I believe the report was published last week.
As far as the policies on carbon pricing or mechanisms to give carbon a value are concerned, that is a political and not a technological issue. What is clearly a technological aspect is that we can really see things over the long term and do projections for the next 20 to 50 years. The carbon capture and storage projects, for example, can be deployed on a very large scale.
We therefore want to ensure that we are ready to deploy such projects on a major scale and that we understand the parameters well, within the context of seeking to minimize greenhouse gases.
