User Evaluation of Innovative Megaprojects Induced by Environmental Change Using Primary Data

The modern age and the associated rise in living standards have been achieved at the cost of enormous environmental damage. The environmental degradation of today, the environmental devastation of previous years, and global warming have presented the world with new and novel challenges that were not experienced in previous decades. Rising sea levels, increasing energy demand and the explosion in energy prices have created new focal points in the thinking of all spheres of economic life. All these environmental factors require a new and fresh approach to future sustainability. New solutions to energy supply are needed and solutions to sea-level rise must be sought. In this article, we undertake to examine in detail the Maldives floating city and the European energy island project from a user's perspective, specifically in terms of its progress and exemplary value. In this paper, we will examine the two flagship projects through the results of a primary research conducted in 2022 and 2023, formulating the main messages for the design of future projects.
