...little-known source that is not covered by any national or international regulations: global marine shipping. The massive container ships that ply the ocean lanes are the backbone of 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...
...question, even burying analysis from its own scientists in the waning months of that Administration. When President Barack Obama took office, he directed the new EPA to kick-start the regulation process - nearly 11 months and 380,000 public comments later, the agency is now poised to regulate CO2 as a pollutant. "This cements 2009's place in history as the year the U.S. government began seriously addressing the challenge of greenhouse-gas pollution," said Jackson...
...their part, business groups and many conservatives remain even more opposed to the possibility of EPA regulation of greenhouse gases than they do to a cap-and-trade bill. They say CO2 is far more prevalent than any other pollutant the EPA has ever attempted to regulate under the Clean Air Act and that top-down regulation would lay a heavy burden on U.S. business. "An endangerment finding from the EPA could result in a top-down command-and-control regime that will choke off growth by adding new mandates to virtually every major construction and renovation project," said...
...easy to rush to condemn projects like these that seem counterintuitive to the very logic of the CDM. But the planet's atmosphere is perfectly happy with the tradeoff, says Derwent of the IETA, "just as much as it would be happy with the reduction of CO2 over a long period by the adoption of wind power in the place of coal." What matters is the absolute reduction in carbon emissions, regardless of the source, he says. "That's what markets do, they find the cheapest, most cost-efficient way of producing whatever it is that's demanded," says Derwent...
Another way to get a green cleaning is to use liquid carbon dioxide. CO2 is nontoxic - thankfully, since so much of it is in the atmosphere. In CO2 cleaning, clothes are put in a vacuum chamber with gaseous and liquid CO2, which dissolves dirt and oil. The drawback here is price: a new CO2 dry-cleaning machine can run more than $100,000. Cleaning green "does take longer and cost more," admits Kistner. How much more? Green Apple charges at least $6.16 to clean a shirt using wet methods or CO2.
