Platts launches Soil Carbon ACCU price assessment

Platts, part of S&P Global Commodity Insights, has launched a price assessment for Australian Carbon Credit Units (ACCUs) generated from Soil Carbon methods, effective May 5.

ACCUs are issued by Australia's Clean Energy Regulator (CER) to carbon project developers based on legislated methodologies. They are used to offset emissions by liable entities under Australia's Safeguard Mechanism scheme and can also be used to offset additional emissions on a voluntary basis.

Each ACCU represents one metric ton of CO2 equivalent.

The launch follows a proposal(opens in a new tab) on March 24 and a decision(opens in a new tab) on April 7.

The daily spot assessment will provide more transparency on growing activity in the Soil Carbon segment of the ACCU market.

This assessment reflects the price of credits that are generated by projects storing additional carbon in agricultural soil. Examples include improving fertilizer application, reestablishing pasture or modifying grazing practices as specified by the CER.

The specifications of the new price assessment are as follows:

  • Volume: 500-50,000 mtCO2e
  • Currency: Australian dollar
  • Unit of measurement: Australian dollar per metric ton of CO2 equivalent (A$/mtCO2e)
  • Delivery: Spot market
  • Frequency: Daily
  • Time stamp: 16:30 Melbourne/Sydney/Canberra time
  • Platts publishing calendar: Asia-Pacific carbon calendar

A monthly average is now also published for the assessment.

The new assessment and monthly average are as follows:
