RIO DE JANEIRO (Reuters) - Reaching a binding climate deal at the upcoming U.N. conference in Mexico will likely be difficult, delegates from a group of developing nations said on Monday, spurring further doubts about a global climate accord this year.
Environment ministers from Brazil, South Africa, India and China -- known as the BASIC group -- meeting in Rio de Janeiro said developed nations have not done enough to cut their own emissions or help poor countries reduce theirs.
