A proposed update to the Greenhouse Gas Protocol's Scope 2 accounting rules would require companies to match clean energy usage by hour and grid, replacing the current annual and regional approach. This change risks invalidating most existing renewable energy certifications and could significantly lower sustainability scores, affecting market access for major global companies.

This Wire brief sits within Fusion42's coverage of Clean Energy and Carbon Tech.

◆ The Wire takeaway

You face a forced reset of clean energy accounting rules that will slash sustainability scores for many companies outside a few tech giants. Your route to compliance and market access just narrowed sharply with this clock-tied and grid-tied method.
