First, I'll go to the end and go back to the example I gave of Questor, which has the incinerator technology. To the extent there was an additional carbon cost, it could make the difference to say maybe I'll incinerate versus doing flaring. I think there's an example that would speak to what you're getting at, that carbon taxes could create an incentive.
Going back to the question I didn't answer before though, as does Evergreen, I like the broader definition of clean tech that talks about environmental benefits and not just carbon benefits. I'll give you the example of Oslo, Norway, that has adopted, as many places in Europe did, the new high-efficiency diesel engines, which have a lower carbon footprint, but people forgot about the acid rain problems of the 1960s and 1970s, and the smog problems that our generation was able to solve. Now people with diesel cars can only drive into the centre of Oslo every second day because smog came back.
Therefore, I think we need to expand this idea of what a clean technology is to some of the things that Evergreen has, which may not be directly related to greenhouse gases but nonetheless are very germane to a better environment in terms of the potential to clean up contaminants or other actual pollutants in the environment, versus carbon. I think the point is in some ways—
