The presentation was perfectly prepared. I had spent weeks building the most complete inventory I had done to date: Scope 1, Scope 2, and Scope 3 subcategories, in accordance with the GHG Protocol Corporate Value Chain Standard. It was a company with a strong national presence that had decided to take environmental transparency seriously.
When I projected the slide with the total results, silence filled the room. The executive, who until then had shown satisfaction, frowned when he saw the Scope 3 block.
—“This can’t be right,” he said. “Are we responsible for all of this? How are we going to mitigate such a huge amount of emissions?”
I tried to explain that these emissions are reported to understand the total impact of the value chain, not because the company must take on all of them directly. But the confusion had already set in. In that moment I understood a key truth: technically correct data can trigger rejection if it is not communicated strategically.

Why does Scope 3 generate so much impact… and so much fear?
In many companies, especially in manufacturing, technology, consumer goods, or energy, the most significant emissions do not originate in their own operations, but across the entire value chain. In other words, Scope 3 dominates the total emissions inventory, representing between 70% and 95% of the carbon footprint (GHG Protocol, 2024; Envoria, 2023). For this very reason, understanding and correctly communicating Scope 3 is critical.
A study from the GHG Protocol Scope 3 Calculation Guidance notes that in industries with extended supply chains, these indirect emissions can be up to five times higher than direct ones. This means that a logistics company reporting only 1,000 tons of CO₂e across Scope 1 and 2 could be hiding up to 5,000 tCO₂e or more in Scope 3, mainly from supplier activities, outsourced transportation, or inputs.
For example, in the energy sector the data is even more compelling: the International Energy Agency (IEA) documents that more than 80% of the emissions linked to the sector come from the end use of fuels sold to consumers, which corresponds entirely to Scope 3. In fact, according to estimates from the Carbon Disclosure Project (CDP), 75% of global corporate emissions come from Scope 3, although in industries such as financial services or industrial manufacturing that percentage can approach 95%.
Why report it if you can’t directly control it?
The answer to this question lies in the concept of relevance. The GHG Protocol states that emissions should be reported when they are relevant to understanding the impact, risks, and opportunities of the company. It is not about having operational control over all of them, but about having the capacity to influence, decide, or gain visibility.
Thus, Scope 3 not only reveals the problem: it also opens up the map of possible solutions. It allows you to identify where the most effective levers for change are: in the purchase of inputs, product redesign, supplier selection, logistics, or even in how your products are used.
The company is not “guilty” of those emissions, but it is a co-creator of the system that generates them.
Let’s go back to the beginning: as we always say, it is essential to understand it in order to facilitate the conversation with teams. It is useful to recall how emissions are organized according to the GHG Protocol:

How is Scope 3 structured?
The GHG Protocol divides Scope 3 into 15 categories, which cover the entire value chain, grouped into two large blocks: upstream (inputs, services, logistics) and downstream (products sold, use, end-of-life disposal).
The goal is not to take on the entire burden, but to map the points where you can intervene with the greatest impact.
Lessons for communicating Scope 3 better
After facing many reactions like that executive’s, I have learned some keys to avoid rejection and turn data into decisions:
1. Start with context, not figures
Opening with an absolute number (like “100,000 tons”) can block the conversation. Begin by explaining the type of emissions that Scope 3 includes: suppliers, transportation, use, product end-of-life. This way you prepare the ground for understanding.
2. Make it clear that reporting does not mean offsetting everything
Many believe that if you report it, you have to mitigate it. That is not the case. Reporting is knowing. Then, you can decide where to act: influence, change, or manage directly.
3. Rank the emissions
Not all categories carry the same weight. Classifying them by hierarchy allows you to focus the conversation and prioritize.
-
Critical (>10%)
-
Relevant (1–10%)
-
Minor (<1%)
4. Translate technical language
You don’t need to eliminate the terms, but you do need to translate them. “Upstream emissions” can be explained as “the impact of our suppliers.” And so on with every technical concept that might sound abstract.
5. Close with a path to action
Don’t leave your audience alone in front of a sea of data. Offer a roadmap: What can you change today? Where do you need allies? Which indicators are the most important?

Scope 3 as a strategic compass
Once the team understood that Scope 3 was not a threat, but a compass, the conversation changed completely:
—“Now I see it with different eyes,” the director told me. “This isn’t just an inventory; it’s a vision tool.”
And that is exactly what it is: a guide for redesigning value chains, strengthening relationships with suppliers, and anticipating climate change risks. That is why thousands of companies are already doing it. More than 1,100 companies with targets validated by the Science-Based Targets initiative have completed Scope 3 inventories. Not because they are required to, but because it is the best way to make informed decisions.
