In this paper we summarize some of the results of the Herschel Open Time Key Programme DUNES (DUst around NEarby Stars). This project aims at detecting and studying cold dust discs, i.e. Edgeworth-Kuiper-belt analogues, around FGK stars of the solar neighbourhood, in a volume-limited sample. The sensitivity and wavelengths of the two instruments used, namely PACS (70, 100 and 160 micron) and SPIRE (250, 350 and 500 micron) are the appropriate ones for these tasks. Despite of the fact that, at the time of writing these proceedings, only about half of the sample has been observed, new results and increased statistics with respect to previous surveys and observations have emerged. Some new, unexpected results, in the form of very cold discs, pose some challenges to the current modelling paradigms. Note that at the time this paper is published, the results given and some of the conclusions will be obviously out of date.
