Labor MPs with emissions-intensive industries like steel in their electorates will meet Climate Change Minister Greg Combet today to push for the concessions.
The calls come after the Government announced ithopes to unveil the full details of its carbon tax and trading scheme on Sunday.
The Government has announced petrol will not be taxed for householders, tradespeople and some small businesses.
The Transport Workers Union is demanding truck drivers get help too and Labor Senator Glenn Sterle has backed the calls.
"[We are] shoulder to shoulder with Australia's truckies to make sure that our hard-working men and women in the transport industries are fully protected and compensated for their efforts," he said.
Before the price, compensation, and renewable energy funding is announced on Sunday, there will be at least one more meeting of the committee and another meeting of Cabinet.
The Federal Government has been working with the Greens and two independent MPs since late last year to find a consensus on the way to price carbon.
Mr Combet says while there are still some details to be discussed this week, the Government is confident enough to announce "all of the package" on Sunday.
"It will be very important for the future of the country," he said.
"It will cut out pollution while still allowing strong economic growth and jobs growth and growth in living standards in the future, and it'll help drive the transformation of the economy to a clean energy future."
Greens deputy leader and Multi-Party Committee member Christine Milne is just relieved a date has been set.
"The overwhelming majority of Australians want action on climate change. They need to be convinced though, that this is the right action on climate change and that's why getting the detail out will be so important," she said.
The relief is also evident among Government backbenchers. The announcement is carefully timed ahead of the five week mid-winter break, giving Labor MPs time and details to sell to their electorates.
As one said to AM, it makes them a lot more positive about what will be a tough fight.
Others are more pessimistic, telling AM it just means the debate will enter a different phase and things probably will not improve for the Government until the scheme gets through Parliament, the budget returns to surplus, and the focus can shift to jobs and training.
Others are hopeful the long-awaited details will blunt the Coalition's attack.
But the Opposition's climate spokesman, Greg Hunt, says the timing of the announcement shows the Prime Minister is running away from Parliamentary scrutiny.
"They already have the details of this tax. They already have an agreement. They already have everything that needs to be tabled before the Parliament this week. If something can be done before the Parliament, it should be done," he said.
Government MPs have become increasingly uneasy at the drip-feed of information about the carbon price plan, worried it invites more questions than answers.
On ABC TV's 7.30 program, Opposition Leader Tony Abbott was claiming credit for one of those selective leaks - the decision to exempt fuel for motorists, small businesses and light commercial vehicles.
"Do you really think that petrol would be excluded had I not been campaigning hard to protect the motorists of Australia?" Mr Abbott said
