GHG Emissions of Livestock Manure Management Operations and the Mandatory Reporting Requirements in the USA

Livestock operations with their manure management systems (MMSs) cause emissions of greenhouse gases (GHGs). In 2009, the USEPA promulgated 40 CFR Part 98 Subpart JJ — Manure Management rule toward reporting of these GHGs caused by the MMSs. This rule requires that selected livestock operations report CO₂e, CH₄, and N₂O GHG emissions caused by their animal production and MMSs. This paper included the details of the rule applicability and GHG emissions estimation requirements for reporting the CH₄, N₂O, and CO₂e emissions. Additionally, this paper also discusses the various reporting requirements of the rule. The owners or operators of livestock facilities with MMSs must determine the rule applicability to their facilities and confirm the reporting requirements with the USEPA.
