Best examples have been painstakingly compiled by Edwin Datschefski (products), David Bergman (furniture),
and Alastair Fuad-Luke (ecoDesign: a sourcebook)
New eco/design blogs such as metaefficient and treehugger keep us current on consumables, with variable 'green' standards. These days, as ever, the newest and best examples always hit Metropolis first (see Tangents)
(Eco-architecture is largely excluded here because,
earthships to skyscrapers, it's represented elsewhere plenty enough, thanks.)
