Finance committee  I would say that 60% of our CO2 comes from the heating process in the rock, and the other 40% comes from the actual fuel. We were following very closely all of the techniques, all of the technology, around capturing and sequestering CO2, but our main focus today is to invest in other technologies and to try, in effect, to produce more with the same amount or less.

Finance committee  On an intensity basis today. We are actually one of the lowest emitters of CO2 in the cement sector in Canada.

Finance committee  Yes, I would prefer to delegate that one to the tax group. We're specifically interested in machinery and things that are--

Finance committee  Thank you. We've been working well with government over the last six years on cap and trade legislation. We're well-positioned as a company and as a segment to work with government in reducing greenhouse gases. We've seen significant reductions in NOx and SOx, as part of the Ontario regulation.

Finance committee  Yes. We trade under Dufferin Concrete. Cement and aggregate, along with water and some other additives, go into making concrete.

Finance committee  Yes.

Finance committee  Yes, the whole infrastructure program is very good for us. We're seeing some good growth in both construction and concrete, but not so much in cement and aggregate at the moment. We're seeing some infrastructure money right now, and it is having an impact. Trenton air force base is one of our key projects.

Finance committee  At the end of the day, when we're finished our infrastructure spending and these projects are done, we have to rely on the private developers. The other message we have for government, both federally and provincially, is to invest in the triple Ps and get other sources of funding there, because there is still a deficit in our infrastructure program.

Finance committee  We're the dry cement product, yes.

Finance committee  From our perspective, we believe the government has various levers available to it within the EI system to strike the right balance in terms of what's necessary. I think from a practical point of view, trying to have a more measured approach to it over time, to allow us to get out of this cycle, would be something we would see as beneficial.

Finance committee  Thank you, Mr. Chairman, and thank you, members of the committee. I'm here today with Angela Burton, who is our vice-president of communications and public affairs. I'm senior vice-president with Holcim Canada. Before I move on to talk about our recommendations, I'd like to take a moment to review the history of Holcim and make you a little more familiar with Holcim Canada.
