The UN concept of “sustainable development” is increasingly penetrating various spheres of life, subordinating not only political interests, but also forcing economics and science to work closely together to preserve a favorable environment, biodiversity and reduce climate emissions. On the one hand, in the current global paradigm, this attitude is mainly positive, as it aims to achieve the goals of the Paris Climate Agreement, prevent negative environmental impacts and other high goals, including the protection of the interests of future generations. However, the “green fever” that is sweeping the world, namely the race of states and various international organizations, carries significant risks. The goals and economic targets set by Governments are sometimes not just overly ambitious, but simply unrealistic and utopian, as in the case of the transition to blue hydrogen in the next five years. In addition, another problem associated with the implementation of the principles of sustainable development is the problem of abuse of rights in the financial market, as well as increasing the competitiveness and attractiveness of investments in this area through the issuance of specialized securities, the so-called “green bonds” or their specialized variety of “blue bonds”. However, it should be noted that with all the marketing activities that accompany the issuance of each financial instrument of this type, it is currently impossible to ensure their liquidity solely for supposed good purposes. Thus, without a clearly formulated economic plan confirming the real financial attractiveness of both projects on the introduction of blue water and projects on the issue of blue bonds, both are doomed to very low performance.
