Several existing vehicles could be used. I'm thinking of the tax credits that have been given to the wind industry, to mining, and to oil development, for example. These are well-known mechanisms. You also have flow-through shares and the benefits that come with them, the tax consequences.
So companies have an incentive to invest in those assets. That's what I call the carrot. If there's no regulatory framework to provide an incentive, offer them a carrot using the tax incentives in existing mechanisms.
