In Washington today, three responses are being offered to the problems caused by carbon emissions.

Do nothing
Some people say there's no need to limit carbon emissions.

Give the sky to polluters
Another set of people favor a cap on total emissions and a market-based system in which tradable emission permits are given free to historic polluters.

Create a Sky Trust
A third group of people favor a cap on total emissions and a market-based system in which tradable emission permits are put in trust for all citizens, current and future.

The Sky Trust has broad political appeal. Here's why:

• No new taxes
• No government ownership or regulation
• No corporate welfare
• Pro-family and pro-child
• Market pricing
• Citizens' property rights expanded
• One person, one share
• Polluters pay
• People who conserve are rewarded
