GHGSat is a private company on a mission to become the global reference for remote sensing of greenhouse gas (GHG), air quality gas, and other trace gas emissions from any source in the world.

In June 2016, GHGSat launched the world’s first high-resolution satellite capable of measuring greenhouse gas (CO2 & CH4) emissions from any industrial facility in the world. GHGSat is using this unique satellite and its patented technology to provide greenhouse gas emissions monitoring data and services globally,with better accuracy and at at a fraction of the cost of comparable alternatives. Some of the sites monitored by GHGSat are identified by orange dots in the image on the right.


Level 1B. Level 1A data that has been processed to sensor units. Surface Reflectance Image.

Level 2. Derived geophysical variables at the same resolution and ocation as the Level 1 source data. Abundance Dataset.

Level 3. Variables mapped on uniform space-time grids, usually with some completeness and consistency. Concetration Maps.

Level 4. Model output or results from analyses of lower level data (ie. variables derived from multiple measurements). Monitoring & Emission Rates


  • GHGSat offers custom analysis, using GHGSat satellite imagery and other sources, on an exclusive basis to each customer, in much the same way as environmental consulting services are offered today. Examples:

    Monitoring of targeted sites (e.g. natural gas leaks from pipelines)
    • Emission rate estimation, including inventory analysis emission rate of species, using single scene abundance dataset, for instantaneous measurements, or averaged over a full year.

    Other products and value-added services are available from GHGSat on a case-by-case basis:

    Augmented analysis of emissions, using additional data such as facility data provided by facility operators
    Mosaics of commercial satellite imagery products
    Trending analysis of emissions from individual sites, or grouped sites in a region, within the constraints imposed by data exclusivity arrangements within individual customers

Owners of industrial facilities are now able to monitor all of their facilities, local or remote, anywhere in the world, with a common technology, in near-real-time. Significantly improved emissions information is enabling industries to better measure, control, and ultimately reduce emissions of GHGs. GHGSat satellites orbit the earth detecting methane emissions at a 25m resolution.


Methane is the powerful greenhouse gas that’s not being talked about.

Invisible to the eye, it has 84 times the global warming potential of carbon dioxide, over 20 years. To understand what’s happening, we first need to see it. PULSE GHGSat is a unique interactive tool using cutting-edge technology to reveal methane concentrations around the world – in the highest resolution ever.
