"We're increasingly at risk of going over the carbon budget and the temperature limit. We need extra efforts to reach net-negative emissions and bring down global warming," says PIK director Ottmar #Edenhofer, Chair of the European Scientific Advisory Board on Climate Change, presenting the Board’s latest recommendations on carbon dioxide removals #CDR to the European Parliament’s ENVI Committee.

#EU exploring weaker 2040 climate goal

The European Commission wants to keep a 90 percent #emissions-cutting target but to change how countries calculate their progress.

The options being discussed range from allowing countries to defer steeper cuts to letting them count carbon reductions they pay for in other countries. Another idea would be to lean more on carbon that forests or technology can remove from the air."

POLITICO · EU exploring weaker 2040 climate goalVon Karl Mathiesen

Well, that's a very quick "unsubscribe". Utter nonsense. The emerging #CDR industry needs (is begging for) smart regulation....The #EU doing so is not "micromanaging"

All CO2 emissions can be brought to zero, and this should be priority #1. Haphazardly throwing CDR at existing emissions is not a "tool to reach net zero faster", but rather a recipe for mitigation deterrence

Only then, once we (hopefully) reach net zero, might CDR be a useful tool to push negative emissions forward

We've just connected our first customers to Open Banking within Rounded. It's taken years, but we've finally taken the first step to removing screen scraping for bank feeds.
Having said that, the quality of data from some of the 2nd tier banks is very disappointing.

The daunting physics of carbon removal

"The [American Physical Society] report summarizes the current state of available carbon dioxide removal (#CDR) technologies and outlines recommendations for policymakers.

Above all, the report emphasizes that in most cases, cutting current carbon emissions is easier and less costly than large-scale, engineered carbon dioxide removal efforts may ever be."

"For most countries around the world, sourcing energy entirely from wind, solar, geothermal, and hydropower by 2050 would reduce their #energy needs and costs, improve air quality, and help slow climate change, according to a study.

These benefits, the authors say, could be realized at a fraction of the cost of implementing technologies that remove carbon dioxide (CO2) from the air and capture it from stationary emitters like industrial smokestacks."

Tech Xplore · Carbon capture more costly than switching to renewables, researchers findVon Josie Garthwaite

New Earth system #modeling paper published: iopscience.iop.org/article/10.

Moritz Adam and co-authors are benchmarking carbon dioxide removal #CDR through Sun-driven #co2 conversion.

Main takeaways:

▶️ Unwanted indirect climate effects are negligible
▶️ Energy requirements are substantial
▶️ Achieving high efficiencies is crucial to avoiding land use conflicts
▶️ Accelerating emission reductions now is essential!

Das System war schnell (und ich auch ;)). Die Aufzeichnung zu meinem Vortrag über DACCS ist hier verlinkt:

Freu mich auch über Rückmeldungen oder Diskussionen hier und interessiere mich für die Meinungen darüber hier in der Community.

Potential #IPCC rule changes could award planned carbon savings from burning #wood rather than fossil fuels to the wood exporter, not the importer, as per current EU accounting rules... Accounting is much more policy than science.

The Guardian · UK gambling with climate targets over carbon capture, say campaignersVon Jillian Ambrose

The good news (academic.oup.com/plankt/articl) - the high pressure of the deep #sea decreases the degradation rate of organic #carbon, so biomass that makes the deep sea stay there longer.
The bad news (int-res.com/abstracts/meps/v67) - temperature increases the degradation rate, and the deep #ocean is getting warmer.
Combined, there are some interesting implications for organic-based
#CDR.
