Abstract
Despite the hopeful prediction in the New York Times story (quoted at the head of the article), we are very far from being able to use satellites to verify compliance with the Kyoto Protocol’s caps on greenhouse gas emissions. The problem is not only one of insufficiently developed or installed technology of Annex I states. “Satellite verification” would also mean changing the current system of reporting-and-review of state emissions, opening it up to independent scrutiny, and making it less forgiving of state evasiveness and ambiguity about emissions than it is now. Some states will be interested in this proposal and others will not. In any event, the current MRV system, built on bottom-up state reporting, will remain the dominant framework of international GHG emissions knowledge for the foreseeable future. To safeguard its own credibility, it must progressively be strengthened. In this article I outline the existing verification regime’s main shortcomings and argue that the most efficient way around them is to incorporate into the current MRV system top-down (satellite and surface) measurements, resolved by modeling software at the state level, and produced by independent scientific experts in cooperation with the UNFCCC.
