Climate-warming pollution will be tracked by a new satellite

MethaneSAT, a satellite that detects methane emissions from oil and gas operations, was launched by Google and EDF on Friday in the US. MethaneSAT will create a global map of the emissions from the oil and gas industry. It will help regulators determine where there are leaks and reduce emissions, EDF added. MethaneSAT was built at an cost of $88 million.
