While environmental activists played their part yesterday during demonstrations at the capitol building, going so far as to dress up as solar panels and to sing the tune of “You Are My Sunshine,” their counterparts, the anti-cap-and-trade contingency who has been testifying before the Environmental Improvement Board during hearings on repealing a year-old law to reduce greenhouse-gas emissions, did the same. In a Manichean battle pitting good versus evil, one of Wednesday’s key witnesses was none other than a man labeled in 2002 as the “Clean air villain of the month,” who was testifying on behalf of Tri-State Generation and Transmission Association, an oil, gas and utility interests seeking to overturn the EIB’s 2010 measure, As outlined in an earlier New Mexico Independent story, Governor Susana Martinez has been seeking a repeal of the EIB’s 2010 edict that the state require its utility industries and other large emitters of carbon dioxide to cut their emissions of the gas by two percent a year beginning in 2012 and running through 2020. Martinez has argued — along with the representatives of the Public Service Company of New Mexico, the New Mexico Oil and Gas Association and other oil and gas and utility companies — that the measure harms these businesses, incurs unjust fees on them and that any climate change regulation ought to take place on a national, not state level.
