The United Nations Global Nitrous Oxide Assessment signals that emissions of what it identifies as the third most important greenhouse gas are rising faster than expected and calls for immediate action to curb environmental, and, more significantly, health impacts.

"This assessment sounds the alarm on a relatively forgotten super pollutant that contributes greatly to climate change and air pollution," Martina Otto, head of secretariat of the UNEP-convened Climate and Clean Air Coalition, said in a release along with the launch of the report.
