Six councils - Hillingdon, Wandsworth, Richmond upon Thames and Hounslow LBCs, Slough BC and Windsor & Maidenhead RBC - are marching with campaign groups in an attempt to ward off plans for a third runway and end runway alternations.
They join eight other EU countries also holding demonstrations against airport expansion this Saturday.
The councils are mounting opposition to the Department for Transport's consultations on 'mixed mode' flights - simultaneous landing and take-off - and airport expansion, which could see daytime flights increase by over 1,000 a week. (LGC, 10 January).
'In Hillingdon, pollution around the airport already exceeds EU guidelines while a third runway and sixth terminal will mean at least 700 homes being lost locally and historic villages being wrecked forever.'
Hounslow's head of environmental strategy, Rob Gibson, said: 'We recognise the contribution the airport has made to the local economy, but that does not mean it can keep on expanding at any cost. Heathrow is a proven economic success, but it has clearly reached the limit of its sustainable development.'
