There were two questions there: what's a fixed cap, and how would the fixed caps, as set under this act, compare with those in other countries? The answer to the second question is that it's too early to answer that question. The answer to that question depends on what number this government comes forward with. What will the targets be? That's an issue for you to discuss with the minister and his cabinet colleagues.
A cap is a numerical limit on emissions. It could be set on a facility basis, on a sector basis, or on a multiple sector basis, but a cap is just what it sounds like: you can't go above this limit. That's what it means.
In terms of how it compares to other countries, as I answered earlier, it depends on what the number is.
