We have not advocated for a cap on production; we've advocated for a cap on emissions. We think that would result in the future in a reduction in production because of changes in demand for the product globally.
I think one of the most important features of a cap-and-trade system or a carbon-pricing system that meets the level of a cap is that you have to be prepared to not protect the facilities that have a very high carbon cost, a very high cost of abatement, which is always what is done in these types of cap-and-trade type systems throughout the world. It weakens them, and it removes the effectiveness of them.
I think what we can expect to see is production not being replaced when production reaches the end of its economic life, but then, beyond 2030, the declining price of oil because the lower demand for oil would result in an actual reduction in production coming from our sector because we are very high cost, high carbon overall.
