DST is used in Greenwich as in the rest of the EU. But Greenwich Mean Time is another matter entirely. GMT is not defined by our modern Time Zone standards, nor by the day to day position of Sun in the sky (which was how time was kept throughout most of human history), but by the longitude where Greenwich is located. The yearly average (mean) of Sun's position there determines GMT; Paris Mean Time is different since Paris has a different longitude. OTOH, their Standard Time is the same, since they're in the same Time Zone.
Except they aren't: Paris (and all of France) is one hour ahead of GMT. (No big deal, but I wanted to correct this before the error snuck into the Wikipedia.)
