Hosting Online Seminar on July 8 (Wed): 'Corporate PPAs Amid Upcoming GHG Protocol Revisions: How to Choose the Right Approach for Your Company? – Comparing and Utilizing Virtual PPAs and Environmental Attribute Certificates'

Yachiyo Engineering Co., Ltd. (Head Office: Taito-ku, Tokyo; President and CEO: Tsutomu Takahashi) will host an online seminar titled 'Corporate PPAs Amid Upcoming GHG Protocol Revisions: How to Choose the Right Approach for Your Company? – Comparing and Utilizing Virtual PPAs and Environmental Attribute Certificates' on Wednesday, July 8.

'We want to increase our renewable energy ratio to reduce Scope 2 emissions, but there are so many types of PPAs (Power Purchase Agreements) that we can't determine which one suits our company.'

'We can't assess the risks of long-term contracts, so internal approvals are stalled.'

We frequently hear such concerns from companies engaged in renewable energy procurement.

As decarbonization becomes a requirement across entire supply chains, Corporate PPAs—which demonstrate additionality by driving investment in new renewable energy facilities—are gaining attention. Additionally, the GHG Protocol (Scope 2) is currently under revision, with new topics such as 'hourly matching' (time-based alignment of supply and demand) emerging. Although still in draft form, the fundamentals of renewable energy procurement are shifting, increasing the importance of correctly evaluating PPAs and other available options.

This seminar will unpack the basics of diverse PPA models and compare them with alternative and complementary instruments such as non-fossil fuel certificates and green power certificates, from the unique perspective of a certificate-issuing organization.

Furthermore, we will introduce key points for building a renewable energy procurement portfolio, incorporating the latest trends in the rapidly evolving renewable market. Participants will gain practical comparison criteria and risk assessment frameworks that can be directly used in internal discussions. We encourage environmental officers actively considering PPA adoption and executives seeking optimal strategies to attend.

This seminar is recommended for company representatives who face the following challenges:

- Wanting to compare and organize renewable energy procurement options to reduce Scope 2 emissions - Seeking to understand the differences and appropriate uses of PPAs versus environmental attribute certificates - Interested in adopting PPAs but facing challenges regarding long-term contract risks and internal approval processes - Already exploring renewable energy procurement but uncertain about the optimal combination (portfolio) for their company
