Carbon Emission

China emits over a quarter of the world's carbon--some 10 billion tons. That's twice what we pump out here in the U.S. But before the finger-wagging begins, consider that a quarter of China's CO2 emissions come from making exports--in other words, stuff for countries like us. "So we're talking about five or six [percent:portion] of global emissions are in these goods being exported from China. And that may not sound like a lot, but five or six percent of 35 billion tons is a lot of CO2."Steve Davis is a climate energy [scientist:entrepreneur] at the University of California Irvine. He and his [colleagues:friends] wanted to see whether outsourcing manufacturing to China--which happens to be good for our wallets--is also good for the planet. Spoiler alert: doesn't look like it.Because China is so reliant on coal for their energy, and because also they use less advanced [technologies:methods] and [processes:facilities] in some cases, there's a lot more CO2 being produced than if those same goods were made in developed countries.
