Carbon reporting: 4 mistakes to avoid when starting out
It's impossible to miss out on carbon reporting today: all the practices used to measure, track and publish an organization's greenhouse gas (GHG) emissions in a structured and regular way.
Unlike a simple one-off GHG assessment, this is an ongoing process designed to integrate carbon data into the company's strategy, in line with regulatory requirements (such as the CSRD) and climate commitments.
This reporting is based on recognized carbon accounting methods (ISO 14064, GHG Protocol, Ademe) and covers all emission scopes: direct, indirect and extended (Scope 1, 2, 3).
Driven by CSRD, CSR strategy and ESG criteria, more and more companies are committed to clearly defining their carbon reporting. But starting without a precise method can lead to dead ends. Here are the 4 main mistakes to avoid, so that your report is not just a stylistic exercise, but a strategic lever for reducing emissions.

Mistake 1: Confusing carbon reporting with a simple GHG balance sheet
Organizations often equate carbon reporting with a simple annual GHG balance sheet. However, producing a figure once a year is not enough. What is known as a BEGES (greenhouse gas emissions balance sheet) is in fact a snapshot of a company's GHG emissions. For it to be fully meaningful, this snapshot needs to be part of a monitoring dynamic, regularly updated, and linked to the company's strategy, so that it becomes a genuine basis for management.
Carbon reporting complements the GHG balance sheet: the latter is an essential first step, providing a snapshot of emissions at a given point in time. But
To ensure the sustainability of this approach, carbon reporting takes over. It enables structured monitoring, measuring changes over time and guiding operational decisions.
Where a balance sheet takes stock, reporting provides a dynamic for progress, a regular management tool adapted to the objectives and realities of the business sector.
C’est pour accompagner les entreprises au-delà du simple état des lieux que Decarbo’Solution® a conçu Decarbo’Solution®, une offre intégrée qui prolonge le BEGES par une démarche de pilotage opérationnel. Cette solution 3-en-1 associe :
- Decarbo'Target® to build a credible transition plan based on the existing balance sheet, simulate reduction trajectories and engage internal and external stakeholders;
- Decarbo'Supply® to mobilize suppliers via a portal for calculating the "carbon weight®" of their products or services (ISO 14067 / FEMPP ADEME compliant),
- Decarbo'Tender® to integrate these environmental data (PCF) into calls for tender, and guide purchasing decisions.
In other words: the BEGES provides an accurate picture of the company's carbon footprint; Decarbo'Solution® provides concrete, measurable levers for action.
How to sustain and strengthen your business through a successful low-carbon trajectory.
Error 2: Focusing solely on scopes 1 and 2
Another common pitfall is limiting ourselves to direct emissions linked to fixed installations or energy consumption (Scope 1 and 2). Yet it is in Scope 3 - in other words, indirect emissions linked to purchasing, transport, product use and digital technology - that the majority of a company's carbon footprint lies. In some sectors, this can represent between 70% and 90% of the total.
Réduire son périmètre d’analyse, c’est donc manquer de précision sur les sources d’émissions réelles, et passer à côté de leviers majeurs. Un avantage clé de Decarbo’Solution® réside dans l’accès gratuit qu’elle offre aux fournisseurs à son portail de calcul du poids carbone® de leurs produits ou services. L’engagement de ces derniers représente un véritable défi pour toute stratégie bas-carbone. La gratuité assure ici un engagement maximal : le Groupe Schmidt a ainsi réussi à enrôler 80 % de ses fournisseurs (en volume financier) dans sa démarche.
The Decarbo'Supply® tool has enabled us to track emissions very precisely, with cross-referencing by supplier, product and material. This granularity, combined with the
reporting, facilitated the development of a more visual, targeted and effective action plan. Suppliers, for their part, were able to visualize the carbon impact of their products in concrete terms - and understand precisely where it was coming from.
Utilisé intelligemment, Decarbo’Solution® est ainsi devenu pour Schmidt un outil d’aide à la décision, qui contribue à installer une culture carbone dans la durée.
Mistake 3: Not involving teams from the outset
Having the right method isn't enough. You also need to be able to collect all the necessary data. Relevant carbon reporting is never the work of a single person: it must be based on the mobilization of the entire organization and its employees.
Déléguer la démarche à un petit groupe, c’est risquer de passer à côté d’informations clés, mais aussi de priver l’entreprise d’une vraie dynamique collective. Chez Decarbo’Solution®, l’accompagnement est pensé pour faciliter l’implication interne. L’outil permet de nommer facilement des référents dans chaque service : production, achats, logistique, finance, ou encore numérique. Chacun sait ce qu’il doit fournir, peut solliciter le support à tout moment, et visualiser l’avancée grâce à des tableaux de bord partagés.
This dynamic makes data more reliable and turns carbon reporting into a real collective organizational project for the ecological transition. Everyone becomes aware of their impact, and reducing emissions becomes everyone's business - not just that of management or the CSR department. The process becomes more fluid, actions are better targeted, and the company progresses towards a more sustainable model, within a clear, shared framework.
Error 4: Forgetting to connect reporting and action plans
Good carbon reporting is only useful if it is used to trigger concrete action. It must become a real steering tool, aligned with greenhouse gas emission reduction objectives adapted to the company's activity. Once the roadmap has been defined, the next step is to ensure its operational implementation: which actions to start with, who to mobilize, what resources to allocate, and how to monitor progress?
C’est précisément là que le reporting carbone devient un allié stratégique. En structurant les données, en offrant une vision claire des postes les plus émissifs, il permet de traduire les engagements en actions concrètes et hiérarchisées. C’est pourquoi Decarbo’Solution® ne s’arrête
not GHG accounting: with the Decarbo'Solution® offer, our experts can help you move from an assessment to an action plan. Co-construct your climate roadmap, prioritize high-impact levers, and implement actions aligned with the reality of your sector and the expectations of your stakeholders, in France and abroad.
To meet the challenges of climate change, companies need to go beyond simple calculations: carbon reporting is becoming a lever for action in its own right, and all the more strategic in the age of CSRD. Integrating this approach into a structured CSR framework makes it possible to meet stakeholder expectations while controlling energy consumption. Carbon reporting bridges the gap between global challenges and operational realities, by translating regulatory requirements into concrete actions that are consistent with each company's activity.
En bref, se lancer dans un bilan carbone®, c’est un premier pas. Mais pour qu’il serve véritablement la transition durable, encore faut-il éviter les pièges classiques : limiter son périmètre, négliger l’engagement interne, dissocier reporting et pilotage. En vous appuyant sur une méthode éprouvée et un outil comme Decarbo’Solution®, vous donnez une véritable place au carbone dans votre stratégie d’entreprise — au service de la performance et de l’environnement. En structurant rigoureusement votre reporting carbone, vous maximisez l’impact de vos décisions et assurez un pilotage efficace de votre empreinte carbone.
