Utrecht based ad agency Spranq made a font environmentally friendly by making holes in the glyphs. The result is called Ecofont, and according to an article by NPR, this will save its users up to 15% in ink. The idea is that you set this font, a free download, as the standard font for printing drafts and e-mails and such. Ecofont is based on the liberally licensed Bitstream Vera font.
