But of course: You can't have a viable carbon dioxide hoax scam swindle rip-offset market without a fossil-fueled army of people constantly driving around measuring trees for $125 per hour

In California, a Grand Experiment to Rein in Climate Change - NYTimes.com

LEGGETT, Calif. — Braced against a steep slope, Robert Hrubes cinched his measuring tape around the trunk of one tree after another, barking out diameters like an auctioneer announcing bids. “Twelve point two!” “Fourteen point one!”

Mr. Hrubes’s task, a far cry from forestry of the past, was to calculate how much carbon could be stored within the tanoak, madrone and redwood trees in that plot. Every year or so, other foresters will return to make sure the trees are still standing and doing their job.
...
That is why there is such a need for qualified verifiers. This summer, four foresters from around the country gathered in a Los Angeles suburb for a $2,900 test-preparation course to master the new system in advance of a required state test.
...
There are several basic requirements for a forest offset. Credits cannot be granted for preserving trees that were going to be left standing anyway. The change must be long-lasting: trees must be left intact for a century. And owners must hire accredited verifiers to audit their claims.

The offset marketplace is already beginning to hum as companies gear up for California’s rollout.

Independent verifiers can make $800 to $1,200 a day, according to Mr. Bubser. Scientific Certification Systems, Mr. Hrubes’s employer, which verified 4.2 million tons of carbon offsets around the world last year, added two foresters this summer, for a total of six.
