US comes clean

Some of the world's biggest producers of greenhouse gases have unveiled plans to cut emissions by exporting new technology rather than setting limits on their own industries.

The US, Japan, Australia, India, China and South Korea announced the plans, which have been worked on secretly over the past year, at an event in Laos.

They clear the way for the US and Australia in particular to export a variety of renewable energy and pollution-reducing technologies to developing countries, instead of cutting emissions themselves.

Areas of special focus will include nanotechnologies, advanced biotechnologies and next-generation nuclear fission and fusion, the six partner countries said.

They claimed it would allow the world to take action on climate change in a way that does not interfere with any individual country’s economic growth.

According to a White House bulletin, the deal will aim to build on existing co-operation between the six countries by promoting clean coal use, expanding nuclear power programmes, promoting energy efficiency and increasing the reliance on sources of energy other than fossil fuel.
