Campaigners marched in Dublin and across Europe, demanding a halt to new data centres.

Reported, not verified. We read 2 organiser primaries: the Friends of the Earth Ireland event page, which carries the date, time, route and demand and now says the event is over, and stopdirtydatacentres.eu, which lists the programme. Neither publishes a post-event record. The march itself, and its size, come from the Irish Times at 16:10 on November 7.

We read 2 organiser primaries. Friends of the Earth Ireland's page at friendsoftheearth.ie carries the Dublin action: Saturday November 7, 2026, 12:00 to 14:00, Garden of Remembrance to the Dail. It now reads "This event is over and booking is closed." The demand is a government moratorium on new data centres, framed as an urgent climate, energy security and cost of living step. Its figures: data centres use 23% of Ireland's electricity, the highest per capita in the world, and directly employ 3,300 people, about 0.1% of the workforce. The page calls the march one of 80 events in 16 European countries, and elsewhere says over 100 groups are joining. European coordinators named: Global Action Plan, Green Web Foundation, Leitmotiv, Tu Nube Seca Mi Rio, the Spanish Strategic Litigation Group, Friends of the Earth Ireland, Data 4 Good, APRS Scotland, the Equinox Initiative for Racial Justice. Irish supporters named: An Taisce, BOLD Climate Action, Climate Justice Universities Union, Not Here Not Anywhere, Kildare Data Centre Awareness, Futureproof Clare, Kilmeadan Against Industrialisation. The coalition site stopdirtydatacentres.eu lists November 6 and 7 as European Days of Action across about 13 countries by our tally: the United Kingdom, France, the Netherlands, Spain, Austria, Italy, Germany, Poland, Ireland, Finland, Denmark, Croatia, Belgium. Cities include Amsterdam, London, Paris, Brussels, Vienna, Madrid, Barcelona, Warsaw, Dublin, Helsinki, Berlin, Leeds, Bristol, Zagreb, Turin. Its demand is an immediate moratorium on large European data centres. One London event is marked cancelled for lack of a venue. Organisers include GLOBAL 2000 and AlgorithmWatch; supporters include Greenpeace UK, Greenpeace Germany, Global Witness, EDRi. Neither site publishes a post-event record. Reported, in neither primary: the Irish Times at 16:10 on November 7 has hundreds marching from Parnell Square to Leinster House; Rosi Leonard of Friends of the Earth Ireland cites an estimate of about 360 euros in extra household electricity costs from 2015 to 2023, and says wholesale prices doubled in 12 months; Paul Murphy of People Before Profit puts about half of Ireland's 124 data centres in one council area; the Social Democrats, Green Party, People Before Profit and Sinn Fein attended. Euronews on November 5 had over 100 rights groups in 15 countries, European data centre investment rising from 12 billion euros in 2020 to 25 to 26 billion this year, and 176 billion forecast from 2026 to 2031 by PwC.
