US climate envoy says discussed plans for summit on methane at Beijing talks

US climate envoy John Podesta said on Friday that plans were moving forward for a summit with China on reducing emissions of methane and other highly polluting non-CO2 gases. China is the world's leading emitter of climate change-inducing greenhouse gases, including methane, followed by the United States.

Podesta said he had held excellent talks with Chinese counterpart Zhenmin and Foreign Minister Wang Yi in Beijing. The two sides had made plans to hold a summit on non-CO2 gas including methane, N2O and hydrofluorocarbons.
