Tony Blair has called on world leaders to incorporate green technology into their plans to reduce carbon emissions.

The former British prime minister said a practical and realistic deal needs to be agreed by delegates at the upcoming summit on climate change in Copenhagen.

Mr Blair stated that any accord should incorporate the greater use of eco-friendly technology, particularly in buildings, cars and power stations.

However, he insisted that world leaders cannot afford to become too concerned with exact facts and figures when trying to come up with a deal on safeguarding our ecological future.

"We need to get an agreement that sets the world on a new path of sustainable consumption without getting obsessed with precise percentages," he commented.

Mr Blair added that any agreement on tackling climate change could lead to carbon emissions peaking "more quickly than many people think".

This comes shortly after ecological pressure group Friends of the Earth accused the world's richest nations of proposing "pitifully inadequate" targets for reducing carbon emissions.
