If someone asks you to measure your property’s scope 3 emissions, you should tell them that it’s basically impossible. Because it is. That’s the gist of this post. But before we despair over the endless range of scope 3 emissions for a hotel property, let’s toss in the GHG Protocol’s definition:
Scope 3: Other indirect emissions, such as the extraction and production of purchased materials and fuels, transport-related activities in vehicles not owned or controlled by the reporting entity, electricity-related activities (e.g. T&D losses) not covered in Scope 2, outsourced activities, waste disposal, etc.

How far does your supply chain reach? The vast scope, depth, and complexity of hotels' supply chains and customer interactions make scope 3 measurement a daunting task.
