Carbon dioxide capture and storage beneath the seabed is a relatively new concept and its regulation is still in development. Neither international law nor European Union law cover the issue thoroughly. The author discusses challenges of tackling climate change and looks into carbon dioxide subsea storage from the perspective of maritime environment protection. There are no international conventions on carbon dioxide capture and storage beneath the seabed. The analysis of legal systems leads to conclusion that Polish domestic regulation of the issue is ahead of international law. It must be noted however that carbon dioxide may only be stored in accordance with the new law when there is no threat to the maritime environment.

In this article I present the problem of identity of objects (that persist in time and space) and their identification (also in time and space, when these objects persist and change their location) indicated in the title of the paper. I therefore present an outline of P.F. Strawson’s proposal, but also a purely formal approach that can be found in formal sciences (logic and mathematics). In the final part I give some ontological solution to Strawson’s research. It is a solution based on formal considerations within the so-called ontologically oriented versions of modal and temporal logics, which I proposed in my book Indywidua. Idee. Pojęcia (2008).
