Familiarisez-vous avec les ordres de grandeur du CO2 grâce à disCO2very

Face aux conséquences dévastatrices sur la planète de nos activités d'humains, faire les bons choix, même à une échelle personnelle, a un impact bien plus fort que ce que nous nous imaginons. Mais pour cela faut-il encore avoir la bonne information. En attendant qu'un projet plus précis et complet voit le jour (voir l'éco-score par exemple), j'ai passé ces derniers mois à développer disCO2very, un jeu de carte façon timeline pour se familiariser avec les ordres de grandeur du CO2. Il est sous licence libre (cela signifie que son code source est accessible) et utilise les données ouvertes d'Impact CO2, un projet de l'ADEME, l'agence gouvernementale française de la transition écologique.

Alors, arrivez-vous à classer ces quelques cartes de la moins émettrice à la plus émettrice ?

N'hésitez pas à me faire vos retours, et si vous voulez plus de détails, je présenterai ce projet au Capitole du Libre à Toulouse ce samedi à 11h30.

Here is a somewhat comical but also highly indignant commentary about the folly of “Net Zero by 2050”…
_______________________

We insiders — by which I mean anyone paying attention — know that the plan to mitigate the climate catastrophe with Net Zero by 2050 is complete bullshit. But maybe you’ve absorbed that knowledge without really understanding why. So let’s talk about it.

What does Net Zero actually mean? Net Zero is the point at which the CO2 burden in the atmosphere is no longer increasing. We’re still putting some up, but we’re also taking just as much out.

This definition immediately tips off two major problems.

The “still putting some up” part is a major issue because the fossil fuels industrial/political complex hears that and stops listening. The “still putting some up” part is their job, and somebody else can do the “take just as much out” part.

In other words, it's Business As Usual for fossil fuels, including continuing growth. Someone else can do the preserving-life-and-the-climate part.

The second obvious problem with Net Zero is the very idea of “taking just as much CO2 out of the atmosphere each year as the fossil fuel industry is adding to it each year.” We know of only two ways to reduce the CO2 load of the atmosphere. One is time. But CO2 stays in the atmosphere for thousands of years, so time is not on our side.

The other way to reduce CO2 is carbon capture and sequestration (CCS). Carbon is “captured” from the atmosphere using a chemical solvent that absorbs CO2, after which it can be buried in the ground where the CO2 will stay safely out of the atmosphere virtually forever.

CCS technology both does and does not exist.

CCS does exist in that there are many ingenious systems for doing it, including several pilot programs demonstrating direct air capture, the holy grail of CCS. Many fossil fuelled electricity generation plants have been removing CO2 from their smokestack emissions for decades. Unfortunately, much of the currently captured CO2 is being injected into played-out oil wells, forcing more of the remaining oil to be recoverable, to burn as fuel. Totally self-defeating, as far as reducing the CO2 load in the atmosphere.

But CCS also does NOT exist in terms of a significant contributor to Net Zero. They remove so little CO2 from the atmosphere, and at such a cost, as to make them completely impractical. To make a dent in carbon emissions, hundreds of thousands of CCS plants are needed, if not millions. The cost is prohibitive. Not to mention the carbon costs of manufacturing all those plants.

But surely CCS technology will improve over the next decade or two. Maybe someone will even find a miraculous breakthrough that will make it truly practical?

Sorry, but no. It’s not that there hasn’t been enough research into CCS. It has been heavily researched and the science is known. It’s actually some pretty simple chemistry. We can tweak around the efficiency edges, but there are no breakthroughs waiting in the wings to be discovered.
