Thanks for your designs. We like the layout of the text in #31, and the relative weighting it infers, but we're wondering if different colours might be used.
We like the depth (or 3d-ness) of the symbol, but the actual symbol isn't really working at this stage, because it's too similar to the good old recycling logo, and doesn't add enough meaning to the words.
Please see the general discussion on the contest for some more comments by us on the symbols.
Thanks for your feedback. Actually, the icon represent "360 degree" (holistic solution), as full circle. 3D style represent architectural/ building and land aspect. 3 shape as one circle represent 3 element (people->dark grey, building-> light grey and environment-> light yellow) that connected each other. But I'll try to create new icon base on your direction.
