For the first one, I don't know the technical answer. I can just say that for the Alberta program I flagged earlier, the average grant size was $6,000 for retrofits, and that led to about 40 retrofits in Alberta. That's different from the $25,000 I mentioned. I don't know if that means the technology was different, but it's something we should all look into, I suppose, me included.
For the second question, there is so much more to do. You're flagging soil carbons, so I'll go with that one. Absolutely, that's an incredible resource that farmers are responsible for protecting on millions of acres across Canada. It's better for production if we have better soil health; it's better for the climate; it's better for water and for biodiversity. There are so many great reasons.
Other folks here, including Fawn, have talked about the potential of offsets. This is an important opportunity on the horizon. I understand that two protocols are at least being prioritized. What we want to remember about offset protocols, though, and payments is that we want to be sure they're changing the status quo. Ultimately, to lead to real emission reductions, we need to be sure offset payments are actually generating new emission reductions. The investment we saw in the budget yesterday is so important if for no reason other than to create an important public bridge to incent behaviour change on our farms and to help share that upfront cost, so that if offset markets come into place, we'll be well supported to really scale up a transition to improve soil health.
You mentioned mapping. I think that's so important. We need to understand better the potential of our soil to sequester carbon as well as which practices have the highest impact. In our work for the budget submission, even though we worked with some of the best GHG scientists in Canadian agriculture, who have participated in the Kyoto protocol and who have been at this for decades, we still struggled to find enough data to be very, very confident in the megatonne reductions on parts. So more research is needed, paired with more incentives direct to farmers to adopt these practices.
