Start low, increase steadily to meet emissions targets.
Canada recently introduced a carbon tax at the federal level (for provinces that did not price carbon themselves), and returns 90% back to those province's taxpayers via tax credits. This makes it a progressive tax; if you lived an emissions-free lifestyle you'd just get free money, if you're around average the rebate would offset the carbon tax, if you're a high consumer you pay more.
