Sanders’ amendment — Sanders #3 — would have required CCS-equipped plants to sequester at least 85 percent of their pollution in order to be eligible for additional free allowances. That’s what the bill used to mandate, before it was changed earlier this month. Sanders tried to change it back and was voted down with 13 “nays,” including one from his usual ally Barbara Boxer.

Sanders’ support of this bill may be irrelevant to its passage through committee. But if snubs like this aren’t enough to convince him to continue to oppose Lieberman-Warner, it will be a sign that deep greens have lost all support in the Senate.
