Granularity Matters: Filling the data gap for granular carbon accounting

Gain access to groundbreaking insights on sustainable procurement and hourly carbon accounting.

Explore a new way to calculate hourly residual energy mix in the AIB region for more accurate Scope 2 carbon accounting data We examine current EAC system limitations, propose an hourly residual mix methodology, and evaluate its impact on market-based Scope 2 accounting.

Moving from annual to hourly data reveals discrepancies between claimed renewable energy consumption and actual generation patterns, resulting in a number of claimed annual certificates that cannot be matched on an hourly level. Join us in pioneering the way for granular accounting and collaboration in the sustainability and carbon accounting sector.

Some Key Insights include:

Limited data on cross-border EACs movement leads to a lack of clear oversight on how certificate trading aligns with actual flows of electricity.

An annual EAC system fails to reveal the mismatch between renewable electricity consumption claims and actual renewable generation.

An analysis of Scope 2 market-based accounting reveals higher carbon emissions with hourly residual mix than with hourly grid emission factors.
