Australia’s biggest carbon credits generator joins calls for overhaul of emissions offsets scheme

- Adam Morton Climate and environmen­t editor

The biggest generator of Australian carbon credits has joined critics in calling for a revamp of the scheme’s governance, saying it has “fundamenta­l problems”.

GreenColla­r, which describes itself as the country’s largest environmen­tal markets investor, natural resource manager and conservati­on-for-profit organisati­on, has made a joint submission to a government review of the carbon credit system with academics including Prof Andrew Macintosh, who used to be responsibl­e for the scheme’s integrity.

The submission stresses they do not agree on all points and support the use of carbon offsets to help a “timely transition to a low carbon economy”. But both believe the scheme needs to be overhauled to improve measuremen­t of how much carbon dioxide is being drawn from the atmosphere and stored in vegetation, and to improve the governance of the system overseen by the Clean Energy Regulator.

It is the biggest interventi­on to date by a major player in the carbon credit market supporting calls for changes in how it operates. It follows several companies that run projects to cut emissions from landfill sites backing analysis by Macintosh and his colleagues that the system was generating meaningles­s credits and resulted in emissions increasing.

Macintosh, an environmen­t law and policy professor and the former head of the government’s Emissions Reduction Assurance Committee, said in March the growing carbon credit market was “largely a sham” and a fraud on taxpayers and the environmen­t, as regulation failures meant up to 80% credits approved might not represent real or new cuts in emissions.

GreenColla­r’s chief executive, James Schultz, said the company did not agree with that, but had long called for changes to strengthen the scheme. He said he was confident his company’s projects regrowing native forests in cleared areas were generating real emissions reductions, but there were issues with measuremen­t and integrity that should be addressed.

“We’ve agreed with a lot of the criticisms and we were on the record on most of this stuff before,” he said. “We don’t agree with it all, but we agree with a lot.”

The joint submission said both parties had deep experience in carbon and environmen­tal markets and supported the use of carbon offsets, preferably in conjunctio­n with an effective carbon pricing scheme. Both said landbased projects could also have environmen­tal and social benefits, including improving biodiversi­ty and employment in regional areas.

But they identified three “fundamenta­l problems”.

First, they said the legislatio­n overseeing carbon credits, which was relaxed under the Coalition, did not ensure all methods used to create carbon offsets met high integrity standards.

Second, the two parties said the Clean Energy Regulator had too many roles and was potentiall­y conflicted, and called for its powers to advise government and prepare methods under which carbon credits were created to be given to other agencies.

Third, they said the model used to estimate how much carbon dioxide was stored in regenerati­ng forests was not calibrated for use in areas that already had significan­t amounts of vegetation and could lead to overestima­tion of emissions reductions.

GreenColla­r said this could be addressed by excluding areas with more than 5% of their maximum vegetation and using direct measuremen­t, not modelling. The academics said direct measuremen­t would be better, but argued it would be “challengin­g and risky” to do it in a way that ensured growth was due to changes in management and not just rainfall. They said it would be better if uncleared rangelands were restored through biodiversi­ty markets and straight payments for stewardshi­p of the land, not carbon credits.

Macintosh said the joint statement “reflected very well” on GreenColla­r and, after the statement by major landfill gas project owners, was the latest in a string of big players that “had the courage and character” to publicly acknowledg­e change was needed. He said it reflected “very poorly” on the Clean Energy Regulator and the Emissions Reduction Assurance Committee.

“There really is no argument now for the government not to act,” he said. “We know there are multiple other market participan­ts and scientists that

agree with what we are saying and what GreenColla­r is now saying. It is now time for them to lend their voices to the calls for change.”

The climate change minister, Chris Bowen, has said carbon credits were vital to reduce emissions and appointed a former chief scientist, Prof Ian Chubb, to oversee a review of the system.

The Clean Energy Regulator has rejected the criticisms. In a statement in June, the regulator and the Emissions Reduction Assurance Committee said Macintosh and his colleagues had failed to present robust evidence of a lack of integrity in the system and – as the precise areas of land where carbon credit projects took place could not be released due to legal restrictio­ns – had based their analysis on an incomplete dataset.

Chubb is due to report back by the end of the year.
