The University of Maryland published an inventory of U.S. greenhouse gases Wednesday, filling a hole created when EPA abandoned the process last year.
The report by the school’s Center for Global Sustainability was released on the same day EPA used to publish its tally of planet-warming gases in compliance with a 1992 climate treaty — April 15. The agency stopped making the inventory public last year for the first time since 1997. It never explained why it made the change, but the move came as President Donald Trump shuttered climate programs and withdrew from global pacts to address the problem.
Trump announced in January that the U.S. would leave the U.N. Framework Convention on Climate Change, which had obligated the government to compile the annual inventory.
The UMD inventory uses the same methodologies that were used by EPA in its recent greenhouse gas inventories, the report states.
