Carbon Reporting: 4 Mistakes to Avoid When You're Just Starting Out
It’s impossible to ignore carbon reporting today: it refers to the set of practices used to measure, track, and report an organization’s greenhouse gas (GHG) emissions in a structured and regular manner.
Unlike a one-time GHG assessment, this is an ongoing process aimed at integrating carbon data into the company’s strategy, in line with regulatory requirements (such as the CSRD) and climate commitments.
This report is based on recognized carbon accounting methods (ISO 14064, GHG Protocol, Ademe) and covers all emission scopes: direct, indirect, and extended (Scopes 1, 2, and 3).
Driven by the CSRD, CSR strategies, and ESG criteria, more and more companies are committing to a clear definition of their carbon reporting. But starting without a specific method can lead to dead ends. Here are the four main mistakes to avoid so that your carbon footprint assessment isn’t just a stylistic exercise, but a strategic tool for reducing emissions.

Mistake 1: Confusing carbon reporting with a simple GHG inventory
Organizations often equate carbon reporting with a simple annual GHG inventory. However, producing a figure once a year is not enough. What is known as a GHG inventory is, in reality, a snapshot of a company’s GHG emissions at a given point in time. To be truly meaningful, this snapshot must be part of an ongoing monitoring process, regularly updated, and aligned with the company’s strategy so that it can serve as a solid foundation for decision-making.
Carbon reporting complements GHG accounting: the latter is an essential first step—a snapshot of emissions at a given point in time. But
To ensure this approach is sustainable over the long term, carbon reporting takes over. It enables the establishment of a structured monitoring system, the measurement of changes over time, and the guidance of operational decisions.
While financial statements provide a snapshot of the current situation, reporting fosters a culture of progress and serves as a tool for ongoing management, tailored to the objectives and realities of the industry.
Decarbo’Solution® developed Decarbo’Solution® to support companies beyond a simple assessment—an integrated offering that extends the BEGES framework with an operational management approach. This 3-in-1 solution combines:
· Decarbo’Target® to develop a credible transition plan based on the current baseline, simulate reduction trajectories, and engage both internal and external stakeholders;
· Decarbo’Supply® to engage suppliers through a portal that calculates the “carbon footprint®” of their products or services (compliant with ISO 14067 / ADEME),
· Decarbo’Tender® to incorporate this environmental data (PCF) into requests for proposals and guide purchasing decisions.
In other words: BEGES provides an accurate picture of a company’s carbon footprint; Decarbo’Solution® helps identify concrete and measurable actions based on that information.
How to ensure the long-term viability and growth of your business through a successful low-carbon strategy.
Mistake 2: Focusing solely on Scopes 1 and 2
Another common pitfall is limiting the analysis to direct emissions related to fixed facilities or energy consumption (Scopes 1 and 2). However, it is in Scope 3—that is, indirect emissions related to procurement, transportation, product use, and digital activities—that the majority of a company’s carbon footprint lies. In some sectors, this can account for between 70 and 90 percent of the total.
Narrowing the scope of analysis therefore leads to a lack of precision regarding actual emission sources and overlooks major levers for action. A key advantage of Decarbo’Solution® is the free access it offers suppliers to its portal for calculating the carbon footprint® of their products or services. Securing their commitment represents a real challenge for any low-carbon strategy. Offering the service for free ensures maximum engagement: the Schmidt Group has thus succeeded in enrolling 80% of its suppliers (by financial volume) in its initiative.
The Decarbo’Supply® tool has enabled highly accurate tracking of emissions, with cross-referencing by supplier, product, and material. This level of detail, combined with the system’s
The Group’s reporting made it easier to develop a more visual, targeted, and effective action plan. Suppliers, for their part, were able to see the carbon footprint of their products in concrete terms—and understand exactly where it came from.
Used wisely, Decarbo’Solution® has thus become a decision-making tool for Schmidt, helping to foster a long-term carbon-conscious culture.
Mistake 3: Not involving the teams from the start
Having the right method isn’t enough. You also need to be able to collect all the necessary data. Effective carbon reporting is never the work of a single person: it requires the involvement of the entire organization and its employees.
Delegating the process to a small group risks overlooking key information, but it also deprives the company of a true collective dynamic. At Decarbo’Solution®, our support is designed to facilitate internal engagement. The tool makes it easy to appoint points of contact in each department: production, procurement, logistics, finance, or IT. Everyone knows what they need to provide, can request support at any time, and can track progress through shared dashboards.
This approach ensures the reliability of the data and turns carbon reporting into a genuine collective effort toward the ecological transition. As a result, everyone becomes aware of their own impact, and reducing emissions becomes everyone’s responsibility—not just that of senior management or the CSR department. The process becomes more streamlined, actions are better targeted, and the company moves toward a more sustainable model within a clear and shared framework.
Mistake 4: Failing to Link Reporting and the Action Plan
Effective carbon reporting is only useful if it leads to concrete action. It must become a genuine management tool, aligned with greenhouse gas emission reduction targets tailored to the company’s business. Once the roadmap is defined, it must still be implemented operationally: which actions should be prioritized, who should be involved, what resources should be allocated, and how should progress be tracked?
This is precisely where carbon reporting becomes a strategic ally. By organizing the data and providing a clear picture of the areas with the highest emissions, it makes it possible to translate commitments into concrete, prioritized actions. That is why Decarbo’Solution® doesn’t stop
More than just GHG accounting: with the Decarbo’Solution® offering, our experts help you move from assessment to action plan. Work with us to develop your climate roadmap, prioritize high-impact levers, and implement actions aligned with the realities of your industry and the expectations of your stakeholders, both in France and internationally.
To address climate challenges, companies must go beyond mere calculations: carbon reporting is becoming a driver of action in its own right—one that is all the more strategic in the era of the CSRD. Integrating this approach into a structured CSR framework allows companies to meet stakeholder expectations while managing their energy consumption. Carbon reporting thus bridges the gap between global challenges and operational realities by translating regulatory requirements into concrete actions that are consistent with each company’s business activities.
In short, undertaking a carbon footprint assessment® is a first step. But for it to truly support the transition to sustainability, you must avoid common pitfalls: limiting its scope, neglecting internal commitment, and separating reporting from management. By relying on a proven methodology and a tool like Decarbo’Solution®, you give carbon a meaningful role in your business strategy—in the service of both performance and the environment. By rigorously structuring your carbon reporting, you maximize the impact of your decisions and ensure effective management of your carbon footprint.
