The reference guide is explicit that if you are purchasing off-site renewable energy for fuels combusted on site (Scope 1 emissions), it needs to be done via carbon offsets ("Green-e Climate or equivalent"), not RECs.

However, the Green Power Provider Summary table in form EAc4 v3.0 only lists 'Purchase Types' for electricity purchase / RECs:

"Green-e certified power provider
"Green-e accredited utility program
"Green-e accredited tradable renewable certificates
"Green-e equivalent"

(It's clear from the reference guide that "Green-e equivalent" refers to an alternate certification for renewable power, not the Green-e Climate certification for carbon offsets.)

How are we to document purchases of carbon offsets to cover Scope 1 fuel combustion?
