UN Climate Summit Ends With Fresh Pledges

A UN climate change summit has agreed to widen the use of renewable energy and raise billions of dollars in aid for developing countries.

The one-day summit, hosted by UN Secretary-General Ban Ki-moon, set goals to halt losses of tropical forests by 2030, improve food production, and hike the share of electric vehicles in cities to 30 percent of new vehicle sales by 2030.

The targets are meant to help prepare a 200-nation summit in Paris in late 2015 to finalize a deal to slow rising greenhouse-gas emissions.

Addressing the summit, U.S. President Barack Obama said a "global compact" needs to include strong commitments from some of the world's emerging economies because the amount of greenhouse gases they emit increases as their economies grow.

China surpassed the United States in 2007 as the world's largest greenhouse gas emitter.

China's vice premier, Zhang Gaoli, agreed that the world's two biggest emitters "have a responsibility to lead."

Zhang said China would aim to cap emissions or have them peak "as early as possible."

The leaders of India and Russia also failed to attend the New York gathering.
