Greyhound gets some competition from Megabus.com

Buses, on average, get low passenger miles per gallon in the U.S., because they stop often and don't use most of their capacity. Coach buses -- providing prebooked travel between cities -- don't suffer from these limitations.

Megabus.com, a new niche player in this market, provides cheap, comfortable travel between nearby cities with travel time comparable to driving or taking commuter airlines (in a very small portion of the U.S.). Efficiency is 184 passenger miles per gallon -- without using hybrid buses or using any particular efficiency technology. They just use yield management ticket booking, where the earlier you book a ticket (relative to other passengers) the less you pay for your seat. (Thanks, Jordan Hayes for the tip.)

Double counting does not legally qualify as fraud

The ENDS Report -- July 2007, issue 390 ($ub. rqd):

ENDS has learned that chemical corporation Rhodia is using carbon credits from the Clean Development Mechanism (CDM) to meet voluntary corporate targets -- only to sell them at a profit to be counted again elsewhere. Cement company Lafarge has not ruled out the same practice.

Companies like Rhodia can use CDM credits to comply with mandatory targets under the EU Emissions Trading Scheme. But they can also use them to meet voluntary carbon reduction commitments or to make "carbon neutral" claims, or sell them on the market.

Rhodia and other companies are counting the credits they generate towards their own voluntary emissions reductions and then selling them, thereby enabling other organizations to claim the reductions as well.

This is not a problem of a "few bad apples," or a flaw in the offset market that can be fixed. The fundamental problem with offset trading is that compliance is less transparent than a tax or auctioned permit system or even old-fashioned, non-market regulation. There is more room for deliberate gaming, and more room for honest error. At the same time, a working offset market depends on fewer errors and more precision than other means. An offset that is a formal permit to pollute (like CDM) actually increases emissions if it is implemented less than perfectly. Offsets such as CDM don't make allowances for human imperfection to the same extent other means of controlling carbon emissions do.

[Update] Stephan Singer Head of European Climate and Energy Policy Unit of the World Wildlife Fund claims that if LaFarge in fact does sell their voluntary credits on the CDM market they will be violating their agreement with WWF.

They just keep coming

There is constant drumbeat of accusations of hypocrisy against Al Gore for using offsets. Although the people who do this sort of thing are aiming for the lizard brain, I suppose it is worth pointing out that it is an obviously bogus accusation.

Look, I'm an offset critic. I think offsets are one of the biggest wrong turns we can make in fighting environmental destruction, especially global warming. Al Gore, on the other hand, is a strong advocate of offsets. He helped get them into the Kyoto treaty. If I were to buy offsets, I would be a hypocrite -- acting against my beliefs. When Al Gore buys offsets he is acting according to his beliefs. Regardless of whether those beliefs are right or wrong, no hypocrisy is involved.
