The research suggests that mandatory hourly matching inadvertently stifles progress by prioritizing accounting wins over real-world climate impact.

Impact Matters More Than Optics:
High-rigor papers highlight that current proposals ignore the causality of emissions, focusing instead on simple timestamp synchronization rather than actual carbon displacement.

Grid Dynamics Are Complex:
Proposed hourly matching does not account for the marginal emissions of the grid, meaning it omits the impacts of nearby transmission, demand, and the power that is actually being displaced by new clean energy.

All Power Markets Are Not Alike:
The impact of hourly matching is heavily reliant on location, regulation, and spot market development across power market regions. What might work in one developed market won’t work in others.

Everyday Businesses are Left Behind:
The proposed hourly mandate excludes smaller corporate actors from the clean energy market due to prohibitive complexity and costs.

What the Research Recommends Instead 

The entirety of the research reviewed advocates for significant changes to current annual matching standards. However, instead of rigid temporal matching, the high-rigor consensus points toward flexible, impact-driven alternatives that could accompany optional hourly matching:

Consequential Accounting:
Measuring the actual carbon displaced on the grid, shifting toward impact-based accounting.

Quantifiable Additionality:
Prioritizing investments that bring new clean energy to the grid.

Flexible Impact Matching:
Encouraging procurement that targets high-emissions hours or locations without the full, restrictive mandate of hourly matching.
