On December 1, REsurety and WattTime will launch a calculator to help organizations understand how their current renewable claims and goals may be impacted by proposed changes to Scope 2 energy procurement methodology.
Output from forthcoming REsurety & WattTime calculator tool. Will your current procurement cover your load under proposed rule updates by the GHGP?
The Greenhouse Gas Protocol (GHGP) writes the rules that govern close to 97% of the corporate world’s clean energy purchasing and reporting. For the first time in ten years, they are opening the books for a rewrite.
Two options are on the table, and the public is invited to share their opinion on both before December 19. But the two options offer wildly different views into the future: one that is focused on making sure we can track the exact source of the energy being sent to power corporate headquarters (hourly matching), and one that is focused on making sure corporations have the most impact with the dollars they spend (consequential accounting).
Download the white paper to find out. Check back on December 1 for access to the full calculator so you can see plan for future procurement, no matter the outcome of the GHGP’s vote.
Using the calculator tool, this case study walks through a real-world example of CleanCo’s energy future: budget, impact, and strategy.
