Price assessment details

What are the advantages of the Argus seasonal NOx allowance price assessments?

With extensive experience in pricing NOx and SO2 allowances in North America, Argus provides the market with a regular and reliable price benchmark for trading.

Because of the more-stringent nature of the new group 3 NOx program, allowance prices are expected to remain relatively high, making it more important to have an independent price reference. As well as publishing the price assessments, Argus’ daily news and market analysis keeps you updated on surrounding developments and the latest regulatory changes.

Argus collects market information, including trades, bids and offers, from a broad range of market participants to inform the assessment.

How is this assessment used?

These prices are used by power plant operators and referred to by coal producers. Traders involved in North American environmental markets also benefit from the independent price and view of the markets.
