Attention greenhouse gas emitters: There’s a new eye in the sky that will soon be photographing your carbon footprint and selling the images to any and all. It’s a micro-satellite dubbed “Claire” (clear, bright, and clean in French) by its Montreal-based developer, GHGSat.
This microwave-oven-sized pollution paparazzo rocketed to a 512-kilometer-high orbit in mid-June care of the Indian Space Agency, with a mission to remotely measure the plumes of carbon dioxide and methane wafting up from myriad sources on Earth’s surface. Claire’s targets include power plants, natural gas fracking fields, rice paddies, and much more—just about any emissions source that someone with a checkbook (corporations, regulators, activists) wants tracked, according to GHGSat president Stéphane Germain.

In this month’s issue of IEEE Spectrum we spotlight the methane emissions overlooked by the U.S. EPA’s greenhouse gas inventory, and the satellite-based detector launching next year to map this “missing methane.” Last week the White House acknowledged EPA’s missing methane problem, and laid out a strategy to combat it. While promising to improve EPA’s inventory, including more use of top-down methane measurement, the White House also promised federal investment in ground-based methane sensing to plug leaky natural gas systems thought to be the source of much of the missing methane.
Action can’t come soon enough according to the Intergovernmental Panel on Climate Change (IPCC), which on Monday unveiled its latest report onClimate Change Impacts, Adaptation, and Vulnerability. The IPCC said “widespread and consequential” impacts are already visible and world leaders have only a few years to change course to avoid catastrophic warning. Methane is a major contributor according to the scientific body’s update on the physical basis for climate change, released last fall, which deemed methane to be up to 44 percent more potent as a warming agent than previously recognized.

The intensifying methane emissions debate has profound implications for climate and energy policy. Natural gas consumption is rising, and methane’s global warming impact is more than 30 times as much as that of carbon dioxide, molecule for molecule, and second only to carbon dioxide’s in today’s net climate impact …
