Satellite Network to Pursue CO2 Super-Emitters

A constellation of satellites is going to be flown this decade to undertake to pinpoint significant releases of climate-changing gases, especially CO2 and methane.

The initiative is being led by an American non-profit organization called Carbon Mapper.

It will use technology developed by the US space agency over the past decade.

The satellites – 20 approximately – are going to be built and flown by San Francisco’s Planet company.

There are already quite a few satellites within the sky that monitor greenhouse gases, but the potential is way from perfect.

Most of those spacecrafts can sense the likes of methane over very large areas but have a poor resolution at the local level, at the size, say, of a leaking pipeline. and people systems that will capture this detail will lack the wide-area coverage and therefore the timely return to a specific location.

The Carbon Mapper project wants to repair this either-or-situation by flying multiple high-resolution (30m) sensors which will deliver a daily view, or better.

They will search for super-emitters – the actors liable for large releases of greenhouse gases. These would come with oil and gas infrastructure, or perhaps poorly managed landfills and enormous dairy factory facilities.

Often these emitters want to understand they need a drag but just do not have the info to require action.

“What we’ve learned is that call support system that focuses just at the extent of nation-states, or countries, are necessary but not sufficient. we actually got to get right down to the size of individual facilities, and even individual pieces of kit, if we’re getting to have an impression across civil society,” explained Riley Duren, Carbon Mapper’s CEO and a search scientist at the University of Arizona.

“Super-emitters are often intermittent but they’re also disproportionately liable for the entire emissions. that means low-hanging fruit because if you’ll identify and fix them, you’ll get an enormous bang for your buck,” he told the news channel.

The aim is to place the satellite data within the hands of everyone, and with the required tools also to be ready to understand and use that information.

The project is being supported in large part by philanthropy – from the likes of the high-water Foundation and Bloomberg.

It also has buy-in from the US State of California. State law commits California to scale back its greenhouse emission emissions by 40% below 1990 levels by 2030, and to eventually get to carbon neutrality.

“We can’t meet those targets without attention on methane (CH4), CO2 (CO2), and hydrofluorocarbons (HFCs),” said Richard Corey, a military officer at California’s Air Resources Board.

“Whether you’re talking about oil and gas operations, landfills, wastewater treatment facilities – we all know that if we will identify leaks efficiently, they will be repaired. It’s about getting that information ahead of parents in a timely way. which will make it actionable.”
