Citation:
Beaulieu, J. U.S. EPA Webinar: Overview of U.S. GHG Inventory and Recent Improvements. U.S. EPA Webinar: Overview of U.S. GHG Inventory and Recent Improvements, Cincinnati, OH, June 01, 2022.
Impact/Purpose:
On Wednesday, June 1, 2022 at 1PM EST, EPA and interagency inventory staff (e.g. USFS) will hold a webinar on the latest annual Inventory. At the webinar, EPA will present an overview of the latest GHG Inventory findings in the report, review recent improvements, note future work, and allow time for questions.
Description:
Flooded lands are defined as water bodies where human activities have 1) caused changes in the amount of surface area covered by water, typically through water level regulation (e.g., constructing a dam), 2) waterbodies where human activities have changed the hydrology of existing natural waterbodies thereby altering water residence times and/or sedimentation rates, in turn causing changes to the natural emission of greenhouse gases (GHGs), and 3) waterbodies that have been created by excavation, such as canals, ditches and ponds (IPCC, 2019). Flooded lands are sources of carbon dioxide and methane to the atmosphere. This slide presents estimates of GHG emissions from US flooded lands greater than 20 years old in 2020.
