"We have substantive hopes in China, to be honest, that China will take the lead ... to make the low-carbon economy, the high energy efficiency economy a reality in the coming years," said Stephan Singer, the head of energy policy for the WWF environmental group.
"That's not the case in the U.S., unfortunately," he said. "We would need to see similar or even stronger targets there" in the U.S.
SHOOT: Our total energy consumption needs to come down, whichmeans efficiencies must go up substantially, and populations must no longer grow.
The United States still consumes more energy and oil per capita than China.
China's energy consumption has more than doubled in less than a decade, from 1.107 billion tons in 2000 — driven by its burgeoning population and economic growth that hit 11.9 percent in the first quarter of 2010.
