CLIMATEWIRE | NOAA is celebrating a rare event: progress by the United States in detecting what is believed to be the world’s most potent greenhouse gas, and then working with businesses to reduce its emissions. “This is a great example of the future of greenhouse gas emissions tracking, where inventory compliers and atmospheric scientists work together to better understand emissions and shed light on ways to further reduce them,” said Steve Montzka, a senior staff scientist at NOAA’s Global Monitoring Laboratory. But they only account for 50 percent of the global SF6 emissions found in atmospheric observations taken from 1990 to 2007
