So, finally it is time for the Rio+20 conference. It will be very interesting to see whether or not the world leaders that now gather in Rio will be able to take the important steps needed in the direction of sustainability. The lack of real results from the last UN climate change conferences do not make you to optimistic, do they? Nonetheless, as is often the case, some very interesting documents and inspiring thoughts have been published prior to the meeting. One of the topics that have caught my interest is UNEP's "new balance sheet for nations", the launch of the metric IWI (Inclusive Wealth Index) instead of GDP. Read about it - it seems like that would be one step in the sustainability direction!
