But, barring a more in-depth veto statement, it's possibly not the best big-picture move.
I suggested a couple of weeks ago that Obama should make such a statement, pledging to pass a similar bill if it were tied to a carbon tariff and carbon tax.
Today's announcement story explains why:
Last year, an 11-volume environmental impact review by the State Department concluded that oil extracted from the Canadian oil sands produced about 17 percent more carbon pollution than conventionally extracted oil.
The AP notes that Obama's veto was without fanfare. Well, per my angle, it should have had some fanfare indeed.
And, note the "no fanfare" in the AP story link.
In other words, President Obama can often be an "on the one hand" environmentalist.
