Halting vs braking?

Bush climate plan said too little, too late  

On Wednesday, President George W. Bush unveiled a plan to halt the growth of U.S. emissions by 2025, toughening a previous goal of braking the growth of emissions by 2012. The United States and China are the top emitters. 

I don’t understand how allowing oneself an extra 13 years to achieve what appears to be the same goal is “toughening” it. Is this a typo, or am I misreading it?
