This is the homepage for the current versions of the methodologies that allow WattCarbon to create EACs for clean energy resources. Each methodology category is contained in a separate folder.
The OpenEAC Alliance is a volunteer organization comprised of individuals and organizations with experience developing measurement and verification techniques. Each methodology is reviewed by members of the OpenEAC Alliance and each change to an approved methodology will require notification of all reviewers.
For meeting updates and up-to-date communication, see our substack.

Individual methodologies are added by Request. New methodologies should be in a google doc that allows for public comment. The link should then be shared with one of the OpenEAC Alliance maintainers (such as mcgee@wattcarbon.com) so that it can be added to the list of methodologies.
The approval process proceeds in several steps:
