Mr. Gavin Harte:

We are working on the science of the matter, and the atmosphere can absorb so much carbon. We are looking at our part in the process. It is a technical matter as to where we take a reference but ultimately the purpose of the Bill is to achieve a reduction in our emissions in the long term. We are looking to achieve a low-carbon society, which in our view would be an economy with an 80% reduction in emissions by 2050.
