"#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

Evero’s Ince biomass plant will be converted into the UK’s first BECCS site by 2029, capturing 217,000 t CO₂/year, processing 170,000 t waste wood, and powering 100,000+ homes.
🚨New research out on US public perceptions of #SolarGeoengineering:
More Americans oppose SRM research than support it, and 1 in 5 believe government-led atmospheric modification is already underway.
DETAILS🧵1/11
2/ Using 64 interviews, 10 focus groups, and a survey of 3,076 Americans, the study found strong initial rejection of solar radiation modification (#SRM) as a research priority.
Skepticism, fear of unintended consequences, and concern over “playing God” were dominant themes.
3/ Only 32.6% supported further SRM research. A notable 43.7% opposed it. For comparison, support was ~80% in similar studies from a decade ago. Enthusiastic support is now virtually nonexistent in qualitative responses.

Germany’s 2026 draft budget allocated €111 million for negative emissions in 2026 and a further €320 million in subsequent years. A new federal department has also been set up to focus on carbon removal.
🚨How does #SolarGeoengineering affect air pollution & public health?
New study using a cutting-edge Earth system model shows that #SAI has only modest effects on PM₂.₅ & ozone-related mortality & these impacts are mostly due to climate shifts, not aerosol deposition.🧵1/8
2/ Using CESM2-WACCM6 simulations across three scenarios (SSP2-4.5 baseline, ARISE-SAI-1.5, ARISE-SAI-1.0), the study quantifies global mortality attributable to ozone (O₃) & fine particulate matter (PM₂.₅) under future SAI deployment targeting 1.5°C and 1.0°C warming levels.
3/ Findings:
In the ARISE-SAI-1.5 scenario, maintaining global mean temp at 1.5°C above pre-industrial levels via SAI results in:
- 1.26% reduction in ozone-related mortality
- 0.86% increase in PM₂.₅-related mortality during 2060–2069, relative to SSP2-4.5.

Chestnut Carbon secured up to $210M in non-recourse financing, led by J.P. Morgan for its afforestation project, marking a first-of-its-kind deal in the US carbon removal space.
🚨Scientists have discovered a common soil bacterium, Bacillus megaterium, that can rapidly remove CO2 from the atmosphere by transforming it into solid limestone (calcium carbonate) within 24 hours, without creating toxic byproducts.

2/ Microbially induced calcite precipitation (MICP) is a technique where microbes precipitate CaCO₃, often used in eco-friendly building materials.
Most MICP uses urease to break down urea, which produces ammonium, a problematic byproduct.
3/ Bacillus megaterium is unique in a sense, it contains both urease and carbonic anhydrase (CA) enzymes. The latter allows it to fix CO₂ directly without needing urea.
But which pathway dominates? This study investigated that.
