UNITED NATIONS (Reuters) - A United Nations summit on climate change agreed on Tuesday to widen the use of renewable energy and raise billions of dollars in aid for developing countries in an effort to increase the prospects for a wide-ranging deal to slow global warming.

The one-day summit, hosted by U.N. 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.
