A report issued today by the National Research Council recommends that the US set a measurable domestic greenhouse gas (GHG) emissions budget in the range of 170 to 200 gigatons of CO 2 -equivalent (eq) for the period 2012 through 2050. A carbon-pricing system is the most cost-effective way to reduce emissions. Source: NRC.
