The article presents a comprehensive assessment of the innovativeness of a manufacturing enterprise from the metal industry company, using an original method of diagnosing the state of innovativeness of enterprises. This method allowed for a comprehensive assessment of the level of innovativeness and eco-innovativeness of the enterprise, identification of sources of environmental impacts - product, production process, determination of the environmental profile of the enterprise, as well as assessment of the technologies used by the enterprise in terms of the TRL classification. The study showed that the enterprise has an average level of innovativeness, focuses primarily on the implementation of implementation works using technologies obtained from external sources. The process of manufacturing metal products is characterized by a significant impact on the environment, mainly due to high energy consumption. Energy used during production is a key source of pollutant emissions in all main categories of environmental impact, such as ecotoxicity (marine and freshwater), eutrophication of freshwater and toxicity to humans. In order to reduce the negative impact of operations on the environment, the enterprise should focus its activities on improving the energy efficiency of production processes.
