Finally listened to the conference call1. Carbon revenue: As Dosperros mentioned, they are already working on a carbon monetization scheme in the voluntary carbon market. They said it is "on track" to start generating income in Q2 or Q3 2022. They wouldn't disclose any estimates, but suggested the amount would initially not be overwhelming. In other words they seem to be dipping a toe in the carbon market. Strangely, I couldn't find a mention of this in the MD&A - seems a little less than professional to me.
2. Sustainability of the payout: This was not mentioned on the presentation, and nobody asked a question about it. Also not mentioned in the MD&A as far as I can see. I may send a question to management about this.
