US climate envoy John Podesta intends to travel to China „later this year“ and continue the bilateral climate talks between the two largest carbon emitters. The talks will focus on reducing non-CO2 emissions, such as methane emissions and industrial nitrous oxide (N2O – also known as laughing gas), as reported by the South China Morning Post. Reducing N2O emissions is „an affordable and relatively straightforward way“ to reduce greenhouse gases, Podesta said at an event. The United States and China account for around 80 percent of industrial N2O emissions.
