Australian Greens Leader Bob Brown today condemned the government-business agenda to wreck environmental laws.

"There is no evidence that delays are jeopardising the viability of any projects. The boom is still booming. In fact, no major resource extraction projects have been refused under the Environment Protection and Biodiversity Conservation Act," Senator Brown said.

Today's call to strip down environmental processes and fast track everything - mining mega-developments to shopping centres - is a war on the Australian people's quality of life and the environment by the big end of town, Greens Leader Bob Brown said today.

Australian Greens Leader Bob Brown has rebuffed Cardinal Pell's Easter attack on the Greens as not very Christian.

"I hope the good Cardinal reads The Australian's Easter editorial noting comments from Melbourne's Catholic Archbishop Denis Hart and calling for ‘forgiveness, atonement, hope, tolerance and generosity'. Somewhere up the Hume Highway as you get towards Archbishop Pell these sound religious values tend to evaporate," Senator Brown said today in Hobart.

Australian Greens Leader Bob Brown has called on Treasurer Wayne Swan to reverse the government's doctrinaire insistence on a surplus in the May budget.

"The cuts affecting art galleries, environmental well-being and a growing range of public services are not just unnecessary, they threaten Australia's small business economy and jobs in the public and private sector," Senator Brown said today in Hobart.

"A growing number of experienced economists are saying 'wrong way, go back' to the Treasurer.

"This is the third Global Greens Congress, after the conference in Canberra in 2001 established the process, and is the first to be held in Africa. The second Congress was held in Sao Paolo, Brazil, in 2008."
