Hi Carsten,

This might not immediately provide you with an answer as to what existing legislation but may provide you with a frame on how to categorise or identify the various legislation. What our paper does is to theorise the categorise the contribution of Social Value... by using the input, process, output and environment. So this is initially applied in Organizational Social Value  but you can use this as pretext for identifying which aspect of the business does the legislation has... rather than just plainly stating about the Business....

in addition to this you might want to employ a systematic literature review to compile all the research articles or legislation. Just message me if you need help with compiling research articles..

Dear Harry,

thanks for this. - Happy if you would share your paper (ideally in our forum: http://www.eklipse-mechanism.eu/forum_discussion?p_p_id=forumdiscussions_WAR_EklipseSBportlet&p_p_lifecycle=0&p_p_state=normal&p_p_mode=view&p_p_col_id=column-1&p_p_col_count=1&_forumdiscussions_WAR_EklipseSBportlet_mvcPath=%2Fhtml%2Fforumdiscussions%2Fview.jsp&_forumdiscussions_WAR_EklipseSBportlet_themeId=8#eklipsef_subjects_top)

or here...

As for the issue of systematic review: This here is currently a scoping as first step in a potential systematic knowledge synthesis process - one option for this would be a systematic review, but this of course depends on the suitable number of papers out there and the concrete question we will address (EKLIPSE has a set of 21 potential synthesis methods).
