Certainly. If I don't quite answer your question, please reframe it.
When we look at our emissions in agriculture, I think we often hear that up to a quarter of global emissions are from agriculture, 3% of which are from production and use of fertilizers globally. One of our challenges is that whether we look at a national inventory or a company's emissions baseline, we are looking at estimates of our emissions. They're not measured directly but are estimated based on global emissions factors, and they don't necessarily capture reductions from differences in nitrogen use. Emissions factors that we use globally draw on available science, and the science will improve as we actually enhance measurement on the farm.
We are anticipating and monitoring some work globally, out of New Zealand and the Netherlands, which are experimenting to determine emissions levels from nitrogen-based fertilizer application. That emerging research will lead to a new set of emissions values that are lower than what we use now from the Intergovernmental Panel on Climate Change refinement estimates, so there's a potential for lower values to be applied as well, which we're focused on.
