Pentagon mandates greenhouse gas emissions disclosure for defense contractors
The Defense Department issued a final rule amending the DFARS to require disclosure of greenhouse gas emissions by contractors as mandated by the National Defense Authorization Act for Fiscal Year 2024. The change takes effect immediately and applies to all new defense acquisitions governed by the supplement.
indianexpress.comThe Defense Department published a final rule May 7, 2026, that adds a greenhouse gas emissions disclosure requirement to the Defense Federal Acquisition Regulation Supplement.
The rule implements Section 1030 of the National Defense Authorization Act for Fiscal Year 2024 and carries the regulation identifier number 0750-AM18. It applies to all contractors submitting offers or entering contracts subject to DFARS, which governs more than $400 billion in annual Department of Defense procurement.
Prior to the rule, DFARS contained no systematic requirement for contractors to disclose their greenhouse gas emissions inventory. The new state requires disclosure as a condition of contract award and administration. The rule became effective on the day of publication, May 7, 2026, per the Federal Register notice signed by President Donald Trump.
Contractors must now compile and submit emissions data using protocols established in the NDAA provision, triggering updates to solicitation provisions and contract clauses within the next procurement cycle. Contracting officers will incorporate the new DFARS clause into awards, creating a compliance deadline that aligns with existing bid submission timelines.
The Defense Acquisition Regulations System will next update online DFARS resources and training materials for acquisition personnel. Congress retains oversight authority through the annual NDAA process and can amend or repeal the underlying statutory mandate in future defense authorization bills.
This rule represents the first formal integration of the 2024 NDAA greenhouse gas disclosure mandate into the DFARS. The NDAA for Fiscal Year 2024 directed the Pentagon to establish such a requirement within 18 months of enactment.
