With news today that RET uncertainty has forced Meridian Energy Australia to abandon its Burdekin Hydro project in Northern Queensland, Australian Greens Leader Christine Milne, who is in Lima, says the Abbott government's duplicity has been exposed.

"Julie Bishop is over here in Lima bragging about ARENA and the Renewable Energy Target, but even as she speaks her government's attack on the RET is damaging jobs, investment, and efforts to cut pollution," said Senator Milne.

Australian Greens Leader Christine Milne says the Abbott government has cemented Australia's reputation as a climate free loader by attempting to rort emissions accounting rules.

"Before Foreign Minister Julie Bishop left Australia she said one of her reasons for coming to the climate talks in Lima was to change the accounting rules that relate to Australia achieving its pollution reduction target," Greens Leader Christine Milne said.

Speaking from Lima, Greens Leader Senator Christine Milne says Australia is doing everything it can to obstruct progress at the UN climate talks.

"Australia continues to be the chief obstructer in these climate talks, making efforts to remove the most basic things from the draft text which have already been agreed to, like a commitment to global solidarity and long term temperature limits," Senator Milne said.
