  Since the appearance of Bitcoin (2009), blockchain technology has been used in many fields. Companies use it for financial services, goods tracking, data authentication and secure storage, among other things, in order to make their operations more transparent and efficient. This technology has revolutionized the data management and transaction processing, but the associated costs are also significant and relevant to understand. The costs of blockchains vary and depend on the type of blockchain and how it is used. In this article, we examine the costs of using blockchain technology based on international literature, studies and reports with systematic literature review. In the results the range of possibilities offered by technology is presented, as well as the technology related cost types, and expenditures what companies have to deal with.

  Logistics processes have an increasingly significant environmental impact, which is partly caused by a lack of knowledge or priority for green logistics. Emissions from transport, energy consumption related to production, storage and material handling, as well as packaging waste are all serious burdens. At the same time, environmentally friendly solutions can improve the image of companies. The goal of a green supply chain is not only to deliver products to the consumer, but also to reduce environmental impact while maintaining efficiency and reliability. Sustainability strategies such as reducing the carbon footprint or increasing energy efficiency are crucial. The topic was examined by systematic literature analysis based on the Web of Science database (2014–2024), using the PRISMA methodology. According to the results, from 2021 onwards, digital technologies (e.g. blockchain, Industry 4.0, artificial intelligence) have come to the fore, which will determine the future of green logistics and further research directions.
