CarbonFix: An Easy-to-Understand and Reliable Tool for Calculating Corporate Carbon Footprints
Understanding a company’s carbon footprint is becoming essential—not only for those striving to act responsibly, but also for businesses that want to remain part of global supply chains. The CarbonFix tool helps companies quickly and clearly identify the sources of their emissions and start managing them effectively.

More and more companies are facing demands for transparency in sustainability, whether from business partners, investors, banks, or the public. The carbon footprint is not just a number. It serves as a key input for an effective environmental strategy, a foundation for ESG reporting, and often a requirement for participation in international supply chains.
For companies that want to truly understand their carbon footprint but lack the capacity for complex calculations or in-house experts, our online tool CarbonFix is here. CarbonFix was developed as a response to the practical needs of companies and offers a clear, accurate calculation that is both professionally sound and accessible to those who are new to emissions data.
A Clear Calculation Based on Recognized Methodologies
At the core of CarbonFix is the globally recognized GHG Protocol. The results are divided into three Scopes, so companies know exactly where their emissions are coming from – whether from their own operations, energy consumption, or activities in their surroundings. The calculation is done online, and the user interface is designed to be intuitive even for someone who has never used similar tools before. However, at CI3, we are always ready to provide expert assistance and walk through the calculation together – because only when the client truly understands the results can they effectively work with them moving forward.
Companies can choose the level of calculation according to their needs, from a basic overview to a detailed report that includes graphs, recalculations, and interpretation of results. For paid versions, the calculations are also professionally reviewed by the CI3 team, and companies can receive a certificate as part of the SledujemeCO2.cz project, which is overseen by the Ministry of the Environment and the Ministry of Industry and Trade.

Verified Quality and the Opportunity to Try It Out
CarbonFix is one of the few tools on the Czech market that has been independently verified according to the ISO 14064-3 standard. This verification confirms that the calculation adheres to the international GHG Protocol standard. We are also happy to assist companies in preparing for the verification of their own calculations, where the quality and completeness of input data are most often assessed. The significance of this step is also reflected in the growing interest – the tool is now used by both Czech and international companies.
If a company wants to first get an idea of how the calculation works, they can use the demo version of CarbonFix for free. The demo shows how the tool's interface looks, what data needs to be prepared, and what kind of output the user can expect in the full version. The demo is especially helpful for companies that are encountering carbon footprint calculations for the first time but need to quickly understand the entire process.
A Tool That Evolves Alongside the Needs of Companies
CarbonFix is not a static system. It is continuously expanding with new features. We are currently working on simplifying the collection of data regarding employee commuting – as part of the calculation, an easily shared questionnaire will be available, allowing employees to fill it out for their trips. At the same time, we are making adjustments to facilitate easier calculations for large companies that need to break down their carbon footprint by individual branches.
It also connects to other CI3 services in the area of climate strategies, so companies that want to go beyond data collection can directly follow up with specific steps to reduce emissions.
A carbon footprint will not get smaller by ignoring it. The first step in reducing a company's environmental impact is understanding its current state. CarbonFix offers a way to quickly, clearly, and confidently get this number. Whether you need data for internal decision-making, for your partners, or for ESG reporting, CarbonFix enables better control over your emissions.
