Aug. 14 (Bloomberg) -- The U.S. Senate should abandon efforts 
     to pass legislation curbing greenhouse-gas emissions this year 
     and concentrate on a narrower bill to require use of renewable 
     energy, four Democratic lawmakers say.

     "The problem of doing both of them together is that it becomes 
     too big of a lift," Senator Blanche Lincoln of Arkansas said 
     in an interview last week. "I see the cap-and-trade being a 
     real problem."

     The resistance by Lincoln and her Senate colleagues undercuts 
     President Barack Obama's effort to win passage of legislation 
     that would cap carbon dioxide emissions and establish a market 
     for trading pollution allowances, said Peter Molinaro, the 
     head of government affairs for Midland, Michigan- based Dow 
     Chemical Co., which supports the measure.
