What you'll accomplish
The Scope 2 figure appears in the executive summary, again in a data table on page 40, and again in the appendix. The travel policy says one thing about flights and the report says another. Finding every mismatch by hand means a long afternoon with Ctrl+F. In Gemini Notebook (formerly NotebookLM) you load the report and policies as sources, then ask it to list every place a figure or phrase appears, quoted, so you can compare them in minutes.
Gemini Notebook finds candidates. You open each cited passage and decide what is actually inconsistent, and what to do about it.
What you'll need
What you should see: A folder of clearly named files. Troubleshooting: Gemini Notebook's help page says it supports PDF, Word, text, Markdown, Google Docs, Google Sheets (with a size limit), and web URLs. If a file will not import, convert it to PDF or paste the text.
What you should see: An empty notebook with a Sources panel on the left and a chat area. Troubleshooting: If the screen looks different from this description, search Google's Gemini Notebook help for "Create a notebook". The labels change.
Google's help page notes that sources imported from Drive sync with the original every few minutes, and that Notebook does not import footnotes or comments from Google files. Footnotes often hold the unit or boundary for a figure, so for any document with important footnotes, upload a PDF export of it instead.
What you should see: Each source in the Sources panel, with a summary available in the Source Guide. Troubleshooting: Check Google's source limits for your plan on the help page if the notebook refuses more files. Fewer, well-chosen documents work better than everything you own.
In the chat, select sources individually in the Source panel when you want a narrow check. When several sources are selected, name the document in your question so Gemini Notebook narrows its search.
Start with one figure at a time:
List every place the Scope 2 figure for 2025 appears across the sources. For each, give the document name, the page or section, and quote the sentence or table row exactly. Then tell me whether the figures, units and boundary descriptions match. If a source does not mention it, say so.
The Travel policy 2025 says what about air travel? The Report 2025 says what about business travel? Quote both. List any difference in wording, scope, or commitment between the two. Do not judge which is correct.
Open a spreadsheet with these columns: Item, Document, Page or section, Quoted text, Matches? (your decision), Action, Owner. Fill it from the citations after you have opened each passage.
What you should see: A list of citations you can click through to the source passage. Troubleshooting: If an answer has no citation, ask again with "cite the passage for every statement". Ignore any statement that still has none.
Find a phrase that should be consistent:
List every place the sources use the phrase "[phrase]" or a close variant. Quote each one with the document and page. Tell me where the wording differs.
Check a defined term:
How does each source define or describe "[term]"? Quote each. List differences.
Check a target statement across documents:
Quote every statement of a goal, target or commitment in the sources, with document and page. Group those that appear to refer to the same commitment and show where the wording differs.
Units check:
List every figure in the sources given in [unit]. Flag any place the same quantity appears in a different unit.
