Ethical shopping made easier with the Carbon Credit Card
Still in the planning stage but just awaiting some conceptual breakthroughs, Environment Secretary David Milliband proposes our credit cards show us just how much carbon emission each purchase costs - right on the card itself. The Emissary Credit Card Concept has a paper-thin screen embedded in the card surface that would show an easy-to-understand graph of what your carbon consumption is (and presumably give you equally on-the-fly opportunities to offset it). Current technology won't quite cut it, but a refinement in flexible screens is all we need to make this a reality. (Interestingly, flexible tech is mostly based on OLEDs - that's organic LEDs, using technology based on butterfly wings and jellyfish glow - so nature may be the one to provide the answer here.) [GT]
