OOPS

Nicholas Kristof reported in the NY Times (via Reason)that Portland had found the secret to eternal motion, cutting CO2 emisions while paying no price and growing the economy:

Officials in Portland insist that the campaign to cut emissions has entailed no
significant economic price, and on the contrary has brought the city huge
benefits: less tax money spent on energy, more convenient transportation, a
greener city and expertise in energy efficiency that is helping local businesses
win contracts worldwide.... Portland's experience is so crucial. It confirms the
suggestions of some economists that we can take initial steps against global
warming without economic disruptions. Then in a decade or two, we can decide
whether to proceed with other, costlier steps....

Here's his big conclusion:

Perhaps eventually we will face hard trade-offs. But for now Portland shows we
can help our planet without "wrecking" our economy--indeed, at no significant
cost at all.

No one, particularly the science-challenged press who oh-so-wanted this to be true, asked themselves if this made any freaking sense at all.  Apparently, it doesn't:

In response to data requests from the Cascade Policy Institute, a Portland-based
think tank, the [Office of Sustainable Development] admitted that a math error
resulted in a 2004 carbon dioxide calculation that was 74,561 tons too low. The
re-stated total puts Multnomah County above the 1990 levels by more than 68,000
tons.

The implication?

What's more, Cascade's prez, John Charles, argues that, beyond bad math, there
are more basic methodological flaws that lead to an undercounting of
transportation-related emissions. "Portland's claim of painlessly reducing
carbon dioxide has been repeated over and over by journalists, bloggers, and
even some scientists for the past month, without any attempt to verify the
accuracy of the OSD's report," he writes. "In fact, actual carbon emissions have
been well above the level claimed by Portland, and any regulatory program
imposed by the government to lower emissions to pre-1990 levels is going to be
costly to consumers, something elected officials apparently don't understand."
