I thank my hon. Friend for that contribution; he has hit the nail on the head. The Bill aims to encourage much more specific definitions in these areas.
The EU has set emission limits for other pollutants—sulphur dioxide, for example—so the concept behind the Bill is already well established. Perhaps the most well known example of an emissions performance standard for CO2 is the one applied to power plants in the state of California—and, indeed, it is being extended to other states in the US. It was implemented in California in 2007 and it requires that any new power station—or, for that matter, any energy imported into the state—meets carbon intensity limits. These are set so that new unabated coal plants without CCS cannot go ahead. If CCS is added to a new plant, however, it complies with the standard and it can proceed—precisely the point that my hon. Friend David Howarth made.
