Nowadays the green finance is a very actually topic, which is becoming increasingly important in the agricultural sector. The sustainable agricultural production is more and more important in the European Union. The requirements and regulations are becoming stricter therefore we have to use sustainable technologies in the agricultural production and we need more and more green investments and financial sources to establish sustainable plants. In this study, we examined a case study and calculated the costs and the...

Environmental discourse has moved from -green- to -sustainable- to -circular.- The emerging paradigm is the regenerative economy, which goes beyond minimizing damage to actively improving ecosystems and communities. This perspective draws on long-standing work in ecological economics, systems ecology, and innovation theory without relying on specific frameworks in this abstract. It stresses that natural resources may be finite, yet the possibilities created by knowledge, technology, and institutional evolution are...

Futures Literacy Labs (FLL), as developed by UNESCO, have become a widely replicated and methodologically robust framework for anticipatory governance, now applied across more than 60 countries and multiple domains - from education to innovation policy and sustainability science [1, 2]. Recent studies emphasise their potential for transforming entrenched policy paradigms, surfacing assumptions, and fostering systemic innovation [3, 4]. While the integration of FLL into Green and Sustainable Public Procurement rema...

The European Green Deal (EGD) represents a transformative policy initiative aimed at shifting the EU economy toward climate neutrality and environmental sustainability.
