US fends off `too ambitious' emissions guidelines at climate talks

The United States rejected fresh demands that it accept ambitious guidelines for negotiating future cuts in emissions of global-warming gases, as the UN climate conference entered its last days. Pressure came even from a one-time ally on climate, Australia, whose new prime minister urged Washington to "embrace" new binding targets. But UN Secretary-General Ban Ki-moon, after opening the ministerial-level final segment of the two-week meeting, told reporters Wednesday he believed suggesting specific emissions guidelines in the "Bali roadmap" for future talks may prove "too ambitious."
