The same inventory notes that forests, croplands, grasslands, wetlands, and settlements together absorbed enough carbon to offset roughly 13 percent of that gross number, leaving the land sector as a net sink rather than another smokestack on the ledger. That single line, buried in a technical appendix, is one of the more consequential facts in American climate accounting. It is also a fact the country may soon stop measuring. The EPA has proposed permanently removing reporting obligations for most categories of industrial facilities under the Greenhouse Gas Reporting Program, the data pipeline that has fed the national inventory. In the months since, the agency has extended reporting deadlines, by which point the rule stripping the requirement may already be final. What the 2022 inventory captured, in other words, is a snapshot of something the federal government is in the process of no longer looking at. What the 6,343.2 million metric ton figure actually contains The gross number sums carbon dioxide, methane, nitrous oxide, and a set of fluorinated gases,...
