The Tasmanian Government has released a climate change strategy aimed at 100 percent renewable power usage by 2020.

The Climate Smart Tasmania plan includes energy reduction targets across government, land use, infrastructure, transport and waste systems.

The Climate Change Minister, Cassy O'Connor, says its the most comprehensive plan by any Australian Government to reduce carbon emissions as well as adapt to a changing climate.

The strategy sets a new interim 2020 target to reduce carbon emissions to 35 percent below 1990 levels.

Ms O'Connor says its about showing leadership on climate change.

"We now have in Australia a climate denialist Government that is taking us backwards on climate change" she said.

"Tasmania here has extraordinary advantages with our Hydro power, with the carbon in our forests and we do need to show leadership; it's also the economically sensible thing to do."

Opposition energy spokesman Matthew Groom accused the minister of engaging in spin over substance.

"Here we are after the parliament has risen, on the eve of an election presenting a climate change strategy that is largely going to be the task for a future government," he said.

Mr Groom cast doubt on the Government's claims about reduced emissions.

"What has been the emissions profile of Tasmania under a Greens climate change minister?"

"That Ms O'Connor wont' tell you the answer to and I suspect the reason she won't tell you is the fact that they have gone up."
