Thank you Mark for the mail informing me of the discussion on ISO 26000. I am glad to see the contribution of Sidney to this discussion. I have been out of this forum for quite a long time due to many reasons, illness is one of them. Once in a while I visit the blog section to check my old blogs. I am still active in the area of Sustainability. By the way my second Ph.D.student has just submitted his thesis on Environmental Accounting in Agriculture. Hope I shall start contributing to the discussion soon.
