Mapping methane emissions on a global scale : An important new tool to combat climate change is now available. Using data from the Copernicus Sentinel-5P satellite, this new technology makes it possible to track and attribute methane emissions around the world. Mapping methane emissions on a global scale Methane is the second most important greenhouse gas and its concentration in the atmosphere is currently increasing at a rate. of around 1% per year. It effectively absorbs heat from the sun, more so than carbon dioxide, and contributes significantly to the warming of the atmosphere. As a result, there is a growing demand to track and regulate methane emissions. Scientists from Kayrros, a European technology start-up, have recently developed a platform to monitor methane emissions on a global scale. Their findings come from a technology that leverages  Copernicus Sentinel-5P  data along with additional information from a range of other sources – such as ground sensor da
