Mr. Noel Gavigan:

I will clarify a few things. A question came up on how CO2 is accounted for. One tends to look at where the source of carbon is in renewable energies. Carbon from fossil fuels comes from a geological store and that is being released into the atmosphere. Anything that is cyclical has a different category. I will give the committee a base idea on that. The alternative to putting material back into a biogas plant, such as waste food, is composting or letting it break down during which the CO2 will be released anyway. The alternative to slurry is putting it out on land where the CO2 is released, as it is broken down in the soil.
