"#NegativeEmissionsTechnologies are needed to achieve #NetZero emissions, but their deployment will depend on regional & national circumstances, technology availability, & decarbonization strategies."
In this regard, a new study is done. Details below in a 🧵 1/7
The recent paper reviews "the literature and maps the role of Process Integration (PI) in #NETs deployment." 2/7
"Techniques such as mathematical programming, pinch analysis (PA), process graphs (P-graphs), are powerful methods for planning #NET systems under resource or footprint constraints." 3/7
"Other methods such as multi-criteria decision analysis (MCDA), marginal abatement cost curves, causality maps, and machine learning (ML) are also discussed," in this study. 4/7
"Current literature focuses mainly on bioenergy with carbon capture and storage (#BECCS) and afforestation/reforestation (#AR), but other #NETs need to be integrated into future models for large-scale #decarbonization," study found. 5/7

Stockholm Exergi announced its decision to build one of the world’s largest BECCS facilities, a $1.3B project set to remove ~800,000 tonnes of CO₂ annually and be operational by 2028.
Enhanced rock weathering startup @EionCarbon secured $33M carbon removal offtake deal with Frontier to remove 78,707 tons of CO₂ (2027–2030) by applying olivine on U.S. Midwest and South farmland.
🚨How do political affiliations shape attitudes toward #SolarGeoengineering?🚨
A conjoint experiment with 2,123 US voters finds that partisanship outweighs message framing—meaning who delivers the message matters more than what the message says.
DETAILS🧵1/9
2/ The discourse on SG as a climate solution is evolving, but public perceptions—especially in the polarized US landscape—remain underexplored. This study () examines how different narratives & partisan sources influence attitudes.nature.com/articles/s4416…
3/Researchers tested 3 SG narratives:
-Complementary: SG as an add-on to emissions cuts
-Substitutive: SG as a standalone climate solution
-Moral hazard: SG as a risky distraction
& the source(Democratic or Republican, researcher or podcaster) to simulate a realistic info env

BlueShift company that aims to unlock sustainable, domestic critical mineral supplies while providing affordable ocean carbon removal exited stealth with $2.1M in pre-seed funding.
Seattle-area startup Homeostasis has secured a $600,000 pre-seed investment to develop technology that removes atmospheric CO₂ and converts it into graphite, which has industrial uses.
Scientists at @NorthwesternU have developed a NEW carbon-negative building material using seawater, electricity & CO₂.
How does it work? And how much CO₂ can it store? Read on:🧵1/12
2/ This study expands on earlier research that focuses on storing CO2 in concrete [nature.com/articles/s4324…] & using electricity to treat seawater for cementing marine soils [nature.com/articles/s4324…].
Researchers are now injecting CO2 while applying electricity to seawater in lab.
3/ PROCESS
To generate the carbon-negative material, the researchers started by inserting electrodes into seawater & applying an electric current. The low electrical current splits water molecules into hydrogen gas (a clean fuel with various applications) & hydroxide ions.
A global survey of 30,000+ people across 30 countries reveals how emotions—hope, fear, anger—shape perceptions of climate change & support for interventions like #CDR & #SRM.
Does hope drive action—or is fear the real motivator? Read on:🧵1/8
2/ To measure “climate emotions” globally, researchers (@ChadM_Baum, Elina Brutschin, Livia Fritz, @BenjaminSovaco1) from Aarhus University & IIASA surveyed adults in 19 languages from Aug–Dec 2022.
Here are some of the findings:
3/ Among the 12 most hopeful countries about climate change, there were 11 developing and emerging economies of the Global South (including Nigeria, Kenya, India and Indonesia).
The only Global North country in this group? The United States.
