I suppose it's entirely anecdotal on my part to hear of people, particularly smaller businesses, doing business in the States and having border difficulties. But I'm pleased, actually, to hear that you're not. That's good.
Your testimony primarily talked about the role of government in both incentives and penalties, trying to encourage behaviour that reduces the carbon footprint. In the case of Evergreen, you had a couple of fairly promising technologies that didn't quite go where you wanted them to go at the end of the day. In the overall situation, had there been in place a cap and trade system where they had been trying to acquire credits to reduce their carbon footprint, or a carbon tax system, would the decision of your potential customers have potentially been different?
