Mr. Stephen Treacy:

We will need to come back to the committee with the full picture in terms of soil emissions, etc. In terms of energy, it is approximately 2.6 million tonnes, residential is approximately 0.8 million tonnes and horticulture extraction is 0.5 million tonnes. We are talking about at least over 4 million tonnes, just on extraction and burning. As I stated, I would like to come back with a more detailed response to give the committee the full information.
