There are definitely two pieces there that you have picked up on. One is the innovation in products. That would be slow-release inhibitors, etc. I'll come back to that in a minute.
When I'm referencing low-carbon or carbon-free fertilizers, it's in the production context. We have a continuum. We start with carbon capture. That is step one. From there we could look at different production processes, but that will involve a rebuild of assets. It would begin with autothermal reforming, and we could then get into methane pyrolysis as another low-carbon method and explore that. UItimately, we are on a road map to green ammonia, which would give us access to renewables.
What's exciting is that whether you're in production or process, if we are using the carrot and not the stick, we are going to facilitate an agenda of innovation around decarbonizing agriculture. I think that's an important part of the picture, as are productivity, reductions and sequestering carbon in our soil.
