The Greens and Labor have called on the state government to prioritise the implementation of a container refund scheme in Tasmania.
CRSs operate in other Australian jurisdictions with evidence they reduce littering and it was announced during budget hearings last year the government had committed to introducing a CRS by 2022.
Greens environment spokeswoman Rosalie Woodruff said, while most other states have slowly committed and rolled out this critical environmental policy, Tasmania for too long had refused to act.
"While we are pleased the Liberals finally bowed to the evidence and community will, there has been no concrete evidence of actions started, and there is no reason for the delay," Ms Woodruff said.
"For the last five years the Greens have been asking for the Hodgman government to commit to implementing a container deposit scheme. It should be in place now."
Ms Woodruff said stakeholders such as Boomerang Alliance, Clean Up Australia, scout groups and environmental groups, who have long called for a cash for containers scheme, should be consulted in the development of the scheme.
"These are the people who should be consulted, not industries who have been keeping government brakes on for years," she said.
"It is important the financial benefits of the scheme flow to communities, not to large corporations who have been actively lobbying to stall container deposit schemes for as long as possible."
Tasmanian Labor senator Helen Polley said the state government needed to work harder to implement the scheme and release more detail on how it would operate.
"The Hodgman government has said it intends to introduce a CRS in Tasmania by 2022, but they have not provided any detail around how the system would work or what obligations would be placed on producers and what opportunities consumers would have," Senator Polley said.
"A CRS has been in place in South Australia since 1977. It is 2020 and Tasmania still doesn't have a scheme."
Environment Minister Peter Gutwein said work had commenced on developing an appropriate CRS model for consultation with the community, businesses and industry.
"The 2022 implementation target for the CRS gives us the time learn from schemes operating in other jurisdictions and get the model right so that all Tasmanians can share in the benefits of a contemporary CRS," Mr Gutwein said.
"Specialist advice from government and industry, as well the establishment of an expert reference group, will be critical to the scheme's success."
