Latest Trends in Hourly CO₂ Emission Evaluation for Electricity Sector Under Scope 2 Revision

In today's rapidly evolving energy landscape, understanding hourly CO₂ emissions is becoming increasingly crucial for businesses and organizations involved in energy procurement and sustainability initiatives. The Japan Planning Institute (JPI) is set to host a seminar on August 25, 2026, featuring the expert insights of Mr. Masataka Mizutani, a chief researcher from the Carbon Neutral Technology Center of the General Incorporated Foundation for Energy Comprehensive Engineering Research. This seminar will delve into the latest developments in evaluating hourly CO₂ emissions in anticipation of the Scope 2 revisions under the GHG Protocol.

As the focus on sustainability intensifies and the integration of renewable energy sources expands, the structure of power supply has dramatically changed, leading to variations in emission factors based on time and geography. The traditional methods of annual average evaluation have proven inadequate, thereby driving increased interest in time-sensitive assessments. The discussions surrounding Scope 2 revisions will highlight critical aspects such as hourly matching and supply availability boundaries, which could significantly impact corporate strategies.

What to Expect from the Seminar

Attendees can look forward to acquiring practical knowledge and insights, including:

- Designing criteria for renewable energy procurement based on hourly matching
- CO₂ calculation logic that considers hourly factors and integrates AEF (Average Emission Factor) and MEF (Marginal Emission Factor)
- Scenarios for optimizing emissions through EV charging and battery storage

The seminar caters to various sectors, including:

- Energy Procurement Units
- Sustainability and Decarbonization Departments
- Corporate Planning and Investment Assessment Units
- Power and Infrastructure Companies
