That thing that interests me is that it is a clear market failure. 30 year bonds pay a higher interest rate than 5 year bonds. So one would think there is incentive to plan better for a building that lasts for 30 years. But we are changing the climate and other things with effects that will be felt long before 30 years. The U.S. Treasury does not offer bonds beyond 30 years, so presumably the entire system can't plan for a time horizon beyond that.
