Greenhouse Gas Management Institute (GHGMI) · Online, United States
The carbon accountant's professional school: a nonprofit institute that does nothing but greenhouse gas measurement, reporting and verification, whose diploma requires passing six assessed components — organizational accounting, project-level accounting, IPCC cross-cutting issues and electives — typically over six to nine months. Exam-based and genuinely technical, this is the deep alternative to a two-hour standards webinar, and the credential inventory practitioners cite to each other.
Fees and deadlines change every year: always confirm them on the official page before applying.
