Greenpeace is always scaling buildings with one message or another. But here’s a first – a positive message. The campaign whizzkids have today conquered a building (nothing new there), but this particular building is the all new singing and dancing St Pancras station in London. To welcome the new Eurostar route, the eco freaks have put up a huge banner on the station’s building. For once, it reads ‘YES!’, instead of ‘NO’. Very smart move. Of course, the subtext is to remind people of their campaign against airport expansion and promote rail travel. Hence the small(ish) print on the poster “P.S. Gordon, no need for that third runway”, a reference to enlarging the hideously crowded Heathrow Airport still further. Whatever your views on that, Greenpeace UK continues, in my view, to be the best NGO of all at eye-catching campaigns, always with the crucial ingredient of the unexpected thrown in. See Greenpeace.
