Cost, lifecycle accounting and policy context
Choose the carbon pathway
Start with the fate of the carbon. Captured CO2 can be rebuilt into products, stored out of circulation, or counted incorrectly if the boundary is wrong.
Capture
Take CO2 out of a gas stream
Separating CO2 from flue gas, from process gas, or from ambient air — the step that produces a concentrated stream everything downstream depends on.
ExploreCaptureConversion
Turn CO2 into something else
Breaking the C=O bond and rebuilding the carbon into fuels, chemicals and polymers, using electrons, heat, light or enzymes.
ExploreConversionStorage
Put carbon away and keep it there
Placing CO2 somewhere it stays for centuries to millions of years — pore space in rock, reactive minerals, or the deep ocean.
ExploreStorageUtilization
Put captured carbon to work
Using CO2-derived carbon in fuels, chemicals and building materials, where the climate benefit depends entirely on how long it stays put.
ExploreUtilizationCross-cutting
Cost, life-cycle accounting and regulation decide which technically sound processes ever get built. Often the reason a good technology does not deploy.

Before a tonne becomes a climate claim
Carbon technologies change meaning with source, energy supply, product lifetime and storage permanence. Pick a route to see the claim it can support and the evidence that has to survive scrutiny.
Stage
capture
Readiness
TRL 6–7 — pilot
Direct air capture
Removal candidate
- Carbon fate
- Pulled from ambient air, then only becomes removal if stored durably.
- Credible when
- Credible when lifecycle emissions are lower than captured CO2 and storage is permanent.
- Failure mode
- The capture figure alone is not the removal figure.
Evidence to demand
- Energy source and full lifecycle emissions
- Storage permanence and monitoring plan
- Whether quoted costs are measured operation or future projection
Evidence
Claims under scrutiny
A public queue for carbon claims that need a boundary check: captured versus removed, stored versus used, pilot result versus durable climate outcome.
No public claim checks yet. A useful first one is a sentence from a deck, article or website where the carbon accounting feels too neat.
Mechanism before market story
Each route starts with what is physically happening, then moves to maturity, limits and open technical questions.
Claims stay attached to sources
The site currently organizes 73 verified sources, with citations linked through DOI records instead of free-floating references.
Uncomfortable constraints stay visible
Energy supply, permanence, product lifetime, sorbent loss and accounting boundaries are part of the main story, not fine print.
