Scope 3 for Storytellers

Why does one number strike fear into so many otherwise confident businesses? Say the words “Scope 3” in a room of sustainability managers and watch the shoulders tense. It is the hardest emissions figure to pin down, the trickiest to reduce, and by far the most awkward to explain to anyone outside the room. And yet, if you want to talk honestly about your climate impact, it is often the number that matters most.

So let us try to make it human. Not because you need to become an accountant, but because if you are going to communicate about this at all, you should genuinely understand what you are saying. Here is Scope 3 explained in language a normal person can follow.

What are the three scopes?

The three scopes, quickly. Emissions get sorted into three buckets. Scope 1 is the stuff you burn directly. The gas in your boiler, the fuel in your own vans. It is yours, it is close, and it is relatively easy to measure.

Scope 2 is the energy you buy in, mostly electricity. You did not burn it on site, but it was generated for you, so it counts as yours in a slightly less direct way. Still fairly manageable.

Then there is Scope 3, and this is where it gets big. Scope 3 is everything else across your whole chain. The emissions from making the things you buy, from shipping your products, from your staff commuting, from customers actually using what you sell, and eventually from throwing it away. It is all the carbon connected to your business that you do not directly control.

Why Scope 3 is challenging

Why it is so hard. The reason Scope 3 is a headache is simple. Most of it happens outside your walls, in the hands of suppliers and customers you do not manage. You are trying to measure the carbon footprint of decisions made by other people, often several steps removed from you.

For a lot of organisations, Scope 3 is also by far the largest share of their total emissions. Sometimes the great majority. So you have this uncomfortable situation where the biggest part of your impact is also the part you can measure least precisely and control least directly. No wonder it makes people nervous.

How to tell the Scope 3 story

Telling the Scope 3 story well. Here is the thing, though. From a storytelling point of view, that difficulty is an opportunity, not a threat. Handled well, Scope 3 is where you get to show real honesty and real ambition.

Start by being upfront about the uncertainty. You will never have perfect Scope 3 figures, and pretending otherwise fools nobody who understands the subject. Saying “these are our best current estimates and we are improving them” is far stronger than false precision. It signals that you know what you are talking about.

Use a concrete example rather than a total. A giant number for your whole value chain means little to most readers. But “the biggest single part of our footprint is the materials we buy in, so that is where we are focusing” is something a person can picture and remember. One vivid piece of the chain beats an abstract grand total every time.

Show the direction, not just the position. People understand that you cannot fix a sprawling supply chain overnight. What they want to see is that you know where your Scope 3 impact sits and that you are moving on it. Progress and honesty are more convincing than a suspiciously tidy claim of perfection.

And resist the urge to hide it. The temptation with a big, messy number is to bury it in a footnote. But the businesses that talk openly about their Scope 3 challenge tend to earn more trust, not less, because they are clearly not cherry-picking the flattering figures.

The honest truth of Scope 3

The takeaway. Scope 3 is hard because it is honest. It counts the parts of your impact that are easy to ignore, and that is precisely why communicating it well says something good about you. You do not need to make it sound simple. You need to make it understandable, and you need to be straight about what you know and what you are still working out.

If you have wrestled your Scope 3 numbers into shape and now face the trickier job of explaining them to the outside world, that translation is exactly what we do. We would be glad to help.
