KOBiZE report<\/h1>\n\n\n\n
\"\"<\/figure>\n\n\n\n

The KOBiZE report is one of those environmental obligations that entrepreneurs most often downplay until the end of February approaches. In practice, many companies still erroneously assume that the report to the National Database only concerns large industrial plants. Meanwhile, the obligation may also cover small and medium-sized companies, if their activities cause emissions into the air. KOBiZE (the National Office for Environmental Protection) explicitly reminds that the report for 2025<\/strong> must be entered into the system by the end of February 2026.<\/strong>, and preparing the data in advance is intended to help the obligation to be submitted smoothly and on time. For the entrepreneur, the most important conclusion is simple: the obligation is not determined by the size of the company, but by whether its activities actually cause emissions.<\/p>\n\n\n\n

Who is most often subject to the reporting obligation?<\/strong><\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Most often, the KOBiZE report concerns entities using the environment whose activities result in emissions of gases or dust into the air. In practice, this will include companies operating gas, oil or solid fuel boilers, production plants, workshops, paint shops, warehouses, as well as some service companies with their own fuel combustion sources. The official KOBiZE handbook makes it clear that reporting not only covers large installations, but also, for example boilers and other stationary equipment generating heat for the plant's own use<\/strong>, emissions, such as heating of office buildings, halls or hot water. This is why many small companies are falling into the obligation, even though they did not previously identify their activities with environmental emissions.<\/p>\n\n\n\n

What is the step-by-step preparation of the report?<\/strong><\/h2>\n\n\n\n

The safest approach is to start not with the form itself, but with the source data. The company should first establish what emission sources were operating in 2025, what fuels were being consumed, what equipment was operating and whether the activity also included emission-causing processes. Only then should it access the National Base system and enter the report through the account created for the environmental entity. The official KOBiZE handbook indicates that all activities are performed electronically via the National Database website, and the new entity is also registered online after confirming its identity. In practice, this means that the report is not created \u201efrom memory\u201d, but from a combination of fuel documents, technical data and knowledge of the company's actual emission sources.<\/p>\n\n\n\n

What mistakes do companies make most often?<\/strong><\/h2>\n\n\n\n

The most common mistake is to omit small fuel combustion sources because the entrepreneur considers them too small to matter. Meanwhile, KOBiZE publishes separate material for boilers and other stationary technical equipment precisely because this is one of the most frequently overlooked areas of reporting. The second mistake is starting work on the report too late, so that the company does not have time to collect reliable data. The third problem is the failure to check whether an activity qualifies for a simplified report<\/strong>, which KOBiZE makes available to some entities. In practice, the best strategy is to determine the scope of the obligation in advance, choose the right reporting mode and calmly prepare the data before the end of February. This is when the KOBiZE report ceases to be a source of stress and becomes a structured element of environmental compliance.<\/p>\n\n\n\n

Frequently asked questions<\/strong><\/p>\n\n\n

\n
\n
\n

By when must a KOBiZE report be submitted?<\/strong><\/h3>\n
\n\n

Report to the national database for 2025<\/strong> must be introduced by the end of February 2026.<\/strong>.<\/p>\n\n<\/div>\n<\/div>\n

\n

Can a small company also have a KOBiZE obligation?<\/strong><\/h3>\n
\n\n

Yes. The obligation is determined by the emissions associated with the activity and not by the size of the company itself. This also applies to companies operating small boilers or other sources of fuel combustion.<\/p>\n\n<\/div>\n<\/div>\n

\n

Is the KOBiZE report submitted on paper?<\/strong><\/h3>\n
\n\n

No. The report is entered electronically through the subject's account in the National Base system.<\/p>\n\n<\/div>\n<\/div>\n

\n

Is a simplified report available for the KOBiZE?<\/strong><\/h3>\n
\n\n

Yes. KOBiZE provides a simplified version of the report and a separate guide to this reporting mode.<\/p>\n\n<\/div>\n<\/div>\n

\n

Can a company-owned boiler trigger a reporting obligation?<\/strong><\/h3>\n
\n\n

Yes. The official KOBiZE guidance explicitly covers boilers and other stationary technical equipment generating heat for the plant's own use.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n
