What percentage of the world's "carbon emissions" come from the United States?

Terry Tamminen (Author & Environmental Policy Advisor) gives expert video advice on: What percentage of the world's "carbon emissions" come from the United States?; Do I have to choose between a healthy economy and a healthy environment? and more...

The United States is home to 5 percent of the world's population but 25 percent of the world's greenhouse gas emissions. And I argue that we're actually home to much more of that, because countries like China and India, with their emerging economies and where they're building 1,000 megawatts a week of coal-fired power plants, that electricity that they're building the capacity of is to power factories that are producing plastic flamingos and Nike shoes to sell to Wal-Mart to sell to the United States. So we are the direct or indirect cause, in my view, of at least half of the world's carbon emissions.
