Why would Obama not curb smog emissions? Gore has a few ideas.

Al Gore: He’s not happy with Obama. President Obama has recently halted regulations that would curb “smog-creating emissions until at least 2013”. According to Gore, the “result of the White House’s action will be increased medical bills for seniors with lung disease, more children developing asthma, and the continued degradation of our air quality.” He also likened Obama to George W. Bush, a seemingly low blow. source
