The U.S. EPA has released a new Status Report Primer for recipients of Climate Pollution Reduction Grants (CPRG) planning funds, confirming that a Status Report is required at the end of the four-year grant period.
The primer outlines EPA’s expectations for the report and offers recommendations on how jurisdictions can structure it and track implementation progress under their Comprehensive Climate Action Plans (CCAPs).
Consistent with earlier CPRG guidance, EPA confirms that Status Reports must include updates on several core CCAP elements, plus one additional requirement, including:
Required
Implementation status of greenhouse gas (GHG) reduction measures
Metrics tracking and quantified results for completed measures
Review of authority to implement measures
Intersection with other funding opportunities
Workforce planning progress
Updated benefits analysis
Additional Requirement: Identify and outline next steps for CCAP implementation, including near-term projects, timelines, milestones, and associated budget and staffing needs
Encouraged
GHG inventory updates
GHG emissions projections and reductions
Updates to GHG reduction targets
Implementation narratives providing additional detail on progress
Updated cost analysis
Public outreach related to CCAP implementation
These components largely reflect the reporting expectations outlined in the original 2023 CPRG planning grant guidance, which anticipated that the Status Report would provide updates on CCAP implementation and identify next steps.
While the core requirements remain largely consistent with earlier guidance, the primer provides additional detail on how grantees should approach the report, including:
Clarification that updates to GHG inventories and emissions projections are encouraged but optional.
The previously required LIDAC benefits analysis is no longer required for the Status Report.
Recommended approaches for tracking implementation progress.
Grantees must report quantified emissions reductions for fully implemented GHG reduction measures using the metrics in their CCAP. Reporting for partially implemented or under-development measures is encouraged but not required. Grantees are also encouraged to update estimated or actual GHG reductions for any measures as needed.
Guidance on updating benefits analysis and co-pollutant reductions
Expanded discussion of funding alignment, workforce needs, and implementation barriers
The Primer signals that jurisdictions should establish processes to track implementation progress and measurable outcomes throughout the grant period, rather than waiting until the end to compile reporting materials.
EPA emphasizes that the report should be used to communicate progress, adjust priorities, and identify resources needed to sustain climate action beyond the CPRG planning grant period.
Reduction measures will be at varying stages of implementation, making narrative updates essential to clearly communicate progress. All measures must be addressed in the Status Report, including those with limited or no progress, along with explanations and next steps.
