Australian Carbon Credit Unit (ACCU) supply rose in February on the back of strong issuances from vegetation methodologies, with environmental market investor GreenCollar receiving the highest volume during the month.
A total of 1.24mn ACCUs were issued in February, up from 834,541 in January, according to data released by the Clean Energy Regulator (CER). Vegetation methods accounted for 1.11mn, or nearly 90pc of the total, up from 60pc in January and the highest share over reported periods in recent years.
The CER previously released fortnight data but switched to monthly figures in 2025, with no comparable monthly data before then. But quarterly data from as early 2019 show the highest share of vegetation issuances at nearly 78pc in the fourth quarter of 2022 (see chart).
GreenCollar's subsidiary Terra Carbon received 303,681 ACCUs last month from human-induced regeneration (HIR) and avoided deforestation (AD) methods, by far the highest volume among individual developers.
ACCUs from waste methods made up just 5pc of all issuances in February, at 61,642 units, the lowest share over reported periods in recent years. The lowest share for any quarter since 2019 was around 13pc in the second quarter of 2020.
CER's latest data show 2.07mn of issuances in the first two months of 2025. The regulator recently said it expects to issue between 19mn-24mn ACCUs in 2025, up from the record high of 18.78mn in 2024.
ACCU generic (No AD) spot prices started February just above A$35 ($22.24) and ended the month at A$33.50, given lower ACCU buying interest from safeguard companies and strong issuances of safeguard mechanism credit units.
