How Argus assesses environmental markets
-
Market-reflective design
Designed to reflect how North American environmental markets trade, aligned to standard currencies, locations and volume units. -
Broad market participation
Informed by data from producers, consumers and intermediaries across North American environmental markets. -
Data hierarchy and weighting
Transactions take precedence over bids and offers, which take precedence over other market data, to ensure reliable assessments. -
Transaction verification
Data is verified for price, volume, specification and counterparty, with anomalous transactions subject to further scrutiny. -
Assessment judgment
When transaction data is insufficient, reporters apply judgment using bids, offers, spreads and fundamental market information.
