If I were to encapsulate it, I'd say it's in the manufacturing, sale, design, development, or production of technologies that can contribute to an environmental benefit. That could include renewable energy, production energy, or conservation technologies, as Thomas has mentioned, green building technologies and approaches, design, and so on. So the green economy encapsulates a number of those types of activities.
In terms of a threshold, whether it's a GHG thing or improving water, I don't think we would define it using one single measure. The fact of the matter is, it's a growing industry, and the fact of the matter is, Canada is buying most of its technology from abroad. There is an opportunity here to develop homegrown solutions and to assist with the challenge we have right now in the economy.
