UPDATE: Read the details of the carbon price and clean energy package here.

Pollution from burning coal, oil and gas is driving a climate crisis, making our world more dangerous, increasing prices of food and water and jeopardising our way of life.

But if we cut pollution and invest properly in the clean alternatives, we can build a healthier, cleaner, more secure economy and community for all of us.

Why do we need a carbon tax?

Senator Bob Brown and Senator Rachel Siewert urge state and federal leaders to boost mental health services and work towards a national, universal public dental care scheme.

Senator Brown also vows to take on Rio Tinto, whose profit bonanza will benefit its more than 70-percent foreign shareholders, and other heavyweights as companies prepare to fight efforts to develop an alternative to coal and the Greens’ push to put an effective price on carbon.
