Colleagues at the Scripps Institution of Oceanography (lead author: Dr Jooil Kim) and institutes around the world have recently published work detailing the breakdown of perfluorocarbon (PFC) emissions from the aluminum and semiconductor industries. While we found in earlier work that reports to the United Framework Convention on Climate Change only accounted for about half of the total emissions we derived using atmospheric observations, Kim et al., have found a way to apportion the total emissions and this discrepancy to the two main industries. The Scripps Institution of Oceanography has published their story here.
