12](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=852s) | "in this first release it will be delivered as a public preview as all our copilot features" ([15:47](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=947s)) | | Calculation explanation transparency | preview, demoed | [11:17](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=677s) | "in this first release it will be delivered as a public preview as all our copilot features" ([15:47](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=947s)) | | Flexible emission factor update settings | preview | [1:46](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=106s) | "in this first release it will be delivered as a public preview as all our copilot features" ([15:47](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=947s)) | ## Quotes - [0:54](https://www.youtube.com/watch?v=JBGuaqk5nXk&t=54s) "most emissions again do not have uh total amounts already ready.
