The rally will co-incide with World Environment Day, and the vote of the Federal Government's emissions trading scheme which is scheduled to be held today.

BREAZE, in a letter to Ms King, has asked her to oppose the ETS legislation in its present form because it is not tough enough on big polluters.

"The primary flaw in the legislation is that it locks Australia into at least 10 years of inaction on greenhouse gas reduction and ignores the advantages to Australia (to have) a swift move to a low carbon economy," the letter

read.

"It places the interests of a small and vocal group of industries above those of our citizens."

BREAZE said its concerns with the legislation are that the proposed five to 25 per cent reduction in emissions should be higher, compensation and free permits given to polluters removed incentives for investment in renewable

energy, and businesses and households who go green will subsidise coal fired power stations in Victoria's East.

Ms King said the government was responding to requests from groups like BREAZE to act on climate change.

The legislation was developed with community consultation, and its rejection would doom a "significant" environmental and economic reform, she said.

"BREAZE has called in the past for the introduction of a carbon pollution reduction scheme and that is what the government plans to do," Ms King said.

"Those who think that by voting this legislation down there will be a better opportunity to revisit targets to redesign the scheme at some later date have simply failed to read the politics of this debate.

"I believe it is the best option and will vote for it in the house (today)."

The BREAZE protest will be held this Friday at the corner of Sturt and Lydiard streets.
