...globalization, but they are also carbon hogs. Each year, about 100,000 ships contribute some 1.3 billion tons of CO2 to the atmosphere, about 3% of global carbon emissions. In addition, ships spew out huge amounts of traditional air pollutants, like nitrous oxides (NOx) and sulfur oxides (SOx), and emit black carbon soot, a leading contributor to melting Arctic ice. "It's an overlooked and important problem, but it's also extraterritorial," says Travis Bradford, the chief operating officer of the Carbon War Room, based in Washington, D.C. "And there's no external force that will cause the shipping industry...
...generate credits because they have the most to clean up and often have the resources to make improvements. Fluorochemical companies in India, for example, have been the biggest generators of CERs for the global market. That's because companies like SRF, a fluorochemical company headquartered outside of New Delhi, emit a gas called HFC-23 during the process of making chemicals for refrigerators and air conditioners. HFC-23 is 11,700 times more harmful to the atmosphere than carbon dioxide. SRF invested $3 million to equip its factory to burn the gas instead of releasing it into the atmosphere...
Typical lasers emit one beam of a single, exact wavelength, but a group of researchers have created a new laser that can emit multiple beams of different wavelengths...
...could soon be filled with green ships. Corbett predicts that if the new IMO standards are implemented, then the shipping industry could avoid contributing to more than 40,000 deaths in a single year. It would be a dramatic drop, but the ship engines would still be allowed to emit more sulfur dioxide than trucks and cars in the U.S. Solar Sailor's Dane sees the shipping industry's evolution away from oil as inevitable - even obvious: "Why go back to the land to refuel a boat when the energy is out there in the waves, sun and wind...
...decision to regulate which bulbs consumers can use has drawn some criticism. CFLs emit light in a different spectrum than that of their incandescent counterparts. Light produced by CFLs is "cooler" - tinged a light blue or green - than the yellowish glow of an incandescent, and many people complain that the effect is less aesthetically pleasing. CFLs raise concerns because there is a danger of mercury exposure if the bulbs break, which makes disposal tricky. And some people allege that long-term use of fluorescent light causes health problems, though experts are largely skeptical of the claim...
