When the question gets harder
You need more than a number in a report.
A customer or lender wants emissions data. Your team needs to know what it can support with evidence.
A reporting requirement reaches across entities and sites. Your team needs a consistent process and clear ownership.
A reduction target needs an investment plan. The options have not been compared on economics or operating feasibility.
