Summary
The Greenhouse Gas Protocol – the global gold standard for measuring corporate emissions – is under review, and the proposed changes could dramatically reshape how clean energy is bought, sold, and reported. New draft rules are expected by the end of the year.
What changes could we see? And how will they impact the energy transition? To find out, Sylvia Leyva Martinez, principal analyst at Wood Mackenzie covering solar markets, speaks with Lee Taylor, CEO of Resurety – a leading provider of data and analytics for clean energy buyers. Lee has spent over a decade helping companies understand not just how to procure renewables, but how to do so with real carbon impact.
Together, they explore what’s changing in Scope 2 emissions accounting, why location and timing of energy use now matter more than ever, and how voluntary clean power markets might evolve. They break down complex concepts like emissionality, 24/7 procurement, and consequential accounting – and what these mean for corporate net-zero strategies, PPA structures, and the future of Renewable Energy Certificates.
If your business buys clean electricity or reports against Scope 2, this is essential listening.
Plus, Taylor shares his advice for buyers and developers navigating the shifting landscape, and explains why the next six months will be key in shaping rules that will define voluntary climate leadership in the coming years.

| 1:19.1 | A couple of weeks before the release of this episode and a few days before we recorded it, |
| 1:24.6 | the Clean Energy Buyers Association and ACOR, the American Council on Renewable |
| 1:29.4 | Energy, both sent a letter to the GHG Protocol's Independent Standards Board, urging them to |
| 1:36.0 | keep some of the key rules that are being revised. |
| 1:39.1 | Over the last decade, close to 200 gigawatts of clean energy globally has been built tied to contracts with |
| 1:47.3 | voluntary buyers who are pursuing those procurements for purposes of reducing their carbon footprint. |
| 1:53.6 | In the U.S. alone, I think we had close to 100 gigawatts contracted in the past decade since the |
| 1:58.1 | creation of this protocol with almost none prior to 2015. |
| 2:01.8 | So it's been a fairly dramatic change. |
| 2:03.7 | It's been highly successful in driving voluntary demand. |
