There are two pieces there. There has been increased effort in the last few years to give additional attention to horizontal items. They're items where more than one department is receiving money for a linked initiative.
Members of Parliament, when they were studying estimates in the past, were concerned that if they only saw the bits in each department, they would never see the whole picture. By putting in some additional pages to flag horizontal items, members, when they study things like the Copenhagen Accord, can see which departments are getting money. They get a picture of the whole initiative.
Can I say there's an increasing trend to multi-department initiatives? I'm not sure that's true necessarily, but there is certainly an increasing trend to provide additional disclosure around those things.
