Webinar Recap: Exploring the Limits of Hourly Matching in Scope 2 Reporting

 

The title page of the Webinar: Limitations of Hourly Matching Claims for Scope 2 Reporting. It features the profile shots of the moderator, Miranda Ballentine, and the co-authors, Michael Gillenwater and Michael Leggett, plus their titles and organizations. Ballentine is the Senior Advisor to Green Strategies, Inc. Gillenwater is the Executive Director and Dean of the Greenhouse Gas Management Institute. And Leggett is the Co-Founder and CPO of Ever.green.Is hourly matching the future of Scope 2 reporting—or a well-intentioned detour?

That’s the provocative question that anchored two webinars, featuring a candid conversation between Miranda Ballentine (Senior Advisor at Green Strategies, Inc.)  and co-authors Michael Gillenwater (GHGMI Executive Director and Dean) and Michael Leggett (Ever.green Co-Founder and CPO). Together, they unpacked the ideas presented in their newly published essay, Limitations of Hourly Matching Claims for Scope 2 Reporting.

The panel explored how companies make claims about their clean energy purchases and the implications of shifting from annual to more granular hourly accounting methods. They tackled essential questions, including:

  • Has the voluntary clean energy market effectively driven new clean energy development?
  • How do geography and grid impacts shape credible energy claims?
  • What tradeoffs come with hourly vs. annual matching in practice?

The discussion was rich with insights for sustainability professionals, Scope 2 practitioners, and climate policy thinkers alike. The trio then hosted a Q&A follow-up session to answer questions from the audience.
