US president Barack Obama has proposed a limit to carbon emission on new power plants built in the US as a step to reduce pollution blamed for global warming. He aims focus on climate change and to end the “limitless dumping of carbon pollution” from US power plants. 
The limit for the new gas-fired power plants restricts their carbon dioxide emissions to 450kg or 1,000lb per megawatt hour. And the limit for new coal-fired power plants are to 1,100lb. Regardless, on average, coal plants emit about 1,800lb of carbon dioxide on hourly basis.
The proposal is disputed by the coal industry and congressional Republicans. Even though the plan seems to have been working since April 2012, it is facing steep resistance from the both. The limit proposal would eventually inflict struggle for existing power plants that held accountable for about a third of all US greenhouse gas emission. The costs that the power plants would have to incur to capture their carbon emissions may harm job creation and employment in the industry (In order to meet the standards, coal plants would have to install expensive new carbon capture technology to minimize its emission of carbon dioxide to the air.).
