Today the United States’ Environmental Protection Agency (EPA) is holding a public hearing on plans for more stringent pollution standards in power stations.

The hearing in Washington D.C. will last all day and take views from the public on proposals to bring in a national limit for the amount of carbon emitted by new power plants.

Currently, there are no uniform national limits on the amount of carbon pollution new power plants can emit.

President Barack Obama asked the environment body to get a standard in place quickly under the White House’s Climate Action Plan announced last June.

Power plants are the largest concentrated source of emissions in the United States, accounting for roughly a third of all domestic greenhouse gas emissions according to the White House.
