The senators, including the Nationals' Barnaby Joyce, suggest that if Australia's emissions are allowed to grow, it would stop industry going overseas where environmental regulations might be weaker.

"Where it helps reduce global greenhouse gas emissions, growth in domestic emissions as a result of growth in economic activity should be encouraged, not constrained by any Australian emissions trading scheme," a report by the MPs says.

The report was tabled yesterday by the Coalition-dominated Senate Select Committee on Fuel and Energy, which has been reviewing the Federal Government's emissions trading plans.

Labor senators on the committee did not endorse the position, but did recommend the Government pursue a "wide range of complementary measures" as well as emissions trading.

Industry is continuing to pressure the Government for further changes to its emissions trading plans after it announced on Monday a one-year delay to the scheme and extra help for trade-exposed industries.

The Australian Chamber of Commerce and Industry yesterday called for a delay in legislation for the scheme, despite the Government's insistence that it will introduce the proposed legislation next week so it would be debated in June.

Climate Change Minister Penny Wong said the bill needed to be passed this year, despite the scheme's starting date being delayed until mid-2011, as it would send investors a signal to begin investing in green industries.

The Coalition is calling for the bill to be delayed until after international climate negotiations in Copenhagen in December.

Parliamentary secretary for climate change Greg Combet will meet representatives of major coal companies, including BHP, Rio, Xstrata, Anglo and Centennial Coal, in Newcastle today.

The industry representatives will present research they have commissioned, outlining potential job losses and mine closures in the industry.

Mr Combet is unlikely to present the industry with more compensation at the meeting, but sources believe the Government is prepared to move further on industry assistance.

However, the Government is set to make a concession to the landfill industry by rewriting the reporting conditions for the industry.

The landfill sector has long complained the initial reporting regulation under the scheme unfairly charged too much carbon liability to the industry. The new regulations were finalised by the Department of Climate Change yesterday and sent to Senator Wong's office to be ticked off.
