In its third and final key findings, the IPCC panel reports:
■ A cost of $US20-50 a tonne of atmospheric carbon would have a big impact on cutting harmful emissions. "It could lead to a power generation sector with low greenhouse gas emission by 2050."
■ This would allow renewable energy to have a 30 to 35 per cent share of total electricity supply by 2030.
■ Nuclear power would provide only an additional 2 per cent of the world's electricity supply by 2030 because it is too expensive, and "safety, weapons proliferation and waste remain as constraints".
■ Clean coal technology has the potential to make an important contribution by 2030.
■ Improving efficiency of energy supply and use would play a key role in reducing emissions by up to 30 billion tonnes a year by 2030.

clipped from www.smh.com.au THE cost of saving the planet from catastrophic climate change will not be a major burden on the world economy, shaving only a small amount from global growth if governments act now, says a report by the United Nations expert panel on climate change. A former CSIRO climate chief, Dr Graeme Pearman, of Monash University, said the impact on a healthy economy would be small. "The cost of letting climate change happen is a lot more than the cost of mitigation." Stabilising greenhouse gas emissions at a level that can limit the temperature rise to 2 to 3 degrees would reduce annual gross domestic product growth rates by only 0.12 per cent, the report said. Global emissions would need to be slashed between 50 and 85 per cent by 2050 from levels in 2000. |

Many people in the world goes to the work by car, and all day are siting in front of the computer. I am sure, many of them would prefer to work from home, making the same tasks. In this way we could reduce the gas emissions, just help employees to promote this possibility.
