The 10 states with the highest greenhouse gas levels account for nearly half of all America's emissions, while the bottom 10 add up to just about 3%.

Though we may be the US of A, we're clearly not as united on pollution prevention. Obama's Clean Power Plan, released earlier this week, set ambitious greenhouse gas reduction targets, but left it up to individual states to decide how to achieve them.
