As I said, there are two things: performance and best available technology. If you have a performance goal, which is carbon intensity of some kind, and you have a commitment to making sure that all technologies are considered and that the best available technology is the standard, then that's the way to do it.
I'll give you an example of how agricultural services can be used for methane mitigation, for watershed services, for many things. In Halifax, for example, they have a nitrate problem in the harbour. You could use water treatment technology to address the methane problem. Well, you could also ask the farmers to use land-use services such that a certain proportion of the land was used as a watershed to make sure that no nitrate actually went into the harbour. The best available technology in this case is land-use services; it's not water treatment. The difference in cost is $1,000 for land-use services and $500,000 for water treatment.
We need to have performance-based approaches that require best available technologies and are cognizant of those best available technologies. Some of them will be traditional clean technologies, some of them will be agricultural.
