The Satellite Point source Emissions Completeness Tool (SPECT) is an interactive platform that enables users to compare and contrast the capabilities of satellite technologies — both existing and planned — according to a metric of completeness. Completeness refers to the ability to detect global methane super-emitters, or large point sources of methane greater than 25 kg/hr. The metric allows for a more direct comparison between satellites based on the percentage of high-emission methane sources they are able to detect. You can learn more by reading RMI’s accompanying report.
SPECT is designed to help policymakers, regulators, NGOs, and scientists who are actively designing programs and policies to use remote monitoring to help achieve their climate goals, such as the Paris Agreement or the Global Methane Pledge. The metric of completeness can enable civil society to compare satellites to other measurement technologies and maximize the mitigation potential of abatement programs. By offering a way to compare detection across different satellites, it can also help operators identify which instruments offer the best prospect of detecting leaks and assess the success of implemented mitigation strategies. It is intended to be dynamic and enable continuous improvement through engagement with technology providers and users.
