Sky-Trust model Appendix : Key Features of U.S. Sky Trust Here are the key features of the proposed U.S. Sky Trust. o Carbon emissions cap set initially at 1.346 billion tons, the 1990 level o Tradable carbon emission permits sold annually to energy companies at the top of the carbon chain. o All revenue from permit sales goes into a nationwide trust. o Trust pays equal annual dividends to all U.S. citizens (like the Alaska Permanent Fund). o Dividends can be placed tax-free in Individual Retirement Accounts or Individual Development Accounts for children. o Initial price ceiling on carbon emission permits of $25 a ton; ceiling rises 7 percent a year for four years. o Transition Fund to help those most adversely affected by higher carbon prices. Fund starts at 25 percent of permit revenue, declines 2.5 percent per year.
