Plan will not cut greenhouse gases - Breaking news - Breaking News 24/7 - NEWS.com.au

THE Federal Government's preferred way to tackle global warming will go only a small way to stop greenhouse gases making the world hotter, a report has found.
The Australian Bureau of Agricultural and Resource Economics (ABARE) said a string of government plans to slow global warming would have only a marginal effect.
Australia, along with the United States, has refused to sign up to the Kyoto protocol aimed at cutting greenhouse gas emissions.
Instead, they back the creation of the Asia-Pacific Partnership on Clean Development and Climate, which includes countries such as China, to back low emission technologies.
Australia is also supporting research into the geo-sequestration of carbon dioxide, where greenhouse gases are theoretically stored underground.

But the ABARE research found these and other greenhouse gas friendly technologies such as hybrid vehicles would not stop global warming.
By 2050, greenhouses gases were likely to be 142 per cent above levels measured in 2001 if current polices were not changed.
Under the most widespread adoption of the Government's preferred policies, greenhouse gases would increase by more than 100 per cent.
More worryingly, the work would not achieve much in terms of slowing global warming.
"Even after accounting for the assumed widespread diffusion of cleaner technologies, the impact on global mean temperature is still expected to be significant," ABARE found.
The most recent temperature models suggest that by 2100, Earth would be at least 2.3 deg Celsius warmer.
There is also a 50 per cent chance the world will be 3.5 degrees hotter.
ABARE found that under all the policies being supported by Australia, global temperatures would be between 1.7 degrees and 2.6 degrees hotter.
The bureau's executive director, Brian Fisher, said part of the problem was that developing countries would ramp up their output of greenhouse gases in coming years.
He said it was clear something more than current policies would be required to make deep cuts into greenhouse gases.
"Global energy consumption and greenhouse gas emissions are projected to grow significantly in the future, driven by robust economic and population growth," he said.
"In order to achieve emissions cuts greater than are analysed in ABARE's report, concerted efforts by industry and government would be required to develop and transfer an additional portfolio of technologies across a wider range of sectors than has been analysed."
The report is more blunt in its assessment of what is required, saying deep cuts in greenhouse gas emissions would be "technically and economically challenging".
"Abatement actions across a range of sectors in all significant economies, greatly exceeding the degree of technological deployment considered in the enhanced technology scenarios modelled in this report, would be required," it found.
The report said all governments had a role to play in ensuring low emission technologies were spread across significant economies.
It backed more funding for research and development, the introduction of technology standards, carbon pricing, and collaborative efforts between governments and industries.
