The image shows a sample of abnormal methane concentrations over 2019. The size and colour of the circles indicate the size and intensity of the plume detected. The redder the color, the higher the concentration of the methane plume. Source: Modified Copernicus Sentinel data (2019), processed by KayrrosScientists from a European technology startup have developed a new tool that tracts the location of emissions of methane, which is a greenhouse gas.

Using data captured by the Copernicus Sentinel-5P, an Earth observation satellite, along with data from ground sensors, social media and position tracking, Kayrros’ methane emission tracking tool identifies the location of global methane leaks, their sizes and potencies.

During testing of the methane emission tracking tool, researchers determined that at any one time in the world an estimated 100 high-volume methane emitting leaks are in progress, 50% of which come from regions with high oil and gas and coal mining activities, according to the team's findings.

Jean Bastin, product manager at Kayrros explained, "Over one year, those 100 leaks are releasing 20 megatonnes of methane, with around half of those attributable to the oil and gas sector and other heavy industries. This means that this sector emits an amount of methane that is equivalent to the yearly carbon dioxide emissions of both Germany and France combined."

Scientists at Kayrros believe that the tool will help improve the accuracy of methane emission measurements, which will potentially enable improved governmental decision-making on energy policies and serve to create a methane emissions baseline.
