MEXICO CITY (Reuters) - Satellites recorded another large methane leak at an offshore platform belonging to Mexico's Pemex in August, according to exclusive data shared with Reuters, even as pressure mounts on the state oil company to reduce these emissions.

Three satellites recorded images of methane plumes at the Ku-Maloob-Zaap oil field cluster in the Gulf of Mexico during six days between Aug 5 and Aug 29, said Itziar Irakulis-Loitxate, a scientist from the Polytechnic University of Valencia.
