AIG has been handed a petition by anti-Adani activists, demanding the US insurer declare that it is not providing insurance for the Carmichael coalmine project in central Queensland.

An AIG spokeswoman told insuranceNEWS.com.au the insurer has no comment on the petition or protests that were staged outside its offices in Sydney, Melbourne and Brisbane.

The protests took place last Thursday as US-registered activist group SumOfUs delivered the 1300-page petition containing more than 109,000 signatures to the insurer’s Sydney office.

Campaign Manager Nick Haines says a group of policy and private security personnel were stationed outside the office when he arrived with other protesters.

They were able to pass the petition to a building manager who said he would hand it to the company.

“We haven’t heard from AIG,” Mr Haines told insuranceNEWS.com.au. “They have been very quiet. They may be involved already [with Adani] or they may not be, but they have not confirmed either way.”

A list compiled by climate advocacy group Market Forces puts at 14 the number of insurers who have publicly ruled out any involvement with the Adani project. QBE and Suncorp are on the list but Australia’s largest locally owned insurer IAG is not — although it has confirmed to insuranceNEWS.com.au it is not involved with Adani.

Environmental campaigners have vowed to continue fighting against the Carmichael mine. They say the mine will worsen the already fragile Great Barrier Reef ecosystem and increase fossil fuel pollution.

“AIG is active in Australia and so it’s one of the companies we believe is at risk from providing insurance for this project. That’s why we are calling on them today [to act],” Market Forces campaigner Pablo Brait told insuranceNEWS.com.au.

“Fourteen other companies have already made this commitment, including the Australian insurers.”

An Adani spokesman maintains the identity of the insurers for the project is confidential.

“Details on insurance providers for the Carmichael Project are commercial in confidence,” the spokesman told insuranceNEWS.com.au.

“However, we have the necessary insurance requirements in place consistent with our construction activities.”
