If the shipping industry were a country, it would be the sixth-biggest industrial carbon emitter in the world. Whereas big countries have plans for cutting emissions, shipping does not. The UN climate talks in Canciin are unlikely to change that. But customers, who indirectly pay for shipping fuel, might be better placed to put pressure on the industry. To help them, a "do tank" (yes, really) called the Carbon War Room has set up a website designed to rate ships as if they were refrigerators or boilers. Shipping-efBciency.org uses data from ihs Fairplay, a vessel registry, to calculate how fuel-efficient each ship was at the time it was built.
