Ultimately, the 40% target is what each department should shoot for, so again, we've made public how each department has progressed against that target. Again, that's on the website and available.
We're asking all departments to hit that target, but you can also look at the distribution, if you will, of the emissions. There are a few departments that have much higher emissions than others, so there might be more cost-effective ways in certain departments, or other ways. There are a lot of ways we can get there, but ultimately every department should shoot for that target.
