Attempts to include this in the following treaties in 2000 and 2007 both failed. However, in September 2008 Parliament held its first full plenary session in Brussels after the ceiling of the Strasbourg chamber collapsed during recess forcing the temporary move. The unique architecture of the European Commission's Berlaymont building is utilised in its official emblem. Likewise, the official emblem of the European Council and Council of the European Union features the Europa building's distinctive multi-storey "lantern" shaped structure where meetings for both of these institutions take place. European Parliament The Parliament is bound to spend "twelve periods of monthly plenary sessions, including the budget session" in Strasbourg, while additional sessions and committees are in Brussels. The secretariat is in Luxembourg City. While the split arrangements for other bodies have relatively little impact, the large number of members of the Parliament and its concentration of work load means that these issues are far more contentious than those surrounding the other institutions. A democratic question has also been raised in the European Parliament being one of the few parliaments in the world which cannot decide its own meeting place, and also being the only parliament to have more than one seat. Critics have described the three-city arrangement as a "travelling circus" with a cost an extra 200 million euro over a single location. Defenders of the Strasbourg seat, like the MEP for Germany Bernd Posselt, however claim that the figure is rather a mere 40 million euro, i.e. an extra cost of 8 cents per EU citizen. When Parliament was forced to meet in Brussels in September 2008, due to a fault in the Strasbourg building, it was estimated that Parliament saved between €3 and 4 million, though the exact figure is hard to calculate. As the commission also meets in Strasbourg when Parliament is out of Brussels, the cost of Commissioners moving amounted to €9.5 million between 2002 and 2007. The Green party has also noted the environmental cost in a study led by Jean Lambert, MEP and Caroline Lucas, MEP; in addition to the extra financial cost, there are over 20,268 tonnes of additional carbon dioxide, undermining any environmental stance of the institution and the Union. Jens-Peter Bonde, former leader of the ID group, stated in 2007 that unless the issue of the seat was tackled, it would be impossible to increase the election's turnout, as the movement of
