Abstract: An institutionally-focused, neutral auction platform is provided that may be utilized for both the primary and secondary trading of environmental commodities and instruments. The auction platform may perform an on-boarding process for auction participants. Thereafter, the auction platform initiates an auction event, in response to a request by an auctioner, based on an identified block of environmental commodities. The auction platform may also receive an indication of financial security from one or more of the auction participants. A winning bidder may then be selected based on auctioner-defined parameters. In certain embodiments, the auction platform may also perform a settlement function for the auctioner and winning bidder relating to the delivery of, and payment for, the identified block of environmental commodities. Various other services and processes may also be provided by the auction platform.
