Attributing harmful practices to the companies responsible in a way that can affect financial markets requires:

1) spatially and temporally detecting where and when such practices took place;

2) attributing events to the companies responsible;

3) quantifying emissions’ impact on climate, ecosystem services and public health; and

4) reporting data to investors and traders in a format that is timely and actionable.

Each nano-satellite of our aerospace partner GHGSat orbits the Earth in a polar orbit (north-south) while the Earth turns (east-west) below it, enabling measurement of any source on the surface of the Earth, within days. Methane (CH4) and carbon dioxide (CO2) absorb light at different wavelengths, creating a “spectral fingerprint.” High-resolution spectrometers measure the amount of light absorbed at specific wavelengths, which in turn enables quantification of CH4 concentrations. These satellite-based instruments take hundreds of thousands of measurements around a source with a resolution of tens of meters. Such high resolution is key to successful attribution of point sources.
